Adobe Creative Cloud (as well as how streaming services have made people at all levels inured to low monthly subscriptions) has made this type of monthly pricing much more normalized - good for providers who can now point to recurring revenue, not so great for users who usually end up paying more.

It's worth considering what your particular customers want. I make Photoshop plugins, and since the CC subscription came in, I've heard of a lot of customers jumping ship to one-off purchase products, like Affinity Photo and Paint Shop Pro. But some other customers are happy with it.

Also, while Creative Cloud is paid monthly, individual plans have a minimum term of 12 months. If you cancel, you have to pay out 50% of the contract term (unless you prepaid for the year, in which case there are no refunds).
