A past due invoice is an invoice that has not been paid by its due date.
Once the payment due date passes and a balance remains unpaid, that balance is considered past due.
For a small business owner, past due invoices represent customer payments that were expected by a certain date but have not yet been received.
When Does an Invoice Become Past Due?
An invoice becomes past due after its stated payment due date has passed.
For example, suppose you send a customer a $1,000 invoice due on November 15.
If the customer has not paid the invoice by the end of November 15, the unpaid balance becomes past due after that date.
The amount remains past due until the customer pays it or the balance is otherwise adjusted.
What Is the Difference Between an Outstanding Invoice and a Past Due Invoice?
An outstanding invoice has an unpaid balance.
A past due invoice has an unpaid balance and has also passed its payment due date.
For example, an invoice due in 30 days is outstanding while the business is waiting for payment during that 30-day period.
If the due date passes and the balance remains unpaid, the invoice becomes past due.
This distinction helps separate customer payments that are still within their expected payment period from those that have gone beyond it.
Can Part of an Invoice Be Past Due?
Yes.
If a customer makes a partial payment, the remaining unpaid balance can become past due once the due date passes.
Suppose a customer owes $2,000 and pays $1,500 before the due date.
If the remaining $500 is still unpaid after the due date, that $500 becomes past due.
The past due amount reflects the portion of the invoice that remains unpaid.
How Long Can an Invoice Remain Past Due?
An invoice can remain past due until the unpaid balance is resolved.
That may happen when the customer pays the balance, the business applies a credit or adjustment, or the invoice is otherwise updated.
As long as an unpaid amount remains after the due date, that amount continues to be past due.
Why Is the Due Date Important?
The due date establishes when the business expects to receive payment.
Without a due date, it can be harder to determine whether a customer payment is still within the expected payment period or has become late.
A clear due date also makes it easier to identify which invoices need attention as customer balances remain unpaid.
How Business Cash Manager Tracks Past Due Customer Payments
Business Cash Manager allows you to record expected customer payments and the dates you expect to receive them.
When an expected payment date passes and the payment has not been received, the amount can remain visible as past due.
This keeps overdue customer payments connected to the rest of your cash information so you can see which expected cash has not yet arrived.
