If you are doing this for fun, and don't actually need the money that you raise through Flipcause, they're great, but if you need the funds to, say, run payroll or pay rent, do not even THINK of using them. You will spend a lot of time tearing your hair out, and sending yet another email begging them to transfer funds
It is well suited in a public media organization that uses a separate tool for tracking donor touches and engagement and has a separate donation page. In my opinion, it is not a great use case if you are looking for something intuitive or easy to use.
Flipcause has amazingly responsive customer support staff and "Success Teams." When you sign up, your Success Manager makes sure you have all the information and support needed to get up and running quickly and easily. Your Success Team will happily provide support on an on-going basis as needed, although we have not needed much support due to the easy-to-use interface
We previously used Network for Good to process online donations and to sell event tickets, but Flipcause has proven much better at meeting our needs. I prefer the Flipcause interface and functionality, especially for event registrations. We have also used PayPal and PayPal Here to collect donations online and in person. While these are trusted and recognizable for our donors, they are only useful for collecting donations and do not have easily customizable donation receipts.
MemSys was selected because of its features specific to public media. Unfortunately, in my opinion, it does not show features that would enable it to compete with other CRM systems well.
