Hello hChO,

The main way to do so is by activating developer mode, go to the invoices in the list view and (from the header of the table on the checkbox at the left) check all the invoices and now you just need to go to actions and select the option "Resequence".

That will open a wizard where you can give an example in the upper right field and with machine learning it will try to guess how to work it out.
Also I have to add that it won't only resequence all the current invoices but it also applies that sequence the future ones.

Hope you find it useful.
Have a nice day!
