Let’s talk tipping.
Donor tipping shows up in checkout flows everywhere now, from the coffee shop to the dry cleaner, and fundraising platforms are no exception. Some nonprofits have found it workable. Others have watched it confuse and frustrate their donors. The difference usually comes down to how it’s implemented, not whether it’s used at all.
A growing number of fundraising platforms now offer tipping as one way to fund the software — alongside annual plans, volume-based processing fees, or some combination. None of those models is automatically the wrong choice. What matters is whether the fee structure is disclosed clearly, easy to adjust, and never mandatory.
If your donors have ever complained about unexpected charges at checkout, or if you’re evaluating a platform and trying to decode what “free” actually means, this guide breaks it down.
What Is Donor Tipping?
During the donation process, some fundraising platforms ask donors to add a voluntary “tip” to support the platform itself, not the nonprofit receiving the gift. The tipping model is most common among platforms that advertise as free to nonprofits, since the tip replaces the annual license or platform fee the organization would otherwise pay.
A few mechanics worth understanding before evaluating a platform that uses this model:
- Tips typically range from 10–19% of the donation amount, and they often default to a pre-selected percentage
- The tip goes to the software company, not to the cause the donor chose to support
- If a nonprofit turns off tipping on a platform that relies on it, the platform usually applies a separate fee to compensate
- Standard credit card processing fees (typically around 2–3% per transaction) are separate from tips and apply regardless of which pricing model a platform uses
The donor tipping model has grown more common as the “free fundraising software” category has expanded. The appeal is obvious: no upfront cost for the nonprofit, no barrier to getting started. The risk, just as obvious once you’ve seen it play out: donors fund the platform without always knowing they’re doing it.
How the Donor Tipping Model Works on Free Fundraising Platforms
A growing number of platforms now offer fundraising software at no upfront platform fee. Many use donor tipping as the primary revenue source that sustains the model.
In its simplest form: the platform is free to the nonprofit, and donors are invited, or prompted, to add a percentage at checkout to keep the platform running. The nonprofit doesn’t pay a platform license. The platform still gets paid. And the donor covers it.
The concept isn’t inherently problematic. Donors voluntarily contributing to operational costs isn’t unusual, especially when they understand what they’re doing. The problem is implementation. Many tipping-based platforms:
- By default, the tip is set to a high percentage (10, 15%, even higher), so most donors don’t notice or don’t change it
- Make the opt-out harder than it should be, burying the option in small print or requiring extra steps
- Present the tip in a way that makes it look like part of the donation total, leaving donors uncertain about where their money actually goes
- Layer the tip on top of processing fees, so donors face multiple add-ons before the transaction is complete
When those conditions are present: a high default, an unclear opt-out, no explanation of where the money goes — the result is confused donors, reduced trust, and added work for nonprofits trying to explain a third party’s fee structure to their own supporters.
Tipping fatigue is well-documented across consumer industries. It reaches donors at the worst possible moment: they’ve engaged with your story, connected with your mission, and are ready to give. An unexpected or confusing fee prompt right there can change their mind.
How Tipping Affects Donor Trust and Giving Behavior
Donor retention rates have steadily declined across the sector, making each giving moment count more. Poorly implemented tipping creates friction at the worst possible time.
Perceived Lack of Transparency
When a tip is set at a high default rate and isn’t easy to see or adjust, donors may feel the platform is capitalizing on their goodwill. The nonprofit bears the reputational risk — donors question how much of their gift actually reaches the cause they chose to support.
The Association of Fundraising Professionals (AFP) addressed this directly in its 2026 Nonprofit-First Considerations for Platforms Enabling Charitable Donations. Released in response to high-profile platform failures and growing donor concern, the framework notes: “Donors may not realize they are transacting with an independent platform rather than directly with a nonprofit. Funds may be delayed, reduced by undisclosed fees, or, in rare cases, lost entirely when platforms fail.” AFP’s Consideration 1 calls for fees to be disclosed “conspicuously and accessible, not buried in footnotes or obscured by complex language” — and for donors to have the ability to make an informed decision before completing their gift.
When tipping fails that standard, trust erodes in the platform and in the nonprofit using it.
Impact on Donation Decisions
High default tip percentages can prompt donors to reduce their gift to offset the added cost, or to abandon the checkout entirely. Donors aren’t opposed to covering reasonable costs when they understand what they’re covering. What generates friction is the feeling of being surprised or pushed into something they didn’t choose.
