Problems with homemade billing systems
Good article, and I generally agree that people are too quick to say “Ahh, this looks like a two week project” and ignore broader complexity. I’ve definitely seen a fair amount of that.My question is, how do I know that the OTS solution would actually be much better? For example, OP describes some tricky migrations from one type of billing to another, or complex grandfathering schemes - how would you have any guarantee that your third party solution would be able to support those? At least if it’s in-house you can implement the needed functionality eventually - if it’s third-party it might just be flat-out impossible.
