SlimPay

Overview

SlimPay is a business payment service for collecting recurring payments by direct debit, credit transfer and open banking. It is best suited to businesses that need SEPA payment collection and can complete a production-readiness process. Its focused payment tools are useful, but it is not a platform for managing subscriptions or customer relationships.

Key features

SlimPay supports recurring subscription and invoice payments, as well as direct-debit payment-method updates. Customers can sign SEPA mandates digitally by checkbox or one-time password, which gives businesses a way to handle mandate authorization as part of a digital payment flow.

Its scheme coverage includes SEPA Direct Debit CORE, SEPA Direct Debit B2B and SEPA Credit Transfer. Direct debits and credit transfers are in euros and cover countries in the SEPA jurisdictional scope. That makes SlimPay a focused option for euro-denominated SEPA collection, not a general-purpose international payments service.

Businesses can integrate through a REST API or use file transfer for batch processing. Checkout can be embedded in websites and mobile apps through a pop-in, redirection or iFrame. Accounts can be managed through a Dashboard, API or file transfer interface. Manual and automatic retry options for failed direct debits help address collection failures, though the choice of retry approach remains with the business.

SlimPay says it is authorized and supervised by France’s ACPR as a payment institution, is subject to GDPR requirements, and hosts its servers in the EU with Amazon Web Services. Its developer center directs users to a dedicated team for questions about errors and documentation. Production accounts follow validated pre-production tests and completed KYC, so businesses should plan for those steps before going live.

Pricing

SlimPay is paid, has no free plan, and offers a Production service with custom pricing. The service includes both payment frequencies and both scheme types, plus mandate management, API access and a hosted payment page. With no published price or free tier, it is a poor fit for teams that need to estimate costs from a self-serve rate card before speaking with the provider.

Platforms

SlimPay supports Android, iOS, web and API access. Its checkout options cover websites and mobile applications, while its API and file transfer interfaces support direct integration and batch processing.

Who it's for

SlimPay suits businesses collecting recurring euro payments within the SEPA jurisdictional scope, particularly those that need CORE or B2B direct debit, credit transfers, digital mandates and configurable checkout integration. It is not an ERP, CRM or subscription relationship-management platform; businesses needing those functions should pair it with other software.

Pros and cons

• Pros: Supports CORE and B2B direct debit alongside SEPA credit transfers, giving businesses more than one SEPA collection scheme.
• Pros: Offers API, batch file transfer and several checkout integration formats, accommodating different implementation approaches.
• Pros: Digital mandates and manual or automatic retry options address authorization and failed-collection steps in recurring payment operations.
• Cons: Euro and SEPA-jurisdiction coverage limits its fit for businesses seeking broader payment geography or currencies.
• Cons: Custom pricing and no free plan make it harder to assess cost before contacting SlimPay.
• Cons: Production access requires validated pre-production tests and completed KYC, adding prerequisites before launch.
• Cons: It does not provide ERP, CRM or subscription relationship management, so it cannot serve as the whole customer-management stack.

Alternatives

For a different direct-debit option, compare the Direct Debit Processing Software category.

Twikey is worth comparing if you want published monthly plans: Lite is €78 a month and includes SEPA Core mandates, SEPA B2B mandates in the Netherlands, online payments, Request to Pay, payment links, one PSP, one brand and two users; Professional is €145 a month.

Access PaySuite Direct Debit may suit small and medium businesses that prefer a per-contact charge starting from £0.08 per contact, with final pricing depending on monthly volume, average transaction value and SUN or Facility.

London & Zurich Direct Debit is another option for established organisations, with a Business plan priced from 0.5% or 20p and including a branded SUN, Bacs compliance, onboarding and team training, API and integrations.

InterPay + DDMS is a web-based alternative with tailored pricing through Interbacs consultation.

Razorpay e-Mandate is another paid option for Android, iOS, web and API platforms.

Cashfree eNACH is a paid option billed for mandate creation and per presentation, with a separate platform fee.

AccessPay uses a flat annual subscription priced according to estimated annual transaction volumes, users, data configurations and submission workflows.

IBANC pay-collect-control may appeal to teams seeking a non-recurrent desktop plan: IBANC Standard costs 279.00 EUR once and includes one own bank account, batches of up to 1,000 transactions, CORE SEPA direct debits and SEPA credit transfers.

Verdict

Choose SlimPay if your business needs recurring euro payments across SEPA schemes and values a choice of API, batch processing and checkout integrations. Its strongest case is focused SEPA collection with digital mandates and retry options. Look elsewhere if you need transparent upfront pricing, broader geographic or currency coverage, or subscription and customer-management software in the same product.
