Your service has been a saviour for me. I did order from a night delivery service at 3AM, as order arrived I realised I burnt all my cash that evening in a pub and I was in a small hotel. And there I checked the SMS, clicked on the link and paid. I was so happy I can't tell you, else I would have to go to ATM at night, that would have sucked.
Integration was quick and easy. Your on-boarding process looks to be designed perfectly for businesses who are super busy with their daily operations.
Stellar Product. Keep Rocking.
