Documents & receipts
Invoices, receipts and emails are read, sorted and handed over to your accounting or ERP, with the original attached.
Result: Less typing, fewer errors and a complete month-end folder for your tax adviser.
Practical. Privacy-compliant. Verifiable.
We take repetitive work off your desk: reading documents, finding information, drafting texts, connecting your systems. Your data is hosted in the EU, and you decide what needs a person's approval before it goes out.

Three concerns we hear most often: data going to the US, AI inventing things, and becoming dependent. This is how we address them.
Hosting in the EU, local AI models on request and a data processing agreement under the GDPR. Your data is not used to train AI models.
You decide what needs a person's approval. Automated steps are logged, so you can see what happened and when.
Your code, your server, open formats. We use whatever tool fits the job, and you can carry on without us at any time.
Systems we have built and run in daily use. No mock-ups, no demos.
Client: vitalpilze.de (GfV)
Searches PubMed every day for new scientific studies, filters them, summarises them in German and assigns them to indications. The language model runs locally on our own server. An automatic check rejects figures in the detailed summary that do not appear in the source. Uncertain cases go to a review queue: the client decides what is published automatically and what needs a person.
Client: deja ltd, GfV, MSBC
Invoices and collective subscription invoices, payment providers (Stripe, Mollie, PayPal), e-invoices in ZUGFeRD format, receipt mailboxes and the monthly export to the tax adviser, all in one system.
Client: MSBC Converter
A SaaS application for moving from an old ERP to Microsoft Business Central. At its core is the mapping: every field of the new ERP is assigned a field from the old system, a fixed value or a conversion rule, so the old data arrives exactly in the structure Business Central expects. It reads any system that exports Excel or CSV. From the order through payment to provisioning, every step runs automatically.

A first working version, used in your daily work and measured against the goal we agreed on.
