STACK Construction Estimating Software
Bid with Confidence and Connect Your Estimates with Your ERP with STACK
STACK Construction Technologies is a cloud-based takeoff and estimating platform built for contractors, subcontractors, and suppliers. This modern construction management software gives your estimating teams a single system to organize plans, measure drawings and price bids from anywhere, on any device — replacing manual takeoffs and disconnected spreadsheets with a faster, more accurate path from plan to proposal. When paired with your Sage or Acumatica ERP through SWK Technologies, STACK closes the loop between the bid you win and the job you build, syncing finalized estimates, cost codes, and project data directly into your accounting system so your finance and operations teams start every job with accurate numbers.
Beyond speeding up individual takeoffs, STACK is built to keep an entire estimating department working from the same information. Multiple estimators can collaborate on a bid at once, drawing revisions are tracked automatically, and pricing stays consistent through shared item, assembly, and regional cost catalogs. Estimate data is pushed directly into Sage 100 Contractor, Sage Intacct Construction, Acumatica Construction or QuickBooks Online once a bid is won, removing the double entry that often slows down your project set up — so budgets, purchasing and job costing are ready to go the moment a job starts.
STACK Features
Takeoff & Estimate
STACK’s preconstruction suite lets estimators measure drawings, build assemblies, and price bids without leaving the platform. AI-assisted takeoff tools speed up quantity measurement, while a built-in material and cost catalog keeps pricing consistent across every estimator on your team. Key capabilities include:
- AI-powered digital takeoffs with automatic quantity extraction
- Advanced trade-specific measurement tools
- Custom items, assemblies, and regional pricing catalogs
- Version compare to track drawing revisions across bid rounds
- STACK for Excel for estimating directly against synced takeoff data
- Multi-user collaboration on a single estimate in real time
Security & Reliability
STACK is built on a cloud infrastructure designed to keep project and financial data available and protected as it moves between preconstruction and your ERP. Key capabilities include:
- Cloud-based access with no local server dependency
- Role-based permissions across estimating, field, and admin users
- Automated data backup
- Real-time system status monitoring
Plan & Document Management
STACK centralizes every plan and specification in one searchable hub, so estimators start each bid from the most current drawing set instead of hunting through email threads or shared folders. Advanced search surfaces the right sheet or spec section in seconds, while automatic organization keeps large sets of files structured without manual filing. Multiple team members can review and mark up the same set of documents at once, keeping the entire preconstruction group aligned before a single measurement is taken. Key capabilities include:
- Auto plan organization that structures large document sets without manual sorting
- Advanced plan search to locate a sheet or spec section by keyword
Team collaboration on shared drawings, with markups visible to every reviewer
STACK ERP Integrations
Acumatica Construction Edition
STACK connects directly to Acumatica Cloud ERP via API, giving contractors a real-time bridge between preconstruction and financials. Cost estimates flow into your accounting system as jobs are awarded, keeping budgets current and giving project managers and your accounting team a shared, up-to-date view of every build. The integration also supports both on-demand and continuous syncing, so your teams are not limited to a fixed schedule or dependent on separate import and export files to move data between platforms.
Sage Intacct Construction
STACK’s integration with Sage Intacct syncs project and estimate data in real time, letting your team import projects from the accounting system into STACK and export finalized bids back as budgets. Cost codes, job details and other records are able to be synced directly into your financial management platform — removing the manual re-entry that typically slows down setup and keeping your preconstruction and financial teams aligned from bid to build. Available through the Sage Intacct Marketplace, the connection also lets contractors create a new STACK job straight from an existing Construction record and push a completed proposal back as a line-item cost estimate without leaving either system.
