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.
