Selling on Amazon is a fantastic way to build a business, but let’s face it—the supply chain behind it can feel like a puzzle with a few missing pieces. From sourcing products to getting them delivered, there’s a lot to manage if you want to keep things humming along. In this guide, we’ll break down the Amazon supply chain step-by-step and spotlight how Ailumia’s SellerHub tools—Product Management, Purchasing Management, Warehouse Management, and FBA Management—can give sellers a leg up. No pressure to dive in, just some practical insights to make your life easier.
Breaking Down the Amazon Supply Chain
Amazon’s supply chain is a slick operation, built to deliver speed, scale, and that customer-first vibe we all know. It flows through a few key stages: sourcing and manufacturing, inventory management, and order fulfillment. As a third-party seller (you’re in good company—over 60% of Amazon’s sales come from folks like us), you’ve got a big role in keeping this engine running. Here’s how it works.
- Sourcing and Manufacturing
It all kicks off with finding products and getting them made. You’re picking suppliers—sometimes halfway around the globe—and juggling production timelines. Quality’s gotta be solid, and lead times need to line up, or you’re stuck waiting.
- Shipping to Amazon
Next, your products need to hit Amazon’s fulfillment centers if you’re using Fulfillment by Amazon (FBA). This means dealing with customs, freight, and nailing Amazon’s picky packaging and labeling rules. A hiccup here can throw everything off.
- Inventory Management and Warehousing
Once your goods land in Amazon’s warehouses, it’s about keeping stock in check. Too little, and you miss sales; too much, and you’re hit with storage fees. Plus, with Amazon’s newer capacity limits, you’ve got to be strategic about what you send.
- Order Fulfillment
A customer clicks “buy,” and Amazon’s team takes over—picking, packing, and shipping from the nearest center. For FBA sellers, this part’s a breeze, but only if your inventory’s in place.
- Delivery and Customer Satisfaction
Finally, your product lands on the customer’s doorstep, often with Prime’s two-day magic. Happy customers mean great reviews and repeat buys, so keeping this step smooth is clutch.
Amazon handles the fulfillment end with FBA, but you’re the one steering sourcing, shipping, and inventory. That’s where Ailumia’s SellerHub tools come in—they’re built to lighten the load without making it feel like a chore.

How SellerHub Ties It All Together
SellerHub’s tools don’t just work solo—they sync up to create a seamless supply chain flow from sourcing to delivery. Each piece connects the dots, tackling bottlenecks and turning chaos into a well-oiled machine. Here’s how they team up at every stage:
- Sourcing and Manufacturing: Product Management acts like your sales radar, pinpointing top-performing SKUs and flagging what’s trending so you know what to double down on. Purchasing Management jumps in to turbocharge the process—streamlining supplier orders with quick POs and cutting delays. Say a bamboo cutting board starts flying off the virtual shelves: Product Management spots the surge, Purchasing Management locks in the reorder, and your supplier’s on it before demand outpaces supply.
- Shipping to Amazon: Warehouse Management keeps your pre-FBA stock lean and cost-effective, staging inventory in your own space until it’s go-time. Then FBA Management takes the baton, ensuring shipments hit Amazon’s fulfillment centers without a hitch—labels perfect, packaging on point. Customs snarls or freight hiccups? The tools help you plan ahead, keeping your goods moving smoothly to avoid costly holdups.
- Inventory Management: This is where Warehouse Management and FBA Management shine as a duo. Warehouse Management tracks your in-house stock with precision, letting you store bulk affordably and dodge Amazon’s steep fees. Meanwhile, FBA Management keeps tabs on what’s in Amazon’s warehouses—stock levels, sales velocity, restock alerts—so you’re never caught short or drowning in overstock. Together, they strike the sweet spot: enough inventory to sell strong, not so much you’re bleeding cash on storage.
- Fulfillment and Delivery: With your stock locked and loaded, Amazon’s fulfillment engine hums—picking, packing, and shipping at lightning speed. Customers get their orders (often in two days with Prime), leave glowing reviews, and come back for more. SellerHub’s prep work behind the scenes—ensuring inventory’s in place and ready—makes this final win possible, turning smooth logistics into a competitive edge.
The magic lies in how these tools talk to each other. Data flows between them, so a hot seller flagged in Product Management triggers a PO in Purchasing Management, preps stock in Warehouse Management, and lands flawlessly in FBA Management. It’s less work for you, fewer fumbles, and a supply chain that feels less like a juggling act and more like a victory lap.
A Real Seller Story: From Chaos to Cash
Meet Hexai, a small retailer headquartered in Kowloon, Hong Kong, selling everyday essentials on Amazon—think disposable ice cream cups, colorful envelopes, and kitchen storage trays. Launched in 2018 by a duo passionate about affordable household solutions, they’d gained traction with party planners and home organizers alike, but by mid-2023, they were hitting snags. Sporadic shipments from their supplier in China left them scrambling, overstocked FBA inventory racked up $10,100 in monthly fees, and a summer sale stockout of their best-selling 9 oz pastel cups cost them $14K in missed revenue. They were spinning their wheels—until SellerHub helped them regain footing. Here’s how it unfolded:
- Product Management Zeroed In: Matican used the tool’s analytics to pinpoint their 9 oz ice cream cups and envelope sets as the stars, driving 70% of their $300K monthly revenue, while niche items like glittered gift tags lagged. They ramped up production on the winners and culled the slow movers, sharpening their focus.
- Purchasing Management Slashed Delays: By streamlining POs and syncing with their supplier, they trimmed lead times from 45 days to 36—a 20% gain. The steady orders landed them a 5% discount on cup shipments, saving $380 per batch.
- Warehouse Management Saved Cash: They secured a compact Houston warehouse for $650 a month, shifting bulk stock there and cutting FBA fees by 15% (down to $935). A quality check caught a batch of leaky ice cream cups before shipping, avoiding a 50-return pileup.
- FBA Management Boosted Uptime: With restock alerts set to a 28-day supply, their in-stock rate soared to 98%. During the 2024 back-to-school rush, those pastel cups stayed available, netting an extra $26K they’d lost the year before. Reviews climbed from 4.3 to 4.6 stars as deliveries hit their mark.
Six months later, the numbers told the story: revenue climbed 30%, from $200K to $500K a month. Reviews improved as deliveries hit their mark, and they had breathing room to test new products without risking the farm. It wasn’t overnight magic—it was SellerHub giving them the tools to fix leaks and scale smart. For a small outfit, that’s the difference between surviving and thriving on Amazon.
