I used to have Square and I can say that Square estimate/invoice system is far superior than Clover. I will really appreciate if Clover can match the capability that Square has for the invoice and estimate.
I send a lot of wedding and special events invoices and we like to make them with all the details of their purchase. We will like that Clover lest us select the items that we have on our menu to add it to the invoice or estimate, add the quantity needed, add a description, date of service, reminders, the option to make a deposit, the ability to modify the invoice whenever is partially paid. etc.
This feature is under review.