Nonprofits lose gifts this way — not because of their mission, but because of someone else’s checkout design.
Extra Work for Nonprofits
Tipping friction creates operational overhead. Nonprofits find themselves writing FAQs explaining a third party’s fee model, answering donor calls about charges they didn’t recognize, or proactively coaching their donors through a checkout process that shouldn’t require coaching.
Here’s how some nonprofits have described the experience:
“Sometimes it’s confusing for our users about what [platform] calls their tip. Users aren’t sure if that’s going to us (a nonprofit).”
“Didn’t like the automatic tipping set at either 12–15% of purchase. Some guests didn’t realize this was happening until after they purchased. Guests felt they were swindled into the tip.”
“We also did not like the Tips feature. We felt that this was confusing to our donors, who may not understand what [platform] is, and that those funds would not be included as part of their gift to our organization. We would instead prefer to have a flat platform fee.”
“Many donors have thought they were covering the processing fee, but they were actually ‘tipping’ [platform]. We shut that functionality off and pay the associated fees so our donors don’t have to deal with that. We think it feels wrong to donors when they give $1,000 and then are asked to add a $100 ‘tip’ to [platform].”
What these accounts share isn’t tipping itself — it’s that tipping wasn’t clearly explained, the default was too high, and the process left donors feeling deceived. That outcome is avoidable. It’s a function of how a platform implements the model, not the model itself.
Donor Tipping vs. Platform Fees: What’s the Real Difference?
Free vs. paid is the wrong frame. What actually matters is whether fees are disclosed or buried. Donor choice factors in, too.
| Tipping Done Poorly | Tipping Done Responsibly | Platform Processing Fee | |
| Who pays | Donor, often without realizing it | Donor, with full disclosure and control | Nonprofit or donor (if donor opts in to cover fees) |
| Default | Pre-set at 10–19% | Starts at $0 with clear opt-in | Fixed rate, disclosed at signup |
| Transparency | Often buried or unclear | Fully visible before checkout is complete | Clear from signup |
| Donor control | Opt-out is difficult or obscured | Easy to adjust or decline | N/A — separate cost the org absorbs |
| Budget predictability | Varies based on donor behavior | Varies based on donor behavior | Consistent — same rate every transaction |
| Donor perception | Frequently confusing or frustrating | Generally accepted when clearly explained | Standard; donors recognize processing fees |
The model that protects donors and nonprofits is consistent across all three structures: fees disclosed upfront, in plain language, before the donor completes the transaction, with the ability to adjust or opt out entirely. AFP’s Consideration 1 doesn’t specify which model platforms must use. It specifies that, whatever fees apply, donors must understand and act on that information before they give.
Standard credit card processing fees are a separate category entirely. These are charged by the card networks (Visa, Mastercard, Discover, American Express) and applied by every payment processor. Reputable platforms apply the same rate regardless of donation size or time of year, making them predictable and budgetable. Many platforms also give donors the option to voluntarily cover these fees, keeping more of the gift with the nonprofit without pressuring donors at checkout.
Signs Your Fundraising Platform’s Fee Model Needs a Second Look
If you’re evaluating a new platform or reviewing your current one, these signals suggest the fee structure may be creating problems you haven’t fully accounted for.
Your donors have complained about unexpected charges. If supporters have reached out confused about amounts they didn’t intend to give, or frustrated about where extra money went, that’s a sign you have a disclosure problem.
You can’t explain what your platform costs in two sentences. If the answer changes depending on whether tipping is on, how much donors raise, what time of year it is, or which features you’ve activated — that complexity will eventually surface at checkout, in your donors’ credit card statements, and in your own budget projections.
The opt-out process requires effort. A responsible fee model doesn’t require a donor to hunt for a “remove tip” button. If adjusting or declining a fee is harder than accepting it, it’s likely an intentional design, which should be a red flag.
You’re paying for things you didn’t expect. Some “free” platforms charge separately for features that matter: payment methods like Apple Pay, auction functionality, live support, or access to more than one active event at a time. The total cost of a platform includes all of those, not just the headline number.
You’ve had to write donor-facing communications about your platform’s fee structure. If you’ve drafted an email or FAQ explaining what the tipping prompt is and why it appears on your donation form, your organization has spent time and credibility managing someone else’s model. That’s worth factoring into your platform decision.
