I know it's hard to place a value on how much a utility saves a business, but honestly this math is like the piracy math and we didn't buy it back then either.
Some teenager downloading 20k songs does not mean that they saved $20k[1], nor does it mean that the record labels lost $20k.
In your case, the relevant question is "how much did your revenue increase by after you started 10x your utility code?"
[1] Assuming the songs are sold on the market for $1 each.
OP wanted a thing. in the past, they've been OK paying $10k for similar things. now they're paying $200/month + a bunch of their time wrangling it and they're also OK with that.
seems reasonable to consider that "$10k of value" in very rough terms which is of course how all value is measured.
Okay, then their costs should have come down similarly, no? OP said they were a business and that these weren't luxury hobby things but business needs. In which case, it must reflect on the bottom line.
I operate as a business myself (self-employed), and I can generally correlate purchases with the bottom line almost immediately for some things (Jetbrains, VPSes for self-hosted git, etc) and correlate it with other things in the near future (certifications, conferences, etc).
The idea that "here is something I recently started paying a non-trivial amount for but it does not reflect on the bottom line" is a new and alien concept to me.
