Does AccuBuild publish a public API?
No. AccuBuild, the on-premise construction accounting system, publishes no public API documentation — there is no API section on the vendor help site and no open developer portal. The one live integration on record is a Procore marketplace listing, which uses OAuth and requires AccuBuild 10.2+ Cloud; that is a specific vendor-to-vendor connection, not an open interface that other software can build against.
What does that mean for expense automation?
Without published API documentation, no card or expense platform can offer a supported direct sync into AccuBuild. Card transactions reach the system the way they do in most on-premise construction packages: keyed in manually against jobs and cost codes, or brought in as a file import in a layout AccuBuild accepts.
Manual entry is the default and the pain point. Charges land on a statement weeks after the spend, the office chases field staff for receipts, and every line has to be coded to a job, phase, and cost code before it can be entered. On a job-cost system, uncoded card spend is spend you cannot see on the job report.
How does Vergo work with AccuBuild?
Vergo makes the file path work like automation. Cardholders code each charge in Vergo at the point of spend — job, cost code, receipt photographed from the field. Vergo then produces a custom-built CSV export matched to the import format AccuBuild expects, so the accounting team loads a coded batch instead of rekeying a month of card activity or reworking a bank export in a spreadsheet.
Vergo does not claim an API sync with AccuBuild, because AccuBuild does not publish one for anyone to use. What Vergo provides is the working path: coding captured once, in the field, and a ready import file at month end.
Could AccuBuild open an API later?
The Procore listing shows AccuBuild can connect when it chooses to build a specific integration, but nothing is publicly documented for third parties today. Teams planning card and expense tooling around AccuBuild should treat file-based integration as the dependable path and revisit if AccuBuild publishes developer documentation.
Does AccuBuild have a public API?
No public API documentation exists — the vendor help site has no API section. The only live integration on record is a Procore marketplace listing, which is not open to third parties.
Doesn't the Procore integration prove an API exists?
It proves AccuBuild built one specific connection (OAuth, requiring AccuBuild 10.2+ Cloud). It does not give other software a documented interface to build against, so expense platforms cannot use it.
How does Vergo get card transactions into AccuBuild?
Cardholders code charges to jobs and cost codes in Vergo with receipts attached, and Vergo generates a custom CSV export matched to AccuBuild's import format for the accounting team to load.
Is the import reviewable before it hits the ledger?
Yes. Nothing enters AccuBuild until the accounting team imports the batch, and approvals happen in Vergo before the export is generated.
