I went from gopher to jobber. Jobber imported my data from gopher for me at no charge. It made things a lot easier as I have close to 1000 customers. The interface jobber uses is more than adequate and easy to use. I don't miss gohper at all. Most of the things I dislike about jobber is supposed to me fixed in their upcoming releases. The thing I like the most is the great customer support. Many times I request a change and it is released the next day.
The things I don't like about jobber I HATE about jobber. The number 1 thing is you cannot schedule the run sheet. That makes it about useless for scheduling. They do not have a tax report for the different municipalities with different tax rates that I serve. You can only search scheduled jobs not invoices. There are other weaknesses. HOWEVER on the good side is jobber works hard to improve. I suggest going with jobber.
