Unlike traditional round log cabins, interlocking square log homes use timbers milled flat on four sides (or flat on the top and bottom with smooth outer faces). They feature engineered tongue-and-groove horizontal profiles and precision CNC-cut corner joints (such as dovetail, saddle notch, or modern flush "city corners").

When stacked, these logs lock tightly together, forming a self-aligning, airtight structural wall shell with clean, modern architectural lines.

A. Solid Square Logs

• Best For: Secondary dwellings, garden offices, holiday cabins, or warm/moderate climates.
• Characteristics: Pure solid timber milled from single trees. Offers natural character and high thermal mass.
• Consideration: Undergoes natural moisture loss, resulting in minor checking (cracks) and settling over the first few years.

B. Glulam (Glued Laminated) Square Logs

• Best For: Primary residences, multi-storey builds, and modern designs with large glass spans.
• Characteristics: Made by bonding multiple kiln-dried timber slats together under high pressure.
• Advantages: Extremely strong and stable. Resists twisting, cracking, and warping, resulting in near-zero structural settling.

C. Insulated Double-Log Systems

• Best For: Meeting strict energy codes (such as NZEB, Passivhaus, or UK/EU Building Regulations).
• Characteristics: Consists of an outer square log wall, a central cavity filled with high-density insulation (e.g., wood fibre or cellulose), and an inner square log face.
• Thermal Performance: Delivers ultra-low  -values (  to  ) while preserving a real wood aesthetic inside and out.

When evaluating manufacturers and suppliers, verify that your timber package meets these benchmark standards:

• Timber Origin: Choose slow-grown Northern European or Alpine softwoods (such as Nordic Pine or Spruce). Dense growth rings provide far greater strength and dimensional stability than fast-grown timber.
• Moisture Content: Ensure logs are kiln-dried to a moisture content below 18%. This minimizes shrinkage and pest risks.
• Structural Certification: Verify components carry standard structural grading marks (e.g., CE or UKCA under EN 14081) and structural calculations adhering to Eurocode 5 (or local equivalent).
• Sustainability: Confirm wood is harvested from certified sustainable forests (FSC or PEFC).

• Smooth Interior Finishing: Flat vertical inner walls make it easy to mount kitchen cabinets, fit wardrobes, and tile bathrooms without custom scribing or notch-work.
• Hidden Utilities: Factory-milled log packages feature pre-drilled vertical conduits inside the logs. Electrical cables are pulled through during wall stacking, leaving no exposed trunking.
• Superior Weather Shedding: Square logs feature engineered outer bevels and drip edges that shed rain away from seam joints, preventing water from pooling between horizontal layers.

1. Site & Planning Approval: Secure land surveys (soil/topography) and local planning consent. Ensure ridge height, boundary offsets, and regional aesthetic rules are satisfied.
2. Factory Design & Production: Finalize floor plans and electrical routes before factory milling. Changing pre-drilled service channels once logs are cut is difficult and costly.
3. Substructure Preparation: Install concrete slab, raft, or insulated screw-pile foundations. Ensure measurements are square and level to within millimeters.
4. Log Shell Delivery: Flat-packed kits arrive wrapped on articulated trucks. Confirm site access for large vehicles and arrange on-site offloading equipment (telehandler or mobile crane).
5. Assembly: The pre-cut, numbered timbers are stacked on site by an experienced crew—typically taking 1 to 3 weeks for the structural shell.
6. Settling Setup & Finishing: Install settling hardware (adjustable screw jacks under vertical posts, slip joints around doors/windows) to allow natural timber movement. Complete roof coverings, utility hookups, and interior fit-outs.

Site preparation and foundations

Allow 10–15% of your total budget for preparing the site and building the foundations. This includes excavation, drainage, the concrete base and trenches for utility connections.

Log package and delivery

The log package and delivery account for 35–45% of your total budget. This covers the factory-produced timber kit, windows, doors, roof structure and shipping to your site.

Building the shell

Allow 10–15% of your total budget for the labour needed to assemble the building’s outer shell. This includes constructing the log walls, tiling the roof and sealing the exterior against the weather.

Utilities and services

Heating, ventilation, plumbing and electrical work account for 15–20% of your total budget. This includes systems such as a heat pump and mechanical ventilation with heat recovery (MVHR), along with installing pipes, wiring and final fittings.

