Yes, Easy Route is DOS. A few years ago, I gave it a look, but I too could not overcome the lack of windows......
Although it may be effective, it worried me that any company would continue to market a product based on DOS in this day and age. I'm sure it is a very effective product, since I know David S. wouldn't tolerate it otherwise.
Of course, in the end, you need to decide for yourself. ServiceCEO has many many advanced features that could benefit your company, but then again, they may not. You need to take a close look at what you need it to do today, tomorrow, and in the coming years and make your own decision.
I purchased ServiceCEO a few years ago, but never fully implemented it since I scaled back my business shortly after that. I intend on using it in a future business endeavor.
What impressed me the most about the product was Insight Direct's obvious committment to improving the software. Every time they took on a new large client, they would develop new features for that specific client. Shortly after they would release those improvements in an update for all of the users to enjoy. I watched the product evolve over the course of at least two years, and when I was ready.......I gladly jumped on board.
There are many impressive functions in CEO, but my favorites are the Dispatch Board, and MapPoint integration.
If you choose to go with a program such as EasyRoute, I'd do some research first to plan an "escape route" for your business should the software fail or no longer be supported. What would you do if your business relied on this software, then all of a sudden it didnt function anymore? Would you have the time it would take to re-enter your data into another program and learn another program? Not likely.
I would call Insight Direct and tell them you are an EasyRoute Plus user that wants to transfer to ServiceCEO. Find out if they have the ability to pull all of your information out of that program and insert it in CEO. They probably do. Assuming they do, then you would have less to lose by going with EasyRoute.
I was still in grade school when most programs got away from running in DOS. Putting the functionality of the software aside, EasyRoute doesn't project an image that makes me comfortable putting the future success of my business in their hands. Neither their website nor their program's interface look professional in my opinion. I remember feeling that way years ago, and I think the same thing as I look at it right now and nothing has changed.......
Good luck to you!
