Could be $10K, could be $200K, depends on your tolerance for risk. And, yeah I was thinking online only. If you need card readers you're pretty much stuck with one provider. Where I've seen people get in trouble with their payment processors it has only been online. Terminals are rather difficult to misuse these days. If you deal with both online and card readers, keep those on separate accounts. That is two account at the payment processor (PSP) and two accounts with the acquirer company.
