‍

What is Square?

Square is a large-scale financial services platform built to support small businesses. It was founded by Jack Dorsey and has grown into a widely used payment processing solution. Square processes billions of pounds in transactions annually and is a well-regarded option for collecting payments in person and online. The Square ecosystem includes mobile apps and card readers to turn a phone or tablet into a mobile point-of-sale system.

‍

Can charities use Square?

Charities can use Square to collect donations, even though the platform is primarily designed for businesses. It offers a straightforward way to process payments from supporters, particularly for organisations looking for flexible, easy-to-use tools without a complex setup.

It is important to be clear, however, that Square treats a charity as a merchant, not as a supporter-relationship tool. That distinction matters when it comes to Gift Aid, donor stewardship, and UK regulatory expectations. We cover the key donation-processing limitations, pros, and pricing considerations below.

‍

Where Square falls short for UK charities

Processing fees

Every card transaction through Square carries a processing fee. Square does not currently offer a charity-specific discount on processing fees, which is something many organisations weigh carefully when comparing platforms.

Some users note that fees require a closer look before committing:

"There are a lot of steps to set up new clients. Also, the fees are a bit on the high side." Michael L.

For UK charities, every percentage point redirected to fees is a pound that does not reach the cause. Some charities choose to explore platforms that offer alternative pricing models, especially if minimising fees is a top priority.

‍

Square does not handle Gift Aid

This is the most significant gap for UK registered charities. Via Gift Aid, your charity can reclaim 25p from HMRC for every £1 donated by a UK taxpayer, a £100 gift becomes £125 to your cause at no extra cost to the donor (HMRC Gift Aid guidance). To claim, you need a valid Gift Aid declaration from each donor (full name, home address, charity name, and confirmation they have paid sufficient UK tax), and you must keep those declarations for at least six years.

Square cannot collect a Gift Aid declaration or file a claim with HMRC Charities Online. A charity using Square must manage Gift Aid entirely outside the platform, through separate declaration forms, manual record-keeping, and manual submission to HMRC. Purpose-built UK charity platforms automate the declaration capture and the HMRC submission, saving small teams significant time and reducing the risk of a failed claim.

‍

No small society lottery support

If your charity runs a Christmas raffle or 50/50 draw, you will need to register a small society lottery with your local council (£40 initial fee, £20 annual renewal) under the Gambling Act 2005. Square handles the card payments for ticket sales, but it does not support the lottery registration, ticketing mechanics, or draw management. It is also worth noting that Gift Aid never applies to raffle ticket purchases, as the donor receives a chance to win (which constitutes goods or services in HMRC's view).

‍

Limited customer support

Square's support is delivered through phone, online chat, help articles, and self-service resources. Availability varies by plan, and free plans work with phone support within certain business hours. For time-sensitive fundraising issues, this can feel limiting. Some users report challenges navigating support channels:

"Tech support is terrible. First they will get into the retail vs web side of the house discussion, then once you get the right person, they never seem to know what features are or how to solve problems." John C.

‍

How much does Square cost UK charities?

Square's free plan makes it easy to begin accepting donations without upfront costs. However, understanding the full pricing structure, including processing fees and optional upgrades, helps clarify the real cost over time.

Square also offers paid plan upgrades for additional features (current UK pricing at squareup.com/gb, verified at time of publication).

‍

Square UK processing fees

Square does not currently offer discounted processing rates for charities. The following rates apply to UK transactions (source: Square UK pricing, verified 2026):

‍

‍

To put this in context: if your charity raises £10,000 at a fundraising event, with around 60% collected in person and 40% collected online via UK cards, Square's standard UK processing rates would result in approximately £165 in total fees. Your organisation would receive roughly £9,835 after fees. Over a year, that same fee structure could mean hundreds of pounds redirected away from your mission.

Crucially, this figure does not include what Gift Aid could add. On the portion of donations that are eligible (not raffle tickets, not event tickets at fair value), a specialist UK charity platform with Gift Aid handling would reclaim an additional 25p per £1 from HMRC. Square cannot deliver that uplift.

‍

‍

Square additional costs for UK charities

Beyond processing fees, some features within Square's ecosystem carry additional costs. Square Payroll is not currently available in the UK and should not be factored into your planning.

Hardware is available separately from Square's UK hardware page (squareup.com/gb/en/hardware, prices verified at time of publication):

‍

‍

A free Square Reader comes with your account. Additional hardware is optional and may not be necessary for every organisation.

Square Donation Fee Calculator

‍

Every charity's donation mix looks different. Use this calculator as an order-of-magnitude guide to estimate how fees may scale as your fundraising grows. Please note: this calculator uses US Square rates in US dollars. UK Square rates differ (see the fee table above), use it as a rough guide, then check against Square's current UK pricing at squareup.com/gb.

This estimate is based on Square's standard processing rates and illustrates how fees compound across a fundraising year.

