SimplyBook.me vs Square Appointments for a Solo Practitioner
Disclosure: Some links on this page are affiliate links. If you sign up through one, we may earn a commission at no extra cost to you. It does not change what we recommend — both tools below are measured against the same criteria, and one of them pays us nothing.
These two end up on the same shortlist constantly, and they are not really the same kind of product. One sells you a booking business. The other gives away the booking and takes a cut of the money.
If you are a massage therapist, a nail technician, a personal trainer, a tutor or a solo consultant deciding between these two, the choice is not about features. Both take bookings, both send reminders, both accept cards. The decision comes down to three things: what your money actually costs to collect, whether you can send clients somewhere that looks like your business, and how hard it is to leave.
This page settles those three, with the arithmetic done at real volumes.
The short answer
Take SimplyBook.me if you want a booking page that looks like your own business, if you take deposits before the appointment, or if you sell packages and memberships. You pay a subscription for that, and the subscription is small.
The rest of this page is why, and what it costs at your volume rather than in general.
They charge in completely different places
This is the whole comparison, and most reviews skip it.
| SimplyBook.me | Square Appointments | |
|---|---|---|
| Monthly fee | Free tier; Basic from 11.90/mo on annual billing | $0 on the Free plan for one person |
| Fee per payment | None charged by SimplyBook.me — your own processor's rate applies | 2.6% + 15¢ in person, 3.3% + 30¢ online |
| What caps you | Bookings per month and number of features switched on | Nothing. Volume is unlimited |
| Booking page | Your own branded site, your own domain | A Square-hosted page |
| Payments | Connect your own processor | Square only |
On these figures. SimplyBook.me serves its pricing in the currency of the country you browse from — the tier structure is identical everywhere, but check which currency you are being quoted. Square's processing rates below are its published United States rates. Both were read from the vendors' own pages on 14 August 2026. Where a figure could not be verified, this article says so rather than guessing.
The arithmetic, at three real volumes
A subscription of 11.90 sounds bigger than $0. Run it properly and the ranking flips depending on how you get paid.
Monthly total = subscription + ( appointments × [ average ticket × rate + fixed fee ] )
Square's in-person rate is 2.6% + 15¢. SimplyBook.me charges nothing per payment, but your processor will — put your own processor's rate in where noted.
Case 1 — 20 appointments a month at $60, paid in person
Square: 20 × ($60 × 0.026 + $0.15) = $34.20. No subscription. Total $34.20.
SimplyBook.me: 20 bookings fits inside the free tier's 50-booking allowance, so the software is free — but the free tier gives you one custom feature, and "accept payments" is one of them. Assume Basic at 11.90 to have payments plus one more feature. Then add whatever your own processor charges on those same 20 payments.
At this volume, Square is cheaper unless your processor beats 2.6% + 15¢, which few do for card-present transactions.
Case 2 — 60 appointments a month at $60, paid in person
Square: 60 × ($60 × 0.026 + $0.15) = $102.60 a month. Still no subscription. Total $102.60.
SimplyBook.me: 60 bookings exceeds the free tier's 50. Basic covers 100 bookings at 11.90. Add your processor's fees on 60 payments.
Square is still likely cheaper on card-present work — but notice what has happened: Square's bill tripled while SimplyBook.me's went up by one tier. The gap is closing, and it closes faster the higher your ticket goes.
Case 3 — 30 appointments a month at $200, paid by bank transfer
This is where it inverts. Square's ACH rate for invoices is 1% with a $1 minimum, and the paid tiers cap it — but on cards at this ticket, 30 × ($200 × 0.033 + $0.30) = $207 a month online. Two hundred dollars a month, for software that advertises itself as free.
SimplyBook.me at 24.90 (Standard, 500 bookings) plus your processor's fees will almost always come in lower at a $200 ticket, because you are not paying a percentage to the booking software on top of the percentage you already pay to your processor.
The rule that falls out of this: the higher your average ticket, the worse a percentage-based booking tool gets. Below roughly $80 a visit, Square's in-person rate is hard to beat. Above it, a flat subscription starts winning, and keeps winning.
Who owns the client
The second question is not about money this month. It is about whose business the client thinks they are booking.
SimplyBook.me
You get a booking site under your own name, on your own domain if you want one, with your services, your policies, your look. To a client it reads as your business, because it is. Memberships, packages, class schedules and intake forms are all available at low tiers.
The cost of that is configuration. There are two meters running — bookings per month and how many "custom features" you have switched on — and the feature count is what pushes most solo practitioners up a tier, not the booking count. Price it with the features you need turned on, not from the headline number.
Strong
- Looks like your own business
- Memberships and packages at a low tier
- You choose the payment processor
Weak
- Two limits to track at once
- Dense interface on first contact
- Setup takes an afternoon
Checked against simplybook.me/en/pricing. Currency is served by country.
Square Appointments
Setup is measured in minutes and there is nothing to configure about billing, because billing is the product. Booking, payment, receipts and reporting are one system, and reconciliation stops being a weekly chore. For a practitioner who already takes cards in person, that single-ledger effect is worth real time every month.
What you give up is control of the payment side. You cannot shop for a cheaper processor, because Square is the processor. Your booking page is hosted by Square and looks it. And your entire payment history lives inside a system you cannot export as a working ledger if you leave.
Strong
- No monthly fee for one person
- Lowest card-present rate here
- One system for booking and money
Weak
- Online card rate is high (3.3% + 30¢)
- Locked to one processor
- Page is Square-branded, not yours

How hard is it to leave
Nobody asks this before signing up, and everybody asks it two years later.
