A small team, deep in invoice flows.
Kleinkode is an IT consultancy based in Belgium, specialising in two things that belong together: system integration and Peppol e-invoicing. We help finance and IT teams replace fragile, manual invoice processes with integrations that run quietly in the background.
The company grew out of implementation work. After years of ERP migrations and e-invoicing rollouts, the same pattern kept appearing: the invoice was technically correct, but the data behind it was not — and nobody owned the flow end to end. So we built a consultancy around that gap, working with Belgian and European companies that invoice across borders and need one team accountable for both the integration and the compliance.
A small consultancy, by design.
Kleinkode brings IT engineering and Belgian e-invoicing together in one team — close enough to the details that nothing gets lost in translation.
What we are
A small, specialised consultancy working in one field: business systems that talk to each other, and invoices that travel through Peppol without friction.
How we work
The team stays deliberately small, so the people who scope your project are the people who build it. No account layers, no handovers, no relay.
What you get
One architecture instead of two separate tracks. Integration and e-invoicing are designed together, delivered in short sprints and documented as we go.
