Best Modular Application on the Market
I recently started coaching at a gym that trains athletes. We needed a better way to keep track of our clients, their tests, their payments, and workouts. I had looked at all the "off the shelf" applications that were 'designed' for gyms, and none of them did everything we needed. In a few weeks with QuickBase, I had a fully customized and functioning application for our business, and the feedback from clients is great.
Customizable to what you need and how you want it, (but you have to know what you want)
Pretty expensive if you are only 1 or 2 users, you'll have to find a way to combine efforts with other users if you are a less than 3 man shop.
QuickBase is much more powerful and can do a lot more than sales force
Excel is a trap and will cripple any business
Client CRM, Progression tracking
Better visibility to our active clients and who is actually coming to the gym
Find somebody or some company that develops QuickBase applications to help you get started, but then you can make all the changes you need to on your own after that.
