1. When attempting to create a new invoice through Pino, the application unexpectedly closes completely. Instead of proceeding with the invoice creation process, the system crashes and terminates the application, preventing the user from continuing the operation.

   2.The quantity field should include “-” and “+” buttons to allow users to easily decrease or increase the quantity value. The buttons should function properly and update the quantity dynamically based on user interaction.
   3.When tax is enabled, the item amount is currently being displayed inside the tax section. The item amount should be displayed separately outside the tax section for better clarity and proper invoice calculation structure.