Interior finishes

Allow 10–15% of your total budget for completing the interior. This includes the kitchen, bathrooms, flooring and finishing details such as skirting boards and door trims.

Contingency allowance

Set aside 10% of your total budget for unexpected costs, such as unforeseen ground conditions or changes to the design.

These percentages are planning allowances. The final allocation will depend on your project, and the upper limits should not all be added together.

• Initial Sealing (Year 1): Apply a high-quality, breathable UV-resistant timber stain immediately after shell erection to protect wood from moisture and sunlight.
• Re-Staining (Every 3–5 Years): Reapply exterior finish depending on sun and weather exposure.
• Annual Inspections: Check corner interlocking joints for tight seals, clear roof gutters to prevent splashback onto lower log courses, and adjust screw jacks if timber settling occurs.

A square log home uses timbers that are milled flat on all four sides (or flat on top and bottom with smooth outer faces). Unlike round logs, which retain their natural curved tree shape and require deep overlapping saddles, square logs feature engineered tongue-and-groove horizontal channels and precision-cut corner joints (such as dovetail or notch joints). This creates a sleek, flat-walled appearance with exceptional structural stability and draft protection.

Square log homes are exceptionally versatile. While traditional dovetail corners offer a classic rustic charm, modern square profile logs can be milled with flush "City Corners" (no extended log ends), paired with large floor-to-ceiling triple-glazed windows, clean lines, and contemporary finishes. This allows them to blend seamlessly into urban, suburban, or modern eco-development settings.

Flat interior log walls eliminate the decorating challenges of curved timber. Standard kitchen cabinets, wardrobes, headboards, and bathroom vanities mount completely flush against the walls without custom scribing or back-framing. Hanging artwork, installing switch plates, and fitting trim or baseboards is as straightforward as in a conventional home.

Generally, no. Modern square profile logs feature engineered tongue-and-groove profiles with internal gaskets or sealant strips concealed inside the horizontal seams. This creates a weather-tight, draft-proof seal hidden between the timber courses. Visible synthetic chinking is only used if a client specifically requests a traditional North American pioneer aesthetic.

The initial construction costs for log homes are comparable to high-end custom traditional homes. However, overall expenses can vary widely based on whether you choose a kit, a turn-key build, or custom handcrafted logs. Factor in potential higher shipping costs for logs and specialized labour.

Logs have high thermal mass, meaning they absorb heat during the day and release it slowly at night. While wood does not have the same R-value as modern insulation per inch, a properly sealed log home with thick logs performs exceptionally well in keeping interior temperatures stable.

Log homes require regular upkeep to prevent moisture damage and insect infestation:

• Exterior Staining/Sealing: Reapply every 3 to 5 years depending on sun and weather exposure.
• Chinking and Caulking: Inspect annually for gaps or cracks where air or water could enter.
• Gutters and Overhangs: Keep wide roof overhangs and clear gutters to direct rainwater away from logs.

Yes. As logs dry, they shrink slightly, causing the walls to settle—sometimes up to several inches depending on the wood type and moisture content. Professional builders use specialized settling hardware (such as screw jacks, slip joints, and flexible flashing around windows and doors) to accommodate this movement without structural damage.

• Financing: Some traditional lenders are unfamiliar with log home construction and appraisal comparables. Working with lenders who specialize in custom, or log home loans makes the process smoother.
• Insurance: Insurance rates are generally similar to traditional homes, but insurers may require proof of fire prevention measures if the property is located in a rural or wooded area.

Wood-boring insects can be an issue if logs are exposed to moisture. Keeping logs dry, elevated off the ground with a proper foundation, and treated with borate preservatives during construction prevents pest infestations.

• Handcrafted: Logs are hand-peeled and fitted individually, giving a rustic, unique look. Higher labour cost.
• Milled: Logs are machine-cut to uniform shapes and sizes, making assembly faster and more precise.
• Kits/Packages: Pre-cut, numbered logs and materials are delivered to the site for assembly by a builder or knowledgeable owner.

When properly constructed and maintained, log homes can last for centuries. Many log structures in Europe and North America have stood for over 100 to 200 years. Key factors in longevity include a solid foundation, wide roof overhangs to shield logs from rain and UV rays, and routine stain/sealant maintenance.

