Keep payment status separate from invoice value
Paid and unpaid invoices can both represent recorded purchase costs. A change in payment status should not create a second expense. Review invoice number, supplier and date to preserve one financial record per purchase.
Filter exposure by category and supplier
An unpaid total is more useful when management can identify the categories and suppliers behind it. Use the same date window for the register and its summary. Partial-payment status should not be treated as a bank-verified outstanding balance without payment detail.
Use the report as a review queue
The register supports follow-up on recorded payment exposure and source documents. It is not an automatic bank reconciliation or supplier-statement reconciliation system. Confirm payment evidence before communicating an overdue balance.
