SlimPay review
A focused platform for SEPA Core and B2B collections across recurring and one-off payments.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SlimPay is a European payment platform for merchants collecting one-off and recurring payments. It is particularly suited to subscription, invoice, utility, insurance, transportation, media, fitness, and financial-services use cases that need SEPA Direct Debit Core and B2B mandate support. The platform combines customer enrollment, electronic mandate and document signatures, payment collection, transaction monitoring, reporting, and reconciliation through its Dashboard, Mandate Library, REST API, and file-transfer interfaces. Founded in 2010 and provided by Trustly, SlimPay is designed for businesses managing ongoing direct debit relationships rather than occasional card-style payments.
Commercial access follows a contact-sales model, so buyers should expect a vendor-led purchasing process rather than a public tier comparison. There is no perpetual free plan. The developer FAQ mentions a free evaluation account, which may be automatically deleted, making it more appropriate for initial assessment than for ongoing free usage. For organizations that need a defined self-serve plan structure or a permanent no-cost option, another product may be a better fit. Buyers should also clarify commercial terms directly with the vendor before planning a rollout.
The platform’s strongest area is its coverage of the collection lifecycle. Hosted Checkout supports pop-in, redirection, and iFrame integration, while the Mandate Library centralizes mandate storage and retrieval. Automatic retries and failed-payment management address an important operational part of recurring collection, and batch processing supports file-transfer workflows alongside API-based payment and mandate management. SlimPay should suit merchants that need both Core and B2B SEPA flows with recurring collection controls. Businesses seeking a broader payment scope, a perpetual free plan, or transparent self-serve pricing should compare alternatives.
