Ecommerce Integrations That Keep Your Entire Operation in Sync

Integrations that keep up when order volume spikes
A list of integration logos doesn’t tell you much. What matters is whether the connections hold up when order volume spikes and whether your team can actually manage them without filing support tickets every week.

Live in Hours, Not Weeks
Authenticate your account, map your SKUs, pull your first orders. That’s the whole process. Most sellers wrap up in one onboarding call. No staging environment. No developer tickets.
Inventory That Doesn’t Lie
Sell a unit on Walmart, and the count changes on Amazon, Shopify, and eBay before another customer can buy a phantom unit. Overselling costs real money and real customer trust. We treat it like the operational failure it is.
Parcel + LTL, Same Engine
Ship a 2-pound box and a full pallet from the same workflow. The rate engine covers parcel carriers and LTL freight side by side, picking the lowest landed cost. If your catalog ranges from small items to bulk inventory, this matters more than you’d think.
No Conglomerate Behind Us
We’re not part of Auctane or any carrier-owned network. The rate engine works for you, not a parent company’s shipping margin. Your negotiated carrier rates stay your rates. Period.
Three Steps to Your First Shipment
Nobody wants a 6-week implementation project. Here’s how it actually goes.
Connect Your Channels
Link your marketplace accounts, ecommerce storefronts, and carrier credentials through standard OAuth and API key flows. Amazon Seller Central, Shopify, Walmart, BigCommerce, eBay. About five minutes per channel, no custom code involved.
Map Your Catalog
Match products across channels by SKU, UPC, or ASIN. The platform pulls in your existing listings, normalizes the inventory counts, and starts syncing. You can set channel-specific stock buffers to hold back inventory on certain marketplaces.
Ship and Scale
Orders land in one queue. AI rate shopping picks the carrier. Tracking automatically pushes back to the originating channel. Purchase orders fire to connected distributors when stock runs low. One screen, not fifteen browser tabs.
Marketplace integrations built for multichannel selling
This covers the bread and butter of multichannel selling: pulling orders, updating inventory quantities, managing listing data, and pushing tracking numbers. We connect to 37 online marketplaces. For Amazon specifically, both Seller Central and Vendor Central are supported as separate integrations, with FBA inventory reconciliation. TikTok Shop and Mirakl-powered marketplaces round out the newer channels, while retail heavyweights like Walmart, eBay, Wayfair, Best Buy, and Home Depot have been in the system for years.

Your storefront deserves a real integration too
Your own storefront is probably the highest-margin channel you sell on, and it usually gets the worst integration from most platforms. Not here. We connect natively to Shopify, BigCommerce, WooCommerce, and Adobe Commerce (Magento), plus 13 more carts. Orders pull automatically. Inventory pushes back in near real-time. Product data moves both ways, so a price update in your catalog appears on the storefront without anyone having to re-key it. For Shopify and BigCommerce merchants, the integration goes deeper: multi-location inventory mapping, variant-level sync, and order-level metadata passthrough for the custom fields your warehouse team relies on at the packing station.
Close the loop from selling to replenishing
Here’s where things get interesting. Almost nobody in this space offers direct distributor integrations. Most multichannel tools stop at the sales channel. They help you sell on Amazon and Walmart, but the moment you need to actually purchase inventory from your suppliers, you’re back in spreadsheets and email chains. Willow Commerce connects to the distributors that matter for electronics sellers: TD SYNNEX, Ingram Micro, D&H, New Age Electronics, and Petra. If you sell medical supplies, Medline and Graham-Field are in here, too. Real-time product availability and cost data feed straight into your catalog. POs can fire automatically when demand forecasting hits a reorder threshold. That closes the loop from selling to replenishing, and it’s not something you’ll find in Cin7 or Brightpearl.

Medical Supply Distributors

PO Automation
Purchase orders can route automatically to the supplier with the best current pricing once reorder thresholds are reached.

Carrier connections built by shipping operators
The people who built our shipping layer spent years at the carrier-executive level at UPS and FedEx. You notice it in how the rate engine behaves. It compares parcel and LTL freight quotes from every connected carrier in real time, then selects the cheapest option that still meets your delivery window. Carrier connections include UPS, FedEx, USPS, DHL, Canada Post, Royal Mail, and Asendia. On the fulfillment side, we integrate with ShipStation, ShipWorks, ConnectShip, and Starshipit, so existing warehouse workflows don’t have to change. If you’re a 3PL or use one, order routing and tracking stay centralized regardless of which facility ships the package.
Parcel + LTL Rate Shopping
Every connected carrier is compared in real time to find the cheapest option that still hits the delivery window.
Independent Routing
No carrier-owned bias. Your negotiated rates remain your rates.
3PL-Friendly Workflows
Order routing and tracking stay centralized regardless of which facility ships the package.
Warehouse Workflow Continuity
Existing warehouse processes can stay in place while carrier logic is unified behind the scenes.

Integration Questions, Answered
Most integrations go live in under an hour through OAuth or API key authentication. The onboarding team can handle catalog mapping and the initial inventory sync with you in the same session.
Yes. They are separate integrations, each built for the specific workflows of that selling model. FBA and FBM are both handled under Seller Central.
It can. Parcel and LTL options show up side by side for every shipment. The engine picks the lowest landed cost that still meets your delivery window.
Connected distributors push real-time availability and cost data into your catalog. Purchase orders are generated automatically when demand forecasting flags a reorder point and route to the supplier with the best current pricing.
No. Fully independent. The rate engine has no routing bias, and your negotiated carrier rates are never marked up by a parent company.
There is a RESTful API with full documentation, and the integration team can scope custom builds for channels or tools not in the standard library.
Stock from all locations rolls into one view, but each sales channel gets location-aware quantity counts. Buffer rules and fulfillment routing can be set per channel and per warehouse.
Yes. 14 days with full access to every integration. Connect channels, run real orders through the system, and test the shipping engine before committing.
