As someone, who has built a billing system not once in my life, but twice (one for an internet privider I worked for, which counted the amount of traffic, and another one for a SaaS project(, I fully sympathize with the post. Billing is an unbelievable can of worms even before you get to taxes. Add in all the things the marketing people want from billing (trials, discounts, per-seat per usage pricing, etc), and you have enough tasks to last till retirement, no matter how young you are.
Yep, do agree that non tech team created a lot of pricing complexities, sometimes without any reasons. Remember a marketing team updating plans on webflow and telling the product team « see, not that hard » ;)
Ended up with a whole squad of engineers called « the pricing cross functional team » …
