Not every campaign needs reward tiers. Donation-style campaigns take contributions of any amount, pay out to the fundraiser directly, and keep every rupee of your platform fee with you.

A campaign can run with no reward tiers at all. Backers enter the amount they want to give and check out on your domain. The same pledge pipeline handles it, so donation and reward campaigns coexist on one platform.
Donation campaigns usually want every contribution regardless of whether a goal is met. Flexible funding does exactly that — funds are captured as they come in rather than held until a deadline.
Money moves through Stripe Connect into the fundraiser's own Stripe account. You are never holding other people's donations in your own balance, which keeps the arrangement simple.
Submitted campaigns land in an admin queue where you approve, reject with a note, or suspend. Optional automated screening flags thin or mismatched submissions so you know which to read first.
A live install with real campaigns, or the full pricing breakdown — whichever you need first.
