If you use the „Inventory feature“, your voided articles will automatically be restocked.

  • Note: This process is only applicable to transactions that have taken place on the same business day as the return! Returns can only be conducted by employees with the respective rights. Note that card payments are not automatically refunded to your bank account!

2- Other Questions

This section discusses other, more general questions on the SumUp POS App.


2.1- How do I receive software updates for my Point of Sale system?

We recommend using both the latest iOS version as well as the latest SumUp POS App.

This is how you update your iPad to the latest version:

  1. Please do not conduct an iOS update during an opened business day.
  2. Open the iPad setting and choose "General" and next "Software Updates".
  3. Follow the instructions given on your iPad's screen. After finishing the update you also have to "trust" the SumUp POS app developer.
  4. Open the iPad settings, choose "General", scroll downwards on the right side and click on "Profiles & Device Management". Choose "Mujinzo Labs GmbH Ent" and click on "Trust Developer". Confirm this step and close the settings. You can now open the POS App.

This is how you update the POS App to the latest version:

You will receive an in-app notification if there is a new version of the SumUp POS App. You can simply click on "Update" button in the notification.

If you have not yet installed the app on your iPad or have just updated your iPad's iOS please follow these steps:


2.2- When I open the SumUp POS App, there is always a specific employee logged in by default. Can I change that?

Upon opening the SumUp POS App there is always one employee logged in by default. If you want to change that please contact our customer support.

To simply log in a new employee during the working days click on the employee's name in the top bar of the app and click on "Logout". The other employee can now type in his employee PIN.


2.3- Can I disable receipt printing?

In the lower right corner of the app you can see a button saying "Print enabled". By clicking on it you change it to "Print disabled" and "Print receipt".

If you have set the button to "Print disabled" no receipt will be printed.


2.4- What can I do if I opened/closed the business day by mistake?

In this case we ask you to contact our customer support.


2.5- What happens if the internet connectivity is discontinued?

The POS App can be used without an active internet connection. If the internet connectivity is discontinued you can not accept card payments since transactions can not be verified properly.

If you experience a disturbance of the internet we recommend you to fix it as soon as possible to be able to accept card payments and to enable synchronisation with the POS Cloud.
