This looks fascinating. Bookmarking for future purchase.
On that note, you need to adjust your shopping cart. Trial/Basic/Pro should be: Trial/Standard/Professional (or just Pro… I like Professional myself).
You also need to set up the sales like this:
- Standard License ($99)
- Professional Upgrade License ($170) *Requires Standard License
- Professional License ($270)
I would also adjust the license pricing a bit to make it more of an “even” price. Standard License: $99.99, Professional Upgrade: Either $149.99 or $199.99, and the Professional License: Either $249.99 or $299.99. When you get to a point where you’re releasing Version 2 of the software, then keep the same pricing scheme, but also add another category, “V1 to V2 Upgrade License: $49.99 for Standard, $99.99 (or $149.99) for Professional”. Basically version upgrades are half-off the full price of the license.
