DDD Invoices closed €1.31M to build infrastructure for the future of tax-compliant e-invoicing

LJUBLJANA, Slovenia - May 14, 2026 - PRLog -- The Ljubljana-based company, backed by Fil Rouge Capital, 500 Global, and experienced operators from the ERP and e-invoicing ecosystem, provides a unified API that connects business and financial SaaS platforms to tax portals worldwide, ensuring every invoice transmitted is compliant with local CTC (Continuous-Transactions-Control), e-invoicing, and fiscalization requirements automatically.

When Every Invoice Must Hit a Tax Portal
Invoicing is no longer a simple exchange between two companies. In many countries, invoices must pass through government tax portals or networks such as Peppol and be validated in real time before being legally accepted.

Each country defines its own formats, rules, and submission logic. For software vendors and fast-growing companies operating across multiple markets, this creates a fragmented system of country-by-country integrations, turning compliance into a structural constraint on growth.

An Invisible Compliance Abstraction Layer
DDD Invoices abstracts this complexity through a unified API for issuing, receiving, and archiving tax-compliant e-invoices. Companies send standardized invoice data, which is transformed into local formats, validated against rules, routed to the relevant tax system, and returned as status updates.

Today, DDD Invoices supports companies including Access Group, Zenoti, Logitude, and WheelSys across multiple markets.

For platforms such as Stripe and Shopify, the company offers native integrations. For unstructured documents such as PDFs, DDD Invoices uses AI-based processing to extract and structure invoice data, enabling compliance and automation from day one.

"Modern software companies cannot afford to be slowed down by local compliance complexity," said Denis Vehovec Pondelak, CEO and co-founder of DDD Invoices. "Compliance is becoming more complex as governments tighten regulations and companies scale globally. We're building the infrastructure to take that off their plate."

Funding the Global Compliance Backbone
With the new funding, DDD Invoices will expand country coverage, accelerate integrations, and grow its product, engineering, and go-to-market teams.

"We're delighted to be the first institutional investor in DDD invoices," said Roger Blott, partner at Fil Rouge Capital. "Fully compliant e-invoicing is essential in commerce today, and DDD is at the centre of this transformation. These services will soon become ubiquitous globally, and we are excited to support their growth."