Surprisingly, thick solid logs often perform better in severe fires than standard wood-built timber framing. Large logs char on the outside, creating an insulating layer that slows down the burning process and helps maintain structural integrity longer than thin 2x4 studs. Standard fire safety measures (detectors, clear perimeter brush) still apply.

• Electrical: Wiring is planned prior to construction. Builders drill vertical channels through the logs during assembly or run wiring through interior partition walls, subfloors, and decorative baseboards.
• Plumbing: Most plumbing is routed through interior stud-framed walls (such as bathroom and kitchen walls) rather than outer log walls to prevent freezing and ease installation.

Yes. Log homes perform well in extreme cold, dry heat, and humid environments. However, design tweaks are required depending on climate:

• Humid/Rainy Climates: Require larger roof overhangs (at least 2 to 3 feet), higher concrete foundations to keep logs away from ground moisture, and frequent sealant checks.
• Cold Climates: Require thicker logs (at least 8–10 inches in diameter) or full chinking for optimal thermal performance.

• Green Logs: Freshly cut logs with high moisture content. They are the least expensive upfront but undergo significant shrinking, checking (cracking), and settling over time.
• Air-Dried Logs: Dried naturally over several months to a year. Moisture is reduced, but some settling will still occur.
• Kiln-Dried Logs: Baked in a heated kiln to drop moisture content below 19%. This minimizes future shrinking, settling, and warping, and kills any existing pests inside the wood, though it carries a higher initial cost.

• Resale: Log homes appeal to a niche market. While they often hold strong value in scenic, rural, or vacation destinations, they may take longer to sell in traditional suburban neighborhoods compared to standard homes.
• Insurance: Rates are generally comparable to custom homes, though insurers may require an inspection verifying proper heating systems and distance to the nearest fire statio

Unlike traditional round logs, square-cut (or square-milled) log homes use timber that has been milled flat on all four sides or milled flat on the top and bottom with smooth outer faces. The corners are precision-cut using interlocking joints—such as dovetail, saddle notch, or lap joints—creating a tight, tight-fitting seal that locks the logs together securely without relying entirely on external fasteners.

Square-cut logs provide exceptional structural stability because the flat top-and-bottom surfaces allow the logs to stack evenly with maximum surface-to-surface contact. This distribution of weight minimizes twisting and lateral movement as the wood seasons and settles compared to round logs.

• Dovetail Joints: The most classic square-log corner connection. Slanted, interlocking trapezoidal cuts funnel water away from the joint and utilize gravity to pull the logs tighter together as the home settles.
• Tipp-Saddle / Notch Joints: Machine-cut notches where intersecting logs drop into overlapping recessed grooves for a tight wind-resistant lock.
• Butt-and-Pass with Splines: Straight square cuts where logs meet at right angles, reinforced with internal alignment keys (splines) and long lag screws.

It depends on the profile:

• Chinked Style: Traditional square timber homes often leave a uniform 1 to 2-inch gap between rows filled with modern synthetic chinking for a classic pioneer look.
• Chinkless / Tongue-and-Groove Profile: Modern milled square logs feature engineered tongue-and-groove patterns on the top and bottom edges. Foam gasket tape or sealant is laid between rows, allowing the logs to interlock tightly without visible chinking lines on the exterior or interior.

Yes. Rainwater tends to pool on the upper curve of round logs if roof overhangs are insufficient. Square-cut logs feature flat exterior faces often milled with a slight drip edge or bevel on the lower corner, which encourages rainwater to shed downward quickly away from horizontal joints.

Square-cut interlocking log packages generally assemble faster on site. Because the logs are milled to uniform heights and pre-cut with precise corner notches at the factory, they fit together like puzzle pieces, significantly reducing the specialized hand-crafting required during construction.

Square profile logs rely heavily on wood's natural thermal mass to regulate indoor temperatures. However, because solid timber typically provides an R-value of around R-1.2 to R-1.4 per inch, meeting strict modern building energy codes (like IECC) can require additional strategy depending on the wall thickness:

• Thick Solid Timber: Solid square profile logs that are 20cm to 30cm thick often satisfy thermal performance standards due to air-tight tongue-and-groove milling combined with thermal mass dynamics.
• Double-Log / Insulated Core Systems: Some square profile manufacturers offer double-wall interlocking profiles (an exterior square log face, an insulated cavity filled with rigid foam or cellulose insulation, and an interior square log face). This creates a high total R-value (R-20 to R-30+) while maintaining a solid timber appearance inside and out.

