Vendor Statement Reconciliation

Vendor statement reconciliation compares a vendor's own statement, invoices billed, payments received, credits issued, against what your AP subledger shows for that same vendor. The statement comes from outside your books, so it catches what your own ledger has no way to flag on its own: a bill that never arrived, a credit nobody applied, a payment the vendor logged against the wrong invoice.

Three-way match and a GRNI accrual both work inside your own records, an invoice you already have, checked against a PO and a receipt you already have. Vendor statement reconciliation starts from a document you didn't generate, which makes it the one process built to catch an invoice that never reached AP at all: lost in a mailbox, sent to the wrong address, never mailed.

Comparing the two lists line by line turns up three kinds of difference. A missing invoice is one the vendor's statement shows and your subledger doesn't, because it never reached AP, got misfiled, or arrived and was never keyed; until it's recorded, the liability sits off your books, understated. An unapplied credit is one the vendor's statement carries, a return, a rebate, an overpayment refund, that your subledger has never applied against a balance; the vendor agrees you're owed, and nobody's claimed it. A disputed item is the same invoice at two different amounts, or a payment the vendor hasn't matched to the right bill, a difference someone has to call and resolve rather than a rule.

All three get named, classified, and aged the way any reconciling item does on a bank reconciliation or a balance sheet reconciliation. A missing invoice still open after three statements running means your AP process stopped keeping up with that vendor, not that the vendor forgot to bill you.

This doesn't run against every vendor every period. Volume makes that impractical, so it concentrates on the vendors with the largest exposure, high transaction count, high dollar volume, a history of disputes, run on a standing schedule rather than triggered after a problem turns up somewhere else.

Pulling a vendor's statement and matching it against the subledger, vendor by vendor, scales with how many vendors you have, not with how much judgment any one line needs. Adopt's agents pull the statement, match it against the subledger per vendor, and return a discrepancy list with a proposed action on each line: missing invoice flagged for entry, credit flagged for application, dispute routed to a person with both figures attached.
