Flux gives foundations hosted donation fields, recurring giving, and the option to let donors cover the processing fee so more of each gift reaches the mission.
Why foundations 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 foundations get paid
Foundations 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 foundations
A foundation's incoming payments are few and large: contributions from founding families or corporate partners, pledge installments on multi-year commitments, and an annual benefit event. ACH carries the large gifts and settles in 1-3 business days; the gala runs on cards, with tickets and paddle raises settling in 1-2 business days. Because activity is lumpy, months can pass with no transactions at all, and with no monthly fees on qualifying card volume or minimums, quiet months cost nothing.
Foundations also move money out, and that is where payouts matter: instant payouts via Visa Direct can put an emergency grant or a scholarship disbursement on a recipient's eligible debit card in moments rather than mailing a check. The REST API lets program staff schedule disbursements against board-approved grant cycles, and every movement, in or out, syncs to QuickBooks so the auditor sees one ledger covering gifts, pledges, and grants paid.
What foundations should watch
Multi-year pledges are commitments, not cash, and the gap between the two is where foundation books go wrong. Schedule pledge installments as recurring ACH or card payments so collection is automatic rather than an annual awkward letter, and reconcile what actually arrived against the pledge schedule quarterly. When an installment fails, the development office should know that week: a missed payment caught early is a conversation, and one caught at audit time is a writedown.
Disbursements need controls more than speed: who approved the grant, which budget line it draws from, and proof the money went where the board directed. Run payouts through the API with your own approval step in front, and let the QuickBooks sync carry the transaction record into the books automatically. Speed still has its place, a hardship grant or disaster response benefits from Visa Direct, but the audit trail is the feature a foundation lives on.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume foundations 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.

How fast do foundations get their money?

Can we pay grants out through Flux, not just take money in?
Yes. Instant payouts via Visa Direct move funds to a recipient's eligible debit card in moments, which suits hardship grants and scholarships. Disbursements run through the same API and sync to QuickBooks alongside incoming gifts.
We only have a handful of transactions a year. Does an account make sense?
There are no monthly fees on qualifying card volume, minimums, or contracts, so a quiet account costs nothing to keep. You pay the flat per-transaction rate only when money actually moves, which fits a foundation's lumpy calendar.
Can we automate pledge installment collection?
Yes. Multi-year pledges can run as scheduled recurring ACH or card payments through the API, and failed installments surface immediately so development staff can follow up. That turns pledge collection from an annual letter into a background process.
