There is a decent range of businesses who are well-served by going the Payflow route -- government offices, non-profits, Universities, etc... Generally small-to-mid-sized businesses with small-to-mid-sized payment processing needs. It's been a while, but I've set up a few Payflow-based systems, and it's been a great way to go... Payflow allows you much more control and detailed logging than, say Stripe. Yes, it's a bit of a pain to get it all set up at first, and there are a few tricks with error handling, but it's a good way to go to implement your own payment system.
