A visit nobody charged
The booking never met a payment.
BoldBellowsSimplyBook.me to Square automation for businesses that book online and take payment at the counter or the card reader
SimplyBook.me to Square automation that ties each booking to its Square customer and payment, lists unpaid visits and records every adjustment with a reason
SimplyBook.me to Square integration matters when clients book online and pay later, at a counter or on a reader. Square requires an idempotency key on a payment write and counts money in the smallest unit of the currency, so a retried request must repeat the key and the cents must agree with the booking. BoldBellows notes the booking ID and the amount SimplyBook.me expects for the visit, fetches the whole booking through the API and looks in Square for a customer and a payment carrying that booking's reference, then ties the booking to the customer and the payment by reference ID and records one verdict per visit: paid, partly paid, unpaid or adjusted. Connect SimplyBook.me to Square this way and the counter and the calendar tell the same story.

01the paid-at-the-counter problem
A visit paid at the counter is easy to lose between two systems
The calendar says the client came; Square says somebody paid sixty dollars; nothing says they are the same visit. A discount at the till changes the amount, a tip adds to it, and a client who paid for two people on one card matches nothing in the booking. The owner closes the day with a stack of unpaid appointments and no way to tell which are genuinely unpaid.
An amount that differed
A discount or tip changed the total.
Two clients, one card
One payment covered two bookings.
SimplyBook.me visits and Square payments, finally matched
Before: events become ledger lines unchecked
- Notifications are forwarded without a check
- Counter payments and bookings are matched by eye
- Unpaid visits are found at month-end
After: events are admitted by rule
- Records are matched on the booking ID stored as the Square reference ID, not on names
- Every visit has a verdict and a payment reference
- Unpaid visits are listed the same day
02how it works
How a SimplyBook.me booking becomes a visit matched to its payment
Qualify first, match second, write last; that order is what stops duplicates.
- Verify and decide. The incoming Square event is checked for authenticity, its identifiers are recorded, and the route decides whether the booking change qualifies.
- Read, find, compare. The booking is read from the API, Square is searched by reference ID and customer, and the booking amount is compared with what was paid.
- Record, adjust, explain. The verdict is stored, any discount or tip is recorded with its reason, and every Square write carries an idempotency key.
What the platforms dictate
- Locations split the business. A company can run several locations, with services and providers assigned to each, so the build carries the location along and never assumes one calendar per company.
- An idempotency key on every write. Square asks for an idempotency key on creating a payment or an order and treats a repeat of the key as the same request, and its Money values are whole numbers in the currency's smallest unit.
- Recovery. Anything unclear is reconciled against Square through the booking ID stored as the Square reference ID, then repaired, closed or handed to an owner.
03The deliverables
Inside the payment ledger, the parts that match, adjust and list
Three layers, in order: Capture for eligibility and identity, Coordinate for the ledger line itself, Audit for drift and exceptions.
CaptureCoordinateAudit
Scope filter Capture
Applies the in-scope list to every SimplyBook.me event, so Square sees only what you approved.
Stable identity ledger Capture
Maintains the link between a SimplyBook.me record and its Square twin, so updates land in the right place.
Field-level filter Capture
Drops, masks or transforms each SimplyBook.me value according to the rule written beside it.
Customer and payment linker Coordinate
Finds or creates the Square customer and ties the payment to the booking by reference ID.
Reference and key matcher Coordinate
Matches each event to its ledger line by the booking ID stored as the Square reference ID and flags the ones it cannot place.
Adjustment rules matrix Coordinate
Records discounts, tips and part payments with the reason and the person who approved them.
Payment register Audit
Holds every difference between SimplyBook.me and Square with its age and its owner.
Unpaid-visit monitor Audit
Lists visits past their date with no matching payment.
Repair workbench Audit
Offers a safe next action for each stuck ledger line instead of a blind retry.

