creating an invoice, why is it I have to manually calculate the rate, if I give you the hourly rate and the number of hours? And why does the popup message say 'please make sure the last field contains a number'? Why can't it say "hey, you didn't enter a total"? The 'internal invoice number' on the settings page seems to max out at 2 digits. On the demo account, it's a 3 digit number, but you can't see the third digi…
Not sure about the number of digits in the totals, but obviously this should be unlimited. On our own installation we're in the for digits, so there should not be an issue with this.
Discounts are located in the Financials tab. It's a simple invoicing app, so there's no way to specify a discount based on when the invoice is paid (nor are we likely to implement something like this).
Terms can be placed in the invoice footer.
