DDD Invoices raises €1.31M to simplify global e-invoicing compliance

DDD Invoices, a Ljubljana-based company building API-driven infrastructure for global e-invoicing compliance, has raised a €1.31 million seed round backed by Fil Rouge Capital, 500 Global, and experienced operators from the ERP and e-invoicing ecosystem.

The company is also supported by angel investors and advisors from the e-invoicing and ERP ecosystem, including former executives and founders from IFS, Pagero, Tickstar, Arratech, and Docupath.

As governments increasingly mandate real-time e-invoice reporting to local tax portals, businesses and software providers face growing compliance complexity. Different countries apply their own formats, validation rules, and submission requirements, creating costly and fragmented integrations for companies operating across markets.

DDD Invoices is building an API-first infrastructure designed to simplify this process. Through a unified API, the company connects ERPs, accounting systems, and SaaS platforms to tax portals, Peppol networks, and real-time reporting systems worldwide.

Its platform automates the issuing, receiving, and archiving of tax-compliant e-invoices across jurisdictions while ensuring compliance with local Continuous Transaction Control (CTC), e-invoicing, and fiscalization requirements.

The company uses proprietary AI-driven logic to transform standardised invoice data into local formats, validate invoices against current regulations, route them to the relevant tax systems, and return status information to the originating application. For unstructured files such as PDFs, DDD Invoices also applies AI-based document processing to extract and structure invoice data automatically.

Denis Vehovec Pondelak, CEO and co-founder of DDD Invoices, said modern software companies are increasingly challenged by local compliance complexity as they scale across markets.

Compliance is already not the most exciting part of building a company, but now it is becoming increasingly more complex due to governments tightening the regulations and companies scaling globally from the get-go. We’re building the infrastructure to take that off their plate.

Founded by a team with more than 30 years of experience building business software, including ERP systems for public and private institutions, DDD Invoices is already working with companies such as Access Group, Zenoti, Logitude, and WheelSys across multiple global markets. The platform also offers native integrations with systems including Stripe, Bitrix, Shopify, and Chargebee.

With the new funding, DDD Invoices plans to expand its country coverage, accelerate deployment and integration capabilities, and grow its product, engineering, and go-to-market teams.
