Hi sknight3, QuickBooks Online currently supports third-party payments through PayPal and GoCardless (for direct debits). If you don't wish to use either of these options, you can also enter your payment details on the invoice for the customer to pay manually via their chosen method. PayPal is a popular option for our customers, and if you do have any specific concerns on the integration, please get back to us below.
If you are running a service company, you can utilize a proposal management app to integrate with QBO and accept payments by Visa, MasterCard, American Express, Diners Club (International), Discover (Domestic) and Direct Debit (BACS).
