A UK van and truck parts seller with 12,000 SKUs, six years of Linnworks history and no appetite for downtime. The move happened over one weekend.
Nothing was broken enough to stop trading. Everything was slow enough to cap how fast the catalogue could grow.
Linnworks held the catalogue and Linnworks alone decided what was in stock. ShipStation printed the labels. Every question that crossed the two — why did this oversell, where is this parcel — was answered by hand.
Van and truck parts only sell if the buyer can confirm they fit. Building eBay Motors compatibility meant assembling vehicle lists SKU by SKU — the single biggest brake on listing new stock.
Order history, supplier pricing, channel mappings and open purchase orders had accumulated since the business started. A migration that lost any of it was not a migration.
“We had 12,000 SKUs on eBay UK, six years of Linnworks data, and zero appetite for downtime. Huup migrated us between Friday night and Sunday morning. We didn't lose a single order.”
“We sell trim and body parts for vans. Before Huup, building eBay Motors compatibility was a 2-hour job per SKU. Now one click does 8 vehicles, and equivalents catch parts I'd never have listed.”
The catalogue, the stock pool, the orders and the supply chain now live in the same place — and the two subscriptions that used to hold them are gone.
Friday night to Sunday morning, with orders still flowing. No downtime was scheduled and none was needed.
Fitment is applied from the vehicle database instead of assembled by hand, and equivalent-part matching surfaces vehicles the team would not have listed manually.
The same product graph and the same stock pool feed every channel. Adding a channel is a connection, not a second catalogue to maintain.
Stock changes propagate to every connected channel as they happen, so the number a buyer sees is the number in the warehouse.
Six vendor partners and four dropship suppliers are routed from the same orders workspace — the warehouse and the supplier see the same task list.
Linnworks and ShipStation were both retired. The operation runs on a single platform with a single bill.
“We've been with Huup for a year. Sales replies in under an hour, support answers in real time on Slack. The team feels like an extension of ours — we ping them and we ship.”
