Device buyback website case study · 2024: GoldshiroromJapan's used-device buyback, priced online.
Goldshirorom buys used phones, tablets and audio gear from a shop in Shinjuku, Tokyo. The site turns that into a searchable price list: a customer finds their exact model and carrier, sees what it is worth, and picks how to sell it. Built in Japanese, for Japanese customers.

The brief
What we built
Buyback runs the catalogue backwards: the shop is the buyer, prices change constantly, and the model list is enormous. The site had to make that searchable in a few taps.

In the product
What Goldshirorom does
What a seller needs before they will part with a phone: a price, a route and a reason to trust the shop.
Price search
A seller finds their exact model and carrier and sees the buyback price without phoning the shop.
Carrier-aware listings
The same handset is priced per carrier across Docomo, au, SoftBank, UQ, Rakuten and Y!mobile.
Three ways to sell
In-store, mail-in or corporate buyback, each with its own explained flow.
Mail-in paperwork
Application and parental consent forms download straight from the site.
LINE enquiries
A LINE official account handles questions and reservations on the channel Japanese customers actually use.
Highlighted models
Reinforced buyback items are surfaced first, so the stock the shop most wants is what sellers see.
Want one of your own?
A large, constantly-changing catalogue that has to stay searchable is the same problem whether you are selling or buying. We build both.
