To encourage customer loyalty, you can register customers in Abacus.

If you have the Abacus Customer Loyalty module, you will also be able to reward them through your own points system.

Register a new customer

To register a member to your customer loyalty system:


2. A form will appear. Fill in at least their:

  • First name
  • Email address
  • Phone number

3. (OPTIONAL) Tick Print a temporary member card if you wish to instantly print the QR code that is linked to their account. This allows them to scan it in later.
4. Press Register

5. The customer's name will appear at the bottom of the order.

You can also register a customer on the backend in the Customers page

  1. Click New Customer

2. Enter the following details:

  • First Name 
  • Email address
  • Mobile phone number

plus any other information you want to keep track of.

3. Click Save 

Search for an existing customer

Press the Customer field at the bottom of the order to search for an existing member to add to the order.

Use QR Codes for customers

Scan in customers

If you have previously printed out the QR code for the customer when registering them on the POS, you can press the barcode icon at the top of the screen, and scan it in.

Print Customer QR Codes as temporary cards from the POS

For new customers, tick Print a temporary member card.

For existing customers, press PRINT CARD.

A temporary card for your customer will be printed out from the POS printer.

Create QR Codes ready for new customers

If you want to prepare QR codes (e.g. as plastic cards) before actually registering customers, you can create "unregistered" customers, i.e. empty customer listings with pre-defined QR codes, so you can scan a new customer in and give them the pre-made QR code.

  1. On the backend, go to the Customers page and click Generate Unregistered Customer
  2. Select how many "unregistered customers" you would like to create. This is the number of blank QR code templates ready for you to scan in and sign up any customer

3. A csv file will be downloaded with:

  • Member codes
  • Usernames
  • Temporary passwords

For these to be used in future transactions, they need to be attached to QR codes.

Create the QR code

Both registered and unregistered can have their member code linked to a QR code.

  1. Go to your preferred online QR code generator, e.g.

2. Ensure that the ‘Text’ option is selected.

3. Enter a customer’s member code, preceded by a semi-colon (;) and no spaces in Free Text (e.g. ;2018814). 

Member codes for already registered customers can be found on the Customers page (via Loyalty Marketing). 

Member codes for unregistered customers can be found in the CSV file downloaded earlier when clicking Generate Unregistered Customer. 

4. Download the QR code thus generated.

5. The QR code can then be printed on a membership card or emailed to a customer. 

Note: Only one customer can be paired with each individual QR code.

6. On your POS register, tap the Barcode icon to launch the iPad’s camera. This will allow you to scan the code and attach it to a customer profile. This can also be done by connecting a scanner to the iPad.

Note: Provided your POS has internet connection, customers can be scanned straight away without a sync.

Scan on a Customer-Facing Display

If you have a customer-facing display set up with your POS, there needs to be at least one item added to your customer's order before they can be scanned and attached to the order.

  1. Tap the Scan Membership button
  2. A popup will ask you to give the app permission to use the camera
  3. Press OK. You only need to give the app permission once to scan the camera.

4. The scanner will load
5. Ask your customer to show the QR code for their membership. There are two possibilities:

  • They are already a registered customer
  • They are not yet registered, but you have given them a pre-made membership QR code so you can register them on the spot 

Note: You need to start taking an order before scanning in the customer, otherwise they will not be attached to any order. If you have scanned them in too early, you can still look them up on the POS customer database to load them to the order.

Change customer details

  1. On the backend, go to the Customers page 
  2. Click the pencil button next to a customer 
  3. Edit their details, then click Save