Square profile walls provide flat vertical surfaces, which simplifies interior decorating:

• Furniture Placement: Cabinets, headboards, and shelving mount flush against the walls without requiring custom-notched backing or scribing.
• Trim and Framing: Hanging picture frames, installing electrical switch covers, and trimming out window frames is much simpler on flat-surfaced timber than on curved logs.
• Modern vs. Rustic Balance: Flat square walls give interiors a clean, contemporary line-work aesthetic that blends easily with drywall partition walls, modern kitchen island setups, and contemporary cabinetry.

Interlocking square log corners utilize precise factory milling to keep water out:

• Internal Drip Edges: Precision-machined grooves direct water down the exterior surface and prevent wind-driven rain from penetrating horizontal seam joints.
• Gasket Tape & Sealer: High-density foam gaskets, expanding memory tape, or specialized mastic sealant are laid inside the corner interlocks during stacking to block air and water drafts.
• Overhanging Roofs: Deep roof overhangs (60cm to 90cm minimum) are engineered above corner joins to keep bulk rainwater away from vulnerable end-grain cuts.

Maintenance routines for square profile homes are generally similar to traditional log structures, but with a few advantages:

• Less Water Pooling: Flat square faces with bevels shed water downward faster than the upper curves of round logs, reducing the risk of water standing on log surfaces.
• Staining Efficiency: The flat, uniform exterior surfaces make power-washing, sanding, and applying exterior oil-based stains easier and quicker than working around curved log profiles.
• Gasket & Corner Audits: Annual inspections focus primarily on checking the precision-cut corners for settling movement or tiny gaps in the sealant.

Yes, square profile interlocking log kits are among the most popular choices for owner-builders and self-builders:

• Pre-Cut Precision: Every log is factory-milled to exact dimensions, pre-notched at the corners, and numbered to match a master assembly layout.
• Stacking Mechanics: Because top and bottom profiles feature interlocking tongue-and-groove alignments, logs align automatically as they are stacked, eliminating manual scribing or hand-notching on site.
• Equipment Needs: While small-to-medium square logs can be lifted manually by a crew of two or three, larger timber packages still require crane or boom-truck assistance to lift long wall logs into place safely.

Across the European Union and the UK, all new residential builds must meet Nearly Zero-Energy Building (NZEB) standards and pass strict Energy Performance Certificate (EPC) ratings.

• Thick Solid Timber: In Northern and Eastern Europe (e.g., Scandinavia, the Baltics), thick solid square logs (200 mm to 270+ mm) are widely accepted because European building codes allow heat-retention calculations (thermal mass) to offset lower raw insulation values.
• Insulated Double-Log Systems: In Central and Western Europe (e.g., Germany, France, the UK) where strict U-value thresholds apply (often requiring wall  -values below  ), builders typically use a double-wall square log profile. This features an exterior timber log, a thick core of natural insulation (such as wood fibre, hemp, or cellulose), and an interior square log face.

European structural design for timber falls under Eurocode 5 (EN 1995), which governs structural integrity, load-bearing capacities, and mechanical connections.

• Logs must carry CE marking (or UKCA marking in Great Britain) under standard EN 14081 to certify structural grading and moisture levels.
• Most European manufacturers source slow-grown Northern European softwoods (such as Finnish Pine or Scandinavian Spruce), which have denser growth rings and provide superior strength against warping.

Yes, for permanent primary residences or holiday lets, full planning permission and building regulation compliance are mandatory across European jurisdictions:

• Planning Permission: Local councils evaluate site impact, local aesthetics, ridge heights, and environmental impact. In historic or protected rural zones (e.g., UK National Parks or French Architectes des Bâtiments de France zones), square profile logs are often preferred over round logs because their clean, linear elevation blends more easily with traditional regional timber or masonry styles.
• Permitted Development / Minor Outbuildings: Small standalone square log garden rooms or annexes under specific size thresholds (e.g., under 2.5 m eaves height or under   floor area in the UK) may fall under permitted development without formal planning, provided they are not used as self-contained residential dwellings.

Yes, Glulam square logs (Leimholz or Lamellipuu) are standard across much of the European log home industry.