‍

Evaluating Square for small UK charities

Square is designed primarily for small businesses, which means its features and workflows are not always tailored to charity fundraising. For some organisations, this may not be a barrier. For those with more complex donor-engagement needs, it can require additional tools or workarounds.

Here are the key considerations for small or grassroots UK charities:

• Not built for charities: Square treats donors as customers. There is no Gift Aid declaration capture, no Fundraising Regulator badge integration, and no field for campaign designation or giving frequency.

• No Gift Aid automation: The 25p-per-£1 HMRC reclaim must be managed entirely outside Square, adding manual work and risk of missed claims.

• Donor data structured as customer data: Square's customer directory does not distinguish donors from retail buyers. This creates real challenges under UK GDPR (the ICO's purpose-limitation principle) for donor stewardship, and a growing number of trustees ask "Are you GDPR compliant?" before adopting any new platform.

• Recurring giving is not Direct Debit: Square supports subscription-style recurring payments, but Direct Debit (via GoCardless or a purpose-built fundraising platform) accounts for around 31% of all UK charity donations and is the sector standard for regular giving. Square's recurring model does not deliver Direct Debit.

• Transparent but standard fees: Fees are clearly outlined but are not reduced for charitable use.

Many small UK charities carrying out fete ticketing, an autumn appeal, a Christmas raffle, and a sponsored event are currently paying three or four separate tools. Platforms built for UK charities can consolidate that stack, handle Gift Aid, and charge nothing.

‍

Square for UK charities: honest pros and cons

Square can be a practical payment solution for many organisations. Its business-first design does mean there are tradeoffs to consider for charity fundraising.

‍

‍

‍

Key Square features UK charities actually use

Square online donations

Square allows donations to be added as items on a website. Square Payment Links can also be shared with supporters to complete a transaction from any device.

UK payment options accepted:

• One-time credit and debit card payments

• ACH-equivalent bank transfers

• Apple Pay and Google Pay

• Clearpay (buy now, pay later, for merchandise or ticket sales)

Square allows donations to be set up similarly to products or services, making it possible to accept contributions through a website or shared payment link. This can work well for organisations looking for a simple way to launch donation collection quickly. Regular giving is available through Square payment links as a general-purpose subscription tool, but it is not built for the charity donor experience and does not support Direct Debit.

‍

In-person donations with Square Reader

Square's point-of-sale system enables charities to accept in-person payments at events, fetes, fundraisers, or other gatherings. Using mobile card readers or terminals, a charity can collect donations on-site and follow up with supporters through digital payment options.

This flexibility is genuinely useful as cash use continues to fall at community fundraising events. UK VoC research confirms the pain: small organisations like village halls and PTAs report that many supporters no longer carry cash, yet lack any card-payment infrastructure.

Square Reader addresses this need, but it comes with a hardware cost and a per-transaction fee. For dedicated contactless donation devices (such as fixed giving points at museums or visitor attractions), GoodBox is the UK specialist. For a completely free in-person option, Zeffy's Tap to Pay app lets supporters tap to pay directly from their phones without a card reader, at no cost to the charity.

‍

Donation settings

Charities can set up 'Donation Items' in Square with the following customisations:

• A title, description, and photo

• Suggested gift amounts

• Text modifiers for customisations such as donating in memory of someone

Funds can be transferred to the charity's bank account the next working day (free) or instantly (for a fee). That can be helpful when covering upfront event costs and needing donor revenue quickly.

‍

Square analytics

Square Analytics offers real-time insights through a simple dashboard, surfacing data around:

• Transactions from online donation forms

• Event registrations and ticket sales

• In-person donations through the Square Reader or point-of-sale app

• Recurring or membership gifts

• Payment details and card-expiry alerts

• Merchandise sales

• Revenue across fundraising activities

Staff and trustees can review how much was raised during a campaign or event, helping inform future planning.

‍

Supporter data collection

A charity using Square gains a customer directory that can be segmented by:

• Loyal or repeat supporters

• Passive supporters

• Lapsed donors

• Event attendees

Square's email and text templates help you reach different segments with relevant appeals. This can be useful for building a basic supporter database and segmenting major gift prospects.

Important to note: Square does not distinguish donors from customers. There is no field for donation intent, campaign designation, or giving frequency. Square's customer data tools are flexible, but they are built for general customer management rather than charity supporter stewardship.

‍

Automatic receipts and Gift Aid declarations

When a donation, registration, or merchandise purchase is made, Square automatically sends a confirmation email to the supporter. The confirmation includes basic transaction details:

• Item name

• Amount

• Payment method

• Your organisation's name and contact information

You can customise the receipt footer with a thank-you note or your HMRC charity reference number.

However, Square's automatic email confirmation is not a Gift Aid declaration. For a charity to reclaim 25p per £1 from HMRC, it needs a valid declaration from the donor: full name, home address, charity name, and confirmation that the donor is a UK taxpayer who has paid sufficient Income or Capital Gains Tax. That declaration must be kept for at least six years. Square does not collect these declarations or automate the HMRC claim.

