Amex P03: credit processed as charge
P03 means the Card Member says a transaction that should have been a refund was processed as a charge. It’s a processing error, and the fix is usually fast: show the charge was right, or show the offsetting credit.
What P03 means
P03 means a refund went the wrong direction. The Card Member says the transaction you submitted as a charge should have been a credit. Amex’s guide lists four causes:
- A credit the customer expected was never issued.
- A credit was keyed as a debit by mistake.
- A credit was issued but didn’t post before the customer’s statement.
- A sale that should have been voided was processed instead.
What the customer told Amex
“I was supposed to get money back, and instead they charged me.” Often it’s a front-desk keying error, and both sides know it.
Time limit
Processor guides list this code at 120 days from the transaction date, in line with Amex’s general 120-day window for Card Members (Amex’s word for cardholders).
Your side of the clock is short. Amex’s own guide tells merchants to respond within 20 days. If you accept Amex through a processor such as Stripe or Square, the processor sets its own date, often a shorter one. The due date on your notice is the one that counts.
What proof matters
Amex accepts proof that the charge was submitted correctly, or proof that a credit directly offsetting it has already been processed. If it really was an error, the second answer is the honest one.
A keyed refund can cost you double
When a refund is keyed as a sale, the customer doesn’t just miss their refund. They get charged the amount on top. That’s why P03 disputes tend to be confident and quick. Catch these in your daily batch review: a “sale” that matches the amount of a return you discussed with a customer is a red flag.
Amex’s prevention advice for P03: make sure each amount you submit is correctly a debit or a credit, process corrections as soon as you spot or hear about an error, issue credits within 7 calendar days, and state your refund time frames clearly.
The common mistake
Fixing it with a fresh refund after the dispute has already arrived, without telling anyone. Show Amex the correcting credit so you don’t refund twice.
