Accounts receivable fraud often starts quietly. A payment gets posted to the customer. An old invoice stays open a little long. Then someone notices that the numbers don’t quite fit. Everyone is already busy closing the month.

Where the Trouble Usually Starts

The weak spot is often the process, not one employee. If one person can create a customer change an invoice record a payment and approve a credit note there isn’t much standing between a mistake and a deliberate scheme.

Fraud doesn’t always look dramatic. A fake customer account can sit there for months. A payment can be moved from one account to another to hide a balance. A credit memo can quietly erase a debt. The amounts may be small at first which is why people stop noticing them.

Watch the Odd Patterns

Your accounts receivable reports already contain clues. You just need to look at them

• Payments that keep getting moved especially when the same accounts show up again and again.

• A customer balance suddenly drops after an adjustment but nobody seems quite sure why it happened.

• Credit notes with explanations. “Pricing issue” isn’t much of an explanation when the amount is large.

• Old invoices that keep changing status or due dates which gets suspicious when the changes cluster around month-end.

• New customer accounts with details. A real customer usually leaves a trail beyond one created record.

Don’t Rely on Trust Alone

Honestly this is where many companies get uncomfortable. They trust employees, especially the ones who’ve been around for years. That’s understandable. It’s also a control.

Good controls aren’t accusations. They’re guardrails. Separate the person who creates or edits customer records from the person who approves adjustments. Require approval for credit notes. Keep a record of who changed what and when.

Prevention Needs Some Friction

The trick is to make suspicious activity harder to hide without making normal work miserable. Automated approval rules work well here because they don’t depend on someone remembering every time.

Set limits for manual write-offs. Review changes before month-end close. Reconcile customer balances against bank activity on a schedule.. Keep access tight. If someone doesn’t need permission to edit receivables they shouldn’t have it.

Look Beyond the Final Number

A clean accounts balance doesn’t prove that everything is clean. The useful question is how the number got there.

Review the adjustments behind changes. Check activity, around reporting dates. Pay attention when one customer account behaves differently from the rest.
