Fulfilment company website
Rollgang: a fulfilment website in Podolsk with a calculator and seller guides
A demo website for Rollgang, a made-up fulfilment warehouse in Podolsk: services for Wildberries, Ozon and Yandex Market sellers, a calculator, a run schedule and 14 seller guides.
The task
Every new seller asks what one unit will cost and when the next run to Koledino leaves, and the manager works it out in a spreadsheet. The site should show the price and the schedule without a call, and new sellers should find us through answers to their own questions.
What we built
- 14 seller guides on queries from Yandex and Google suggestions
- A monthly calculator by price list line, cost per unit and volume discount
- A weekly and monthly run schedule, 4 marketplace warehouse pages
- 38 pages, JavaScript on two, Lighthouse on mobile 97-100
A made-up company, checked facts
Rollgang does not exist. The 4,200 m² warehouse, the address, the rates, the run schedule and the home page figures were invented for the demo, and there are no reviews. The request form checks the fields and replies with a “demo” label, nothing goes to a server. The marketplace warehouses are real: Koledino, Elektrostal, Khorugvino and Sofyino. Distances are approximate.
14 guides for questions sellers type into search
The guides are the core of the demo. We collected Yandex and Google suggestions for phrases like “fulfilment for marketplaces” and picked 14 topics sellers search for. Among them: how to start selling on Wildberries from scratch, FBO or FBS on Ozon for a beginner, and sole trader or self-employed. Another guide answers which goods need Chestny Znak labelling in 2026.
Marketplace rules, fees, labelling and taxes were checked against primary sources as of October 2026. Each guide lists its sources and shows an “up to date as of” date, and fees are marked as approximate. A seller finds such a guide long before they need a warehouse.
A calculator that prices the month line by line
The seller enters units per month and per box, then picks packaging, labelling, storage, the number of FBO supplies and the warehouse. The table on the right puts every operation on its own line, then the volume discount, the monthly total and the cost per unit. The home page example runs on the same code at build time, so the figures match. More on the fulfilment company website page.
Night shift at a sorting centre
The site is a sorting floor at night: violet board lights and an acid-lime scanner signal on the main button and the total. Boxes ride a roller conveyor of service stations. Navigation is a control panel with isometric icons at the bottom of the screen.
- 38 pages and a 404 in static HTML. JavaScript runs only in the calculator (about 8 KB) and the request form, and the SvelteKit runtime never loads. The popover menu and the schedule filter work without it.
- Lighthouse on mobile across 37 pages: performance 97-100, other scores 100, first screen in 1.5-1.6 s, CLS 0, 81-90 KB a page.
- The boxes move with CSS transforms. With reduced motion on, they stand still.
A storage warehouse website built around guides in the same way is the Yarus demo in Perm.
