Sell on Amazon, eBay, and Your Own Website From One Dashboard

The Walkthrough
Step 1: Sign Up for BigCommerce
What to do: Go to BigCommerce and start your free trial. Choose the plan level based on your annual revenue — Standard works for most businesses starting multi-channel selling.
Why you’re doing it: BigCommerce has native multi-channel integrations built in, not as paid add-ons. Connect Amazon, eBay, Facebook, Instagram, Google Shopping, and your own storefront from one dashboard with synchronized inventory.
What to expect: 10 minutes for account creation. The setup wizard walks you through the basics.
Common mistakes: Starting on the most expensive plan. Standard ($39/mo) supports multi-channel selling. Only upgrade when you hit the revenue thresholds.
Step 2: Build Your Store and Add Products
What to do: Choose a theme, customize your branding, and add your product catalog. For each product, include title, description, price, weight, dimensions, photos, and SKU. The SKU is critical — it’s how BigCommerce tracks inventory across channels.
Why you’re doing it: Your product catalog is the central database that feeds every channel. Get it right here and it flows correctly to Amazon, eBay, and everywhere else.
What to expect: Time varies by catalog size. Budget 2–3 hours for 20–50 products. Use AI to batch-write descriptions.
Step 3: Connect Your Sales Channels
What to do: Go to Channel Manager in your BigCommerce dashboard. Click “Add Channel” and connect Amazon, eBay, Facebook/Instagram, and Google Shopping one at a time. Each requires you to log into your existing seller account on that platform.
Why you’re doing it: This is the magic step. Once connected, your inventory syncs automatically. Sell one unit on Amazon? BigCommerce updates the count on eBay and your website instantly.
What to expect: 30–60 minutes per channel for initial connection and mapping. Amazon is the most complex; Google Shopping is the simplest.
Common mistakes: Not mapping product categories correctly during channel setup. Take time to match your BigCommerce categories to each channel’s taxonomy — it affects search visibility on those platforms.
Step 4: Set Channel-Specific Pricing and Descriptions
What to do: For each channel, review and adjust pricing (Amazon fees differ from eBay fees — your margins need different pricing), and customize product descriptions. Use AI: “Rewrite this product description for Amazon. Use bullet points, focus on keywords buyers search for, and keep it under 200 words.”
Why you’re doing it: Each channel has different buyer expectations and algorithms. What works on your website doesn’t necessarily work on Amazon. Optimized listings per channel = more visibility = more sales.
What to expect: 1–2 hours to customize your top 10–20 products per channel. The rest can be updated over time.
Step 5: Set Up Order Management
What to do: In BigCommerce, go to Orders. All orders from every channel flow into one unified inbox. Set up email notifications for new orders and configure your shipping settings.
Why you’re doing it: One place to see every order, regardless of where it came from. No more checking Amazon Seller Central, then eBay, then your website dashboard separately.
What to expect: Orders start flowing in as soon as your channels are live. Fulfillment is managed from the single BigCommerce dashboard.
Confidence Level
This workflow is Beta — Based on Best Available Knowledge. BigCommerce is an established e-commerce platform with well-documented multi-channel features. Setup complexity increases with the number of channels and products.
What to Do If It Doesn’t Work
- Inventory not syncing: Check that your SKUs match across all channels. SKU mismatches are the #1 cause of sync failures.
- Amazon listing rejected: Amazon has strict listing requirements. Review their category-specific guidelines for titles, images, and descriptions.
- Orders not appearing: Verify the channel connection status in Channel Manager. Disconnect and reconnect if needed.
