In a smaller business Odoo is at the centre; in a larger group it sits at the edge. We link it to banks, e-invoicing and the Peppol network, web shops, couriers and payment providers, and within a group to the SAP core for consolidation and intercompany trading.
Most links run directly through Odoo’s external API. Once volumes rise, or several systems rely on the same data, we place an integration layer in the middle, so an upgrade to one system does not break the rest. Our integration and API team designs those contracts.
