Accounts payable: What remains owed, and why?

From invoice to settlement

A bank debit without a supplier document may be a missing-invoice exception; it is not automatically a payable settlement.

Worked example

A synthetic firm receives a €2,000.00 invoice, pays €1,200.00, and later receives a valid €300.00 correction. The open balance is:

€2,000.00 - €1,200.00 - €300.00 = €500.00

The €500.00 remains payable unless another documented event resolves it. Closing the invoice because the supplier name appears on the bank would conceal the residual.

Whether the invoice and correction are recognised in a particular period requires professional review.

From source documents to the €500 residual

The useful monthly case contains four connected records: the original €2,000 invoice, the €1,200 bank debit, the €300 credit note referring to the invoice, and the €500 remaining supplier balance. DeinHans can prepare the supplier identity, document relationship, payment candidate and arithmetic, then leave the residual visibly open for review. It does not create or authorize a supplier payment.

This is why a payable list is not a payment proposal. It explains what appears to remain owed and why.

What owners should monitor

• invoices nearing due date;
• invoices recorded twice;
• payments without allocation;
• part payments and disputed amounts;
• credits not connected to the original invoice;
• supplier identity or bank-detail changes;
• old balances with no recent activity;
• amounts paid privately or through another entity.

Responsibility boundary

The owner confirms purchase, business purpose, delivery, dispute, and payment facts. Software can group the supplier history and calculate open balances. The accountant reviews the liability, account, tax, and period treatment.

DeinHans can keep each payable attached to evidence and bank context, prepare matching candidates, and carry unresolved balances into the month handoff. It is not an accounts-payable approval or payment-run system: it does not initiate payments, approve bank details, or decide whether an invoice should be paid. It should not hide a residual merely to make the supplier balance appear reconciled.

Month-end handoff

Provide an open-payables list with source links, due dates, allocations, disputes, and corrections. Highlight old or unusual balances. The reviewer then sees both the payable total and the evidence that explains it.

Ageing without false certainty

An ageing report is useful only if due dates and allocations are reliable. Split the list into not due, overdue, disputed, missing evidence and credit balance. A negative supplier balance may be an unapplied credit, duplicate payment or refund receivable; it should not be reclassified automatically. Compare material or high-volume vendors with supplier statements and investigate differences invoice by invoice.

For each old balance, record the last evidence check and next action. “Over 90 days” is not an accounting conclusion. It may reflect a genuine dispute, a payment from another account, a credit not received or a stale import. Any write-off, release or reclassification needs the appropriate professional decision.

Controls before a payment run

Before authorizing payment, verify the current invoice, supplier identity, bank details, approval authority, open balance and duplicate-payment history. Changed bank details should be confirmed through an independent channel. Keep payment authorization separate from bookkeeping preparation where staffing makes that practical.

After the run, link every bank movement to the approved items and reconcile rejected or returned payments. This closes the loop between liability, authorization and cash rather than treating the bank file as proof that every invoice was valid.

Reviewer record

For material suppliers, retain opening balance, invoices, credits, allocated payments and closing balance with a statement date. Highlight transactions posted directly to the supplier control account and balances transferred between supplier identities. Ask the reviewer to approve the explanation, not merely the total.

If a supplier confirms a different balance, reconcile document by document and note timing items on both sides. A statement can itself be incomplete; it is corroborating evidence, not an automatic replacement for the business’s invoice history.
