Marketplace Management & Growth
One catalog engine. Every major marketplace.
We help US DTC and wholesale brands sell across Amazon, Walmart, Target Plus, Faire, and TikTok Shop without catalog divergence, inventory stockouts, or channel conflict. You own your seller accounts, your customer relationships, and your brand equity.
// the core model
What is multi-channel marketplace management?
Multi-channel marketplace management is the operational and technical system that allows a brand to list, price, advertise, and fulfill products across external marketplaces, such as Amazon, Walmart Marketplace, Target Plus, and Faire, while maintaining their primary DTC storefront as the central hub of truth.
Most brands fail at marketplace expansion because they treat each channel as a disconnected silo. Inventory sells out on Shopify while Amazon keeps accepting orders, triggering seller penalties. MAP pricing breaks because unauthorized third-party resellers undercut retail prices. Advertising spend is wasted because listing content lacks high-converting A+ assets.
FactoryJet connects your product catalog, inventory feeds, and order management system directly to marketplace APIs. We build automated buffer controls, price-sync state machines, and high-converting storefront creative so you capture incremental revenue without multiplying overhead.

// common questions
Frequently asked questions about marketplace expansion
Topics
Can’t find your answer?
Talk to the founderStrategy & Fit
Will selling on Amazon cannibalize our direct Shopify store sales?
No, when structured properly. Over 60% of US consumers begin their product discovery on Amazon and will not search for independent websites. Marketplace presence captures existing demand that would otherwise go to competing brands, while your DTC storefront retains exclusive bundles, loyalty rewards, and subscription offers.
What is the difference between Seller Central and Vendor Central?
On Seller Central (3P), you sell directly to consumers, set your own retail prices, control your inventory levels, and pay marketplace referral fees. On Vendor Central (1P), you sell wholesale inventory directly to Amazon as a supplier, and Amazon sets the retail price. We primarily help brands succeed on 3P Seller Central for higher margins and price control.
How do we prevent channel conflict and MAP pricing violations?
We establish automated price-syncing rules that match your Minimum Advertised Price (MAP) policy across all channels. We also implement Brand Registry protection to identify and suppress unauthorized gray-market sellers who undercut your retail pricing.
When is a brand ready for marketplace expansion?
A brand is ready when it has proven product-market fit on its core website, stable supply chain capacity, clean barcode/UPC documentation, and trademark registration for brand registry protection.
Inventory & Operations
How does inventory sync between Shopify and Amazon work?
We connect your primary inventory database to marketplace APIs using webhook listeners. When an order is placed on Amazon, stock is decremented in Shopify within seconds. When stock is received in your main warehouse, available quantities update across all channels automatically.
What happens if a product sells out simultaneously on multiple channels?
We configure automated inventory safety buffers (e.g., reserving 5 units of buffer stock). When total warehouse quantity drops to the threshold, marketplace listings automatically switch to zero available stock while your main website continues selling down the final units.
Should we use Amazon FBA, Walmart WFS, or our own 3PL?
A hybrid model is usually best. Using FBA for Amazon Prime badges and WFS for Walmart 2-day delivery badges maximizes conversion rates, while your primary 3PL fulfills direct website and wholesale orders. We architect the inventory distribution model that minimizes storage fees.
How are returns and damaged inventory handled?
Marketplace returns can be routed directly to automated inspection centers or returned to your central 3PL warehouse. We configure automated reconciliation reports to track customer return reasons and identify unfulfillable unit discrepancies.
Can we sell B2B wholesale orders on marketplaces?
Yes. We configure Amazon Business for volume-tiered pricing and integrate with Faire Wholesale to sell to independent boutiques with automated Net 60 invoice settlements.
Channel Specifics
Is Walmart Marketplace worth the investment for a DTC brand?
Yes. Walmart Marketplace is the fastest-growing major US marketplace with less seller saturation than Amazon. Qualifying for the Pro Seller Badge and utilizing Walmart Fulfillment Services (WFS) allows established brands to capture substantial incremental volume with lower CPCs.
How difficult is it to get approved for Target Plus?
Target Plus is invitation-only. Acceptance requires proven brand equity, US incorporation, GS1-certified UPC barcodes, and Direct Vendor Ship (DVS) EDI compliance. We assist qualified brands in preparing their formal submission packages.
How does TikTok Shop integrate with our existing e-commerce stack?
We connect TikTok Shop directly to your product catalog, allowing in-app checkout while routing orders to your central warehouse for fulfillment. We also configure affiliate commission structures for creator promotion.
Can we sell internationally on European or Asian marketplaces?
Yes. We support cross-border expansion to Amazon Europe (UK, Germany, France), Mercado Libre in Latin America, and regional marketplaces with automated currency conversion, VAT compliance, and translated catalog feeds.
What is Amazon Brand Registry and why is it mandatory?
Amazon Brand Registry gives trademark owners access to enhanced A+ Content, customized Storefronts, Sponsored Brands video ads, and Project Zero counterfeit protection tools. We ensure your brand registry assets are fully active.
Pricing & Handover
Do you charge a percentage of our marketplace sales?
No. Unlike traditional agencies that charge 5% to 10% of gross marketplace revenue forever, FactoryJet works on transparent, fixed-price project milestones and optional flat-fee advisory retainers. You keep 100% of your margin.
Who owns the marketplace accounts and advertising data?
You own 100% of your Seller Central accounts, advertising dashboards, and brand tokens. We operate via delegated partner permissions and never hold your business assets in proprietary agency accounts.
How long does a multi-marketplace setup take?
A standard 3-channel rollout (Amazon + Walmart + Faire) typically takes 3 to 4 weeks from scoping to live catalog dispatch and advertising activation.
What happens after the initial build and launch?
We provide comprehensive documentation, video walkthroughs, and standard operating procedures (SOPs) for your in-house team, with 30 days of post-launch hypercare support and optional ongoing advisory retainers.
