ChargeMate vs Justt: Which Chargeback Service Is Right for You?
Choosing between ChargeMate and Justt comes down to one core question: do you want a purely AI-driven automation layer, or a service that combines AI with human expertise? Both platforms target merchants who need better chargeback outcomes, but they take fundamentally different approaches. Justt is a fully automated solution that uses machine learning to build and submit dispute responses. ChargeMate offers both a self-serve AI tool and a managed outsourcing service where specialists handle everything. This comparison breaks down pricing, win rates, integration requirements, and the scenarios where each service makes the most sense.
How Each Service Works
Justt operates as a fully automated chargeback mitigation platform. Once connected to your payment processor, it monitors incoming disputes, collects evidence automatically, and submits responses without human involvement. The appeal is speed and hands-off operation — once configured, it runs in the background. However, this automation requires a direct API integration with your processor, and the quality of each response depends on how well Justt's models have been trained on your specific dispute types.
ChargeMate takes a hybrid approach. The AI SaaS tool lets merchants upload evidence documents and generate network-compliant response letters in minutes, with the merchant controlling the final submission. The outsourcing service assigns human dispute specialists who review each case, select the strongest legal ground, prepare evidence, and submit responses on your behalf. This human layer is particularly valuable for complex or high-value disputes where nuance matters.
The key operational difference is control. With Justt, the platform makes decisions autonomously. With ChargeMate's outsourcing, specialists make judgment calls that automation can miss — for example, identifying when a dispute falls under a different reason code than the issuing bank assigned, or when a compelling evidence submission under Visa's CE 3.0 framework is the right strategy.
Pricing Comparison
Justt typically operates on a success-based model, taking a percentage of recovered revenue. Exact pricing is not public but industry reports place it in the 15–25% range of recovered amounts, often with a minimum commitment requirement for high-volume merchants. This model aligns incentives but can become expensive as recovery volumes grow — a merchant recovering $50,000 per month could pay $7,500–12,500 to Justt alone.
ChargeMate offers two transparent pricing options: a flat $10 per case fee (regardless of outcome), or a 20% success fee applied only to recovered amounts. There is no monthly minimum, no setup fee, and no integration requirement. The flat-fee model is particularly cost-effective for merchants with high win rates, since the cost per case stays fixed even when recoveries are large. The success-fee model suits merchants who want to share risk with ChargeMate.
For the self-serve AI tool, ChargeMate includes 3 free responses to start and subscription plans thereafter — a much lower price point than any managed service. If your team has capacity to review and submit responses but just needs help writing them, the AI tool saves significant time without the cost of full outsourcing.
Integration Requirements
Justt requires a technical integration with your payment processor or acquiring bank to pull dispute data automatically. While this integration enables full automation, it creates a dependency on your processor's API quality and adds onboarding time — typically several weeks for a complete setup. Merchants on processors without supported integrations cannot use Justt at all.
ChargeMate works without any API connection. For outsourcing clients, you simply forward dispute notifications — by email, screenshot, or direct dashboard access to your processor — and the team handles the rest. This makes ChargeMate immediately accessible to merchants on any payment processor, including regional acquirers, alternative payment methods, or legacy systems that lack modern API coverage.
The no-integration model also means there is no risk of API downtime affecting your dispute submissions. Dispute deadlines are tight — typically 20 days for Visa and Mastercard — and missing them due to a technical failure can mean an automatic loss. ChargeMate's process-based approach eliminates that dependency.
Win Rates and Evidence Quality
Win rate comparisons between chargeback services are difficult to verify independently, as each company reports its own data. Justt has published win rate figures in the 60–70% range for eligible disputes. These figures typically exclude disputes the platform declines to contest (for example, cases where automation determines the evidence is insufficient).
ChargeMate's managed outsourcing service targets 65–75% win rates across the dispute types it handles. Critically, human specialists can evaluate edge cases and make strategic decisions — for example, choosing to submit a pre-compliance response rather than a full representment in situations where that approach has a higher success probability.
One area where human expertise consistently outperforms pure automation is in identifying the correct dispute strategy for ambiguous cases. When a cardholder claims "goods not received" but actually received a defective product, the correct response differs significantly from a standard non-delivery defense. Automated systems may miss these distinctions; experienced specialists do not.
Which Should You Choose?
Choose Justt if you are a high-volume e-commerce merchant (500+ disputes per month) with a supported processor integration, a tech team that can manage the onboarding, and a dispute mix that is relatively standard. The automation scales well, and the hands-off operation suits operations that want minimal manual involvement.
Choose ChargeMate if you are a small to mid-sized merchant (1–500 disputes per month), you want immediate service with no integration work, you handle disputes across multiple processors, or your cases involve complex fraud patterns or high-value transactions where human judgment adds value. ChargeMate is also the better choice if you want to start immediately without a multi-week technical onboarding.
For merchants unsure where to start, ChargeMate's free consultation lets you review your dispute mix and understand which approach will deliver the best outcome for your specific situation.
