Easy Invoice - Zero amount field blocks invoice creation form

[MantisClone]

Problem

When creating an invoice, if the amount field is left at zero (or the user forgets to enter an amount), the "Create Invoice" button becomes disabled. The user cannot proceed and the form appears stuck. The workaround requires clicking outside the field in white space, which is not intuitive.

From the demo:

"If I forgot to put a price so let's say my bit late but if I keep zero. Now it's too late. But if I keep zero and I forgot to put a price so then I have to restart from scratch. The invoice."

Proposed Solution

• Show a clear validation error message when amount is zero or empty
• Allow the user to click the Create Invoice button and show a validation error, rather than silently disabling it
• Consider adding inline validation feedback as the user types

Considerations

• This is a UX issue that affects first-time users during demos
• Priority: Should be fixed before website launch links to Easy Invoice