04Who it's for
When clinics and therapy practices scheduling visits through SimplyBook.me also have to see every booking beside the Square payment that settled it, and spot the ones with no payment at all
SimplyBook.me holds who was booked; Square holds what was paid, and the owner needs both on one line.
Owner
"Which visits went unpaid?"
A same-day list shows every visit with no payment.
Bookkeeper
"Match the till to the calendar."
Each booking carries the Square payment behind it.
Front-desk lead
"Answer 'did I pay?'"
The booking shows its payment state at a glance.
Provider
"See my tips and sales."
Adjustments are recorded against the visit and the provider.
Multi-location manager
"Several Square locations."
Each booking is matched within its own location.
Founder
"Close the day in minutes."
Verdicts replace a manual comparison.
05Compare
SimplyBook.me into Square: a booking-and-payment ledger route, or the usual a payment link added to a confirmation email and zap
Each can record a payment. Only one ties it to the booking and explains every difference.
| What sets it off | A payment link added to emails | A basic SimplyBook.me Square zap | Our booking-and-payment ledger |
|---|---|---|---|
| What starts the work | Staff notice and act | The first matching notification | YesEvents inside the agreed scope only |
| How identity is decided | A person recalls the customer | Nothing stored, so nothing to compare | YesThe booking ID as reference on the Square payment, plus an idempotency key |
| What reaches Square | A partial copy | One object, no relationships | YesA verdict per visit, with adjustments and unpaid lines recorded |
| After an uncertain result | A manual clean-up later | It repeats the write | YesCompares what exists with what was intended |
The newer state is already there
When an older event shows up after a newer one, the route notes it and leaves the confirmed ledger line alone.
One card pays for two clients' bookings
The payment is matched to both bookings by reference, the split is recorded, and the verdict for each visit shows its share. The existing ledger line, if any, is found by the booking ID stored as the Square reference ID and judged against the payload before the route decides what to do. Only a confirmed absence permits another ledger line.
The first design choice is the booking ID stored as the Square reference ID; identity, replay and repair all follow from it.

Build your SimplyBook.me to Square price
Pick a package, answer three short questions about how SimplyBook.me data should reach Square, and your price and turnaround move as you choose.
06The process
Six steps from counter payments to a ledger that agrees
The route is built in six steps, and nothing moves on until the last one is signed.
Choose the rules
We agree what counts as paid, which differences are normal such as tips, and when an unpaid visit should be listed.
Approve access
The connections between SimplyBook.me and Square are made with limited, revocable permissions.
Agree references and adjustments
The reference format, adjustment reasons and who approves each kind are written down and signed off.
Prove the repairs
Each failure path, from a lost reply to a rejected value, is exercised in a test Square before the live switch.
Launch with notes
Once tests pass, the route goes live from a set checkpoint and the documentation is delivered.
Early-life support
Questions about how the route behaves in production are answered during the launch window, and the notes are updated.
07Turnaround
How many days each package needs
Days are counted from approved access, not from Square payment.
Capture
6 to 10 business days
Coordinate
10 to 16 business days
Audit
16 to 24 business days
08Before we start
What you need to hand us
Read access to the SimplyBook.me data the route will use
Square developer access for the locations in scope, and API access turned on in SimplyBook.me
Permission to subscribe to the SimplyBook.me events that start the route
Agreement on which booking changes are in scope for the first release
A contact who can approve changes to the field map
Names of the people who will receive the handover notes
09Security and ownership
Least access, allowlisted fields, and a clean handover
Think of it as a pipe with two labelled ends: SimplyBook.me on one side, Square on the other, and nothing kept along the way.
No changes to either product
SimplyBook.me and Square keep their own code and settings; the route sits between them and uses only what each platform documents.
Scoped, revocable access
Each connection has the narrowest permissions that work, recorded in the handover.
A short list of fields
The mapping names every field that travels. Additions are agreed in writing, not picked up automatically.
No blind replays
The route never resends on hope. It checks Square for the ledger line through the booking ID stored as the Square reference ID and decides from what it finds.
Minimal logging
Diagnostic records are deliberately thin, so there is little to protect.
Full handover
There is no lock-in; the notes explain every setting we chose.

11FAQ
SimplyBook.me, Square and counter payments: questions from owners
Read these first; whatever is left can be asked in your quote request.
Can a SimplyBook.me to Square Zapier integration retry safely?
Need only a Square customer for every client? A zap handles that. It stops short of the work to tie each booking to the Square customer and payment behind it, list the visits that were never paid for and record every adjustment with its reason. That missing layer is what you are paying for.
What links a Square payment to a SimplyBook.me visit?
The route reads each booking, finds the Square customer and payment by reference ID, and records a verdict per visit.
Does it take payments?
No. It reads payments and records verdicts. Any write to Square, such as a customer record, carries an idempotency key.
What if the amount differs from the booking?
The visit is listed as adjusted, with both amounts and a reason, such as a tip or a discount.
What about a client who paid for two?
One payment can be matched to two bookings, and the split is recorded.
Can visits paid before launch be reconciled?
Yes. Earlier visits are compared with Square payments in resumable batches, and anything unmatched becomes a line for review.
Can Square change a booking?
No. Square is read and annotated only, so nothing done at the counter edits a booking.
Is there a written map at handover on the SimplyBook.me to Square route?
Yes, and it is part of every package: our SimplyBook.me Square field mapping service assigns each SimplyBook.me field a destination, a type and a format for your sign-off before the build starts.
Can we combine several triggers?
Yes. The route is built around your logic, so it is a custom SimplyBook.me workflow for Square with a SimplyBook.me Square integration consultant's care behind it, from $970.
Will an update to Square break the route in the SimplyBook.me to Square route?
If the platforms change, the route degrades gracefully: it holds the affected record and flags it. Follow-up support once your review window ends is quoted on its own.