For UK basic-rate donors, Gift Aid relief is claimed by the charity, not the donor, so there is no "tax receipt" mechanism in the UK sense. What matters is the declaration, and Square cannot provide it.

‍

‍

‍

Zeffy's built-in Gift Aid handling can save small teams significant time, especially during high-volume periods like Giving Tuesday or a year-end appeal.

‍

Fast transfers

With Square's standard transfers, charities can receive funds in their chosen bank account within one to two business days via Faster Payments.

Square also offers quicker transfer options for a fee:

• Instant transfers hit external bank accounts on demand, for a fee of 1.75% of the amount transferred.

• Same-day transfers hit external bank accounts on a scheduled basis, also for a fee of 1.75% of the amount transferred.

‍

Square integrations for UK charities

Square connects with a range of tools to support accounting, marketing, and website management. These integrations can help streamline workflows, though some may require third-party setup.

How Square compares to UK charity donation platforms

Some charities may find they need additional features or pricing structures more tailored to fundraising than Square can offer. Below, we compare Square with platforms used by UK charities to help you evaluate which option best fits your goals.

‍

How does Square compare to other UK charity donation platforms?

‍

Square or PayPal: which suits a UK charity better?

Both Square and PayPal are well-known options for collecting donations, but neither is tailored for UK charities. PayPal offers a reduced charity rate and the PayPal Giving Fund for registered charities, while Square excels with user-friendly tools for in-person card acceptance. Neither platform handles Gift Aid natively, which is the shared gap for any UK charity that relies on the 25p-per-£1 HMRC reclaim.

‍

What is the best payment processor for small UK charities?

If you are looking for a solution built specifically for charities, with features like event ticketing, supporter management, Gift Aid handling, and zero processing fees, platforms like Zeffy may offer a better fit for long-term growth.

‍

‍

Benefits of using Square for collecting donations

Flexible, easy-to-use interface

The simple app allows anyone on your team to use Square. A few taps help staff or volunteers collect donations, contact supporters, and manage donation activity. A free Square Reader comes with your account, with the option to purchase additional hardware as needed.

‍

Multiple ways to accept donations

Square gives supporters several ways to give, helping you capture donations whatever payment preference they have. Square currently supports:

• Credit and debit cards

• Bank account transfers

• Apple Pay and Google Pay

• Clearpay (buy now, pay later, for larger purchases)

• Cash and cheques for offline gifts

‍

Data and payment security

Card numbers, magnetic stripe data, and security codes are not stored on Square client devices. Square uses encryption and PCI-compliant processing throughout.

• Toggle on 'Set donation goal' and enter the amount you are aiming to raise and a deadline to create a sense of urgency

‍

Checklist: what to look for when choosing an online payment system

Your donors are not just customers but passionate supporters seeking a connection with a cause. Choosing an online payment system is about minimising friction in the donation experience while ensuring every pound possible reaches your mission. Consider the following when evaluating any platform:

Costs for your charity: Are you clear on transaction fees, plan fees, and the cost of any features you may need as you grow?

Ease of donation: Have you looked at the platform's donation experience through a donor's eyes? Can you create a donation form that completes transactions without friction?

Gift Aid handling: Does the platform capture Gift Aid declarations and automate the HMRC claim? For UK registered charities, this can add 25% to every eligible donation.

Branded experience: Do you have sufficient customisation options? Can you add custom questions and reflect your charity's identity throughout?

Supporter management and relationship building: Can you access donor information and transaction history in one place? Are there automatic emails triggered after a donation?

Diversified fundraising: Does the platform support peer-to-peer fundraising, event management, and regular giving? Is it easy to track and manage donations across campaigns?

Future growth: Can you embed your donation form on your website and social media channels?

‍

How to switch from Square to Zeffy

Small charities may want the simplicity of Square without any of the cost, and switching to Zeffy is straightforward. Start by creating a free Zeffy account at zeffy.com/en-gb/register and setting up your donation forms, events, or campaigns using Zeffy's charity-specific tools.

Once you are ready, update any donation links on your website, email newsletters, and social media to point to your new Zeffy pages. Let supporters know about the switch so they understand that 100% of their gift goes directly to your cause. Zeffy's support team is available to help with the transition if you need assistance.

‍

Square vs Zeffy for UK charities: which is better?

‍

Square charges processing fees on every transaction. Zeffy charges nothing, no platform fee, no transaction fee, no credit card fee, ever.

Beyond cost, Zeffy consolidates the tools many UK charities currently stitch together separately: Square for card payments, JustGiving for donate pages, Ticket Tailor for event ticketing, and a separate CRM. Zeffy brings donations, ticketing, raffles, memberships, auctions, and supporter management into one free platform, with Gift Aid handling and UK regulatory fit (including Fundraising Regulator compliance and small society lottery support).
