The Aggregated Transactions function allows users to submit eligible Cash Sales and Cash Purchases to IRAS via InvoiceNow. These transactions can be originated through Invoice, Purchase Invoice, Receipt Voucher, or Payment Voucher, depending on the user's accounting process.
Note: Cash sales recorded through an Invoice can be submitted as Aggregated Transactions if the customer does not have a UEN or a retrieved Peppol account. An eligible Tax Code must be assigned to the transaction before it can be submitted as an Aggregated Transaction.
