European alternatives to FastSpring
FastSpring operates as a Merchant of Record for software and SaaS companies, absorbing global tax liability in exchange for sitting between the seller and the customer — a model that is operationally convenient but places significant data-processing activity under US jurisdiction, which is an increasingly uncomfortable arrangement for European businesses with GDPR and Schrems II obligations.
The Merchant of Record model has genuine appeal: FastSpring handles VAT registration, remittance, and local-tax compliance across dozens of jurisdictions so that the software vendor does not have to. However, the trade-off is that FastSpring becomes the named seller of record, which means customer payment data, purchase histories, and personal information flow through its US-domiciled infrastructure and are subject to US surveillance law under FISA Section 702 — precisely the legal basis that the Court of Justice invalidated as a basis for unrestricted transatlantic data transfer in Schrems II. European companies that have completed a rigorous Transfer Impact Assessment for their FastSpring relationship will have found this analysis uncomfortable to document.
A second category of dissatisfied FastSpring customers are those who have grown beyond the constraints of a Merchant of Record arrangement. As companies scale, ceding control of the customer relationship — billing communications, refund policies, payment-method presentation, invoicing format — to a third-party intermediary creates friction with their own brand standards and customer-success workflows. The desire to own the full quote-to-cash sequence, including the invoicing and dunning logic, frequently drives the search for a direct alternative.
A third and distinct motivation is developer experience. FastSpring's API and webhook layer reflect a platform built incrementally over many years; engineering teams accustomed to modern, API-first infrastructure increasingly find it inadequate for deeply custom billing implementations. Open-source alternatives with inspectable codebases and Rust or TypeScript-native API layers present a qualitatively different developer experience.

Our honest take
For European software companies seeking a EU-owned Merchant of Record alternative — retaining the tax-handling convenience of FastSpring — Paddle (UK-headquartered, Mixed data location) and Creem (Estonia-registered) are the closest functional analogues, though buyers should note that Creem's data-location status is not fully confirmed and it is not currently GDPR-native by its published documentation; neither is a pure EU-sovereignty answer in the way that fully EU-hosted alternatives are. For companies willing to move away from the Merchant of Record model entirely, Hyperline (France) offers the most complete quote-to-cash automation with certified e-invoicing in 80-plus countries and global invoicing compliance, while Lago and Meteroid both provide open-source, self-hostable billing infrastructure for teams that want to rebuild the stack on their own terms. Mollie (Netherlands, DNB-supervised, PCI-DSS Level 1) is the natural choice for companies whose primary concern is EU-sovereign payment processing with broad European local-payment-method coverage rather than complex billing-logic automation.
PayPro is not a Merchant of Record and does not absorb tax liability — companies seeking that specific capability should evaluate the platforms named above rather than PayPro. Where PayPro is relevant in a FastSpring migration context is again the specific and limited case: a Swedish SME currently using FastSpring for straightforward software payments that wishes to move to an EU-hosted tool combining payments and economic analysis, and for whom the Merchant of Record tax-handling layer is either unnecessary or manageable in-house. For any company whose primary reason for using FastSpring was global tax compliance automation, or for any business requiring deep subscription-billing logic, PayPro does not offer equivalent scope and would not be the appropriate replacement.
