QBMS and QB online linked to authorize.net

[BSME]

I was trying to use QB online and have it linked to QBMS and a.net
QB support said QB online couldn't be used with an e commerce merchant account, they want to use QB pro with a QBMS and a.net all of which have monthly service fees...

I was also talking to B of A about their merchant acct. which seems expensive but could be worth it if it links to by online banking.

I want to have everything linked together and online somehow, because I sell around the state at art shows and online so I want to be able to log in anywhere, make invoices for cash, check or CC and keep track of everything in one QB or other accounting software.

Does anybody have a solution?

Has anybody used?
