A Smarter Use Tax Flow From Start to Finish

Here’s how CereTax’s P2P software simplifies the use tax process, without adding manual steps or guesswork. From invoice to GL, we keep you accurate, fast, and audit-ready.

Step 1: Connect in Real-Time

CereTax P2P plugs into your purchasing or ERP platform via API or batch upload, returning tax results instantly while giving you room for post-processing accuracy.

Step 2: Calculate and Return

We determine taxability based on usage, location, and vendor type—then send it straight back to your system with all the right codes, rates, and logic intact.

Step 3: Flag Variances

We surface the difference between what the vendor charged and what your team should’ve paid, before it hits AP. No more hunting for errors after the fact.

Step 4: Report, Reconcile, Defend

All results are stored at the transaction level, with reporting and audit trails built in. GLs stay clean. Compliance stays tight. And you stay ahead of every review.

How Can a Company Automate Use Tax Accrual on Vendor Invoices?

A company automates use tax accrual by having a tax engine evaluate every vendor invoice line as it enters accounts payable, before the invoice posts. The engine reads what was bought, where it will be used, and who sold it, then returns one of three answers for each line: the vendor charged the right tax, the vendor charged tax that was not due, or the vendor charged no tax on a taxable purchase and use tax must be accrued.

CereTax P2P does this through an API or batch connection to your purchasing or ERP system, returns the result with the tax code and rate, and records the accrual for the general ledger account you specify. The AP team sees a variance flag on the invoice instead of a spreadsheet at month end.

Every decision is stored at the transaction level with the rule that produced it, so an auditor can trace an accrual back to the invoice line. One Fortune 500 manufacturer using CereTax eliminated $1.5 million in vendor overpayments in a year and cut its use tax compliance cost by 80%.
