Help & support

After you sign in, open Connect eBay and add an account. eBay's own sign-in page opens; sign in there and approve SellLynx. Repeat for each account. SellLynx never sees your eBay password.

As many as you run. Every page has an account filter, and most show all accounts together by default.

It depends on how many listings the account has; accounts with tens of thousands of listings take longest. You can keep using SellLynx while it runs.

Yes. The demo store runs the real pages with five made-up eBay accounts. Nothing you do there is saved.

We're inviting sellers in small groups. Request early access and we'll email you when there's a spot.

No. Every change is shown next to what's live on eBay, and nothing is sent until you confirm. Each listing is re-read on eBay right before it changes, then read back afterwards to confirm the change went through.

SellLynx shows eBay's reason next to the listing, for example a missing required item specific or a policy eBay rejected. Fix the field it names and send the change again.

UPCs have a check digit, and SellLynx checks it before sending to eBay. Copy the full number from the box; a 13-digit code with a leading 0 is fine. If the product has no UPC, leave the field empty.

Listings with the same SKU on different accounts are linked. When one sells, SellLynx lowers the quantity on the linked listings by the same amount and records what it changed under Inventory.

From eBay's own financial records for each order: the sale, eBay fees, promoted listing ads, shipping labels and refunds. Add your item cost (one at a time or by spreadsheet) to see true profit; until then SellLynx can estimate cost as a percentage you choose.

When you buy several labels in one go, eBay sometimes charges them as one amount. SellLynx splits that charge across the orders shipped at the same moment and marks those labels as estimated.

eBay charges fees and labels right away but can hold sale money until the buyer receives the item. Available goes negative when charges arrive before held money is released; it evens out as holds clear.

Yes. Messages shows every account's conversations in one inbox. Replies go out through eBay's messaging, and your sent messages from eBay are loaded so you see the whole conversation.

In your Account settings, turn on two-step sign-in and scan the code with an authenticator app. Save the recovery codes somewhere safe.

Use Forgot password on the sign-in page. We'll email a reset link to the address on your account.

Open Connect eBay and disconnect the account there. You can also remove SellLynx's access from your eBay account settings.

Your listings, orders, messages and financial records from eBay, kept in your own workspace so the tools can work. See the Privacy Policy for details.
