The ability to create a presale or mark sale/invoice as a presale so when the part is received you can then mark the invoice as a sale/invoice and it posts the date the invoice was marked. Not that date of the invoice.
This would help with the never ending issue/work arounds with zero costing.

This would almost act as a quote, that can accept a payment but not require the extra work on the back end of converting it to an invoice after the fact, it would not cause the issues with cash end of day reports that don’t show payments not applied to an invoices or cause delay to book keeping and reconciling because payments aren’t posted.
