For our use, I think each person will need a copy of FileMaker Pro 14:
We don’t need the “advanced” version because we are just using this as end clients and somebody else is doing our development.
The cost is $329 per copy for a perpetual license. But there is also this option which might be more attractive:
As you can see there, you can purchase annual licenses, which are just $9/month per license. But it seems they need to be purchased annually, which means it would be $108 per license per year. So it would take 3 years to match the cost of the perpetual license.
Since FileMaker aggressively upgrades every year it seem the annual license might be the best way to go.
What do others think?
