DDD Invoices Raises €1.31Million Seed
DDD Invoices closed on €1.31M to build infrastructure for the future of tax-compliant e-invoicing globally.
LJUBLJANA, May 14, 2026 - As governments move into requiring reporting of electronic invoices to local tax portals in real-time, DDD Invoices closes a €1.31M seed round to build the API‑first infrastructure that keeps invoices tax‑compliant by using proprietary AI logic.
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 to ensure that every invoice transmitted is compliant with local CTC (Continuous‑Transactions‑Control), e‑invoicing, and fiscalization requirements automatically.
Invoicing used to be a simple exchange between two companies. However, in an increasing number of countries, invoices must pass through government tax portals or networks such as Peppol and be validated in real time before they are legally accepted and sent to the recipient.
Each country defines its own formats, validation rules, and submission logic. For software vendors serving customers across multiple markets and for fast-growing companies operating through multiple entities, this leads to a fragmented, expensive system of country-by-country integrations. Compliance stops being a local configuration issue and becomes a structural constraint on growth.
DDD Invoices abstracts this complexity through a unified API for issuing, receiving, and archiving tax-compliant e‑invoices, offering an all‑encompassing solution for modern scaling. Companies send standardised invoice data; DDD Invoices transforms it into local formats, validates it against current rules, routes it to the relevant tax system, and returns status information to the original application. Today, DDD Invoices already supports software companies including Access Group, Zenoti, Logitude, and WheelSys across multiple global markets.
For companies using platforms such as Stripe, Bitrix, Shopify, and Chargebee, DDD Invoices offers native integrations. For unstructured files such as PDFs, the company uses AI‑based document processing to extract and structure invoice data. This way, they ensure companies can achieve 100% compliance and automation across all their flows 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 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.”
As investors back this new infrastructure layer, the focus is on country coverage and on the ease of delivering value to clients.
With the new funding, DDD Invoices plans to expand country coverage, make integrations faster and easier to deploy, and grow the team across product, engineering, and go-to-market.
“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 a necessity in commerce today, and DDD is at the centre of providing this essential service to its customers. Globally, these services are in their infancy, but in a short time, they will become ubiquitous, and DDD has a second-to-none solution. We are looking forward to participating in DDD’s successful and exciting growth story.”
