cannot enter minus figures on the new lay our invoices

Hi KI_Guide 

Thank you for your post. The option to type a - into that field is not there because it's not possible to sell an item where the value of the item is less than zero, that would mean you are selling something for a negative amount.

The way to do a credit and a debit on the same invoice would be to put -1 on the 'No of units' field, instead of the 'Unit price' field.

Hope that helps.
