Website online booking widget!

#1
Can anyone recommend an online booking widget that can install into my website so clients can book appointments?
I need both me and the clients to receive text message and email alerts.

Well I have done a lot of research and tested many online booking software. The best solution i found that can install into my website is from Chatwing. (yes the same Chatwing chat room software provider.

The Chatwing booking solution covered everything i needed including both text message and email new appointment confirmations. You can also choose to send client's text message and email appointment reminders both 24 hours and 1 hour before appointments which is very helpful, the controls are there to choose both options or only 1 of them.
