If your Profit & Loss statement needs to show Electronics revenue separately from Services revenue — or your accountant wants cost-of-goods broken out by category — product groups make that happen automatically. Instead of all product sales posting to a single revenue account, you route each category to its own GL accounts. Your financials gain granularity without adding any manual work at transaction time.
Open any product record and select the Product Group from the dropdown. From that point on, all transactions for that product post to the group's GL accounts automatically.
Tips
Product groups are optional. If your revenue structure is simple and a single set of GL accounts covers everything, there's no need to add this complexity — keep it simple.
Define your GL account structure with your accountant before creating product groups. Reassigning accounts after transactions have already posted requires careful historical reconciliation.
Groups pay off most when your accountant produces a Profit & Loss statement that needs separate lines by product category — the segmentation flows through automatically without any extra Journal Entries.
This is an advanced feature. Work with your Accounting team to define the GL account structure before creating product groups.
