Merchant-of-record friction for EU SaaS - local invoicing and procurement layer

Merchant-of-record friction for EU SaaS - local invoicing and procurement layer targets a $150M = 30,000 EU SaaS vendors selling cross-border x $5,000 ACV (annual compliance+procurement enablement) total addressable market with medium saturation and a year-over-year growth rate of 12-18% (growing EU SaaS exports + digital procurement adoption).

Key trends driving demand: E-invoicing mandate -- German public sector requires XRechnung which MRR invoices often do not supply, creating a technical compliance gap; MRR adoption -- more SaaS founders choose merchant-of-record services to outsource VAT and tax complexity, increasing the number of sellers who hit procurement issues; Procurement conservatism -- large German corporates and public institutions prefer domestic invoicing/legal entities, boosting demand for localization and acceptance proof; ERP/e-invoice automation growth -- rising adoption of ERPs and e-invoice validators creates integration opportunities for middleware.
