right now there is no way other than manually donation by donation to transfer information from NationBuilder to QUickBooks online (as far as I know). Since QuickBooks online will accept credit card donations (one-time AND recurring payments) for a competitive price to those processors you currently support ($19.95/month plus 1.7% - 2.5% plus $0.29/transaction) it would be a TREMENDOUS benefit if Intuit could process contributions through NationBuilder that show up in QuickBooks online. Can this be done?
The only way of doing recurring payments now via NB is through PayPal, and that requires the donor to create a PayPal account, not just use a credit card. Many donors won't do that: "too confusing" and "too many repetitive steps" are the most common complaints.
Broader support for exporting other types of donations manually entered into NB --- checks, money orders, cash, etc --- to QB would also be supported, but the credit card processing would be the most valuable.
