How It Works

Understanding how donation processing works requires knowledge of the broader payment ecosystem. The payment processing chain involves multiple parties, each playing a distinct role in every transaction.

The Payment Processing Chain

Every card transaction passes through several intermediaries before the funds reach the organization. The card networks (Visa, Mastercard, American Express, Discover) set the baseline interchange rates. These rates are non-negotiable and represent a large component of processing costs. On top of interchange, processors add their markup. Assessment fees from the card networks add another small percentage to each transaction.

The Merchant of Record Model

One model in payment processing is the Merchant of Record (MoR) model. In this setup, the payment provider becomes the seller of record for transactions. This means they are responsible for handling sales tax or VAT compliance. Organizations using an MoR still need to manage transaction disputes and are typically responsible for any associated dispute fees from the payment processor.

Best Practices

This guide's research has revealed several best practices that consistently lead to better outcomes for donation processing campaigns.

Essential Best Practices

Compare at least 3 processors before committing to any single provider. Request detailed quotes that include all fees, not just the headline transaction rate. Many processors advertise low per-transaction rates but add other costs.
Read the full agreement carefully and watch for early termination fees, automatic rate increases, monthly minimums, and long-term contract requirements. Look for providers that operate on month-to-month terms with no cancellation penalties.
Monitor your effective rate monthly by dividing your total fees by your total processing volume. If your rate seems high, you should explore alternatives.
Leverage your volume for better rates as your campaign grows. Once you reach a significant monthly volume, you may have negotiating power.

Advanced Optimization Strategies

Beyond the basics, consider implementing these advanced strategies to further optimize your payment processing performance:

Offer multiple payment methods to improve the donor experience. Allowing donors to contribute in their preferred way can increase completed donations.
Optimize for mobile payments since many online transactions now occur on mobile devices. Ensure your donation page is optimized for smaller screens and supports digital wallet payments.
Implement smart retry logic for declined transactions. Some processors automatically retry declined transactions, which can help recover donations that would otherwise be lost.

Provider	Monthly Fee	Transaction Fee	Payout Speed
Stripe	$0	2.7% + $0.30	2 days
PayPal	$0	3.49% + $0.49	1-3 days
Braintree	$0	2.59% + $0.49	2-3 days
Square	$0	2.6% + $0.10	1-2 days
Whop	None	2.7% + $0.30	Next-day (ACH)

Common Mistakes to Avoid

Avoiding common pitfalls is just as important as implementing best practices when it comes to donation processing for online campaigns. Here are the most costly mistakes organizations make repeatedly.

Contract and Pricing Mistakes

Signing long-term contracts with early termination fees: Month-to-month agreements are a common industry standard. Any processor requiring a multi-year commitment with hefty cancellation penalties may not be operating in your best interest. Modern processors often offer month-to-month terms.
Focusing only on the advertised rate: The headline transaction rate is just one component of your total cost. Factor in all monthly fees and other charges to calculate your true effective rate.
Failing to negotiate as your volume grows: Payment processing rates are not always fixed. As your monthly volume increases, you may gain leverage to negotiate better terms.

Operational Mistakes

Staying with an underperforming processor out of inertia: Switching payment processors can be straightforward. The fear of disruption keeps many organizations from seeking better solutions.
Overlooking payout speed: The difference between various payout speeds can have a massive impact on your cash flow. Faster access to your funds means better ability to manage your campaign's financial health.
Ignoring fraud prevention: Chargebacks can be costly. Investing in proper fraud prevention tools and working with a processor that offers robust fraud protection can save significant money over time.
