How hard is it to switch payment provider? And in particular, how hard is it to get corporate cards from banks? No offending, just curious the reason behind all this.
That totally depends on the new provider. One of the nice things about Stripe was their APIs and SDKs were so easy to use. As a solo dev, I was able to spin up a site in a very short amount of time.
If the new provider has less features/ease-of-use, then you have to start from square one on integration. If you have a team, then maybe not as big of a burden as being a solo dev.
