The one-page specification sheet that prevents most production disputes: every field a factory needs to quote and produce correctly, with the wording conventions that leave no room for interpretation. Fill one per style and attach it to every purchase order.
What the template covers: metal and plating specification with micron thickness, stone callouts by name and millimetre size, dimensioned drawings checklist, weight tolerance, closure and hinge requirements, packaging per unit and per carton, and the compliance documents required with the shipment.
Use it with the quotation guide: a supplier who returns the sheet completed and questioned is a supplier worth working with; one who ignores it has told you how production will go.
