VAT Inclusive option in Sales invoices

we input daily sales from our till Z reading, the till give out a total inclusive of VAT, in which we have to manually deduct the vat before inputting into the sales invoice in quickfile, this can become quite tedious and time consuming when entering a large amount of daily Z readings at once into the sales invoices.
Can there be an option to enter the daily total inclusive of VAT? this will save a lot of time. Thanks

Probably better to do a search first and then add your vote to the existing topic.
