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. When a coin is on the register — even before you complete the sale — it is not for sale on ExtraCoins, eBay, wholesale, auction, or connected Shopify, Square, Woo, or BigCommerce.
| Where | Website | Who buys | How it prices | SpotPro fees |
|---|---|---|---|---|
| ExtraCoins | yourname.extracoins.com or your own domain | Collectors / public | Full website with twelve designs; fixed retail (bullion and Goldbacks 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.
Last piece on the register
One sale, one unit, no apology. Add it to Sales Checkout and it comes off ExtraCoins, eBay, wholesale, auction, and connected storefronts right then. Take the line off the ticket and those listings come back. Complete the sale and they stay sold. Lots that already have bids stay live — ExtraCoins still will not sell that piece.
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.) A coin on Sales Checkout is already off those surfaces — even before Complete Sale. Take the line off and the listings come back. Help: Last piece on the register. Members path: Sell online → Marketplaces — Connect eBay (or Save & test on the others), Import catalog or Link by SKU, then sync. To list a SpotPro coin onto eBay without retyping it: load shipping/payment/return policies (those are created on eBay), then Current Inventory → List on eBay. Seller desk: Sell online → eBay. Buy It Now or timed auction. Bullion follows live metal about every 5 minutes until someone bids. How-to: List coins on eBay. 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: Sell online → 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. Buy It Now stays current. Timed eBay auctions with no bids keep starting bid and Buy It Now in step with metal (and a floor if you set one). 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 Sell online → 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.
