Every gift, thanked.
Coffer takes donations, keeps every donor's story, sends the receipts and thank-yous, and shows who needs a call.
100% free, open source alternative to
Bloomerang, Little Green Light and Neon CRM
Online giving
Give in a minute.
Donation forms and campaign pages with monthly giving, card, bank and Apple Pay checkout, and a portal where donors update their own card.
Donors
Every donor's whole story.
Households, relationships, every gift and every conversation in one place, with soft credits, tributes and employer matches.
Payments
Every dollar reconciled.
Gifts, fees, refunds and failed monthly payments sync from Stripe as they happen, and each payout matches its deposit in QuickBooks Online or Pantry, split by fund.
Receipts
Receipts go out on their own.
Thank-you letters and year-end tax receipts by email, or print-ready for mail, with the right IRS language and proof of delivery.
Thank-yous sent · 48 donors tonight

Appeals & stewardship
Thank-yous that actually send.
Appeals and welcome journeys go out through Mango or Mailchimp. Unsubscribes are honored everywhere, and replies land with the right person.
Major gifts
Know where every ask stands.
A major-gift pipeline with next steps, owners and engagement scores, so no big conversation goes quiet.
The development agent
Know who needs a call.
Coffer's agent reconciles every gift, rescues failed monthly gifts, sends missing receipts, drafts stewardship from your own history and tracks retention donor by donor.
Move in
Bring every gift with you.
Move from Little Green Light, Bloomerang or Raiser's Edge NXT with every donor, household and gift, and check the totals before you switch.
