Edit Existing Suppliers

You can edit a supplier in kolum at any time to update its name, identifier, address, connected companies, or contact persons. Keeping supplier information accurate ensures your emissions data collection, supplier management, and connected workflows remain clear and reliable across your workspace.

How to Edit an Existing Supplier

  1. Navigate to the Suppliers Page. Go to Supply Chain > Suppliers from the sidebar.
  2. Open the Supplier. Find the supplier you wish to edit in the list and click on its name to open the details page.
  3. Click Edit. In the top-right corner of the supplier's page, click Edit to enter edit mode.
  4. Update Supplier Information. You can edit the following sections:
    • Name and Identifier
      • Update the supplier Name (mandatory).
      • Change the supplier Identifier if needed (mandatory). It cannot be left empty, and the new value must not already be used by another supplier in your account. If you do not touch the field, the identifier stays as it is.
    • Address Details
      • Update or correct the address:
        • Street name and number (optional)
        • PO Box (optional)
   - Postal code, city, and country (all mandatory)
   - Use the dropdown for selecting the country (mandatory)
  • Connected Companies
    • Adjust which of your companies are linked to the supplier as purchasing entities.
  • Contact Persons
    • Add new contact persons or edit existing ones as needed.
    • Remove contact persons who no longer need access.
    • Set a different default contact person if needed; this person will receive invitations during invite or bulk invite actions.
    • To invite additional contacts, click the mail icon next to their entry.
    • Ensure contact person emails use the supplier's company domain for security.
    • Wait at least 24 hours before re-sending invitations to the same contact person.
  1. Review Your Changes. Ensure all mandatory fields are filled correctly and the information is consistent.
  2. Save Supplier. Click Save supplier in the top-right corner to apply your updates.

Changing the Identifier

The Identifier is unique per supplier within your account, so kolum validates it when you save.

  • If you enter an identifier that another supplier already uses, the save is refused with a clear "identifier already taken" message and your other edits are not applied. Choose a different value and save again.
  • The check happens on save, not while you type. To see which identifiers are in use, download your supplier list from the Suppliers page.
  • Because the identifier is the key used in the supplier upload and the supplier production facilities upload, update your own files and templates after changing it.

Important to Note

  • Accurate supplier address and company connections help align article assignments and emissions tracking within kolum.
  • If you wish to delete a supplier, you must first remove all linked companies, articles and production facilities before deletion is possible.

After Editing

Once saved, your updates will immediately reflect in your Suppliers list. The edited information will sync across your articles, emissions workflows, and supplier management, ensuring your workspace stays organized and your data remains reliable for ongoing tasks within kolum.

What's new

A changed supplier Identifier is now checked for conflicts when you save: a value already used by another supplier is refused with a clear message, and the Identifier can no longer be cleared. The Supplier Type (Trader or Manufacturer) has been removed from kolum, so it no longer appears on the supplier page or updates on its own.
