Tip-based platforms keep themselves free by asking your donors to tip the platform. Here’s what that can cost your mission.

On CharityStack

redirected to the platform. Optional tips go to your mission instead.
Where your donors’ generosity goes
Tip-based platform10% skimmed to the platform
CharityStack100% to your mission
That’s up to $50,000 a year of generosity that can support your mission instead of your software provider — up to 20% more donation value.
Illustrative estimate. Assumes donors cover processing fees about 88% of the time; CharityStack covers the rest.
Tips should support your mission, not your software provider.
Most “free” platforms make money by prompting your donors to tip them. CharityStack doesn’t.
