The USD 5.00 per month thing is relatively 'cheap' but the designers of the pricing model don't take into account all the other services people are signed up to. This is why super cheap tiers are great, like $1.00/mo tiers where I may not get all features, but at least I get to save some money. Spotify, Netflix, Hosting, Domain Renewals, etc all start to add up.
> ... business ... purpose is ... to survive, and ... to maximise profit ...
That is kind of like saying the purpose of human life is breathing. Yes, breathing is critical and fully integrated into existence, but there is so much more to living well. Similarly the purpose of business is to create value. Survival through flows of money comes as a result of that. Money dominated conversations can help, but often miss fundamental issues. For example, there is a big psychological difference between a software service with regular payments versus occasional software releases that can be bought and owned. With the right pricing the two are essentially the same, but customers tend to have very different feelings toward each model.
Does anybody have a similar article about service or productized service oriented pricing for agencies?
Interesting wrap-up. Most of these things are probably known eve to certain laymen, but good to have them altogether.
Bessemer has created a similar roundup/guide: https://www.bvp.com/pricing-course
For devs who need to implement some type of system to support all these pricing models, we recently started working on https://priceops.org
Are there other good business resources like this for tech entrepreneurs?
I'd say it's worth noting that this only applies to SAAS. There's a giant pile of things missing from this if you have inventory, manufacturing or anything else more complex than software and developers.
Pricing is an unbelievably complex subject which this doesn't get close to discussing properly.
