Do you think that if someone told you that you wouldn't have built BCC? What I'm really asking is can you make everything reoccurring or are their certain markets that won't tolerate it.
I believed very strongly in 2006 that teachers would never go for recurring purchases. I also thought that there were only ~1,000 people in the entire world that would ever buy bingo card creation software. Belief #2 is demonstrably catastrophically inaccurate.
That's a week or two of work (BCC is kinda creeky) and a whole lot of future customer support headaches to do that test (+), and the future revenues of BCC are the least important thing for my business success. I'd much rather spend the time on e.g. marketing AR and trying to 10x it's current revenue, or just do a week of consulting.
+ Despite having a totally consistent policy on this for the last five years, I have customers who either a) can't read and understand that BCC is a one-off purchase or b) actually think that BCC is billing them monthly (for free trial accounts) and want to cancel them to stop the billings on their Googles.
This bit of advice is probably in the top 3 of "Things I wish someone had told me in 2006."
