Why choose Zeffy over JustGiving and Mightycause if you're a nonprofit
💸
JustGiving and Mightycause take a cut before you see a dollar
JustGiving takes 5% off every donation and Mightycause charges 1.99% plus card fees. Zeffy covers all costs so your supporters' full gifts go to your mission, not platform fees.

📞
Zeffy gives you every tool you need to fundraise, 100% free
JustGiving's support runs on UK time with UK compliance guidance. Mightycause reserves phone support for paid subscribers. Zeffy's team answers fast during your hours and knows US nonprofit rules inside out.
