I am experiencing this issue as a paying customer trying to pay with credit card.  (As a small business owner who's considered using QB for invoicing, this makes me very weary.)  I'm trying to pay a QB invoice from a small business owner for a home construction job. Our understanding was that I could pay with a credit card (so I can pay for this job over a few months).  I get this same error message every time I input my Capital One credit card info. The business owner is basically saying, "Oh well, I can't do anything about this. Pay in cash." So I'm trying to figure this out (to my benefit, of course; he's probably hoping I'll have to pay in cash. I'm the only one benefiting from using credit) .  Can Quickbooks, or anyone else, PLEASE provide some updated information about this?: What is causing this issue? Will this problem be resolved within the next 30 days, so I can hold out and eventually pay with my credit card? Is this an issue with Capital One, only? Would it work if I got a credit card from a different company? Any help with this would be very appreciated! Thank you!
