After each payment you will receive an email which informes you that a new pay slip is available. You can view your pay slips in your Kolibrie Online account and/or in the Kolibrie app. In Kolibrie Online you will find your pay slips on the left under 'documents'. You can find your pay slips in the app by clicking on 'Payments'. If your pay slip states TWK, this means that this is a pay slip with retroactive effect.
Here you can find a detailed explanation of each part of the pay slip.
