Frequently Asked Questions

What exactly do you deliver?▼
Depending on the package: UBL mapping documents, transformation specifications or code, validated test invoices, training materials, and comprehensive documentation. Everything you need to produce compliant e-invoices.
Do you write the code or do we?▼
That depends on your needs. We can deliver specifications for your developers to implement, or we can write the code ourselves. Enterprise packages include pair programming with your team.
What if it doesn't work?▼
We guarantee that the implementation will produce valid e-invoices that are accepted by Peppol and receiving systems. If not, we fix it at no additional cost.
How do you compare to hiring a consultant?▼
Generic IT consultants often don't know Peppol/UBL specifics. We're specialists with Invoice Navigator as our toolkit. Faster delivery, lower cost, guaranteed results.
What about ongoing compliance?▼
E-invoicing regulations evolve. After implementation, you can subscribe to our Managed Compliance service (from €300/month) for ongoing support, updates, and monitoring.
