I used Gamms Invoice and my client complimented 'nice evolution'. Mind you, I have always sent in a well designed invoice for my design brand but this time, it hit different, away from the normal, something unique directly sent to his email and immediately processed by his bank. The interesting part of this feature is how swift the client recieves the invoice, the clarity in creating it and the seamless flow in usage. How did the scripture say it again 'Old things have passed away, behold all thing have become new with Gamms Invoice'. Have you tried this feature yet?
