I designed an automated Navision → n8n → Odoo → Peppol workflow. Navision generates a daily Excel export, which n8n automatically retrieves, parses, validates, and maps before using the Odoo API to create customer invoices with their corresponding invoice lines.

The workflow also includes error handling, logging, validation, secure API authentication, scheduling, and failure notifications. Once invoices are created in Odoo, its standard Peppol functionality handles electronic delivery to B2B customers. The solution reduced manual invoice processing, created a more transparent and traceable workflow, and provided a scalable foundation for the company's transition from Navision to Odoo. It also prepared the invoicing process for Peppol e-invoicing while keeping Navision as the primary accounting system during the transition.

I'd want a reconciliation check between each daily Excel export and the invoices Odoo actually created. If one row fails after the others succeed, does the next run resume just that row?

I built HomeCare Pro, a complete booking platform for a home-service business in Lahore. It lets customers check real availability, book, reschedule, or cancel appointments without back-and-forth. I built it to reduce the owner's manual work, prevent scheduling conflicts, and turn inquiries into confirmed bookings.

I also want to build an app like this one but you have build it. That's amazing
