Supplier invoices can arrive through email, portals, shared folders and individual members of staff. The bookkeeping challenge is not merely capturing the document; it is knowing whether the invoice is accepted for processing under the client's own approval arrangements and keeping that evidence connected to the payment record. A simple approval trail reduces uncertainty without turning the bookkeeper into the commercial decision-maker.
Capture the invoice before approval status
Record the supplier, invoice reference, date, value and client entity from the source document. Treat those details as separate from approval. An invoice being present in the bookkeeping file does not by itself show that the client has checked the goods, service, price or commercial terms.
Define what approval means for the client
Different clients may have different responsibilities for reviewing supplier invoices. Agree who can approve, how approval is communicated and what should happen when the usual approver is unavailable. The bookkeeping workflow should reflect the client's actual process rather than assuming that a forwarded email or uploaded document automatically carries authority.
Link approval to the exact invoice
An approval message should identify the invoice clearly enough to avoid ambiguity. Supplier name alone may be insufficient where several invoices are outstanding. Connect the approval to the invoice reference or another unambiguous identifier and preserve the evidence in a location the bookkeeping team can retrieve later.
Keep queries distinct from approvals
A response such as “please check this amount” or “I need to ask the supplier” is not an approval. Give disputed or unclear invoices an exception status so they do not drift into the payment-ready queue. The bookkeeping team can track the question while leaving the commercial resolution with the client and supplier.
Control replacement and corrected invoices
If a supplier issues a corrected document, identify which earlier version it replaces and check whether the existing approval still applies under the client's process. Do not leave two active versions with the same apparent status. Retain enough history to show the change while making the current document obvious to the person processing it.
Separate approval from payment evidence
An approved invoice may still be unpaid, while a bank payment may cover several invoices. Keep approval status and payment matching as connected but distinct controls. When payment appears, reconcile it to the relevant supplier account and invoices using the available references rather than assuming that approval means payment has occurred.
Make aged unresolved approvals visible
Invoices waiting for client action can become hidden if the only reminder is an old email. A short exception list can show what is awaiting approval, what is under query and who is expected to respond. Review it at an agreed interval and remove items only when the status genuinely changes.
Close with a traceable chain
The completed record should let a reviewer move from supplier invoice to approval evidence and, where applicable, to the eventual payment allocation. Any unresolved dispute or missing approval should remain visible rather than being disguised by a convenient status. This gives the bookkeeping practice a defensible operational trail while preserving the client's responsibility for authorising its own expenditure.
