Seljax

What Seljax does

Seljax is a privately held Canadian software company founded in 1994 by Braven Blackwell that develops estimating and 3D design software purpose-built for retail lumber dealers and building material suppliers. Headquartered in Spruce Grove, Alberta, with operations spanning Canada and the United States, the company has operated continuously for over 30 years as a fully bootstrapped, founder-led business with no disclosed institutional funding.

The platform consists of five integrated products — 3D House, 3D Deck, 3D Stud Frame, 3D Post Frame, and 3D Deck Online — that convert uploaded project plans into complete, build-ready material lists paired with synchronized 3D visualizations. The underlying technology combines 3D design rendering, takeoff and estimating automation, and direct point-of-sale integration with Epicor, ECI, DMSI, and Acceo systems, eliminating double data entry and enabling automatic pricing updates from the POS to the estimate.

Seljax monetizes through annual SaaS subscriptions on a quote-based, custom-priced model. Go-to-market is primarily enterprise field sales with a demo-centric conversion path, supplemented by an embedded product-led growth channel via the 3D Deck Online lead generator. The customer base consists of hundreds of SMB retail lumber dealers and building supply businesses across North America, supported through direct demos, on-site training, and association memberships in Supply Build Canada, BLD Connection, BMSA, AQMAT, and WBMA.

Core offering

Seljax provides web-based 3D design and takeoff/estimating software built specifically for retail lumberyards. The platform converts building plans into 3D models, automatically generates complete build-ready material lists, and integrates directly with point-of-sale systems for seamless quote-to-order processing across houses, decks, stud frames, and post-frame buildings.

Product overview

Seljax is a unified estimating and 3D design platform built specifically for retail lumberyards. The platform consists of five integrated products: 3D House for residential and commercial building estimates from PDF plans; 3D Deck for deck designs and material lists; 3D Stud Frame for garage and workshop framing; 3D Post Frame for agricultural and commercial post-frame structures; and 3D Deck Online as a customer-facing lead generation tool. All products share a common workflow where 3D designs and material takeoffs are synchronized, with direct connections to point-of-sale systems for seamless quote-to-order processing.

Scale indicators6 records

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• Procore Technologies: Procore is the leading construction management platform serving general contractors and owners. While not a direct competitor to Seljax's lumberyard estimating tool, Procore's expansive ecosystem and capital resources position it as a potential adjacent competitor or strategic acquirer in the construction software space.

Emerging players

• Foundation Software: Foundation Software provides accounting and project management solutions for specialty contractors including concrete, masonry, and mechanical trades. It is comparable as a vertical software vendor serving specific construction industry niches similar to Seljax's lumberyard vertical approach.
• Buildertrend: Buildertrend is a construction project management platform for residential builders and remodelers. It serves an adjacent customer base (builders rather than lumberyards) but overlaps in residential construction workflow software, making it a partial competitor for contractor-facing estimating tools.

Direct peers

• On-Screen Takeoff (On Center Software): On-Screen Takeoff is an established takeoff software product widely used in commercial construction. It competes with Seljax in the digital takeoff and estimating category, though it targets larger commercial projects versus Seljax's lumberyard-vertical focus.
• STACK Construction Technologies: STACK is a cloud-based takeoff and estimating platform serving general contractors and specialty trades. It competes with Seljax for construction estimating workloads and offers similar pre-construction software-as-a-service capabilities, though without Seljax's lumberyard-vertical depth.
• PlanSwift (now part of ConstructConnect): PlanSwift is a takeoff and estimating software for construction professionals covering multiple trades. Seljax explicitly names PlanSwift as a direct competitor, though Seljax differentiates through vertical specialization for lumber dealers versus PlanSwift's broader construction focus.
• Bluebeam (Nemetschek Group): Bluebeam Revu is a widely-used PDF-based takeoff, markup, and estimating tool for the AEC industry. Seljax names Bluebeam as a direct competitor in its blog content, though Bluebeam targets general contractors and design professionals rather than retail lumber dealers specifically.

Others

• ECI Software Solutions: ECI provides business management software for lumber, building materials, and hardware retailers through products like Spruce and PowerHouse. As a Seljax POS integration partner, ECI serves the same customer base and could expand into estimating functionality.
• Epicor (Lumber/Building Materials ERP): Epicor is a major ERP and POS software provider with a dedicated Lumber and Building Materials industry solution. Seljax integrates directly with Epicor POS, making Epicor a key channel partner rather than direct competitor. Epicor could potentially develop competing estimating functionality.
• DMSI (Dealer Management Systems Inc.): DMSI provides management software for lumber and building material dealers. As a POS integration partner with Seljax, DMSI serves an overlapping customer base in the Canadian and US lumber dealer market, functioning as a complementary technology partner.
