In Dynamics 365 Business Central, you can use the intercompany company transaction functionality to trade with your subsidiaries (that is set up as separate company), the same way as you trade with your external customers and vendors.

Key benefits of this approach are:

  1. Increased productivity
  2. Minimise data entry errors
  3. Complete audit trail
  4. Efficient and cost-effective transaction processes.

An Intercompany Partner Code needs to be set up in each company. You have the option to auto send transactions to the intercompany partner as soon as it arrives in the intercompany outbox, and not have to manually send/receive the intercompany transaction.

Intercompany setup in Business Central

The Company Information needs to be updated. Fill in the Intercompany Partner Code, Intercompany Inbox Type. and Intercompany Inbox Details fields.

You will need to then set up intercompany vendors and customers. It needs to be set up the same way as other customers/vendors. Just be sure to also update the “Intercompany Partner Code” field.

Mapping functionality for the chart of accounts and dimensions help ensure that information appears in the right place. If the chart of accounts and dimensions are consistent across the companies then mapping is not required.

Once the setup is done, you use intercompany documents or journals to post transactions with your intercompany partners. When you post an intercompany document or journal line in your company, a corresponding document or journal line is created in your intercompany outbox, that you can transfer to your partner. Your partner can then post the corresponding transaction in their company, without having to re-enter the data.
