Chargebacks
18 min read
On this page
A chargeback is when a customer's bank forcibly reverses your transaction. You lose the money, pay a fee ($15-100), and it counts against your chargeback ratio.
Your processor might call it a "dispute" (Stripe, Square) or a "chargeback" (traditional processors). Card networks use "dispute." This site uses "chargeback" for consistency, but they mean the same thing: the customer's bank reversed a charge on your account.
Pick Your Mode
You're in danger of hitting network thresholds. Stop reading and go to Reduce Chargebacks Fast. That playbook is designed for the next 72 hours.
- Pull your last 20 disputes and classify by actual cause (fraud vs. friendly fraud vs. merchant error)
- Call 2 customers who disputed. Ask what actually happened.
- Set a simple rule: fight everything over $100, skip everything under $25. Test if that's worth the effort over 30 days.
That's it. Optimization can wait.
Under $100K/month: Your processor's default fraud tools are probably fine. Focus on clear descriptors and easy refunds. Don't buy a chargeback prevention vendor yet.
$100K-$1M/month: Alert services (Ethoca, Verifi CDRN) start making sense. They cost ~$20-40 per alert but prevent the $25-100 chargeback fee and ratio hit.
Over $1M/month: You need a representment strategy. Either build internal capability or hire a vendor. Alert services are mandatory.
Over $10M/month: You probably need a dedicated person for disputes. Consider guaranteed chargeback solutions for high-risk segments, but read the contract carefully.
These are the numbers that matter. Exceed them and you're in a monitoring program with monthly fines.
- 2.2% + 1,500 combined fraud reports + disputes: Merchant Excessive (tightening to 1.5% in April 2026)
- VAMP ratio includes TC40 fraud reports + TC15 chargebacks
- 1.5% + 100/mo: ECM
- 3.0% + 300/mo: HECM
Every chargeback has a reason code. The code determines what evidence you need to fight it.
Feedback Loop: Talk to Your Customers
Before you optimize your representment process, talk to 5 customers who disputed.
Questions to ask (fact-seeking, not opinion-seeking):
- "What were you trying to do when you made this purchase?"
- "What did you expect to see on your statement?"
- "What did you do when you first noticed the problem?"
- "Walk me through what happened after that."
5 conversations will teach you more than 5 hours of dashboard analysis. You'll learn whether you have a representment problem or a root cause problem.
You can fight back. It's called representment. Win rates vary by reason code:
- Fraud (10.4, 4837): 10-25% without 3DS, 50-70% with 3DS authentication
- Not received (13.1): 60-80% with tracking/delivery confirmation
- Cancelled recurring (13.2): 20-40% depending on cancellation proof
- Digital goods: 20-35% with proper evidence collection (see CE 3.0)
For a month, add delivery photos to 50% of "goods not received" response packets. Track win rate difference. If no improvement, stop doing it.
Should I Fight This Chargeback?
This decision tree focuses on reason code (what the customer claims). For the dollar-amount decision, see Refund Strategy. For 3DS liability considerations, see Representment.
Use this decision tree to quickly determine the best action for each dispute.
For dollar-amount thresholds and worked examples by ticket size, see the Refund Strategy triage grid.
Prevention beats representment. Every prevented chargeback saves the fee, the operational cost, and keeps your ratio clean.

| Action | Visa | Mastercard | Amex |
|---|---|---|---|
| Representment | 30 days | 45 days | 20 days |
| Pre-arbitration | 30 days | 30 days | 45 days |

MATCH/TMF: The Blacklist (what gets you permanently banned from processing)
MATCH (Member Alert to Control High-Risk Merchants) is Mastercard's database of terminated merchants. Visa has TMF (Terminated Merchant File). Getting on either makes it extremely difficult to get payment processing.
How You Get Listed
| Reason Code | Description |
|---|---|
| 01 | Account data compromise |
| 02 | Common Point of Purchase (fraud ring) |
| 03 | Laundering |

| 05 | Excessive fraud |
| 06 | Coercion |
| 09 | Bankruptcy/liquidation/insolvency |
What Being Listed Means
- 5 years on the list (most cases)
- No processor will onboard you (they check MATCH before approval)
- Your principals are listed too (owners, 25%+ shareholders)
- Follows you to new businesses (name matching)
Excessive chargebacks or fraud today can make you unemployable in payments for 5 years. Prevention is the only real solution.
