If chargebacks are cutting into your margin, the fastest fix isn't a better refund policy — it's making sure every disputed charge gets a complete, on-time evidence file instead of a rushed one or a missed deadline. That's the job these tools automate. For most Shopify and Stripe sellers, Chargeflow is the strongest starting point: it charges only when it recovers money, so there's no upfront cost to test it. Larger merchants doing real volume get more from Justt, and stores that want chargeback defense bundled with broader fraud screening should look at Kount. Here's how the leading options actually compare.

Quick comparison

1. Chargeflow — best for Shopify and Stripe stores

Chargeflow's pitch is full automation: it pulls order, shipping, and customer-communication data directly from your Shopify, Stripe, PayPal, Braintree, or Klarna integration, builds a representment evidence packet, and files it with the card network before your deadline — no manual form-filling. It advertises an average win rate in the 70s, which is a vendor claim worth verifying against your own results rather than taking at face value, and it's SOC 2 Type II certified, which matters if you're handling customer payment data at any real volume. Try Chargeflow.

Pricing runs on a success fee — one widely cited figure is around 25% of recovered chargeback amounts, with no flat monthly minimum on its standard plan — so a store that never wins a dispute pays nothing. The trade-off some reviewers note: it's strongest on the evidence-filing side and weaker on pre-dispute alerts that might stop a chargeback before it's even filed.

Pros: no upfront cost since you only pay on recovered funds; broad native integrations with the platforms most sellers already use; built specifically around automated evidence generation. Cons: success-fee percentages can add up at high dispute volume compared to a flat-rate tool; pre-dispute alerting is reportedly a weaker part of the product than representment itself.

2. Justt — best for high-volume merchants

Justt targets a different tier of merchant: it's generally positioned as the better fit once you're doing meaningful card volume, with sources citing roughly $10M+ in annual transactions as the range where its enterprise-grade evidence process pays off. It supports a wide range of payment service providers — one third-party comparison cites more than 40 — which matters if your store runs multiple processors across regions. Try Justt.

Like Chargeflow, Justt charges a success fee rather than a flat subscription, so there's no platform cost if a dispute isn't won. One independent comparison flagged that its percentage-of-recovered-funds pricing can end up costing more than a flat-rate competitor at very high volume, which is worth modeling against your own typical dispute size before committing.

Pros: built for scale, with support for a wide range of payment processors; no flat platform fee regardless of volume. Cons: the sweet spot is clearly larger merchants — a small store is unlikely to see the same value; percentage-based pricing needs modeling against your actual numbers to confirm it beats a flat-fee alternative.

3. Kount — best for fraud screening plus chargeback defense

Kount, now part of Equifax, is less a single-purpose chargeback tool and more a fraud-prevention platform that folds chargeback and dispute defense into a broader risk-scoring suite. For a store that's already dealing with both fraudulent orders at checkout and the resulting disputes after the fact, that combination means one vendor relationship instead of two separate subscriptions. Learn about Kount.

Kount doesn't publish self-serve pricing — it's a quote-based enterprise platform, which puts it out of reach for a store just starting to deal with chargebacks but makes sense for a merchant already budgeting for fraud infrastructure.

Pros: combines pre-transaction fraud scoring with post-transaction dispute handling in one platform; backed by Equifax's broader identity and risk data. Cons: no published pricing, and the sales-led process is slower than signing up for a success-fee tool directly; likely overkill and overpriced for a small store whose chargeback volume is still low.

4. Zendesk — best if disputes already live in your help desk

If your team is already fielding chargeback-related customer conversations inside a help desk, moving dispute handling into a separate dedicated tool adds a system to check rather than removing work. Zendesk's AI features can help draft and route responses to dispute-related tickets inside the same inbox agents already use for order and return questions, which keeps the paper trail in one place. Try Zendesk.

Zendesk starts at roughly $19/agent/month for its core plan, with AI features layered into higher tiers — notably cheaper to start than a dedicated chargeback platform, but it isn't purpose-built for representment evidence the way Chargeflow or Justt are, so you're trading automation depth for consolidation.

Pros: keeps dispute communication inside the support system your team already uses daily; lower entry price than dedicated chargeback platforms. Cons: not purpose-built for chargeback evidence filing, so you'll likely still assemble the actual representment packet by hand; AI drafting helps with communication, not the dispute-winning paperwork itself.

How to choose

• You're a Shopify or Stripe store testing whether automation is worth it: start with Chargeflow — you pay nothing unless it recovers money.
• You're doing serious volume across multiple processors: Justt is built for that scale.
• You want chargeback defense bundled with fraud prevention at checkout: Kount, if you're ready for a quote-based enterprise platform.
• Your disputes are still low-volume and already flow through support tickets: stick with Zendesk rather than adding a new subscription yet.

Whichever tool you pick, remember that published win rates are vendor claims, not audited figures — results depend heavily on your processor, your order documentation, and the type of dispute.
