Which Is Better for Sole Traders and Micro-Businesses?
The main question is whether your card payments are regular or occasional.
Square works best when your card takings are unpredictable. You buy the reader for £19, connect it to your existing bank account, and pay no monthly fee. Your money usually arrives by the next working day.
That matters for sole traders who only take card payments now and again. With Square, there is no standing cost in quiet weeks. You only pay a transaction fee when a customer actually pays you.
The Tide reader only earns its place once your payments are steady. Before you take a penny, it asks for a Tide account, £99 for the hardware, and three working days to clear your money unless you pay £2.99 a month to speed it up.
For occasional takings, that is a lot to commit to for a slightly lower rate.
Square vs Tide Card Reader Fees and Charges
Card Transaction Fees
Square charges one rate: 1.75% on every in-person card. Amex and premium cards are included, with nothing added for the card type.
Tide looks cheaper on paper. It charges 1.39% + 5p with no plan, or 0.79% + 3p for debit on the Sell In-Person plan.
But the low rate comes with two catches. It is locked behind a monthly fee, and Tide does not take American Express at all.
We took both rates from the providers’ own pricing pages, not a comparison site, because published card rates move.
Monthly, Setup and Contract Costs
Square has no monthly fee on its base plan. The reader is a one-off £19. Trade nothing in a given month and you owe nothing.
Tide’s best rate needs the Sell In-Person plan, at £17.99 plus VAT a month. The reader is £99 with the plan, or £159 without.
That plan fee rose from £12.99 in April 2026, so budget at the current price.
Neither ties you to a long contract. The real commitment with Tide is the account itself, which you have to open and run.
Other Fees to Watch
Tide settles in three working days as standard. Next-day money costs an extra £2.99 plus VAT a month.
So the genuinely fast version of the plan is closer to £21 a month than the £17.99 on the label. We count it that way because the speed is a separate add-on.
Square’s only optional cost is the 1.5% instant transfer. Next business day is free, and neither charges you to set up or to leave.
Fee Verdict: Who Costs Less
At low or irregular volume, Square is cheaper once you add up Tide’s plan fee and hardware. Its flat rate is higher per tap, but nothing drags on a quiet month.
Tide only pulls ahead above roughly 130 payments a month at a £20 average. We ran the comparison across a range of monthly takings to find that line.
Below it, you are paying a subscription to reach a rate you cannot yet use.
Square vs Tide Card Reader Payment Methods and Checkout Options
Cards, Wallets and Alternative Payment Methods
On the everyday methods, the two are level: chip and PIN, contactless, Apple Pay, Google Pay.
The difference is American Express. Square takes it at the standard 1.75%. The Tide reader does not take it at all.
If even a few of your customers pay on a corporate or premium Amex, that is a steady trickle of sales Tide cannot process. We would not put it in an Amex-heavy business.
Checkout Experience
Square comes with a hosted checkout, a free online store, and payment links you can send while a customer is still in front of you.
Tide offers in-app payment links and invoicing, and little else. Anything you sell online has to live somewhere other than Tide.
That is fine for now. It becomes a problem the day web sales start to matter.
Methods Verdict
In person, there is little between them apart from Amex.
Online, Square is in a different class. It is built to run a shop; Tide is built only to take a payment.
Square vs Tide Card Reader Hardware, POS and In-Person Payments
Card Readers and Terminals
Square sells three devices you own outright: the £19 Reader for phone-paired payments, a £149 Terminal with a printer, and a £99 Stand for an iPad till.
Tide’s reader is a neat 4-inch touchscreen, £99 with the plan, with a £119 model that prints receipts.
It is good hardware. But it only ever connects to a Tide account.
POS Software and Hardware Add-ons
Square’s free app runs stock, staff, takings and a customer list. It scales up into a full retail or restaurant till.
For a business that needs more than a card machine, that software, included at no cost, is the strongest reason to choose Square.
Tide’s till software is much thinner: no table plans, no kitchen display, no barcode stock control. It takes a payment cleanly, but it will not run a busy floor.
In-Person Verdict
For the counter, Square gives you a cheaper reader and a far more capable free till.
Tide’s reader is a sound payment device but a basic point of sale. On both counts, Square is ahead.
Square vs Tide Card Reader Online Payments and Integrations
Hosted Checkout, Payment Links and APIs
Square gives you a hosted checkout, payment links, and a documented API a developer can build into your own site.
Tide offers in-app links and invoicing only. There is no public API and no store builder.
Platform Integrations
Square connects to WooCommerce, Wix, Xero and QuickBooks.
Tide syncs cleanly with Xero, QuickBooks and Making Tax Digital through its banking. That is genuinely useful if your books already sit inside Tide.
Online Verdict
If any part of your trade happens on a website, Square wins outright.
Tide’s strength is keeping a Tide customer’s books tidy, not selling online.
