MYOB Acumatica Accounts Receivable: Invoices, Dunning Letters and Getting Paid on Time

Australian businesses are waiting longer to get paid. The Payment Times Reporting Regulator’s January 2026 update found the time it takes a large business to pay 95% of its small business invoices has stretched to 64 days, up from 58. If your customers include big companies, your accounts receivable process is doing more work than it used to, and a spreadsheet of overdue invoices next to your accounting file is not keeping up.

This post covers what MYOB Acumatica accounts receivable actually does: invoicing, statements, dunning letters, overdue charges and credit control, plus the GST timing rules that decide when the tax office gets paid. It is the companion piece to our guide on MYOB Acumatica accounts payable, which covers the other side of the ledger.

What MYOB Acumatica accounts receivable covers

The AR module sits inside the core financials, so an invoice raised from a sales order, a project or a service call lands in the same ledger as everything else. No rekeying between a job system and an accounting file. That matters more than it sounds: 45% of Australian businesses say disconnected systems are limiting their growth, and the gap between “we did the work” and “we invoiced the work” is usually where the disconnection costs real money.

Day to day, the accounts receivable workspace handles invoices and credit memos, applies customer payments against open documents, and keeps an aged receivables view that updates as payments land. Every invoice, statement and reminder sent to a customer is stored against their record, so when someone rings to dispute an invoice, the person answering can see the whole history without asking around.

If you reconcile through bank feeds, payments can be matched as they arrive, which keeps the aged debt report honest. An aged report built from stale data is worse than no report, because people trust it.

Statements, dunning letters and overdue charges

Chasing money is the part of AR most businesses run manually, and it is the part MYOB Acumatica automates best.

• Customer statements. Generated on the schedule you set, formatted for print or emailed as PDF or HTML, with copies kept on the customer record.
• Dunning letters. The platform can prepare dunning letters automatically for past-due accounts, escalating through the message sequence you define. First a gentle nudge, later a firmer letter listing every overdue document.
• Overdue charges. Interest on late payment can be calculated as a percentage or a minimum charge amount, and written off later in full or in part if you choose to waive it.

The discipline this creates is the point. When reminders go out on schedule regardless of how busy the office is, customers learn your invoices do not drift. Our AI practice takes the same idea further, with credit control agents that draft the chasing for a person to approve, but the native scheduling alone is a big step up from chasing from a spreadsheet each month.

Almost every AR mess we see has the same shape: invoicing is fine, chasing is personal. One person knows who was called, what was promised and who is about to hit their limit, and it is all in their head or their inbox. Moving that into the system is not about replacing them. It is about the business still getting paid the week they are on leave.

Credit limits and holds

MYOB Acumatica enforces credit limits at the point of document entry, so the conversation about an over-limit customer happens before the goods ship, not after. You can hold new orders automatically, allow temporary limit increases with the right approval, and see exposure per customer across all their open documents.

For businesses selling on account, this is the difference between credit policy as a document and credit policy as a control. It pairs naturally with the reporting and dashboards side of the platform, where days sales outstanding and aged debt trends can sit on the finance dashboard rather than in a month-end pack nobody reads until week two.

GST, BAS and when the ATO gets paid

Here is the compliance detail that catches growing businesses. GST (Goods and Services Tax) on your sales has to be reported on your Business Activity Statement (BAS), and the accounting method you use decides when. On a cash basis, you account for GST when the customer pays you. On a non-cash (accruals) basis, it is generally attributed when you issue the invoice, whether or not the money has arrived.

Most businesses above $10 million aggregated turnover must use the accruals method. Put that next to the payment times data above and the problem is clear: on accruals, a slow-paying customer can mean remitting GST on an invoice you have not been paid for. Your AR ledger is the thing standing between your BAS and your bank balance. Getting tax codes right on AR documents, and keeping the ledger clean enough that the BAS figures reconcile without adjustment, is a standard part of how we set up MYOB Acumatica for Australian businesses.

When it is worth tightening your AR setup

Plenty of MYOB Acumatica sites go live with AR configured to the minimum: invoices out, payments in, statements maybe. If debtor days are creeping up, if one person is the collections process, or if your BAS preparation involves arguing with the aged debt report, the platform almost certainly has capability you are paying for and not using. Dunning schedules, credit holds and statement cycles are configuration, not customisation, so tightening them is usually a small piece of work.
