Why are my invoice line items being merged together?

Invoice line items usually get merged when the system thinks they’re the “same” line and is configured to consolidate them.
Common reasons:
- Same product/service, quantity, unit price, tax, and discount
- Identical descriptions or item codes
- Grouping/consolidation setting enabled in your invoicing or accounting software
- Import/mapping rules that combine duplicate rows
- Print/PDF layout setting that collapses repeated lines
Things to check:
- Look for a “merge duplicate lines” / “consolidate items” setting
- Compare the line details — even small differences (tax rate, account, SKU, discount) can affect whether they merge
- Check whether line-item descriptions are normalized during import
- See if the same item was added multiple times via template, integration, or automation
- Review any custom code/API logic that builds the invoice payload
If you want, I can help you diagnose it more precisely — paste:
- the software/platform you’re using,
- how the invoice is created (manual, import, API, integration),
- and an example of two lines that got merged.
