If you’re running a nonprofit, you already know that every dollar counts, and every donor interaction matters.
When it comes to accepting donations, having the right payment processing platform makes a huge difference. A lot of nonprofits use Square because it’s well known and easy to get started with. But over time, many organizations realize it doesn’t always fit their needs as they grow.
You might be looking for something that’s built more for fundraising. Or maybe you’re tired of high transaction fees, clunky tools, or limited support. Whatever the reason, you're not alone, many nonprofits are searching for alternatives that do more than just swipe cards.

Why nonprofits are seeking better payment processors in 2026
When Square first hit the scene, it felt like a game-changer. It was simple, fast, and gave nonprofits a way to accept donations in person without a bunch of setup. But fast forward to today, and things have changed. Nonprofits need more than just a way to take payments, they need tools that support long-term fundraising, deeper donor relationships, and better data.
One of the biggest pain points? Fees. Square charges 2.6% plus 10¢ per transaction. That might not sound like a lot, but over time, especially with high-volume or recurring donors, those fees add up. And unlike some platforms, Square doesn’t offer nonprofit-specific discounts or features built for fundraising campaigns.
Another challenge is flexibility. Square is great for selling merchandise or tickets at an event, but it’s not built with donation pages, recurring giving, or donor engagement in mind. You can plug in workarounds, but that takes extra time, time most nonprofit teams don’t have.
That’s why more and more organizations are looking for payment processing solutions made with them in mind. Ones that can handle online and in-person donations, offer helpful features like donor profiles and recurring gifts, and actually make their work easier.
What makes a great nonprofit payment processing platform
Not all payment platforms are built the same. What works for a retail store isn’t always the best fit for a nonprofit. When you’re choosing a solution to help you collect donations, it’s not just about taking a credit card. You need a tool that works with you, not just for you.
First, look at the fees. A lot of platforms charge around 2.2% to 2.9% plus 30¢ per transaction. Some even add monthly fees on top of that. For small or growing nonprofits, that can be a dealbreaker. The best processors offer fair pricing, and some even give discounts just for nonprofits.
Next, think about how people give. Donors want quick, easy options, credit cards, Apple Pay, Google Pay, and even mobile giving. A good platform will accept all of these without making donors jump through hoops.
But it doesn’t stop there. Great platforms also let you:
- Set up custom donation pages that match your brand
- Offer recurring donations
- Track donor history and behavior
- See real-time data and trends
- Connect to your CRM or email tools
- Stay secure and compliant with donation info
It’s about more than processing payments, it’s about growing your mission with tools that are made for fundraising.
Top Square alternatives for nonprofits
There’s no shortage of payment platforms out there, but not all of them truly understand what nonprofits need. Below are the top Square alternatives that go beyond basic payment processing. Each one brings something different to the table, whether it's lower fees, better donor tools, or features made just for fundraising.
1. Bloomerang Payments: Best for unified donation management
Bloomerang Payments combines donation processing with built-in donor management, so you’re not juggling multiple systems. It’s designed specifically for nonprofits, which means things like recurring donations, branded donation forms, and tracking donor engagement are baked in, not added on later.
You also get access to a powerful CRM, making it easier to build stronger relationships and raise more over time. If your team wants an all-in-one solution that feels like it was made just for fundraisers, this one’s a solid pick.
2. Stripe: Best payment gateway for tech-savvy nonprofits
Stripe is flexible and developer-friendly, making it a great option if you’ve got someone on your team who’s comfortable with integrations and customizations. It supports credit cards, ACH, Apple Pay, Google Pay, and more.
While Stripe wasn’t built just for nonprofits, its tools are powerful, and it offers discounted rates to eligible organizations. You’ll need a bit more setup time, but you’ll get a sleek, professional experience in return.
3. PayPal: Best for startup and small-budget nonprofits
PayPal is easy to use, widely trusted, and quick to set up. For small nonprofits or brand-new organizations, it’s a simple way to start collecting donations without a ton of overhead.
It supports recurring donations and can be added to almost any website with just a few clicks. However, it’s not as feature-rich when it comes to fundraising strategy or donor tracking, so it works best as a stepping stone or backup option.
4. Clover: Best for in-person donations and events
If your nonprofit raises money through events, booths, or a physical location, Clover offers solid point-of-sale tools. You can take payments with cards, mobile wallets, or contactless tap, just like a retail setup.
It’s great for quick transactions and in-person engagement, but it doesn’t offer deep donor features like recurring giving or branded donation forms. Think of it as a strong in-person companion rather than a full fundraising system.
5. Donorbox: Best for optimizing donation pages
Donorbox focuses on helping you build beautiful, high-converting donation pages. It’s great at turning visitors into recurring donors with options like one-click giving, customizable forms, and progress trackers.
You can also plug Donorbox into your existing site or fundraising campaigns without much hassle. If your priority is online donations and you want to improve the donor experience, this one’s worth checking out.
6. Helcim: Best low-fee processor with no monthly fee
Helcim is all about transparency. There are no monthly fees, and the rates are often lower than big-name competitors. You only pay for what you use, and their pricing calculator makes it easy to estimate your costs.
It’s not designed just for nonprofits, but its clear pricing and helpful tools make it a strong choice for organizations that want to save money while keeping donations simple and secure.
7. iATS Payments: Best for CRM integration
iATS was built with nonprofits in mind, and it shows. It’s especially powerful for organizations using CRMs like Salesforce. It handles recurring donations, integrates with fundraising tools, and helps reduce donor churn.
If your team is already using a donor database or needs a more connected system, iATS can help everything work better together.
8. Authorize.net: Best for secure online payment acceptance
Authorize.net is a trusted name in online payments and offers strong security features that help protect donor data. It works well for nonprofits that need a reliable gateway and want to accept donations online, by phone, or even in person.
You’ll get flexible features, but you may need a bit more technical know-how to get the most out of it.
Comparison table: Square vs leading alternatives
It’s one thing to read about features. It’s another to see them side by side. Below is a quick comparison to help you weigh the options based on what matters most, fees, features, and how well each platform supports the way your nonprofit accepts payments.
This table doesn’t cover every feature, but it gives you a solid head start. Think about your priorities, like in-person donations, CRM needs, or fee savings, and you’ll be one step closer to finding the right fit.
How to choose the right Square alternative for your nonprofit
Every nonprofit is different. What works great for one team might feel totally off for another. That’s why choosing the right payment processing platform isn’t just about picking the “best” one, it’s about picking the one that works best for you.
Start with your size and setup. Are you a small team just starting out? Or a more established organization that needs custom tools and integrations? Some platforms are better suited for early-stage nonprofits (like PayPal or Donorbox), while others shine when you’re ready to scale (like Bloomerang or iATS).
Think about where you’re collecting donations. If you raise most of your money at events or in-person drives, look for strong point of sale features like Clover or Helcim. If your donors mostly give online, Stripe, Donorbox, or Harness might be a better match.
Look at the donor experience. Can someone give easily from their phone? Can they set up monthly donations without any trouble? Do your forms feel clean and trustworthy? You want tools that make giving simple, and that keep people coming back.
Consider your team’s time and tech skills. Platforms like Stripe offer tons of flexibility, but you might need developer help. Others, like Harness or Bloomerang, come ready to go out of the box.
And of course, always check the fine print. Fees, support, contract terms, those details matter more than you think.
At the end of the day, the right platform should do more than process payments. It should help you raise more, engage your donors better, and make your team’s life easier.
A nonprofit-first alternative to Square
