Why do credit notes go missing?
Nothing in the process forces them to arrive. Invoices have due dates, dunning runs, and a supplier who wants payment. A credit note has no due date and no chaser. Credits may be issued against a different invoice or account, emailed to a person instead of a monitored inbox, netted into a statement nobody opens, or booked to one group entity while the spend sits in another. With a median AP exception rate of 11–14% of invoices, a document that demands nothing can remain unattended (SSON R&A, 2026).
The AP exception-rate benchmarks show why queues are already overloaded. The audit-input FAQ covers the exports and statements used in a lookback.
Where would missing credits show up?
They usually appear on supplier statements. Manual statement reconciliation is time-consuming enough that most teams cover their top 10–15% of suppliers and leave the remaining 85–90% unchecked (SSON/Xelix, 2026). Credits can sit in that unchecked population as statement lines absent from the ledger. A payment-side control does not see the error because the problem is an absence; it appears only when the full statement is reconciled.
Which industries lose the most to missing credits?
Retail and consumer goods lead at 0.17% of annual spend because volume rebates, promotional allowances, and seasonal pricing agreements generate credits across multiple invoices and accounts. Healthcare follows at 0.14%, while manufacturing loses 0.06% to credits but much more to duplicate payments (SSON/Xelix, 2026). See the full industry leakage benchmark table.
How do you recover missing credit notes?
Reconcile every statement in scope, not a sample. Agents can read statement PDFs, match invoice and credit lines against the ledger across entities, and surface each unapplied credit with the statement line, original invoice, and credit document attached. A read-only lookback across 12–24 months of statements and ledger entries identifies credits that may still be claimable.
Running the same reconciliation continuously in Accounts Payable means new credits can be applied without relying on someone to remember them. The comparison with ledger-based AP controls explains why document and statement coverage changes the result.
