A credit or negative customer balance often means QuickBooks shows more credit than unpaid invoices for that customer.
The customer may have overpaid. A credit memo or payment may also be waiting to be applied.
Check the records before you refund money or change the balance.
Why can a customer have a negative balance?
Common reasons include:
- the customer paid too much;
- a payment was entered twice;
- a credit memo has not been used;
- a payment was not linked to an invoice;
- a refund was not recorded in the expected way;
- an invoice was changed or removed after payment;
- QuickBooks applied a credit to a different invoice.
A negative balance is a reason to review the customer’s records. It does not tell you the full cause by itself.
What should I check?
Review the customer record and compare:
- open invoices;
- payments received;
- credit memos;
- refunds;
- payment dates;
- invoice dates;
- amounts still open;
- any recent changes.
Also check whether QuickBooks is set to apply credits on its own.
What if the customer overpaid?
QuickBooks can keep the extra amount as a credit. The credit may be used on another invoice or refunded to the customer.
First confirm the payment and the amount that should have been paid.
Do not refund a credit only because the balance is negative. Make sure the records support the refund.
What if the credit has not been applied?
An unused payment or credit memo may stay open until it is linked to an invoice.
This can make the customer record show both an open invoice and a credit at the same time.
Check that the invoice and credit belong to the same customer and should be linked before changing anything.
Does a customer credit represent recoverable value?
No.
A customer credit may be money owed to the customer, an unused payment, a record error, or a valid credit for future work.
It is not recoverable value for RecurSave merely because it appears in QuickBooks.
Why can this become hard to check?
One credit may be easy to trace.
A full year may contain many invoices, payments, refunds, and credit memos. One payment may cover several invoices. Credits may also be used later.
A negative balance alone does not prove what should happen next.
