Flux gives charities hosted donation fields, recurring giving, and the option to let donors cover the processing fee so more of each gift reaches the mission.
Why charities choose Flux
Recurring giving
Turn one-time donors into monthly supporters with automatic recurring gifts.
Donors can cover the fee
Where local rules allow, donors can add the processing fee so more of the gift lands.
Low overhead
No setup fees or contracts, so more of every dollar goes to the work.
How charities get paid
Charities take one-time and recurring gifts by card, accept ACH for larger donations, and can let donors cover the fee at checkout where allowed.
A typical Flux setup for charities
Charity revenue is appeal-driven: a mail or email campaign lands, and a wave of small card gifts follows within days. Hosted fields on the donation page take the volume at a flat 2.9% plus 30 cents with no tiers to outgrow mid-campaign, and card gifts settle in 1-2 business days, which keeps cash arriving while the appeal is still running. Monthly sustainers convert from those one-time givers and run as recurring card or ACH payments.
When a disaster response appeal goes live, giving compresses into hours, not weeks. Stablecoin gifts on Solana or Ripple settle to your wallet instantly, which matters when relief spending starts before card settlement lands. The REST API lets your team spin up campaign-specific checkout flows and peer-to-peer fundraiser pages without waiting on a processor, and instant payouts via Visa Direct move funds out when field teams need them.
What charities should watch
High-visibility donation forms are a favorite target for card testing, and an emergency appeal makes the pattern worse because a burst of small gifts looks normal. Hosted fields in origin-isolated iframes mean tested numbers never touch your servers, and SAQ-D Level 2 PCI DSS compliance sits with Flux rather than your web team. Still, monitor for runs of identical amounts from sequential attempts and refund confirmed test charges quickly to limit disputes.
Emotional giving produces honest mistakes: duplicate submissions, a misplaced decimal, a donor who overcommitted. Refund these without friction; a donor who gets a fast refund gives again, and one who files a chargeback rarely does. Sustainer programs also churn as cards expire, so watch failed recurring gifts and re-invite lapsed sustainers by email rather than silently retrying. Clean dispute hygiene protects the account every future appeal depends on.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume charities and the option to pass the fee to the customer at checkout where local surcharging rules allow. No setup fees and no contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee.
Frequently asked questions
How do charities accept payments with Flux?
Charities accept credit and debit cards, ACH bank transfers, and stablecoins through one Flux integration, with drop-in hosted fields that keep card data off your own systems.
What does Flux charge charities?
A flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume merchants and no setup fees or contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee. You can also pass the processing fee to the customer at checkout where local surcharging rules allow.
How fast do charities get their money?
Card payments settle in one to two business days and ACH in one to three business days. Stablecoin payments go to your wallet instantly.
Can supporters overseas donate to our charity?
Stablecoin donations give overseas supporters a direct route: gifts on Solana or Ripple (XRP Ledger) settle to your wallet instantly. Your donation page can offer that option alongside cards through the same API.
What happens if we get a surge of gifts during an emergency appeal?
Nothing changes about your terms: the flat 2.9% plus 30 cents applies at any volume, with no tier to renegotiate mid-crisis, and card gifts keep settling in 1-2 business days. If the higher volume is sustained, custom interchange-plus pricing is available.
A donor gave twice by mistake. How do refunds work?
Refunds are a single API call against the original gift, full or partial. Returning a duplicate quickly usually heads off a chargeback, which is worth far more to the charity than the gift retained.
