I can see a sales invoice in the History but not in the Customer account or the Sales Invoices database

No worries @ishaqster, and thanks for sharing these screenshots.

Your screenshots show nothing out of the ordinary, however, this still doesn’t provide evidence of a bug.

There’s still a possibility of having the reference number changed and then deleted, in which case, there is no possibility of confirming or denying if that ever happened without examining all History entries one by one, unfortunately.

I admit, that this raises a few ideas for improvements in the software to help troubleshoot such situations, namely, a traceback from History to related record for which I will create a separate related topic.

However, for now, we are stuck with troubleshooting the hard way – unfortunately. So please bear with me.

Let’s take invoice #8368 and test the following:

  1. Go to Sales Invoices tab, make sure that Description and Invoice Amount columns are visible. If not, make them visible from Edit columns

  2. Type in the following in the search box “1030x770 Plates 42.0”

See if anything pops up.

An alternative is to copy the entire history to clipboard for Sales Invoice starting from 09-06-2025