• Manufacturing: Multiple kiln-dried timber boards are bonded together under high pressure with weatherproof, low-emission adhesives.
• Benefits: Glulam square logs suffer virtually zero settling, cracking, or twisting compared to solid wood logs. This makes them easier to integrate with strict European triple-glazed window frames, large glass sliding doors, and modern multi-storey architectural layouts.

Fire safety compliance follows European standard EN 13501 (reaction to fire) and Eurocode 5 Part 1-2 (structural fire design).

• Charring Rate: Large-section square timbers burn at a slow, predictable rate (approx. 0.65 mm to 0.7 mm per minute for softwoods). Because of this predictable charring layer, thick square log walls easily meet 30-minute (REI 30) or 60-minute (REI 60) European structural fire resistance requirements without needing extra interior fireproofing drywall.
• Interlocking Sealing: Modern precision-milled tongue-and-groove joints stop flames and hot gases from bleeding through wall seams during a fire.

Because most European suppliers manufacture log kits in Scandinavia, the Baltics, or Central Europe, logistics are optimized for international freight:

• Shipping: Kits are flat-packed onto standard European articulated trucks (curtainsiders or flatbeds) in climate-controlled weatherproof wrapping.
• Site Access: European delivery sites—especially narrow alpine roads or rural country lanes—require advance planning. Transport companies often arrange a transshipment offload onto smaller 4-wheel drive rigid trucks or cranes for the final leg to the building site.

• Solid Timber Logs: Milled from a single piece of slow-grown softwood. They provide pure, natural wood character at a lower upfront material cost, but undergo standard seasoning, minor checking (surface cracks), and natural settling over time.
• Glulam (Glued Laminated) Logs: Engineered by bonding multiple kiln-dried timber slats together under high pressure with non-toxic, weatherproof adhesives. Glulam square logs are significantly stronger, resist twisting, warping, or cracking, and experience virtually zero structural settling—making them the gold standard for multi-storey builds and large open-plan glass designs.

The top and bottom edges of each square log are factory-milled with interlocking ridges and grooves. High-density expansion foam tape or sealant gaskets are laid within these grooves during assembly. When stacked, gravity compresses the joints tightly together. Exterior log faces are also cut with subtle drip bevels, causing rain to shed downward away from horizontal seams.

As solid timber cures, wall height can decrease slightly over the first few years. Precision-engineered log kits incorporate settling hardware to manage this:

• Adjustable Screw Jacks: Placed under vertical load-bearing posts to adjust heights as horizontal logs settle.
• Slip Joints & Sliding Brackets: Installed above windows, doors, and interior frame connections so openings remain completely unaffected by wall movement.

Electrical distribution is planned in advance. During factory CNC milling, vertical channels and junction box cavities are pre-drilled straight through the logs at calculated switch and outlet points. Wiring is pulled through these internal channels as the walls are stacked. Primary plumbing runs are typically routed through interior stud partition walls or under floor voids.

• Chalet Corner (Traditional Cross-Corner): Log ends extend past the corner intersection, creating a classic European alpine or lodge profile.
• City Corner (Modern Flush Corner): Logs terminate flush at the wall edge with a clean corner cover, ideal for contemporary aesthetics, narrow urban plots, or strict planning height boundaries.

Thick timber walls utilize wood's natural thermal mass. Logs store heat during warmer hours and radiate it back inside slowly as temperatures drop, reducing peak heating and cooling loads. While wood has a lower raw R-value per inch than fiberglass insulation, the combination of thermal mass, airtight tongue-and-groove milling, and continuous solid timber walls creates an exceptionally comfortable indoor environment.

For regions requiring ultra-low thermal transmittance ( -values below  ), we offer Insulated Double-Log Wall Systems. This profile consists of an exterior square log face, a high-performance continuous insulation cavity (using wood fiber, mineral wool, or eco-cellulose), and an interior square log face. This satisfies strict modern building control regulations while maintaining real wood surfaces inside and out.

Heavy solid timbers perform exceptionally well in fires—often outperforming thin steel or light timber framing. When exposed to fire, the outer layer of a thick square log chars at a slow, predictable rate (approx.  ). This char layer insulates the inner core of the log, preserving structural load integrity for extended periods and routinely meeting standard European and UK 30- to 60-minute structural fire ratings (REI 30 / REI 60).

