In order to decommission a Client (POS device) please follow the following steps:

1. Update client information

If the Client is no longer in use, you must update its status using the Submission API:

• Use the Upsert Client Additional Data endpoint

• Update the following fields:

date_decommissioning: The date the device was decommissioned

decommissioning_reason: A short description or keyword explaining the reason

Common reasons include:

• Sale

• Disposal (e.g. recycling or destruction)

• Theft

• Defect or technical failure

• Relocation to another establishment

Important: Do not delete the Client immediately. First, update the decommissioning fields and report the changes accordingly.

2. Report the changes to the tax authorities

Within 30 days, submit the updated information by creating a new Submission/Transmission via the Submission API.

3. Remove or unlink the client

Once the Submission/Transmission has been completed successfully, you can either:

• Delete the Client from your system, or

• Unlink the Client from the associated establishment if it will be reused elsewhere.

Summary

• Update Client data using date_decommissioning and decommissioning_reason

• Create a Submission/Transmission within 30 days

• Delete or unlink the Client after successful Submission/Transmission
