Case study

A specialist catalogue that a small team can actually merchandise.

Golf equipment is a fitting problem disguised as a retail problem. Shafts, flex, hand, loft and lie mean a single product line explodes into variants, and a store that models that badly becomes unmanageable long before it becomes unprofitable.

01 / The problem

What was actually hard.

The catalogue is the hard part. Irons, gloves, headwear, shoes and accessories each carry different variant axes, and the naive approach — a product per permutation — produces thousands of near-duplicate records that nobody can merchandise, search, or keep in stock correctly.

Selling internationally compounds it. Pricing, shipping thresholds and delivery expectations differ by destination, and a threshold like free shipping over a given order value has to be enforced consistently at the cart, not implied in the copy.

02 / What we built

The system.

A variant model that holds
Products modelled with their real attribute axes rather than flattened into permutations, so stock, pricing and imagery stay attached to the right thing.
Category and discovery structure
Browsable categories with counts, filtering and search built over the attribute model, so a customer can narrow by the axes that actually matter to them.
Cart-enforced shipping rules
Order-value thresholds and destination rules applied in the cart, so what the banner promises and what the customer pays are the same number.
Accounts, wishlist and returning customers
Registration, wishlist and order history — the machinery that turns a one-off purchase into a second one.
Merchandising a small team can run
An admin surface built for a handful of people, where adding a line or running a promotion does not require an agency ticket.

03 / What carried over

Decisions worth reusing.

The parts of this build that we would apply again on a different problem in a different sector.

Model the domain, not the screens
Getting the variant model right early is what keeps a specialist catalogue manageable at a thousand SKUs. Retrofitting it is close to a rebuild.
Rules belong in one place
Shipping and pricing logic enforced server-side at the cart rather than repeated in templates, which is where the discrepancies customers notice come from.

Next step

Have something like this to build?

Start with a diagnostic. It is fixed-fee, time-boxed, and it will tell you honestly whether the thing is worth building — including when the answer is no.
