Everything builders ask about running project accounting on Stak — QuickBooks integration, cost-plus billing, change orders, AI, security, and pricing.
Most builders are live in under an hour. Stak connects to your existing accounting software, so there is no migration or rip-and-replace — you keep working the way you do today, with Stak layered on top.
See how Stak compares to QuickBooks alone →Stak is built for construction — custom-home builders, remodelers, and general contractors who run cost-plus or budgeted projects and need clean client bills, job costing, and change-order tracking. It was designed by people who felt the pain of billing clients on a real build.
Yes — keep both. Stak does not replace your accounting system or your accountant; it supercharges the project-accounting side (invoices, job costs, client bills, change orders) and syncs the results back to QuickBooks.
Yes. Stak integrates with both QuickBooks Desktop and QuickBooks Online. Invoices and project data you process in Stak sync back into QuickBooks, so your books stay the single source of truth.
Stak for QuickBooks users →QuickBooks handles your books; Stak handles construction project accounting on top of it. Out of the box you add budget-to-actuals reports with change orders isolated, change-order tracking with e-signatures, AI invoice extraction and cost-code categorization, per-project markup, duplicate-invoice detection, and client-ready bills — none of which QuickBooks does on its own.
QuickBooks alone vs. with Stak →Stak is built around QuickBooks Desktop and QuickBooks Online today. If you are on a different system, schedule a demo and we will talk through your setup.
Yes. The QuickBooks sync is two-way — Stak reads from and writes back to QuickBooks — and every sync is controlled by you: you decide what data moves. Stak never shares sensitive personal financial information such as credit card numbers, bank account details, or Social Security numbers. Your QuickBooks books stay the single source of truth.
How Stak syncs with QuickBooks →Stak keeps budgets, job costs, and change orders organized per project, then produces clear client bills that separate budgeted work from change orders. Markups and taxes are calculated for you, and every line ties back to its source invoice — so cost-plus billing is transparent and fast.
How cost-plus billing works in Stak →Create a change order in Stak and send it straight to your client for a legally binding digital signature through Dropbox Sign. Approvals come back in minutes, not days, and the change order stays isolated from budgeted work on every invoice and budget-to-actuals report.
Yes. Stak client bill reports show progress, billed-to-date, and a projected final cost, and close with a complete record of work — each budgeted and change-order item tied to its vendor, source invoice, and amount. Clients get a transparent, auditable account of exactly what was done.
It is a real-time view of project profitability by cost code — what you budgeted versus what you have actually spent, with change orders isolated so overages are obvious. Spot problems early instead of at the end of the job.
Yes. Snap a photo of a receipt or vendor invoice and text it to Stak. The AI reads it on the spot; reply with the project number and it is filed in seconds. No app to open, no manual entry.
Bruce is the AI engine inside Stak. He drafts client and vendor emails, builds reports that surface project insights, and predicts costs before they surprise you — and every draft is fully editable, so you stay in control.
Stak pairs AI predictions with human oversight — the Validate step — so extracted invoice data and cost-code assignments are checked before they hit your books. You get the speed of automation with the control of a review.
Stak processes your documents through established providers and applies reasonable technical and organizational safeguards. Our Privacy Policy details exactly what we collect, how it is processed, and your rights.

Stak delivers complete financial visibility at about a third of the cost of comparable construction accounting software. For pricing tailored to how many projects you run, schedule a quick demo.
