I love that it syncs with our website so we can create an invoice or receipt from anywhere on our site without having to send an email out to everyone involved in the transaction. There are many different templates available and it's simple to customize them to fit our needs. Sometimes it takes a while to sync up with our system if we make a change but that could be because of the difference in platforms. It also can take time for the customer to upload their proof once they receive it. We use this app mainly for creating receipts and invoices for customers.
