cannot enter minus figures on the new lay our invoices

Hi there,

since yesterday (myob updated the program with a facelift) i cannot enter "minus figure on the tax invoice.

Let me explain:

I'm taking some deposit at the time of the booking for the tours I'm providing and then  few weeks before the tour I'm invoicing the cost of the tour MINUS the $200 deposit already paid. 

So I used to send a $200 invoice for the $200 deposit payment and then I will send later on the cost of the tour "MINUS" the $200 already paid.

The problem is that now on the invoice I cannot put the "-$200" deposit already paid on the last line of the invoice.

Any advices?

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.
