Last week we asked Brigada readers what you use for donor management: https://brigada.org/2022/10/02_36635/comment-page-1#comment-426736.
Pam replied that they use and love Donorbox, which can be found at https://donorbox.org/. “It is easily customizable, accepts donations from around the world in any currency, and in the three years of using them, there have been no errors (other than our own!) Their helpdesk is the best ever. Highly recommended.” Have you used it? What donor management software do you use? Please comment.
We use Little Green Light. Same experience as above. It’ also has a built in form system for event registrations and payments.
I think that Salesforce.com provides an annual grant of 5 seats for no charge to approved not-for-profits. It includes a plug-in that is preconfigured for grants and donor management.
