Foundation Software does more construction accounting natively than QuickBooks Enterprise Contractor edition — retainage, certified payroll and AIA-style progress billing are built in, where Enterprise handles two of the three through manual items and an Excel export. Enterprise wins on job-costing depth for its price class, the integration ecosystem, and a cost that most contractors under $25M find easier to justify. Below is the comparison feature by feature, verified only against Foundation’s and Intuit’s own documentation.
Foundation is a construction ERP. Its accounts receivable module is marketed as AIA billing software, its payroll module is built around prevailing-wage and Davis-Bacon work, and its general ledger posts over/under billings (WIP) directly, including the effect of change orders. QuickBooks Enterprise Contractor is a general-purpose accounting system with the strongest job costing in the QuickBooks range bolted on: a Job Costing Center, committed-costs-by-job and work-in-progress reports, change-order handling and flexible billing rates. Where Enterprise falls short of Foundation is retainage and certified payroll, both of which work but through workarounds Intuit documents rather than native modules.
If you run union or prevailing-wage payroll every week across many jobs and bill on AIA-style applications, Foundation’s native depth is real and you should weigh it. If your pain is cost, mobility or integrations, Enterprise Contractor plus one or two construction apps covers most contractors, which is why the Foundation to QuickBooks conversion is one of the routes we run most often.
| Capability | Foundation Software | QuickBooks Enterprise Contractor |
|---|---|---|
| Job costing | Native; budgets by custom cost codes or CSI divisions; compares estimated vs actual revenue, cost, labor hours and quantities | Native; Job Costing Center, job costs by job, committed costs by job, expenses-not-assigned-to-jobs report |
| WIP / over-under billings | Native; viewed and posted from the GL, including change-order impact | Work-in-progress report in Contractor edition; the journal entry is yours to post |
| Retainage receivable | Native; A/R aging and retainage by job, customer and PM | Manual: a Retention item on the invoice and a Retentions Receivable report |
| Retainage payable | Native; entered with the invoice or set aside on the subcontract | Manual, via items and a liability account |
| Certified payroll | Native module; prevailing wage, Davis-Bacon and union payroll | Excel-based Certified Payroll Report on Enhanced or Assisted Desktop Payroll; needs a full Excel install |
| Progress billing | Native, marketed as AIA billing software | Progress invoicing from an estimate, once switched on in preferences |
| Equipment costing | Add-on module; usage by job, cost code and cost type, plus depreciation | Via items, classes or sub-customers; no equipment module |
| Users | Not published | Up to 40 (sold in 1–10, 20, 30, 40 seat bands) |
| Deployment | FOUNDATION Hosted (cloud-hosted desktop) | Local install or cloud hosting powered by Rightworks |
| Published pricing | None — “we don’t offer you standard pricing” | Quoted by Intuit by tier and seats |
Two rows deserve a note. Neither vendor’s product pages state that the software prints the AIA G-702/G-703 forms themselves; Foundation markets “AIA billing software” features and Intuit does not mention the forms at all, so if those exact documents matter to a general contractor, confirm it in a demo rather than assuming. And Foundation’s pricing page says plainly that it does not publish standard pricing, so any dollar figure you read for Foundation is a third-party estimate. We show illustrative ranges on our conversion page and flag them as such.
Intuit calls Enterprise Contractor “the most robust job costing of any QuickBooks product,” and the report set backs that up: committed costs by job (open purchase orders against budget), a WIP report, job costs by job, change-order tracking, flexible billing rates by employee or item, and a report that catches expenses nobody coded to a job. That last one is the report a controller runs before every WIP meeting, and its absence in QuickBooks Online is one reason Desktop remains the default recommendation for contractors.
Foundation goes further in structure rather than in reports. Budgets break down by cost code or CSI division and compare estimated against actual on revenue, cost, hours and quantities — unit productivity, not just dollars. If your PMs manage by units installed per crew-day, that column is the difference. Most contractors under $25M manage by dollars and hours, and Enterprise covers that.
