Most eBay migrations go live in one to four weeks. A straightforward store with a clean catalog is at the fast end; large catalogs, custom workflows, or wholesale pricing push toward the slow end. The honest answer depends on four things, and all four are knowable in the first week. Here is the timeline as it actually runs.
The week-by-week timeline
A typical migration breaks down like this:
| Phase | When | What happens |
|---|---|---|
| Discovery | Days 1 to 3 | Catalog audit, workflow walkthrough, platform choice, fixed launch date set |
| Build | Week 1 to 2 | Store built, catalog imported and mapped, design applied |
| Data and integrations | Week 2 to 3 | Customers and order history migrated, shipping, tax, and email tools connected |
| Launch | Week 2 to 4 | Redirects live, payments tested with real orders, credentials handed over |
What makes a migration faster?
A migration is fastest when the catalog is clean and the selling model is standard retail. Under 5,000 SKUs with consistent item specifics, one currency, one warehouse, and no custom pricing tiers is a one-to-two-week move. Sellers who can answer discovery questions quickly save days more; the calendar slips most often waiting on decisions, not on work.
What makes a migration slower?
Three things push a move toward four weeks: catalog mess, custom workflows, and integrations. Tens of thousands of SKUs with inconsistent item specifics need cleanup on the way across. Consignment splits, auctions, breaks, or trade pricing need building rather than configuring. And every system the store must talk to, from shipping software to accounting, adds a connection to set up and test.
Can I keep selling on eBay during the migration?
Yes, and you should. Nothing about your live eBay store changes until the new store is ready, so there is no revenue gap. Most sellers run both channels for a transition period after launch, move repeat buyers to the owned store where margins are better, then wind eBay down on their own schedule.
Why a fixed date matters more than a fast date
The difference between two weeks and four matters less than knowing the date at all. An open-ended agency project drifts; a migration scoped to a fixed price and a fixed launch date in week one is something you can plan inventory, marketing, and cash flow around. That is how we run every move: the date is set in discovery, and that date is what we build to.
