Pick two marketplaces, list on the stricter one first, copy the listing to the second instead of retyping, tag items with a stock code, and set up delisting before you add a third marketplace. You can do the setup in an afternoon.
The shortcut: OctoResell is a Chrome extension that copies a listing to your other marketplaces, fills each form for you and removes sold items from the rest. Free for 5 fills a day.
Add to Chrome, freeUpdated October 2026. OctoResell is a Chrome extension (it also works in Brave and Edge) that copies a listing to the other marketplaces, fills each form for you, and removes sold items from your other listings.
Step 1: pick two marketplaces, not four
More marketplaces means more delisting and more rules to remember. Start with two that suit your items, then add a third once delisting feels easy. Where to sell what helps you choose.
Step 2: set up accounts and payouts first
- Finish seller verification, payout details and addresses on each marketplace before your first listing. Some ask for a phone number or address and will stop you mid-listing otherwise.
- Stay signed in to each marketplace in the same browser. OctoResell uses your existing sign-ins.
Step 3: list once, then copy
- Write the full listing on the marketplace with the tightest limits. Include brand, size, condition and measurements.
- Open that listing and click Import to OctoResell.
- Press the second marketplace in the card. Its form opens in a new tab, filled in.
- Check the checklist, then press that marketplace’s own post button.
Step 4: make every item findable
Add a short stock code to each title or SKU, and keep a simple list of what is where. OctoResell keeps an inventory in your browser that you can search and export to CSV, so you do not need a separate spreadsheet to start.
Step 5: decide how sold items come down
This is the part to settle before you scale. You can delist by hand or automatically. OctoResell checks linked listings every 15 minutes while your browser is open and asks before it removes anything.
What it really saves
Listing the same item twice by hand takes several minutes each time. A fill takes seconds, plus a quick check. The saving grows with each item and each extra marketplace, and it is not zero effort: you still check every form and press post.
Questions
Can I sell the same item on multiple platforms?
Yes, and many resellers do. The risk is a double sale, which you manage by delisting quickly. Is crosslisting allowed?
How many marketplaces should I start with?
Two. Add a third when delisting is routine.
Do I need to retype the listing for each marketplace?
No. Import the finished listing and fill the other marketplace’s form.
What if I sell on a marketplace OctoResell does not support?
OctoResell supports eBay, Poshmark, Mercari, Depop, Etsy, Vinted and Facebook. Others are not covered yet.
