BuildCraft Pro is built around speed for the owner-estimator. Instead of drawing every measurement by hand, you can talk the job through with Kim, your AI voice partner, or upload a blueprint and let the AI produce a detailed, trade-organized estimate in minutes. Then you send a professional proposal, invoice, and manage the schedule — all in the same app, with predictable pricing as your crew grows (seats are a flat $19/mo; Kim + Crew includes 3).
It's intentionally lean: no enterprise modules you'll never use, and a 14-day free trial so you can try a real bid before paying.
STACK has a mature, well-regarded digital takeoff toolset and a following among commercial and larger trade contractors. If your bids live or die on high-volume, detail-heavy manual takeoff, and that's the single most important thing to you, STACK's depth there is a real strength. It's worth a look alongside BuildCraft Pro.
If you're a remodeler, small GC, or specialty trade contractor (electrical, plumbing, HVAC, roofing, painting) and you'd rather get a bid out before dinner than spend the night in takeoff software, BuildCraft Pro is designed for you — AI-first, all-in-one, from $59.99/month.
For solo GCs, remodelers, and specialty trades who want fast AI-assisted estimating plus invoicing, scheduling, and a client portal in one flat-priced tool, yes. STACK is often the better pick for takeoff-heavy commercial work that needs the deepest manual digital-takeoff toolset.