• Factory Log Package: Includes precision CNC-cut wall timbers, internal structural posts/beams, roof joists/purlins, factory-painted triple-glazed windows, external doors, and assembly hardware.
• Turnkey Build: Includes the complete factory package PLUS site preparation, foundations, delivery offloading, shell erection, roofing installation, first- and second-fix utilities (plumbing/electrical/heating), and interior fit-out (kitchens, bathrooms, flooring).

Once architectural designs and electrical layout plans are approved, factory CNC production typically takes 4 to 8 weeks. Transport to your site takes 1 to 2 weeks. Once delivered, stacking the pre-cut, numbered log shell on a pre-prepared foundation takes approximately 1 to 3 weeks depending on house size.

Log components are flat-packed, wrapped in weatherproof protective film, and loaded onto standard articulated freight trucks. If your site has narrow access or weight restrictions, we arrange a local transshipment hub where packages are transferred onto smaller 4x4 rigid vehicles or offloaded using specialized telehandlers.

Yes. Because every timber is factory-milled, pre-drilled, and numbered to match detailed assembly drawings, square log kits assemble logically like a precision puzzle. Knowledgeable self-builders with timber-frame experience can stack small-to-medium kits, though hiring a crane or telehandler and employing an experienced timber supervisor for key structural stages is strongly recommended.

Yes. We supply full architectural line drawings, foundation layouts, 3D model renders, structural load calculations (compliant with Eurocode 5), and thermal performance ( -value) documentation required by your local planning authority and building control inspectors.

When built on a solid foundation with wide roof overhangs and proper moisture protection, a square log home can easily last 100 to 200+ years. Historic square log buildings across Scandinavia and Eastern Europe have stood for centuries.

Immediately after shell assembly, an exterior breathable, water-repellent, and UV-blocking timber finish/stain must be applied to shield the wood from sunlight and rain. Depending on weather exposure and stain quality, reapplication is typically required every 3 to 5 years.

Kiln-drying timbers to below 18% moisture content eliminates naturally occurring larvae and deprives insects of the moist environment they require to thrive. Keeping the lowest log course elevated on a proper concrete or stone foundation away from ground soil further protects the structure from pest intrusion.

• Annually: Inspect exterior corner joints and perimeter window caulking for tight seals. Clean roof gutters to prevent rainwater splashback onto lower wall courses.
• Bi-Annually (First 3 Years): Inspect internal adjustable screw jacks (under posts or stairs) and turn them slightly if solid log wall settling has occurred.

All projects are stage paid at specific stages.

The first payment would usually be for 2d & 3d visual design drawings, detailed specifications, supporting information for planning and explanation of materials. This fee would be variable according to each individual project and advised on once we have had the opportunity to scope any proposed project i.e. size, scale, complexity, and structural details.

It is often the case that many proposed projects are at vastly various stages of development and may or may not require detailed drawings at the very early stages and are about getting a general feel for project costs before proceeding any further. 

Prior to ordering a log building a detailed plan and contract will be submitted for signing and approval. At this point a 50% nonrefundable deposit will be required with the remaining balance paid either in stages or in full to ensure the building is 100% paid before leaving production.

Please note: no buildings leave production for transport to their final destination until they are 100% paid, you are always welcome to inspect any buildings before delivery and also use a third-party agent to check should you require. We also photograph all pallets before delivery and also on the transport before leaving and forward to customers so they can see progress and what is happening at distinct stages.

Delivery is very project specific and calculated from a site visit to confirm access and the coordination of unloading pallets of materials. This is usually from truck transport from our specialist logistic partners and on occasions can be from shipping containers. 

All transport solutions are priced on a project-by-project basis and are shown as a separate cost item. Most projects unless they are small log buildings will require a telehandler or forklift to unload pallets which can be 6 metres long and weigh as much as 2500kg. 

All options are looked at in detail to ensure a safe delivery and we all always on site to receive deliveries and ensure all packages are correct and safely positioned ready to build in sequence.

If we have an accurate delivery address, we can give an indicative price for transport and where required transit papers and customs documents. All deliveries have full in transit insurance.

Please note: Transport costs are payable in full prior to any truck or trucks leaving producti

Building works for log assembly and associated works are priced on a project-by-project basis and form a separate contract to the supply and delivery contract. All building works are performed on a fixed cost agreement and payable weekly on larger contracts on a performance related basis. 

All payments for products and services are invoiced individually through our Zero-accounting system and payable as bank-to-bank transfers or through the Stripe payment system.