Foundation tracks retainage receivable and payable as first-class data: A/R aging and retainage by job, customer and PM on the receivable side, and retainage entered with the invoice or set aside on the subcontract on the payable side. In QuickBooks Enterprise, Intuit’s own instructions are to put a Retention item on the invoice and review a Retentions Receivable report to see what each customer still owes. It works, and thousands of contractors run it, but it is a discipline rather than a module: someone must add the item every time, and payable retainage needs the mirror-image setup on bills.
When we convert Foundation files, retainage balances are the part we rebuild most carefully, because the open retainage on a half-finished job has to land in a dedicated account at the cutover date or the first post-conversion aging report is wrong. Our Foundation conversion page walks through how that is protected.
Foundation’s payroll module is built for prevailing-wage, Davis-Bacon and union payroll with automatic calculations. In QuickBooks Desktop, certified payroll reports exist — Intuit’s help article (updated August 2026) covers setting up prevailing wages and generating the report — but the report is produced through the “More Payroll Reports in Excel” path and requires a full version of Microsoft Excel. A common misconception is that this needs the Diamond tier; Intuit tags the article for both Enhanced and Assisted Desktop Payroll, so Gold-tier Enhanced Payroll qualifies. The real caveat is workflow: it is an export, not an in-product report, and a contractor filing certified payroll on ten jobs a week will feel that.
Integrations and reach. Project-management and field tools tend to integrate more deeply with QuickBooks than with a construction ERP, and Enterprise supports up to 40 users. Tiering is also a genuine lever: Gold bundles Enhanced Payroll, Platinum adds Advanced Inventory, Advanced Pricing, intercompany transactions and bill/PO approval workflows, and Diamond adds Assisted Payroll and QuickBooks Time Elite on a monthly plan. Availability is not in question either: Intuit’s stop-sell help article, updated August 2026, states that Enterprise “isn’t affected” and can still be purchased new.
For a contractor with one to fifteen employees, no certified payroll and simple job tracking, QuickBooks Online Plus or Advanced can be the right target. Projects handles income and cost by job on both tiers, Advanced adds project estimates, and progress invoicing is native. Check the caps first: Plus allows 5 billable users, a 250-account chart of accounts and 40 combined classes and locations; Advanced lifts all three (25 users, unlimited accounts, classes and locations). A Foundation file with cost codes mapped as accounts will exhaust the 250-account cap on day one, so that mapping decision is made before the migration, not after. Our Desktop vs Online comparison covers the rest of the trade-off.
Stay on Foundation if weekly certified payroll across many jobs, native retainage on both sides, and unit-based productivity budgeting are things your office uses every week, and the contract cost is one you have priced against the alternative. Move to QuickBooks Enterprise Contractor if your team mainly needs strong job costing, WIP and committed-cost reporting, integration with field tools, and a cost you can quote from Intuit by seat count, and you can live with retainage as an item and certified payroll as an Excel export. Our Foundation conversions start at $3,500 fixed-price and typically run six to eight weeks; the Foundation to QuickBooks page has the scope and the scoping-call link.
Not as a module. Intuit's documented method is to add a Retention item to the invoice and track what customers still owe on the Retentions Receivable report; retainage payable is set up the same way on bills. Foundation tracks retainage receivable and payable as native fields with aging by job, customer and PM.
Yes, on Enhanced or Assisted Desktop Payroll. The Certified Payroll Report is generated through More Payroll Reports in Excel and requires a full version of Microsoft Excel. It is not restricted to the Diamond tier.
Yes. Intuit's stop-sell help article, updated August 2026, states that Enterprise is not affected by the September 30, 2024 stop-sell of Pro Plus, Premier Plus and Mac Plus, and that new Enterprise subscriptions can still be purchased.
Often, for one to fifteen employees with simple job tracking and no certified payroll. Projects covers job-level income and cost on Plus and Advanced, but Plus caps the chart of accounts at 250 and combined classes and locations at 40, so a cost-code-heavy Foundation file usually maps to Advanced or to Enterprise.
