Where the vendor descriptions differ
- AI role: Bobyard says it is trained on millions of drawings and that each supported trade has its own trade-specific takeoff model; for landscaping and paving maintenance, aerial takeoffs can start from just an address using aerial imagery. STACK describes AI that reads uploaded sheets, auto-names pages and flags revisions, auto-counts symbols, suggests scope that may be missed, and pressure-tests pricing by flagging risk, gaps and pricing drift in estimates.
- Trades and buyers: Bobyard's FAQ says that as of Q4 2026 it supports six trades (landscaping, electrical, plumbing, mechanical, interior finishes and paving), each with its own page. STACK lists specialty contractors, general contractors, suppliers and manufacturers, and owners and developers.
- Scope beyond takeoff: STACK also covers estimating and proposals and a field and project management product (Build & Operate), with unlimited viewer seats, and its homepage announces STACK for Excel, an integration launched with partner Velixo that connects takeoff and estimating data in Excel. The Bobyard pages we read describe takeoff and estimating only.
- Pricing (checked Oct 19, 2026): Bobyard publishes no prices; its site has no pricing link, /pricing and /plans return a not-found page, and the call to action is "Book a demo". STACK lists Takeoff & Estimate from $299 per user per month, Build & Operate from $49 and the full platform from $348 (shown as "as low as"), a free version of Takeoff & Estimate and a two-week free trial of Build & Operate.
- Vendor claims (not verified): Bobyard's customer quote cites 5X bid volume; its FAQ's takeoff time-reduction range is not used here. Neither tool has been tested by Means & Methods Lab, and takeoff accuracy was not compared.
Paraphrased from the sources listed above. Vendor claims are reported as claims.
What we can't tell you yet
Which tool is better for your work. That needs testing on the same package with a verified answer key. Planned measures for this comparison:
- Takeoff accuracy for each trade on the same drawing set, and how much estimator correction each needs
- How each handles heavy civil or sitework drawings outside the trades it lists
- Outside Means & Methods Lab's current benchmark scope.
