A parts distributor could offer a reference search and an inquiry path for items that cannot be found. The form would gather quantity, known dimensions and a photograph of the part being replaced. We could route it to the category specialist and prepare a reply with availability and a proposed option. Any equivalent part would be confirmed by the company before accepting an order.
An illustrative example to adapt to your business. It does not represent a completed project in this municipality.
What if a customer does not know the part number?
An entry point based on use and a photograph can start the conversation. The website would identify useful measurements or markings, then leave final identification to your team.
Does the website need to show live stock?
That depends on inventory reliability and its connection to the website. A clearly described availability inquiry can work better when staff still need to verify the item before confirmation.
