This is a great read from Modern Treasury. One thing highlighted in this article that the industries not always talk about, is the concept of "Payment Ops". This is critical in FinServ organizations from my own experience. Any good and reliable payments infra is a function of technology, people, and process, and you need good tooling to streamline the whole workflow that involves engineering, finance, credit and compliance teams. Integrating with a payments API is only half of the definition of done.

One thing they don’t get into, but which becomes a significant pain, is what happens if history is wrong — for example, a policy is mis-entered and you need to adjust past financials. I architected precisely one insurance finance system, and trying to recall the data model and logic for overlapping timelines (what was, what should have been, what we thought it was...) still breaks my brain.
