Guide to the Square integration

This guide is designed to pull together all of the information you need to get up and running with Square to streamline your invoicing and reconciliation processes.

Square is only available to WriteUpp users based in the UK. For those of you who are not UK based, you will be able to set up Stripe.

Did you know that Stripe Unified can offer you lower transaction fees than a standard Stripe account, so why not consider integrating with Stripe instead? If you do wish to continue with the Square set up, please contact support and we will enable the integration on your site.

The Square integration allows you to:

Accept prepayments via online booking
Take card payments in clinic
Offer online invoice payments post treatment

You can read an introduction to, and a little bit more about, Square here -> Introducing Square

Setting up the Square integration

As with most integrations, there are a few setup steps you'll need to follow before you can make use of all of the fantastic features that the Square integration offers. These steps are generally one time processes to get you underway.

Getting started

First, you'll need to connect WriteUpp and Square -> Connecting WriteUpp to Square

Setting up in person payments

Next, you can set up in person card payments.

You'll do this by pairing a Square terminal to WriteUpp -> Pairing a Square Terminal for in person payments

If you don't have a Square terminal yet, worry not. You can come back and do this at a later date! You can set up online payments initially and pair a terminal for in person payments when you are ready to provide an end to end pathway covering both in person and online payments!

If your business expands and you need to add another terminal at a different location, that's also not a problem. Just follow the steps again to pair multiple terminals to a single WriteUpp account so you can take payments wherever you are!

Setting up online payments

You'll also be able to set up online payments to accept both prepayment of appointments made via online booking, and to allow your clients to pay an invoice securely online.

To set up for online payments via Square, you'll need to choose a location from your Square account that these payments are allocated to -> Setting up Square online payments

To allow clients to pay their invoice online, you'll then need to add a pay link to your invoice footer -> Adding a Square payment link to invoices

And if you'd like to take online booking prepayments (which can be a great way to reduce your DNA rate!), you'll need enable online booking prepayments within online booking -> Switching on Square prepayments for online booking

Taking payments via Square

Once you've completed the set up steps above for the payment pathways you'd like to use, you're ready to start taking payments from your clients! Read on to find out more about each of those pathways...

Taking in person payments

In person card payments can be taken from several different places within WriteUpp. The process you'll follow to take a card payment via the Square terminal is generally the same in each of those places.

A quick card payment can be taken directly from the appointment details for a non-invoiced appointment -> Quick card payments using the Square terminal

ALL user roles will have access to take a quick payment of an appointment via this pathway. This includes Regular and Restricted users who have have no wider access to financial information

Invoice payments can be taken from the bottom of a saved invoice -> Invoice payments using the Square terminal

Site administrators and Privileged users will be able to take a card payment for a saved invoice

An invoice part payment can also be taken using the terminal -> Invoice part payments using the Square terminal

Site administrators and Privileged users will be able to take a part payment via card for a saved invoice

Online invoice payments

Covering situations where you might be conducting remote appointments, online invoice payments provide a secure way for your clients to pay in their own time either before or after a session.

Online booking prepayments

Requesting online booking prepayment from your clients can be a great way to reduce your DNA rate, and to limit the time you spend dealing with payments post treatment.

Online booking prepayments are covered in more details here -> Online booking pre-payments with Square

Switching from Stripe to Square

If you're currently using Stripe, you can quickly switch over to using Square instead,

You can find the switching process covered here -> Switching from Stripe to Square

Disconnecting Square

If you'd no longer like to benefit from the seamless omni-channel payments provided by Square, you can disconnect from Square at any point.

Disconnecting from Square is covered here -> Disconnecting your Square account
