Go to Invoices List and select the old invoices--click on the first invoice in your list, then scroll to the last invoice and shift-click. This highlights the entire range you specified. Right-click anywhere in that range and select Delete Invoices. This will delete that old list of invoices you specified.

Yes. There is a Service that must be running on the host machine. Go to Task Manager, Services, ExpressInvoiceService. Confirm it is running. Right-click and select Start.

I am able to input very long Descriptions that wrap to the next lines. Also, you can shift-enter to advance to the next line within the Item Description field.

You can edit the incorrect invoices and populate (i.e. reassign) to the correct Customer record, then once all reassignments are completed then delete the incorrect Customer record that now has no assigned invoices. You can do a "Refunds and Returns" for your deceased customer.

The default does not stick for me. It depends how you access the Create Invoice screen. I access from the Invoices List screen and must reset each time. I have submitted an enhancement request for the default number of days to stick. Also for there to be a Due Date field that can be directly input into rather than being calculated by the number of days. Also for the Invoice Date to be editable instead of clicking in the month and having to use up-arrow or down-arrow to change the month (same for day, same for year).
