When we launched in 2017, we went "in-house" with our billing. We found an open-source project and uses that for all billing as it had a recurring option and a billing portal.

We can still adjust invoices, keep old pricing, setup new pricing, auto-bill, check balances to see if a customer hasn't paid yet. Total Lines of Code here are like under 2000 for this integration and it's great. Also zero vendor lock in as well. Just another way to approach a billing system.