Leaving SimplyBook.me costs you a booking page and a configuration afternoon. Your client list exports. Your payment history lives with your own processor, which you keep. If you had your own domain pointed at the booking page, the domain is still yours and can point somewhere else tomorrow.
Leaving Square costs more than it looks. Client records export, but your payment history — the actual record of what each client paid you and when — is inside Square's system. You can download reports; you cannot move a working ledger into another tool. And any card on file has to be re-collected from every client, one at a time. That is not a reason to avoid Square. It is a reason to choose it deliberately rather than by default.
Which one, concretely
Massage therapist, $70–90 a session, clients tap a card at the end. Square. Your ticket sits in the range where 2.6% + 15¢ is cheap, and one ledger for bookings and takings will save you an hour a month.
Tutor or consultant, $150+ an hour, invoiced or paid by transfer. SimplyBook.me. At that ticket a percentage on every payment is the most expensive line in your business, and you want your own processor and your own bank route.
You take deposits to stop no-shows. Both can. SimplyBook.me gives you more control over the policy and the wording; Square makes it faster to switch on. If no-shows are actively costing you money right now, either is better than what you have.
You sell packages, courses or memberships. SimplyBook.me, clearly. It is built for that and it is available at a low tier.
You already use Square for retail or in-person sales. Square Appointments, without much thought. Adding a second system to a working till is a cost you would be paying for no benefit.
What neither pricing page tells you
Three costs sit outside both pricing tables, and between them they are usually bigger than the difference you have been agonising over.
The hardware, if you take cards in the room
Square's software is free, but the thing you tap a card against is not. A basic contactless reader is a one-off purchase, and if you want a countertop terminal or a stand for a tablet, that is a larger one. This is a real cost and it is paid once, so it barely matters over three years — but it is the difference between "free" and "free after $59," and nobody mentions it until checkout.
SimplyBook.me does not sell you hardware, because it is not your processor. Whatever reader your own processor supplies is the one you use.
The time you spend on setup, once
Square is genuinely a coffee-break setup. Services, durations, prices, done. SimplyBook.me is an afternoon: you are choosing which custom features to switch on, configuring a booking page, deciding policies, and possibly pointing a domain at it.
Price that honestly against your own hourly rate. An afternoon of a $150-an-hour consultant's time is several years of the subscription difference — which argues for Square. An afternoon of setup that produces a page clients trust enough to book without phoning first argues the other way. Both are true; only you know which applies.
The fee you already pay, and forgot about
If you go with SimplyBook.me, you still need a payment processor, and that processor charges you. The comparison above is not "11.90 versus $0" — it is "11.90 plus your processor" versus "$0 plus Square's rate." People run the first half of that sentence and stop.
So before choosing: open your current processor's fee page and write down the card-present rate and the online rate. Those two numbers, not the subscription, decide this.
If you are already on one and thinking of moving
Most people reading a head-to-head comparison are not starting from zero. They are on one of these already and wondering whether the other is better. The honest answer depends on which direction you are going, because the two moves are not symmetrical.
Square to SimplyBook.me
Straightforward, with one real cost. Export your client list, rebuild your services in SimplyBook.me, connect your own processor, then run both for one booking cycle so nothing in the diary falls through the gap. Your historic Square payment records stay in Square — download a full report before you stop paying attention to that account, because your accountant will ask for it eventually.
The thing that actually hurts: any card you had on file at Square does not move. Every client on a recurring or package arrangement has to enter their card again somewhere new. Expect to lose a few to that friction, and time the switch for your quietest month.
SimplyBook.me to Square
Easier, and worth doing if your volume has shifted toward small in-person tickets. You keep your own processor history because it was always yours. You lose the branded booking page and any memberships or packages you had configured — those do not have a like-for-like home in Square Appointments, and rebuilding them is the part people underestimate.
Either way: do not switch mid-tax-year if you can avoid it, and download everything before you close an account rather than after.
Questions people actually ask
Can I use both?
Yes, and some practitioners do — SimplyBook.me for the booking page and policies, Square as the card reader in the room. It works, but you are now reconciling two systems, which is the exact chore Square exists to remove. Do it only if the branded booking page is worth that to you.
Does the free plan of either one actually work?
Square's free plan is a real product for one person, with no volume cap. SimplyBook.me's free tier caps you at 50 bookings a month and one custom feature, which is enough to test the thing but not enough to run on if you are busy. Different kinds of "free": one is funded by your payment fees, the other by your eventual upgrade.
Which one looks more professional to a client?
SimplyBook.me, if you configure it. A booking page on your own domain with your own branding reads differently to a client than a Square-hosted page — particularly for services where trust is being purchased alongside the appointment. Whether that difference is worth the subscription depends entirely on your market.
What if I grow and hire someone?
Both handle it, at a cost. Square Appointments moves you off the free plan once there is more than one person. SimplyBook.me's tiers are driven by bookings and features rather than headcount, so growth pushes you up more gradually. If you expect to hire within a year, model that tier now rather than later.
The thing that actually decides it
Work out your average ticket and how your clients prefer to pay. Those two numbers settle this, and no feature comparison can override them.
Under about $80 a visit, paid in the room by card: Square is very hard to beat, and the single-ledger effect is a genuine time saving. Above that, or where clients pay by transfer or invoice, a percentage on every payment becomes the largest software cost in your business, and a flat subscription with your own processor is the cheaper structure.
One last thing, which applies to both. Neither of these tools will fix no-shows unless you write a cancellation policy and let the software enforce it. That decision costs nothing and is worth more than the difference between these two products.
Write the policy first, then pick the tool that can carry it. Done in that order, either of these will do the job, and the money you save is the money you were previously losing to empty chairs rather than to software.
