How to Setup Customer Posting Groups in Business Central

Setting up Customer Posting Groups in Microsoft Dynamics 365 Business Central (BC) is one of the most important steps for getting your accounting right. If you do not set this up properly, customer transactions (like sales invoices or payments) may not go to the correct accounts in your books.

Don’t worry it’s easier than it sounds! Let’s go step by step in simple English over How to guide series.

What Are Customer Posting Groups?

Think of Customer Posting Groups as a link between your customers and your accounting system.

• They tell BC which General Ledger (G/L) accounts to use when customers buy something, get discounts, or pay invoices.
• Example: Domestic customers may post to one set of accounts, while International customers post to another.

This saves time and avoids mistakes because you don’t need to select accounts manually every time.
