A credit note after payment does not by itself refund the customer. Record the approved credit, review the GST adjustment and separately track whether the amount is refunded or applied to a later invoice. Link every step to the original sale. Otherwise, the company can reduce revenue while leaving an unexplained customer credit or making [...]

A missing supplier GST number is a reason to check the invoice before claiming input tax. Confirm the supplier’s registration and request a valid document containing the required details. A company UEN, a payment receipt or a line labelled “GST” does not automatically establish an entitlement to recover the tax. The purchase and the claim [...]

An InvoiceNow transmission failure should be logged against the original document and investigated with the accounting-solution provider. Preserve the error and acknowledgement history, then verify the final outcome before closing the exception. Sending the same invoice repeatedly without knowing its status can create duplicate records. Emailing a PDF to a customer does not prove that [...]

Accounting software opening balances should be reconciled to the agreed closing position in the old system before the new system is used for routine posting. Keep a dated migration pack and test the supporting schedules, not just the trial balance total. A balanced trial balance can still contain the wrong customer balances, duplicated bank entries [...]

A duplicate expense claim payment needs both an accounting correction and a cash-recovery record. Verify the claim, check which payments actually cleared and agree the next step with the employee. Reversing an expense entry is not evidence that the excess payment has been repaid. Keep the original claim, approvals and bank records so the company [...]

A refundable rental deposit is generally tracked separately from rent expense while the company retains a right to recover it. Keep the lease, payment evidence and a deposit schedule so the balance can be reviewed. The word “deposit” on a transfer reference is not enough: the contract determines whether the amount is refundable, applied to [...]

A duplicate supplier invoice should be checked against the original document and payment records before either entry is reversed. Preserve the history and use an approved correction in the accounting system. Deleting the later-looking entry without checking it may remove the valid transaction, obscure a duplicate payment or leave an incorrect GST claim in the [...]

Payment allocation reconciliation is needed when one customer transfer settles several invoices. Match the bank receipt to the customer’s remittance advice, record the amount allocated to each invoice and investigate the remainder. Recording the entire deposit against the newest invoice can leave old debts apparently overdue and distort the customer’s statement, even though the cash [...]

Singapore's GST InvoiceNow rollout includes an April 2028 phase. Existing businesses should check their own implementation date against current IRAS guidance, rather than assume 2029 is the earliest date. Voluntary and compulsory GST registrations have different entry dates. This guide explains how to prepare the company records and system change. The full roll-out timeline The [...]
