Prop Firm Merchant Account Declined? The Chargeback Problem

Quick answer: Prop firms get declined, reserved, or cut off for the same reason a lot of high-risk verticals do: the dispute ratio, not the product. A trader pays a challenge fee, fails the evaluation, and instead of accepting the loss, disputes the charge with their card issuer, sometimes claiming the product wasn't as described, sometimes just hoping the bank sides with them by default. Multiply that across enough failed challenges and the ratio climbs into territory that gets a merchant account flagged, reserved against, or terminated, regardless of how legitimate the business is. A settlement setup with no chargeback ratio to defend removes that specific failure mode: challenge fees still clear by card, but a disputed charge months later doesn't reopen anything or move a number anyone is tracking.

If your processor just declined a new application, moved you to a reserve, or cut you off after a run of disputes, here's the mechanism behind it and what a different settlement structure looks like.

Why do prop firms get flagged for chargebacks specifically?

A challenge fee is a strange transaction from a card network's point of view. The trader pays upfront for a shot at a payout, and most of the time, they don't get the payout, because most challenges fail. That's the business model working exactly as designed, but it also means a large share of your customers walk away from every transaction having "lost." Some of them accept that. A meaningful number don't, and a dispute with their bank costs them nothing to try and can, if it works, get their money back on a fee they earned in full when the challenge started.

What does a failed-challenge dispute actually look like?

The trader contacts their card issuer, not the firm, and disputes the original charge. Common framings are "the service wasn't provided" (despite having received the full challenge and every rule that governed it), "I didn't authorize this" on a card they used seconds earlier, or a straightforward request to reverse a fee they now regret paying. Card networks call this friendly fraud when there's no actual unauthorized use, but the dispute still counts against the merchant's ratio the same as a stolen-card chargeback would. The firm loses the revenue, pays a chargeback fee that typically runs $15 to $25 per dispute on top of the lost fee, and can still owe an affiliate commission on a sale that just got reversed.

Why is this worse for prop firms than for most other high-risk verticals?

Volume and rejection rate compound against each other. A retail merchant selling a product has a healthy majority of satisfied buyers and a small dispute tail. A prop firm's core product is an evaluation that's built to be failed by most people who attempt it, which means the population most likely to feel cheated, and therefore most likely to dispute, is also the larger group. It isn't a flaw in any individual firm's operation. It's built into what a challenge-fee model is.

What happens once the dispute ratio climbs?

Visa's Acquirer Monitoring Program set an "excessive" dispute-ratio threshold at 1.5% starting April 1, 2026, with an $8 fee on every disputed or fraudulent card-not-present transaction once a merchant crosses it, and Mastercard runs a comparable program that can flag an account at as few as 100 disputes and a 1.5% ratio. Cross either threshold and the standard response from a processor is a bigger reserve, tighter volume limits, or non-renewal of the account, not a review of whether the underlying challenges were run fairly. A firm can have a clean track record on every other metric and still get flagged purely on dispute volume from a customer base that's designed to mostly lose.

Doesn't a strict no-chargeback policy in the terms of service fix this?

It helps at the margin but doesn't remove the exposure. Most reliable prop firms now prohibit chargebacks outright in their terms, precisely because the pattern is common enough to write a policy around. The problem is that a terms-of-service clause doesn't stop a trader from filing a dispute with their bank; it only gives the firm grounds to fight it after the fact. Winning a dispute still takes documentation, still takes time, and still leaves the disputed transaction sitting in the ratio while it's contested. The policy reduces losses. It doesn't touch the ratio math a processor is watching.

How does settlement work without a chargeback ratio to defend?

ePayVista isn't a card-network merchant account, so there's no dispute ratio sitting between a challenge-fee charge and your money. Traders still pay by card exactly like today, entering a challenge the same way they always have. What changes is what happens once that charge clears: funds move over our managed, non-custodial settlement layer, our rails, directly into an account only the firm controls. Settled means settled, so a trader who fails a challenge and disputes the fee three months later doesn't reopen the transaction or move a ratio anywhere. Setup is a WooCommerce plugin install and connecting that account, live in about 5 minutes, flat 1%, no reserve.

FAQ

The ratio is the actual product risk

A challenge-fee business will always generate more disputes than a business selling something most customers walk away satisfied with, because the model is built around a majority who don't get what they paid to try for. Terms-of-service language and dispute-fighting reduce the damage. They don't remove the ratio a processor is watching, or the reserve and re-underwriting risk that comes with crossing it. The setup that removes the exposure entirely is the one with no ratio sitting between a disputed challenge fee and money that's already settled.

Get on the ePayVista waitlist or install the WooCommerce plugin and start collecting challenge fees without a dispute ratio to defend, flat 1%, settled into an account only your firm controls.