Square vs Tide Card Reader Payouts, Contract Terms and Account Risk
Settlement Speed and Payout Schedule
Square pays out the next business day, free.
Tide is slower by default, at three working days. It charges £2.99 plus VAT a month just to match Square’s next-day speed.
If you run close to your bank balance, that lag matters. Money from a Saturday’s trade that does not arrive until Wednesday can be the difference between paying a supplier on time and putting them off.
Contract Length and Exit Terms
Both run on rolling monthly terms, with no long lock-in.
The catch with Tide is not the contract. It is the dependency: close the Tide account and the reader stops working the same day.
Reserves, Holds and Account Stability
Both providers can freeze your money, and this part is worth reading twice.
Square can hold funds for up to 30 days when its system flags a sudden spike or an unusually large sale. It releases them once you show invoices or proof of delivery.
Tide’s version runs deeper, because the reader sits inside the bank account. A compliance review on the account freezes your card takings at the same time. One flag can stop everything.
We would hold a cash buffer with either, but more so with Tide. Try not to run every payment through a single linked account.
Square vs Tide Card Reader Customer Reviews and Reputation
Trustpilot and Independent Review Themes
Square holds 4.1 out of 5 on Trustpilot, across more than 3,600 reviews. It is well rated for onboarding and payouts, and marked down for held funds.
We put more weight on the recent reviews than the headline score, because early onboarding praise ages quickly.
Tide’s reader is newer. Most of its feedback comes through the wider banking app, so there is little that speaks to the reader itself.
Support Channels and Response Times
Both lean on in-app support, with limited phone access.
The pattern is the same on each: quick to help with setup, slow when money is held and you need a person that hour.
Reputation Verdict
Square has the longer, more reader-specific record, and we trust it more for that.
Tide’s reader inherits the reputation of the account behind it: well regarded for banking, but carrying the freeze risk above.
Square vs Tide Card Reader for Businesses Already Banking With Tide
If your account is already with Tide, the sums change.
The reader becomes a natural extension of the account. At 0.79% + 3p it is genuinely cheap, once you are past roughly 130 payments a month at a £20 average.
At that level the £17.99 plan pays for itself. Having takings, invoicing, expenses and banking in one place also saves real admin time.
This is the one case where the Tide reader is the obvious choice. Bank elsewhere with no plan to move, and the account requirement alone usually settles it for Square.
Downsides of Square and Tide Card Reader
Downsides of Square
Square’s flat 1.75% grows expensive as your takings rise. It settles only in pounds. And its automated holds can sit on funds for 30 days, with slow support when they do. Outgrow it, and all three start to bite.
Downsides of Tide Card Reader
Tide insists on a Tide account, refuses Amex, defaults to a three-day payout, and charges £2.99 a month for next-day. The till software is basic. The real weakness is the bank dependency: one compliance flag freezes the lot.
Alternatives to Square and Tide Card Reader
If you want the lowest flat rate without tying yourself to a bank, look at SumUp at 1.69% or Lopay from 0.79%. Both take sole traders.
If you take payments in more than one currency, Airwallex settles in the currency you were paid, rather than forcing it back to pounds.
None of these is a full till. Choose on whether you need software, or just a way to accept a card.
Final Verdict: Square or Tide Card Reader?
For most UK businesses, Square is the sounder choice. It is cheaper to start, takes Amex, pays out faster, includes a proper free till, and never asks you to change bank.
It carries the least risk and the least fuss. It is the one we would pick.
Choose the Tide Card Reader only if you already bank with Tide and take enough in person to earn the 0.79% + 3p rate. Inside that ecosystem it is excellent value. Outside it, the account requirement makes Square the wiser bet.
Frequently Asked Questions
Do I need a Tide bank account to use the Tide Card Reader?
Yes. The Tide Card Reader only works with a Tide business account; you cannot route takings to a Barclays, NatWest or any other bank. Square has no such requirement and pays into your existing business account, which is why it suits anyone not already banking with Tide.
Is Square or the Tide Card Reader cheaper?
For low or irregular volume, Square is cheaper because it has no monthly fee. Tide’s 0.79% + 3p plan rate is lower per tap but needs the £17.99 +VAT Sell In-Person plan, so it only beats Square’s flat 1.75% above roughly 130 transactions a month at a £20 ticket.
Does the Tide Card Reader accept American Express?
No. The Tide Card Reader accepts Visa, Mastercard, Apple Pay and Google Pay, but not American Express. Square accepts Amex at its standard 1.75% rate, so choose Square if any of your customers pay on Amex.
How fast do Square and Tide pay out?
Square pays out next business day for free, or within minutes for a 1.5% instant fee. Tide settles in three working days by default, and charges £2.99 +VAT a month for next-day settlement.
Which has better POS software?
Square, clearly. Its free POS app handles inventory, staff, analytics and customers and scales into full retail and restaurant systems. The Tide reader’s software is basic, with no table mapping, kitchen display or barcode inventory.
