i am as well thinking of switching.
i am looking for something that is good but i can charge credit cards automatically every week. we made the switch this year and it was amazing in terms of cash flow.
we want to switch because of the lack of marketing.
however the one thing that has us with SAP is there credit card integration. as well as a online portal for customers
the only one i found was real green and there pricing was outrages. about 8k for up to 250 customers, and about 200 a month in fees
