No Annual or Recurring Fees
Don't you hate when you go to buy software and they want to charge you every month or year to use their software? It would be so much easier to just buy it once and be done. Once you buy Pentacalc you have a lifetime license to use it. A simple one time purchase.
What does the lifetime license include?
Each person using the software needs their own license. Each person can install it on as many machines as they personally use, but each person needs their own license. So if you are an accounting firm with 5 employees that use Pentacalc you need 5 licenses. No more no less.
