Unmatched central receipts: a common in-house bank failure

A common failure is a customer payment that the central entity collects but cannot tie to a subsidiary. It sits in a suspense account. The subsidiary keeps chasing a customer who has already paid. Its in-house balance looks too low, and interest is charged on the wrong figure.

How it starts

Centralised collection works well when every payment arrives with a clean reference. Many do not. A customer pays several invoices in one transfer and quotes none of them. Another pays the old legal entity name after a restructuring. A third sends money to the group account but quotes the purchase order number from its own system.

The treasury team posting the receipt has a choice. It can credit a subsidiary on a best guess, or it can park the money. Parking feels safer, so the amount goes to an unallocated receipts account on the in-house bank ledger. The intention is always to come back to it.

The trouble is that nobody owns that account in practice. Treasury assumes the subsidiary will claim the cash when its customer complains. The subsidiary has no view of the suspense balance and does not know the money exists. Meanwhile the external bank account is reconciled perfectly, because the cash really did arrive. Every control that looks at the outside world says the process is fine.

A second route into the same mess is the returned payment. A cheque bounces or a direct debit is recalled. The central entity reverses it on the external side, but the reversal never reaches the subsidiary's in-house account. Now the subsidiary shows cash it does not have.

How it is spotted

The first signal rarely comes from treasury. It comes from a credit controller at the subsidiary who calls a customer about an overdue invoice and hears that it was paid weeks ago, with a remittance to prove it.

Other signals are quieter. The suspense account on the in-house bank ledger grows steadily and is explained only with the word "timing". Intercompany balances between the central entity and a subsidiary refuse to agree at period end. Each side has posted its own view, and the difference is waved through as a reconciling item. Subsidiaries start asking why their in-house statement shows a lower balance than their own cash forecast. Some complain that they were charged overdraft interest in a month when they believe they were in credit.

Auditors sometimes find it before anyone else does. They ask for the ageing of unallocated receipts, and the oldest items predate the people now running the team.

How it is fixed

Clearing the backlog comes first, and it is mostly detective work. Each parked item needs the payer name, the external bank reference and any remittance the customer can resend. Sending the open item list to subsidiary credit teams usually resolves a large share quickly, because they recognise their own customers. Items that still cannot be placed should be returned to the payer or treated under the group's policy for unidentified cash. They should not be left to age.

Once an item is placed, the correction has to land in several places. The subsidiary's in-house account is credited with the original value date, not the date of discovery. Interest for the affected periods is recalculated, and the difference is booked as an adjustment. The subsidiary's receivables ledger is cleared against the right invoices. If a period has already closed, the adjustment goes through a journal with proper approval. Quietly reopening the period is not an acceptable shortcut.

The lasting fix is ownership. Someone in treasury must be named as responsible for the suspense balance, with a target that it is reviewed and worked at every close. Subsidiaries need read access to unallocated items so they can claim their own. Matching rules in the receipt process should be widened to recognise old entity names, purchase order references and known payer accounts. Returned payments need a defined path that reverses the in-house credit at the same moment as the external one.

It also helps to change what customers see. Invoices from every subsidiary should carry a reference format that the central matching routine can read, and the remittance address should be the same across the group.

Questions to ask the people who run it

What really happens to a receipt that cannot be matched on the day it arrives? Who is expected to look at it next, and how would they know?

Can a subsidiary see money sitting in suspense that probably belongs to it?

When a payment comes back unpaid, which ledgers get reversed and in what order? Has anyone ever found a reversal that reached the bank side only?

When an old receipt is finally placed, is interest recalculated, or is the credit simply posted with today's value date?

How are intercompany differences with the in-house bank explained at close? Who signs off on the explanation?

Are there any workarounds, spreadsheets or side agreements with particular subsidiaries that the written procedure does not mention?

The answers to the last question usually reveal where the documented process and the real one parted ways.
