We would LOVE to have a text messaging system in Reckon that would allow us to send our employees text messages via our desktop computers. This would save us so much time as our employees are constantly changing.
While not integrated into Reckon any way at all, You can use a 3rd party product to send text messages. Most have a web interface and/or desktop applications. They also have a address book to send messages out, so no need to enter the mobile numbers all the time.
