A fresh $1.5M seed round has landed for DDD Invoices, the company streamlining global invoicing compliance for software providers. The capital, backed by Fil Rouge Capital and 500 Global, will support its mission as mandatory e-invoicing rapidly expands across more than 30 countries, particularly in Central & Eastern Europe.

DDD Invoices offers a single API that allows SaaS, ERP/POS, PMS, marketplaces, and payment providers to integrate complex e-invoicing and fiscalization requirements in days, transforming a regulatory hurdle into a potential revenue stream for its clients.

Belgium went live with mandatory B2B e-invoicing in January 2026. Poland followed in February. France starts in September. Germany's mandate arrives between 2027 and 2028.

For any software company operating across European markets, each new mandate is a development liability, unless your underlying infrastructure handles it automatically. That is exactly what Ljubljana's DDD Invoices - One API, global invoicing compliance is building: a single API that gives software vendors compliance with e-invoicing rules across multiple jurisdictions, without country-by-country
