I add the prompt box to let users describe what they wants. Would you mind sharing what is your email in my app? i would love to give you free extra credit to test if you have you time :)
One day, while checking my email, I noticed my customers kept asking about the invoice. I also realized that after I send the invoice, I tend to lose it. This led me to consider building an invoice app that can store the invoice for future audits and can be sent via email.
