No double-selling
Putting a coin on auction does not lock it by itself. Once someone bids — or you put it in a live show — that stock item is held so the counter and website cannot sell it again.
How you sell
Website · Wholesale · Auction — same stock as at the counter
You should not have to keep three different lists. SpotPro uses one count for the case, the website, other dealers, and the auction floor.
| Where | Website | Who buys | How it prices | SpotPro fees |
|---|---|---|---|---|
| ExtraCoins | yourname.extracoins.com | Collectors / public | Fixed retail (bullion can follow spot); optional in-store only showcase listings (web visible, no cart) | $0 list / $0 sell commission from SpotPro |
| Coin Dealer X | coindealerx.com | Other dealers (vetted) | Fixed wholesale | Included for eligible members — no SpotPro GMV take |
| CDX Auction | cdxauction.com | Public and dealers | Bidding and live shows | Members: $0 list / $0 platform FVF; buyer pays you |
After the sale — one ops desk
Remote sales from every channel land in SpotPro — not three separate inboxes. Money & status on Orders, pack & labels on Ship Desk, buyers on Customers.
Website notices
If an auction item is live, the ExtraCoins product page can say so and point people to bid instead of buying fixed price.
Ship Desk for every channel
Paid ship orders from ExtraCoins, CDX Auction/Live, and wholesale pack on one desk — buyer groups, rates, labels, packing slips. Local pickup stays on Orders / the register.
One customer book
Same buyer email across store, auction, and wholesale = one card with channel badges and history — not three CRM tabs.
Sold out elsewhere
If the last one sells in the store or wholesale before any bid, open auctions with no bids can close so you are not stuck with a dead listing.
Money comes to you
Buyers pay your shop — card, Zelle, wire, pickup, and the methods you already use. We are not holding the buyer’s money as a middleman escrow. Your customers and prices stay yours — SpotPro is not a multi-dealer marketplace of other shops on your page (you stay the shop).
Integrations — import your catalog, one stock book, seven selling surfaces
SpotPro does not replace eBay or Shopify. Those sites stay your public storefronts. SpotPro is the shop system underneath: counter sales, inventory, sell prices, and packing for remote orders. Pure marketplace or cart software is built for online traffic — not for a coin shop’s buy desk, case stock, live metal prices, and auction holds.
Already have years of eBay (or Shopify) listings? Connect the API, then use Import catalog → SpotPro. Matching SKUs link to existing inventory; missing SKUs become new SpotPro items. Your marketplace listings stay live — you do not recreate thousands of listings. After import, SpotPro is the hub for stock, sell prices, orders, cancels, and ship tracking.
SpotPro’s own lanes are ExtraCoins (web store) and CDX Auction (public bidding). On top of that you can connect all five external marketplace APIs. Same SKU can appear on:
- ExtraCoins storefront
- CDX Auction
- eBay
- Shopify
- Square
- WooCommerce
- BigCommerce
That’s seven selling surfaces, one inventory count. (Coin Dealer X wholesale is an eighth dealer-to-dealer lane when you use it.) Members path: Ecommerce → Marketplaces — Save & test, Import catalog or Link by SKU, then sync. Metal prices update about every 5 minutes (spot + your premiums; eBay only when there are no bids). Online metal protection can set available qty to 0 on linked listings when the tape is protected, then restore SpotPro qty.

SpotPro becomes the hub: import your existing marketplace catalog (no forced recreate on eBay/Shopify), then stock and sell prices push out, paid orders come in, cancels restock, and shipping tracking goes back out. Metal sell math stays hub-driven (spot + your premiums). How to do it: Help Center step-by-step (Save & test → Import catalog or Link by SKU → Sync qty / prices / Orders ↔) · Members: Ecommerce → Marketplaces.
All five APIs, not “pick one”
You can connect eBay and Shopify and Square and WooCommerce and BigCommerce at the same time. Same barcode/SKU can be linked on every channel you turn on.
Live price updates (spot-linked)
When gold and silver move, SpotPro can update sell prices on linked listings from your live spot + premiums — about every 5 minutes on a schedule, or on demand. Elsewhere, multi-channel price automation is often a separate paid connector or “enterprise” module; here it’s part of Marketplaces for connected platforms. eBay never auto-revises a listing that already has bids.
Market-hours pause on external listings
Same Online Pricing protection that covers ExtraCoins checkout and Auction spot Buy Now also protects linked eBay/Shopify/Square/Woo/BigCommerce stock: while protection is active (stale/down feed, or U.S. session closed in conservative mode), SpotPro sets available qty to 0 on in-scope linked listings (on-hand unchanged). When the tape is live again (or the session reopens), real qty is restored. SpotPro cannot turn off those platforms’ checkout — qty 0 is the purchase block.
External sales land in SpotPro
Paid marketplace orders are imported into Ecommerce → Orders and Ship Desk. Stock drops once; remaining qty updates on every other linked channel. Pack and label like ExtraCoins.
Qty sync, webhooks, schedule
On-hand qty stays aligned after sales. Optional order webhooks for near-real-time import; prices ~every 5 minutes; order pull ~every 10 — or Sync orders now / Update prices anytime.
