One Stock Count for Every Channel

One pile of stock. A separate number for every channel.

Multichannel inventory management software built on one warehouse count per product. Each store or marketplace gets its own listing, with its own SKU and its own rules for how much of the pile it sees.

Three selling problems, in the words of the people who raised them.

And what we built for each one.

"...the On Hand Inventory isn't accurate. It is still reflecting all the product that has already shipped out."Ecommerce Executive, Graeter's Ice Cream
What we built: the stock screen keeps on hand, assigned and available as three separate counts. Each store gets the available number, not the raw one.
"This is all manual at the moment. No automated cost averaging, no purchase orders, just manual adjustments to products."Operations Manager, Trading Card Retailer
What we built: a Convert to Pack action that breaks a sealed box into packs and carries the cost with it. Each pack size on a store is a kit drawn from the same count, so every listing updates.
"There were 199 products that didn't have barcode in Shopify at all. I had to generate barcodes for them manually..."Engineer, SkuNexus
What we built: UPC, EAN, GTIN and MPN live on each listing, and a product's Integrations tab shows what every store holds, with Push and Pull for a single product.

One product, many listings.

A product is the thing on your shelf. A listing says it's for sale on one channel, under that channel's own SKU. Sell one blue widget on three sites and all three read the same count.

  • Own channel SKU per store, mapped to your SKU
  • An Enabled switch pauses one channel and leaves the rest alone
  • Nothing to delete: archive a listing and restore it later
Graeter's pushes stock to more than one Shopify location, so each location carries the stock that sits there.

One channel listing opened, with its channel SKU, Enabled switch and the stock rules for that channel

Set the rules for each channel.

On each listing you can hold units back, cap what gets sent, or reserve a pool. With 100 in the warehouse, Shopify can see 100, Walmart 50 and BigCommerce 90.

  • Safety stock, inventory cap and reserve pool per listing
  • Allocation priority per listing
  • Option to never send a negative number
Stock rules for one channel listing: safety stock, inventory cap, reserve pool, share of stock sent, a stock minimum and a never-go-negative setting

Match each store location to your warehouses.

Tell SkuNexus which store location lines up with which warehouse. Stock from the warehouses you pick adds up and goes to that location. No mapping, no push.

  • Send the exact count or only the change since the last sync
  • Last 25 syncs on screen, with the error if one failed
  • Trigger a sync by hand for orders, products or stock

Multi-channel order management: every channel in one order list.

Orders from every channel land in one list. When a unit sells anywhere, the shelf count drops once and every listing works out its new number from it.

  • One order list for every store and marketplace
  • The last 25 syncs of each connection on screen, with the error if one failed
  • A sync by hand for orders, products, stock or customers when a store has had a bad day
All orders list with a mix of statuses and orders from Shopify, BigCommerce and WooCommerce

Sell a single, a 2-pack and a bundle from one pile.

Each pack size or bundle is a kit built from your base products, so every listing shows how many complete packs you can really ship.

  • Pack sizes as kits on one stock count
  • Available packs worked out from the singles
  • Kits listed on any channel like any product

A 2-pack set up as a kit with one part at quantity 2: 280 single units on the shelf make 140 complete 2-packs available
Customer story · Graeter's Ice Cream

A new storefront. The warehouse side didn't change.

Graeter's moved from Magento to Shopify in 2025. We built a Shopify connector layer on top of the batching and stock setup they already ran. It splits one order into several, sends tracking and cancellations back to the right shipment, and syncs address and gift-message edits. Integration work took about four months.

What changed
  • The storefront changed, the stock and batching setup stayed
  • One multi-address gift order becomes several orders, each shipped on its own
  • Tracking and cancellations go back to the right Shopify shipment

Works with what you already use.

Shopify, BigCommerce, Adobe Commerce and Shopware run live at SkuNexus customers today. WooCommerce and Walmart have working connectors. Using something else? Ask on the call and we'll tell you what it takes.

    We connect each store, map its locations to your warehouses, set the cap or reserve for each channel and bring over your products and stock.

  3. Go-live
    About 9 weeks to 6 months

    Recent launches took from about 9 weeks to about 6 months from kickoff, depending on how much was built. Cutover is planned with you for one window.

Questions buyers ask us

Can I sell one product on several stores?

Yes. One product, one stock count, and a listing for each store. Each listing has its own channel SKU.

Can I send less stock to one channel?

Yes. Set a safety stock, a cap or a reserve pool on that listing. The other channels are not affected.

How do I pause one channel?

Turn the Enabled switch off on its listing. Stock stops going to that channel. The others carry on, and your warehouse count does not move.

Do Amazon and eBay connect?

Yes. SkuNexus has connectors for both, so Amazon and eBay orders land in the same order list as your own stores.

Can I sell a 1-pack, 2-pack and 10-pack from one pile?

Yes. Each pack size is a kit built from the base product. Selling a 10-pack draws 10 units from the same count.

Which stores and carriers does it connect to?

Shopify, Shopify POS, BigCommerce, Adobe Commerce and Shopware for stores, Amazon and eBay for marketplaces, and UPS, FedEx and USPS for labels. Systems without a ready connector are built against the open API. See the full list of integrations.

How is SkuNexus priced?

Pricing is scoped on the call, based on your order volume, channels and warehouses. See pricing for how scoping works.
