STACK

Takeoff and estimating that works with your ERP – not around it.

STACK connects directly to your ERP so your takeoff data, costs & project details stay in sync – no double entry, no manual exports.

What They Do

Construction teams traditionally work in disconnected tools – takeoffs in one place, estimates in spreadsheets, and financial data living separately in the ERP. That disconnect means manual data entry, copy-paste errors, and finance, PMs, and field teams working from different numbers. STACK eliminates that gap by connecting your takeoff workflow directly to your ERP, so the right data reaches the right people without the rework.

Bid Faster

Complete takeoffs in minutes, not hours! More speed means more bids, and more bids mean more wins.

Win More

Greater accuracy means you can price with confidence, not pad for uncertainty. 

Grow Your Revenue

Streamlined preconstruction delivers time savings, increased win rates and profit protection.

How They Help

Sage handles your financial and project accounting – STACK handles your takeoffs.

The two are stronger together. Once your takeoff or estimate is complete in STACK, the ERP Connector automatically pushes your materials, quantities, and cost data directly into Sage Intacct or Sage 300, no manual exports required.

Budget creation that used to be rebuilt from scratch is now a direct push. Forecasting stays aligned with your estimate. And your whole team – estimators, finance, and ops – works from one verified source of data.

Takeoff and estimating that works with your ERP

STACK works with Alliance Solutions Group partners to help construction organizations unify preconstruction with their ERP. By connecting takeoffs, estimates, materials, quantities, and cost data directly to Sage Intacct and Sage 300, STACK eliminates manual data entry, reduces errors, and gives estimating, finance, and operations teams a single source of truth from bid to budget.
