The Add facility form opens with a single question — “Who operates this facility?” — answered My company or A supplier or subcontractor. On the manufacturing step it starts on My company for companies with the Manufacturer role; on the components step My company appears only for companies holding another role.
For a supplier already in your list there is a search dropdown, which now returns results for any name, plus an Add new supplier option.
For a new supplier the tax ID comes first and is checked as it is typed — Checking, Found or No match — and nothing else appears until the check finishes or “I don't have this supplier's tax ID” is ticked. Entering the company's own tax ID is recognised and says so.
On a match, the supplier's legal name is shown marked On platform, with its current roles and its contact emails masked to the first and last letter. Roles and emails are locked: new ones can be added, nothing can be removed. The supplier then picks one of that company's existing sites, with the headquarters tagged, or adds a new facility — the manufacturing step lists production sites only, the components step lists all locations. Saving links the facility without creating a duplicate supplier.
With no match or no tax ID, legal name, contact emails, roles, headquarters and facility location are asked in the same panel. Errors appear together on submit with a count of the fields needing attention, and a confirmation screen shows who operates the facility and where. All new text is available in the ten supported languages.
