Procore says one number. Accounting says another. Somebody's spreadsheet splits the difference.

On paper the systems already connect. Procore has a Sage connector. Vista has an API. Somebody demoed all of this during implementation and it worked on the test job.

Then the cost codes drifted. A job got set up with a slightly different structure because the owner required a different breakdown. A PM added a code on the fly to track something the budget did not anticipate. A commitment got written in Procore that does not tie cleanly to the subcontract in accounting. None of that is anyone's fault, and all of it is normal. Six months later the sync produces numbers that are close but not equal, nobody can explain the delta in the time they have, and everyone quietly goes back to Excel.

So the reconciliation happens by hand. Someone pulls committed cost from one system, actuals from another, and the schedule of values from the spreadsheet that has become the real system of record for that job. They line it up, they find the variance, and they make a judgment call about which number to trust. Then they do it again next week.

A $30M contractor and a $300M contractor both need an estimator, a controller, a G&A policy, and a project management stack. One of them spreads that cost across ten times the volume. The overhead is not proportional to the work, and the reconciliation hours are the part of it nobody budgeted for.

Revelry reads across all of it as it sits. Procore comes in through Procore Analytics, the data share Procore sells alongside it. Bid history comes from BuildingConnected through Autodesk. Accounting comes in as an export, on whatever cadence your controller already runs. Documents and the spreadsheets that actually run your jobs get read where they live.

Nothing migrates. Procore stays Procore. Your ERP stays your ERP. The field learns nothing new. Revelry reads and produces. Where a connected system can be written to at all, the write is held for a person to approve and the decision is logged, because nothing should be posting to your books on the strength of a demo.
