| > you can probably offer them a price that works for both of you There is no such price, because there is no way to sustainably develop a product without subscriptions. You can't go to a local bakery and pay $24 for life to get fresh rolls every day. Every one-time price is a gamble, where somebody is betting on something. It's a way to close your eyes and pretend ongoing costs do not exist. |
This is clearly incorrect given that there are plenty of software developers who offer lifetime purchases. In fact there was a time that subscriptions for software were virtually unheard of.
On a lower level, all that matters is the numbers. If your average customer stays subscribed for 24 months, then charging a lifetime fee equal to 24 months is equivalent to a subscription model. At that point it's irrelevant what's "sustainable" since 24 months is the max you can expect to charge on average anyway.
