A custom profile means a new lathe form, a first-article inspection against a master gauge, and a sampling round before anything is committed. That development cost is real and we quote it separately rather than burying it in the unit price, because burying it makes a first order look cheap and every reorder look expensive.
For most programmes under a few hundred pieces, a custom profile is not the right spend. Ten existing profiles, five diameters and four bead counts already give two hundred combinations, and a well-chosen combination from that set usually reads as distinctive to a customer while costing nothing in tooling. We will say when we think that is the better answer, even though it is the smaller invoice.
Where a custom profile does earn its place is a programme with a multi-season life and a brand that needs to own a silhouette. Then the tooling amortises, the profile becomes yours by reservation, and the production file makes the third season match the first. That is a different conversation from a one-off, and it should be priced as one.
