Powens vs SlimPay

Powens is an Open Finance and embedded payments platform that connects financial data and payment workflows through APIs. Its aggregation service syncs accounts, transactions, savings, loans, and investments from more than 1,800 banks across 12 EU countries. Accounts refresh daily, while available transaction history varies by bank from 3 to 24 months; live connections can be maintained for six months with daily refreshes. Payment services include IBAN accounts, Direct Debit, Pay by Bank, and instant SEPA transfers through one API and dashboard. Powens says beneficiaries receive funds from its instant SEPA transfers within 10 seconds. It also offers real-time bank identity checks and Spanish IBAN ownership verification. Developers can access API documentation, integration guides, SDKs, connection widgets, an admin console, and a free self-service sandbox. Pricing is on request. Enterprise plans include dedicated hosting and can include an account manager and priority technical and integration support. Powens lists Android, iOS, web, and API access, and says it was founded as Budget Insight in 2012 before adopting the Powens name in 2022.

SlimPay helps businesses automate recurring payment collection through account-to-account payments, direct debits, and open banking services. It supports subscription and invoice payments, along with direct-debit payment method updates. Customers can sign SEPA mandates digitally using a checkbox or one-time password. Supported schemes include SEPA Direct Debit CORE, SEPA Direct Debit B2B, and SEPA Credit Transfer; the service handles euro direct debits and credit transfers for countries within the SEPA jurisdictional scope. Merchants can integrate through a REST API or use File Transfer for batch processing. Checkout can be added to websites and mobile applications using pop-in, redirection, or iFrame options. Payment management is available through a Dashboard, API, or file transfer interface, and failed direct debits can be retried manually or automatically. SlimPay says it is authorized and supervised by France’s ACPR as a payment institution and that its servers are in the European Union with Amazon Web Services. Pricing is available on request, and production accounts require validated pre-production tests and completed KYC.
