How to Set G/L Account as Default Line Type in Dynamics 365 Business Central

Today we will learn how to set G/L accounts as the default line type in Dynamics 365 Business Central for your sales and purchase invoices.

This setup is very helpful when you want to save time. Instead of manually changing the line type from "Item" to "G/L Account" on every single transaction, Business Central allows you to change the default setting, so it populates automatically. This reduces manual work and speeds up data entry.

If you want to set up dimensions correctly and avoid reporting issues later, working with a Microsoft dynamics 365 consultant can really help.

What Is the Default Line Type in Business Central?

By default, Business Central often assumes you are selling or buying items. If your business primarily deals with G/L accounts, you can change this behaviour. By updating the setup, every time you open a new invoice, the first column is already set to "G/L Account" without you having to click anything.
