STACK review
Bottom line
STACK is a cloud platform that connects plan organization, takeoff, estimating, and field management for construction teams. Its clearest strength is how much of the plan-handling work it automates, from naming and classifying sheets to flagging revisions and linking callouts. The main cost to watch is the $299 monthly starting price, since there is no free plan and only a free trial. It fits estimating teams and contractors who bid from large plan sets and want their takeoffs tied to accounting and project systems.
What is STACK?
STACK is a cloud-based construction software platform that covers preconstruction and field work in one workspace. It addresses the time lost to sorting plan sets, measuring drawings by hand, and keeping estimates current when design revisions arrive. Estimators, project managers, and field crews work from the same drawings, quantities, and budgets.
Day to day, teams upload plans and specifications, and STACK automatically names and numbers each plan page. Its AI sorts drawings into discipline folders such as architectural, civil, and electrical, and it hyperlinks detail callouts to the referenced sheet. Users search by keyword, specification section, or section number across an entire plan set. Takeoff tools measure linear, area, count, and volume quantities, with AI auto-counting symbols. Those quantities flow into a live estimate built from items and assemblies, and Version Compare overlays drawing revisions so changes stand out. After award, the Field App lets crews mark up plans, create daily reports, and track punch lists.
STACK serves specialty contractors, general contractors, suppliers and manufacturers, and owners and developers. Its typical customers range from freelancers and small businesses to mid-size companies and enterprises. Pricing starts at $299 per month, and a free trial is available, though there is no free plan. Viewer seats are unlimited, so people who only review plans or estimates do not add licensing cost.
STACK stands out for its integration reach. STACK for Excel connects takeoff and estimating data directly to spreadsheets, and ERP connectors link estimates to Acumatica, Sage Intacct, Sage 300, and QuickBooks. It also syncs with Procore drawings and plan rooms, and it offers an API. Regional material and labor cost data sits inside the item library, so estimators price items without leaving the takeoff.
