Donation processing for nonprofits.

Donation processing is how a nonprofit accepts gifts by card or bank transfer, online, by recurring charge and in person at events. A good setup keeps fees visible, makes monthly giving easy and protects your online form from fraud.

This guide covers each channel, how donor-covered fees work, and the card-testing problem that hits many donation pages. For pricing and setup across your organization, see our page on nonprofit card processing.

The three ways donors give

Channel	How it works	What to watch
Online donation form	Donor enters a card or bank account on your website through a secure gateway	Card testing, form friction, card-not-present costs
Recurring gifts	Donor’s card or bank account is charged on a set schedule	Expired cards, clear consent, easy cancellation
Events and in person	Mobile or countertop terminal at galas, auctions and drives	Wi-Fi or cellular signal, quick checkout
Mail and phone	Staff enters the gift in a virtual terminal	Keyed-entry costs, secure handling of card details

Most organizations use all of them. The goal is one processing account that handles every channel, so reporting and reconciliation happen in one place.

Online donation forms

Your donation page is your main fundraising tool. Keep it short and secure:

• Ask only for what you need: amount, name, email, card or bank details and billing ZIP code.
• Offer preset amounts and a custom amount.
• Offer a monthly option right on the form.
• Use a gateway with hosted payment fields, so card numbers go straight to the gateway and never touch your web server. That also shrinks your PCI scope.
• Send an immediate email receipt with the gift amount and your organization’s details. Ask your accountant what your receipts need to include.

Online gifts are card-not-present transactions, which generally carry higher interchange than a chip or tap in person. Card brands also publish interchange categories for qualifying charities. Whether your organization qualifies depends on its status and registration, so ask your processor to check rather than assuming.

Recurring gifts

Monthly donors are the steadiest income many nonprofits have. Recurring billing charges the donor’s card or bank account on the same day each month until they stop.

1. Get clear consent. Show the amount, the schedule and how to cancel before the donor submits.
2. Store the card as a token. Your systems keep a token, not the card number.
3. Plan for expired cards. Ask your processor about account updater services that refresh card details when a card is reissued.
4. Make cancelling easy. A donor who can’t cancel will dispute the charge instead, and that costs you more.

For larger monthly gifts, ACH from a bank account usually costs less than a card and does not expire. Our guide to recurring billing covers the setup in more detail.

Letting donors cover the fee

Many donation forms include a checkbox like “Add $1.85 to cover processing costs.” This is a voluntary gift on top of the donation. It is not a surcharge, because the donor chooses it and can leave it unchecked.

Keep it honest:

• Make it optional. Don’t pre-check the box without clear disclosure.
• Show the extra amount in dollars.
• Count it as part of the gift on the receipt, unless your accountant advises otherwise.

A true credit card surcharge is a different thing, with card-brand rules, a cap and disclosure requirements, and surcharges are never allowed on debit cards. Most nonprofits avoid surcharging gifts. If you are considering it, read our guide to surcharging rules and check current rules first.

Stopping card testing on your donation form

Donation forms are a favorite target for card testing. Fraudsters run hundreds of stolen card numbers through small donations to see which ones work. You pay a fee on every attempt, approved or not, and you may face disputes later.

Warning signs include a burst of small gifts from unfamiliar names, many declines in a short window and gifts from far outside your usual area. To prevent it:

• Add a CAPTCHA or bot check to the form.
• Set a minimum gift amount.
• Require CVV and billing ZIP, and turn on address verification.
• Ask your gateway to limit attempts per hour and per IP address.
• Review gateway reports weekly, and refund suspicious gifts quickly.

Our guide to card fraud prevention covers more of these controls.

Events, galas and auctions

Mobile terminals let volunteers take gifts and auction payments anywhere in the room. Test the signal in the venue before the event, charge batteries and make sure each device closes its batch at the end of the night.

Reporting and reconciliation

Gifts arrive from several places: the website, recurring charges, event terminals and the phone. If each channel runs through a different provider, your finance team has to stitch deposits together by hand every month. One processing account with clear reporting by channel makes it easier to match deposits to gifts, spot failed recurring charges and send accurate year-end statements to donors. Ask whether your processor’s reports can be exported to the donor database or accounting software you already use.

What PayZoom does

PayZoom works with nonprofits on online giving, recurring gifts, ACH and mobile terminals for events. We set up processing to fit the donation platform, gateway or cart you already use, and we don’t sell proprietary software. We recommend Interchange-Plus pricing, and for Interchange-Plus merchants our margin above interchange never increases, in writing.
