Why was my merchant account terminated?

Terminations rarely come with a full explanation. The acquirer's letter usually cites "risk" or "breach of terms" and leaves you to work out the rest. In practice, almost every termination falls into one of the categories below.

1. Chargeback ratio

The most common cause. Once you exceed roughly 0.9–1% of transactions (the exact thresholds differ between Visa and Mastercard programmes), the acquirer starts paying fines on your behalf. Most will warn once, sometimes not at all.

2. Undisclosed change in business

New products, a new website, a new country of customers, a jump in average ticket. Anything the underwriter did not approve is, from the acquirer's side, a different business processing on your account.

3. Volume outside the approved range

Both directions matter. Exceeding your monthly cap is obvious. Processing far below projections can also trigger a review, because it suggests the account is being used differently than described.

4. Fraud or card testing

A burst of small authorisations from many cards is card testing. If your checkout has no velocity controls, the acquirer will often close the account before you notice.

5. Aggregator policy changes

Stripe, PayPal, Square and similar platforms adjust their prohibited-business lists regularly. Merchants in categories that were tolerated last year are removed this year, frequently with funds held for 90–180 days.

6. Transaction laundering or multiple accounts

Processing for another business, or spreading volume across accounts to hide ratios, is detected more often than merchants expect and results in immediate termination and a MATCH listing.

7. Acquirer portfolio exit

Sometimes it is not about you. Acquirers exit categories or regions and close every account in them.

What to do in the first 48 hours

• Ask, in writing, for the termination reason and whether you have been listed on MATCH.
• Request your reserve release schedule and final settlement statement.
• Export every processing statement and chargeback report you can still access.
• Do not open a new aggregator account with the same details and the same problems — that is how a second termination happens.
• Get an honest assessment of what an underwriter will now see before applying anywhere.

KLAUDE reviews terminated merchants regularly. Many can be placed again; the ones that cannot are told so quickly, without wasted applications.
