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
TeamRaiser is well suited for peer-to-peer fundraising activities, such as large pledge-based events like walks and runs or DIY fundraisers of many different types.
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.
While everydayheroPro and CrowdRise are easy to set up, already mobile friendly, have great interfaces, and are customizable, they lack some base capabilities that come with TeamRaiser, such as the ability to control the donation form, email capability, database syncing, badges/milestones, and custom pages. The everydayheroPro system has great potential, and we use it for our smaller DIY campaigns, but its support knowledge bank and customization is still so limited and can be frustrating to use because of it.
