Off your desk

Guzco handles the dispute. Your team handles the customer.

Klarna, PayPal and credit card disputes come in. Guzco contests them, gathers the evidence and submits the response. Your support team does not open the ticket, does not write the email, does not chase the carrier.

Disputes never reach your team

Every Klarna, PayPal and credit card dispute is intercepted, contested and submitted by Guzco before it lands in your support inbox. No portal logins, no copy-paste, no analyst time.

Before Guzco, we lost half our disputes by default and it cost our team hours every day. Now we win nearly all of them, without anyone having to touch them.

Most of our disputes went uncontested simply because nobody had time to chase the order history and the delivery proof. Now Guzco assembles all of that and contests them automatically, so we win back cases we used to write off.

Stephan WassinkCustomer Care Manager

The faster we grew, the faster this problem grew with us. More orders meant more chargebacks and disputes, and it scaled quicker than the team could keep up with. Guzco handles the disputes for us now, so it no longer grows with our revenue.

Frequently asked

Answers before the demo.

What finance and ops leads ask us most often, in plain language.

Once you're integrated, every new dispute is pulled into Guzco automatically. We assemble the evidence, submit the response, and write the outcome back. Your support inbox stays empty. You can review or pause specific cases in the Guzco dashboard, but no manual work is required to keep things running.

Klarna, PayPal, Mastercard, Visa and other major BNPL providers. We connect via API where available and via portal automation where it is not. New providers are added without setup work on your side. If you use a provider not yet listed, ask us; we add the most-requested ones first.

Most merchants are live within two weeks. Week one we connect and pull historical dispute data so we can calibrate. Week two we run in shadow mode, where you can compare what Guzco would do against what your team did. Week three we go live. No code changes on your side; the integrations are at the provider level.

Customer data is processed to assemble dispute evidence, nothing else. We are GDPR compliant, host in the EU, and sign a Data Processing Agreement with every merchant. Data is not sold, not used to train models for other companies, and is deleted on request. The full list of sub-processors is available on https://trust.guzco.ai/

Our team monitors policy and evidence-format changes from each provider continuously. When a provider updates what they accept, we update the templates and rule engine for every merchant on Guzco at the same time. You do not need to do anything; the next dispute uses the new format.

Every dispute gets a full record: the evidence we pulled, the format we submitted, the timestamp, the provider response, and the final outcome. The trail is exportable for accounting and auditor reviews. If your auditor asks how a specific case was won or lost, you can show them in two clicks.
