The $30k+ developer nightmare nobody puts in the proposal
Agencies quote a storefront. They do not quote the fitment engine, the supplier integrations, the package builder, or the person who fixes feeds at 2 a.m. when a warehouse changes a CSV column. In wheel and tire retail, those are not optional extras — they are the product.
A general web developer understands carts and payment gateways. They do not understand staggered BMW offsets, load-index rules on plus-sized truck tires, or why three distributors name the same SKU three different ways. Months of back-and-forth still produces a site that sells unsafe combinations if fitment is not enforced at checkout.
