Picking the wrong donation platform can hemorrhage money in hidden fees, lose donors to clunky checkout flows, or leave you without critical reporting tools when grant season hits. The difference between a platform that serves your nonprofit well and one that drains resources often comes down to asking the right questions upfront. Here's what to evaluate before you sign that contract.
Transaction Fees: What You'll Actually Pay
Most donation platforms charge between 1.5% and 3.5% per transaction, plus a fixed fee of $0.30 to $1.00. That percentage directly reduces what reaches your mission—a seemingly small 2.2% difference can cost thousands annually on a $100K fundraising goal. Ask providers for their exact fee structure in writing, including whether they charge differently for:
- One-time gifts vs. recurring donations
- Credit card vs. ACH bank transfers
- International donations (if applicable)
- Refunds or chargebacks
Request a sample cost breakdown on a $50 gift and a $5,000 grant to see real dollars. Don't let "competitive rates" be the answer—demand specifics.
Payment Methods and Flexibility
Donors have preferences. Some give via credit card at 11 PM on impulse; others prefer ACH for tax purposes. Ask whether the platform supports:
- All major credit cards, Apple Pay, Google Pay
- ACH direct debit transfers
- PayPal and Stripe integrations
- International payment methods (if relevant)
- Cryptocurrency (increasingly expected by younger donors)
A platform that only accepts Visa and Mastercard will cost you gifts. Check if they handle mobile optimization too—roughly 65% of online donations now come from phones, so a clunky mobile checkout is a dealbreaker.
Reporting and Donor Data Access
You need real-time visibility into who gave, what they gave, and when—especially for donor stewardship and grant reports. Ask:
- Can you export donor data and donation history at any time in standard formats (CSV, Excel)?
- Do you get live dashboards showing daily/monthly giving trends?
- Are there customizable reports for board meetings, grant applications, or tax documentation?
- How long does historical data stay accessible if you leave?
If the platform locks you into their interface or charges per report, walk away. Tools like Mercoly help you compare and find trusted donation platforms in one place, so you can see exactly what reporting capabilities each provider offers before committing.
Integration and Technical Requirements
Your donation platform doesn't live in isolation—it needs to talk to your CRM, email marketing tool, and accounting software. Confirm integrations with:
- Salesforce, HubSpot, or your existing donor database
- Mailchimp, Constant Contact, or your email platform
- QuickBooks, Xero, or your accounting system
- Your website CMS (WordPress, Drupal, Shopify, etc.)
Ask about API access too. If you want custom workflows or features down the road, a platform with solid API documentation prevents vendor lock-in. Setup time varies wildly—some take 30 minutes, others take weeks. Get a realistic timeline in writing.
Support, Training, and Transition
Platforms fail when staff don't know how to use them. Clarify:
- What training is included (video library, live onboarding, dedicated account manager)?
- Is support 24/7 or business hours only?
- How long is typical response time for issues?
- What happens to your data if you want to switch platforms later?
Ask about transition assistance explicitly. If a provider makes it easy to export your donor list and payment history, that's a green flag—they're confident in their service.
Compliance and Security
Nonprofits handle sensitive financial and personal data. Verify the platform is:
- PCI DSS Level 1 compliant (the gold standard for payment security)
- GDPR-compliant if you have international donors
- SOC 2 Type II certified
- Using HTTPS encryption and regular security audits
Request their security documentation and ask when their last audit was. Don't accept "we're secure" as an answer.
Frequently Asked Questions
Q: What's a reasonable contract term for a donation platform, and can I exit early? Most providers offer annual contracts with 30- to 90-day cancellation clauses. Avoid multiyear deals until you've tested the platform for at least three months—you need real fundraising seasons to evaluate fit.
Q: Will switching platforms mid-year lose donor records or payment history? No, if the provider supports data export. Always confirm in writing that you can download complete donor and transaction history in exportable formats before signing.
Q: How much should a nonprofit budget for a donation platform annually? Budget for transaction fees (1.5%–3.5% of gifts) plus monthly platform fees ($0–$500 depending on features and donor volume). A nonprofit raising $250K annually should expect $4K–$12K in platform costs combined.
Start asking these questions before any demo call, and you'll find a platform that actually serves your nonprofit, not the other way around.
