Guzco has partnered with Mollie to automate chargeback and dispute resolution for online merchants.
The integration links Guzco's dispute-management technology directly with Mollie's payment infrastructure, allowing evidence for contested transactions to be gathered and submitted without manual intervention from merchant support or finance teams.
Mollie provides payment processing to more than 250.000 businesses across more than 30 European markets. Several merchants, including Otrium, Loavies, Proforto, Zelesta, Cloudpillo, and Hang Eleven, already use both platforms.
Automating evidence collection
Chargeback defence has traditionally required manual work, with merchant teams gathering delivery signatures, return statuses, and order logs from multiple carriers and platforms before compiling a case. Through the partnership, Guzco automates this process by extracting tracking data from carriers and building structured evidence packages that are submitted directly to Mollie's dispute portal.
The system covers a range of payment methods, including Mastercard and Visa card payments, Klarna, Riverty, and PayPal. For each dispute, Guzco maps the specific documentation required by the relevant dispute code, so that submissions include the proof relevant to that claim. The service also tracks response deadlines on an ongoing basis to ensure evidence is filed within the required window.
In addition to defending against disputes after they arise, Guzco scores orders using carrier data before shipment, through a partnership with logistics provider PostNL, with the aim of identifying and reducing the likelihood of disputes before they occur. Merchants can also monitor recovered revenue and win rates alongside their existing Mollie transaction data.
Integration and onboarding
Merchants must hold an active Mollie account before setting up the integration. Onboarding requires a signed agreement with Guzco, a data processing agreement, and admin access to the merchant's webshop. Once these are in place, merchants grant API access to connect Guzco to their Mollie account, after which Guzco imports historical payment and dispute data to provide an initial view of win rates and revenue loss.
Furthermore, merchants then connect additional data sources, including their webshop, shipping carriers, and returns provider, in order to supply the evidence required for dispute submissions, and define which types of disputes should be handled automatically versus flagged for manual review. Once configured, Guzco continuously monitors incoming disputes, compiles supporting evidence, and files responses ahead of applicable deadlines.
Industry context
Chargeback management has become a growing operational cost for online merchants as transaction volumes and payment method diversity increase. Through the process of linking dispute automation directly to an existing payment processor's transaction records, the partnership addresses a common friction point in ecommerce operations: reconciling evidence held by a payment provider with the documentation needed to contest a claim. Rutger van Boxtel, COO of Otrium, said the integration has allowed the company's team to stop manually compiling chargeback cases, noting that claims previously written off are now being recovered.
