If you make furniture, the enquiry could collect available width, photos and the desired number of seats. Customers would compare the materials and finishes you offer. You would then prepare a sketch for approval. The project record would retain confirmed dimensions, the final selection and delivery instructions; an initial request for information would never automatically trigger production of a custom item.
An illustrative example to adapt to your business. It does not represent a completed project in this municipality.
How should standard and custom models differ online?
Standard product pages show fixed dimensions. The custom enquiry collects project constraints and explains that a quote will follow your review of the information supplied by the customer.
Do prices need to appear immediately?
An indicative price can help when its inclusions are clear. The final quote would depend on dimensions, the selected material, finish and the delivery arrangements agreed for the project.
