Flux gives nonprofits hosted donation fields, recurring giving, and the option to let donors cover the processing fee so more of each gift reaches the mission.
Why nonprofits 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 nonprofits get paid
Nonprofits 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 nonprofits
Most gifts arrive as card-not-present donations through your website, so hosted fields sit on the donation page and recurring monthly giving runs on the same flat 2.9% plus 30 cents rate. Major gifts and grant payments move by ACH, which suits five-figure amounts and settles in 1-3 business days. December carries an outsized share of the year's revenue, and settlement timing stays the same through the surge: cards in 1-2 business days, no volume minimums to renegotiate.
Event revenue behaves differently: gala tickets and auction checkouts cluster in a single night, paid by card in person or online, and settle within 1-2 business days. Every transaction syncs to QuickBooks so the bookkeeper can code gifts to the correct fund or campaign rather than re-keying a month of donations. Donors who hold stablecoins can give on Solana or Ripple, and those gifts settle to your wallet instantly, which matters during time-boxed matching campaigns.
What nonprofits should watch
Because nearly every gift is card-not-present, donation forms attract card testing: fraudsters run stolen numbers through small gifts to see which ones work. Hosted fields in origin-isolated iframes keep card data off your servers, so a probe of your site never touches a card number, and Flux's SAQ-D Level 2 PCI DSS posture is doing the compliance work instead of your staff. Watch your form for bursts of identical small gifts and refund them promptly.
Donor disputes are rare but real: a spouse who does not recognize the charge, or a monthly gift someone forgot to cancel. A fast, no-questions refund policy usually costs less than a chargeback, and the API makes refunds a single call. Recurring gifts also decay as cards expire, so pull declined-payment data from the API monthly and have a person, not a form letter, reach out. Lapsed donors respond to people.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume nonprofits 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 nonprofits accept payments with Flux?
Nonprofits 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 nonprofits?
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 nonprofits 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 donors choose to cover the processing fee on their gift?
Yes. Where local surcharging rules allow, the consumer pass-through option lets the fee ride on the donor's payment, and donation pages usually present it as an optional box the donor ticks. Where rules do not allow it, the flat 2.9% plus 30 cents simply comes out of the gift.
Can a major donor give by bank transfer instead of card?
Yes. ACH handles large gifts well and settles in 1-3 business days, with no separate fee schedule to negotiate. Your development office can collect pledge installments and grant payments the same way through the API.
How do we keep restricted and unrestricted gifts straight in our books?
Every transaction syncs to QuickBooks, so your bookkeeper can code gifts to funds and campaigns in the system your auditor already reads. The sync carries the transaction detail; the fund accounting judgment stays with your team, where it belongs.
