At Mediod Consulting, we know that efficiency is the foundation of any growing business. Recently, we helped a client overcome a challenge that many European SMEs face: connecting reliable, localized accounting with a powerful global ERP system.
We’re proud to share the story of our latest project—a smooth integration and data migration from sevDesk to Odoo, made possible by our own custom-built sevDesk connector.
The Challenge: Bringing It All Together
Many of our clients appreciate sevDesk for its user-friendly German accounting features and reliable VAT compliance. But as their businesses expand, they need the advanced capabilities of Odoo, like inventory management, CRM, and project management.
Before our solution, the only way was to do everything twice, double-entering data, fixing mismatched invoices, and spending far too many Friday afternoons on manual work. We wanted to make all that a thing of the past.
Our Solution: A Connector Built for Real Businesses
Generic middleware often falls short when it comes to handling specific tax codes or complex contact structures. That’s why we built a custom Odoo module that tackles the details that matter:
Automated Sync: Invoices, credit notes, and payments are synchronized in real time.
Contact Mapping: Customer and vendor data stay perfectly aligned across both platforms.
Tax Logic Integrity: German tax rules from sevDesk are accurately reflected in Odoo’s fiscal positions.
Historical Migration: We ensured that all legacy data was transferred cleanly and audited, with no financial history left behind.
How We Made It Happen
We didn’t just flip a switch. Our team worked through a careful, three-step process:
Data Cleansing: We reviewed sevDesk records to fix formatting errors and remove duplicates before migrating.
Mapping & Configuration: We mapped sevDesk’s chart of accounts to Odoo’s structure so every Euro was accounted for.
Migration: Using our connector, we transferred years of financial data in just hours, then ran a thorough reconciliation.
The Results
The benefits for our client based in Austria were clear right away:
Zero Manual Entry: Invoices created in Odoo now flow automatically into sevDesk for accounting.
Unified Reporting: Leadership gets a full view of the business in Odoo, while the tax team works comfortably in sevDesk.
Room to Grow: The system can now handle ten times the volume without extra administrative work.
