Microsoft Dynamics 365 Business Central

Brex now integrates natively with Microsoft Dynamics 365 Business Central, replacing manual CSV exports with a governed, repeatable sync between your spend data and your ERP.

With this integration, you can import GL accounts, dimensions, custom dimensions and more from Business Central into your fields library, so all transactions are coded using your existing ERP structure. From there, Brex supports exporting journal entries and purchase invoices back into Business Central, with real-time field sync to stay aligned as your ERP changes.

For finance teams, this means less manual mapping, fewer export errors, and a faster close across cards, reimbursements, and bill pay.

To get started, prepare your Microsoft Entra ID authentication credentials and Business Central journal setup, and then connect Business Central from the Accounting section of your Brex dashboard.