Choosing the Right Funding Model for Your Organization
Not every organization needs the same pricing model. The right structure depends on your fundraising volume, your budget, and what your donors are comfortable with. What matters is that you can explain the cost structure clearly — to yourself and to your donors.
Fixed annual plan: The organization pays an annual license fee, and software costs stay flat regardless of how much is raised. This is typically the most cost-effective structure for nonprofits with consistent, high-volume fundraising. It includes dedicated support, unlimited event access, and the full feature set. The cost is predictable, and donors never see it.
Pay-As-You-Go: No upfront platform fee. Instead, the platform is funded through a disclosed processing rate applied to each transaction. GiveSmart now offers this model as GiveSmart Pay-As-You-Go: a $0-license option with a clearly disclosed processing rate, available across both GiveSmart Events and GiveSmart Fundraise. It’s designed for newer or smaller organizations that aren’t ready to commit to an annual plan, and it works because the rate is disclosed before signup — no surprises at checkout for the organization or its donors.
Donor-covered contribution model: No license fee to the organization. Donors are presented with an optional suggested contribution to cover platform costs at checkout, with the option to adjust or decline entirely. In a responsible implementation, meeting the standard described in AFP’s Consideration 1, the contribution starts at $0, is clearly explained, and is never preset to an aggressive default. This model can work well for organizations with a mission-aligned donor base whose supporters are comfortable with the approach when it is done with full transparency.
Ask a better question than “Which model is cheapest?” Ask, “Can I tell my donors exactly what they’re being asked to cover, and do they have a genuine choice?” Any model can answer that honestly. The ones that can’t are the problem.
Fund Your Platform the Way That Works for You
There’s no single right funding model for every nonprofit. What works for a first-year organization running one auction a year looks different from what works for an established organization processing gifts through a major annual gala. The right answer depends on where you are, what your donors expect, and what gives you predictable costs.
GiveSmart gives you the choice: a fixed annual plan or Pay-As-You-Go, both on the same platform, with access to the same core tools and the same quality. Whichever model fits your organization right now, the costs are disclosed upfront—for you and your donors.

Frequently Asked Questions About Donor Tipping
What is donor tipping? Donor tipping is a model used by some fundraising platforms that prompts donors to add a percentage (typically 10–19% of their donation) to support the platform rather than the nonprofit they’re giving to. It often appears at checkout as a pre-selected default and functions as the platform’s revenue source in place of an annual license fee charged to the organization.
Is donor tipping ethical for nonprofits? Tipping isn’t inherently unethical. Implementation is what matters. AFP’s 2026 Nonprofit-First Considerations call on platforms to disclose all fees clearly and in plain language, before the donor completes the transaction, with amounts fully visible and easy to adjust or decline. Tipping that meets those standards is defensible. Tipping that defaults to high, obscuring the opt-out, or failing to explain where the money goes, erodes donor trust — and reflects on the nonprofit using the platform. The AFP’s Code of Ethical Standards, which covers member obligations around transparency and honest representation, provides the longer-standing professional baseline.
How much do free fundraising platforms typically charge in tips? Most tipping-based platforms default to a range of 10% to 19% of the donation amount. Donors can usually adjust this, but many don’t notice or change it before completing their transaction. Credit card processing fees are separate and apply on top of the tip.
Can nonprofits turn off donor tipping? Usually, yes. But if the platform relies on tipping as its primary revenue model, turning it off typically triggers a separate platform fee charged to the organization instead. Before turning off tipping, confirm what the fee structure looks like in both scenarios — on and off.
What’s the difference between a tip and a platform fee? A platform fee is paid by the nonprofit, typically as an annual license fee or a per-transaction processing rate, and doesn’t appear in the donor’s checkout at all. A tip is charged to the donor at checkout. Both fund the platform; the difference is who pays and how visibly. See the comparison table above for a full breakdown.
Do donors know where their tip money goes? Not always. In poorly implemented tipping models, the opt-in is pre-selected, and the explanation is minimal, leaving donors uncertain whether the tip reaches the nonprofit, goes to the platform, or covers some combination of costs. AFP’s 2026 guidelines call for platforms to clearly explain who receives each fee and for what purpose, before the donor completes the transaction. When that standard is met, most donors make informed choices. When it isn’t, the confusion falls on the nonprofit. and elevate your fundraising.
