For card shops · eBay
List on eBay from the stock you already hold.
Publish singles to your own eBay account straight from inventory. The listing holds that unit until it sells or you end it, and when it sells the order comes back and settles against the right card — so your stock count and your eBay store never disagree.
Exactly what it handles
| Action | Direction | What happens |
|---|---|---|
| Publish from inventory | TCG OS → eBay | Build the listing from a unit you already hold and publish it to your own connected eBay account. Availability is re-checked immediately before the first eBay write, so a card sold at the counter thirty seconds ago cannot be listed. |
| Reserve the unit | Internal | The unit is committed only once eBay confirms a live listing exists. If publishing fails partway, the listing goes to an error state and no stock movement is recorded — the card stays available. |
| Revise a live listing | TCG OS → eBay | Change price or details on a published listing without ending and relisting it. |
| Best Offers | eBay → TCG OS | Live listings with Best Offer enabled are polled and each new offer raises a notification, because offers expire in about 48 hours and nobody can watch eBay all day. Offers are never stored — only the fact that one arrived. |
| Order ingestion | eBay → TCG OS | Orders are polled, matched to the listing that sold, and settled automatically into a sale against the right unit. Replaying the same order is a no-op, so a re-poll never double-counts. |
| End a listing | TCG OS → eBay | Ending returns the unit to availability, ready to be allocated somewhere else. |
The stock rule
A unit sits on exactly one channel at a time. Moving it to another channel reassigns it rather than copying it, which is what makes overselling impossible — a card allocated to a show cannot also be sold on eBay. A live eBay listing must be ended before its unit can be moved.
That is a stricter guarantee than syncing quantities between systems, and it is stricter on purpose. Nothing has to be reconciled after the fact, because the card was never in two places to begin with.
What it does not do
- Orders are settled in GBP. A non-GBP order is skipped rather than converted at a rate we would be guessing at, and logged for you to handle.
- Orders for listings we did not create are ignored. If you sell other things on the same eBay account, those sales are simply not ours to settle — that is normal, not an error.
- An order arriving for a listing you already ended is skipped for a human to look at. You have already returned that stock to availability, so auto-settling it would take stock you have.
- A unit with a live eBay listing cannot be moved to another channel. End the listing on eBay first — we will not silently withdraw a listing a buyer might be watching.
- Cancellations and returns are not automated. They are a real reversal of stock and money, and a person should decide how to handle each one.
eBay integration FAQ
- Will connecting eBay change my existing listings?
- No. Listings you already have stay exactly as they are — connecting your account does not import, edit or take over anything. Only listings published from your inventory here are tracked, and only their orders are settled.
- Can a card be listed on eBay and sold in the shop at the same time?
- No, and that is the point. A unit sits on exactly one channel at a time. Moving it to another channel reassigns it rather than copying it, which is what makes overselling impossible — a card allocated to a show cannot also be sold on eBay. A live eBay listing must be ended before its unit can be moved.
- Whose eBay account are the listings on?
- Yours. You connect your own eBay seller account, the listings are yours, the buyer relationship is yours, and eBay bills you for its own fees directly. We do not resell or intermediate.
- What happens if a listing fails to publish?
- It stays as a draft or moves to an error state with the reason attached, and no stock movement is recorded. Inventory is only ever committed once eBay has confirmed the listing is live, so a failed publish cannot quietly consume a card.
- Do you take a cut of eBay sales?
- No. The TCG OS charges its flat monthly subscription and nothing per sale. eBay charges its own fees, and those are between you and eBay — we are not in a position to change or waive them.
Try it with a handful of listings.
Publish a few cards, watch one sell, and check the order against your stock before you move anything else across.
