Hello, linkaxel!
It's nice to see you here in the Community! I'm happy to explain the effects of voiding and deleting an invoice to its linked charges to help you decide.
Voiding an invoice will leave you with a copy of it, but the time and billable charges will remain linked to it. Therefore, you cannot use them on another invoice.
Deleting an invoice will remove the transaction and will unlink the time and billable charges. Therefore, you can use them on another invoice.
That should help you decide what to do, but feel free to comment below if you have further questions. I'll be more than happy to help you again. Take care!
