The bookkeeper's month-end checklist for AR-heavy Xero clients

For clients whose revenue comes in as large, multi-invoice payments, month-end lives and dies on accounts receivable. Get the cash applied correctly against the right invoices and the close is calm; leave it half-matched and every report downstream is wrong. This is a working checklist for AR-heavy Xero clients, ordered the way an experienced bookkeeper actually moves through it.

Before you touch a payment

• Confirm all sales invoices for the period are raised and approved, so payments have something to match against.
• Check invoice references and numbering are consistent, because sloppy references are what make matching slow later.
• Pull an aged receivables summary as your starting baseline; you will compare against it at the end.

Apply the cash

This is the heart of the close for these clients. Work through each payment received in the period and apply it against the correct invoices.

• Match each remittance to its bank deposit before allocating, so you know the target total.
• Settle full-payment lines first; they are the fast majority.
• Handle part-payments at their exact amount, leaving remainders outstanding.
• Apply credit notes to their invoices rather than mis-recording the shortfall as a part-payment.
• For runs over 50 invoices, split into batch deposits within the cap and reconcile the bank line across them.

Reconcile the bank

• Reconcile every bank account fully; no statement line left unmatched.
• Investigate any deposit you cannot tie to a remittance before period close, not after.
• Confirm no duplicate payments were recorded, a common artefact of split batches.

Review receivables

With cash applied and the bank reconciled, the aged receivables report becomes meaningful again. Compare it to the baseline you pulled at the start.

• Scan for invoices showing outstanding balances that should be fully paid; these flag mis-applied payments or missed credit notes.
• Review genuinely aged debt and confirm it is being chased or provided for.
• Check that rejected or disputed lines, common on NDIS and supermarket runs, are still visible and owned by someone.

Close and document

• Attach remittance advices to their payments in Xero so the audit trail lives where your accountant will look.
• Lock the period once satisfied, to prevent accidental changes to a closed month.
• Note any recurring pain points, a payer whose format is always messy, a run that always splits awkwardly, for next month.

Where the checklist strains

The step that scales worst as a client grows is applying the cash. Everything else is roughly constant work; matching grows with invoice volume and with the messiness of each payer. If a client's month-end is creeping longer, the growth is almost certainly in that one step, and it is the step most worth streamlining, because it is deterministic work that a person is doing by hand.

The rest of the checklist is judgement and review that genuinely needs you. The matching is not. Moving that one step off the critical path is how AR-heavy clients stay profitable to service as they grow.
