Sage Intacct Construction is the better fit for growing contractors that run several entities and want a native cloud financial system that connects to the rest of their tech stack, while Foundation suits contractors whose accounting revolves around self-performed labor, payroll, and job cost. Both are strong construction accounting systems, and both are quoted rather than priced publicly, so the decision comes down to what your back office struggles with most.

In our ranking of the best construction accounting software, Sage Intacct Construction rates 4.7 out of 5 and Foundation 4.6. Below is how they compare on the points contractors weigh when choosing between them.

Different starting points

Sage Intacct Construction is built on Sage Intacct, a cloud financial system used across many industries, with construction features layered on: a construction work breakdown structure, job estimates, and AP and AR retainage. Its strengths come from the core platform, especially multi-entity accounting, dimensional reporting, and open APIs.

Foundation is accounting and payroll software built only for contractors. Its design starts from the job: every dollar, hour, and quantity tracked by job, with WIP, over and under billing, and budget-to-actual reports. Payroll is part of the product, not something attached later.

That difference explains most of what follows. Sage Intacct Construction is stronger as a finance platform. Foundation is stronger as a contractor’s operating ledger.

Job costing and WIP reporting

Both systems handle construction job costing well, but they emphasize different things. Foundation tracks cost by dollars, hours, and quantities on each job and produces WIP schedules, over and under billing, and budget-to-actual reports that bonding companies and lenders ask for. Contractors who live by the WIP report tend to like how directly Foundation produces it.

Sage Intacct Construction uses dimensions, which let you tag transactions by job, cost code, entity, division, and other attributes, then report across any of them. That makes it flexible for executives and controllers who want to slice results by region or business line as well as by job. It covers job estimates and retainage on both payables and receivables.

Winner for WIP-focused contractors: Foundation. Its reporting is built around the job cost and WIP questions contractors ask every month. Sage Intacct Construction wins when reporting needs to span several companies or divisions.

Payroll

Payroll is where Foundation stands out. One timecard can cover multiple jobs, localities, rates, and trades, and the system produces certified payroll, EEO, and new hire reports. For a self-performing contractor bidding prevailing wage work, that removes a lot of manual effort. Foundation also offers a full construction payroll service through Payroll4Construction.com for firms that want to outsource processing.

Sage Intacct Construction handles payroll through Sage Intacct Construction Payroll, powered by Struxi, which Sage says simplifies certified payroll reporting in all US states and territories and supports union and non-union payroll needs. It requires the Construction subscription and is enabled through your Sage Intacct account manager.

Winner: Foundation. Payroll is native to the product and central to its design. Sage Intacct now covers certified payroll, but contractors with heavy, complex labor will find Foundation the more natural fit.

Multi-entity and growth

Contractors that grow by adding companies, such as a separate equipment entity, a real estate holding company, or divisions in other states, need consolidation that does not require spreadsheets. Sage Intacct Construction’s multi-entity and multi-currency core is its clearest advantage. Intercompany transactions and consolidated reporting are part of the platform.

Foundation can serve contractors with more than one company, but multi-entity consolidation is not what it is known for.

Winner: Sage Intacct Construction. For a contractor with several entities or plans to acquire, it is the stronger platform.

Deployment and integrations

Sage Intacct Construction is native cloud with automatic updates, so there are no servers to maintain and everyone is on the same version. Its open APIs connect it to other tools, including a Procore integration that matters for general contractors whose project managers run jobs in Procore.

Foundation offers both cloud and on-premise options, which suits contractors that want to keep data on their own servers or move to the cloud on their own schedule. It integrates with estimating and project management software, though buyers should confirm the specific products they use.

Winner: Sage Intacct Construction for cloud delivery and integration flexibility. Foundation wins if you need an on-premise option.

Ease of use

Foundation’s interface is more functional than modern. Accountants who know construction tend to find it logical, but new staff may need more time to get comfortable. Sage Intacct Construction feels like a current cloud application, with dashboards and dimensional reports that executives can use without help from accounting.

Neither system is plug and play. Sage Intacct Construction implementation takes planning, often with a partner, and Foundation also needs setup for cost codes, payroll, and reports.

Winner: Sage Intacct Construction for interface and executive reporting.

Pricing and total cost

Neither vendor publishes pricing. Both quote based on the modules you need and your user count. For Sage Intacct Construction, payroll, project costing, and other modules affect the price, and implementation partners add their own fees. Foundation also prices by modules, so a contractor that adds payroll, mobile time entry, and other features will pay more than one buying core accounting alone.

Ask both vendors for written quotes that cover subscription or license costs, implementation, data conversion, training, and renewal terms for at least three years. Compare the full number, not the first-year subscription.

Winner: no clear winner. Quote both for your exact module list.

Implementation and day-to-day support

Switching accounting systems is a project, not a download. With either product, plan for cost code cleanup, conversion of open jobs and retainage balances, payroll setup, and training for both accounting staff and project managers. The best time to go live is the start of a fiscal year or quarter, so payroll history and tax reporting stay clean.

Sage Intacct Construction is often implemented through partners, which means the quality of your rollout depends heavily on the partner you choose. Ask for references from contractors of your size and trade, and ask who will support you after go-live. Foundation builds software only for contractors, so job cost and certified payroll are the core of its product rather than an industry add-on. In both cases, ask how support requests are handled during month-end close, when delays hurt most.

Winner: depends on your partner. A strong Sage Intacct partner and Foundation’s contractor-only focus can both deliver a good rollout. Check references either way.

Which contractors should pick each

A good way to decide is to name the report your company argues about most. If it is the consolidated financial statement across several companies, or the board package that combines divisions, Sage Intacct Construction is built for that problem. If it is the certified payroll report due every week on a prevailing wage job, or the WIP schedule your surety wants each quarter, Foundation is built for that one.

Specialty contractors that self-perform most of their work, such as electrical, mechanical, and concrete firms, often lean toward Foundation because labor is their largest cost. General contractors that subcontract most of their work, run Procore in the field, and are adding entities as they grow often lean toward Sage Intacct Construction. Run the same sample month through both demos, with a real timecard, a retainage invoice, and a WIP report, and the better fit usually becomes obvious.
