Amazon FBA Inventory Tracking: How to Get Central Visibility

If you’re using Amazon FBA to handle storage and fulfillment, a lot of the operational burden is off your shoulders as Amazon packs, ships, and even handles customer service.

But here’s the catch, while Amazon knows exactly how much stock is left in its warehouses, you don’t automatically have that visibility.

That means you could be selling products on Shopify without realizing FBA stock is low (or even sold out).

And when you’re juggling multiple sales channels, this blind spot can quickly spiral into overselling, delays, and unhappy customers.

The solution?

Centralized visibility that brings everything into one dashboard.

Why Sellers Need a Unified View of Shopify + FBA

When Shopify and Amazon FBA live in separate dashboards, you never get the complete picture of your inventory.

That creates blind spots that directly affect sales, cash flow, and customer experience.

A unified dashboard solves this by showing your stock across both platforms in one place.

Here’s why visibility is so important if you’re running a Shopify store alongside Amazon FBA:

• Prevent overselling on Shopify
  If your Shopify store shows an item as “available” but Amazon has already run out, you risk taking orders you can’t fulfill. That means refunds, frustrated customers, and negative reviews.

• Plan smarter restocks
  Without clear visibility of your FBA inventory, you’re stuck guessing when to reorder. Real-time tracking lets you see which products are running low so you can restock before sales stall.

• Make better business decisions
  Inventory is cash. If you don’t know what’s sitting in Amazon warehouses, you can’t forecast sales properly or manage cash flow effectively.

• Save time and reduce errors
  Logging into multiple dashboards and juggling spreadsheets just to know your stock levels isn’t scalable. Having everything in one place frees up hours of manual work.

What Makes Managing Shopify + FBA Inventory Hard

On the surface, managing inventory across Shopify and Amazon FBA seems straightforward, you just need to know what’s available and where.

But in practice, sellers quickly run into obstacles that make it much harder than expected:

Here are the most common challenges:

• Two platforms, two systems: Shopify and Amazon each have their own dashboards, rules, and data formats. You’re constantly switching contexts to piece things together.
• Different identifiers: Shopify organizes products by SKUs and variants, while Amazon uses ASINs and FNSKUs. Without proper mapping, your data never lines up.
• No real-time connection: Shopify doesn’t automatically pull in FBA inventory, meaning stock levels are often incomplete or outdated.
• Multiple stock states in FBA: Amazon splits inventory into Available, Reserved, and Inbound. Shopify doesn’t reflect these distinctions, leaving you blind to what’s truly sellable.
• Reporting delays: Exporting reports from Seller Central or Shopify takes time, and by the time you merge them, your numbers may already be wrong.

Approaches Sellers Use (and Why They Fall Short)

To get a grip on their inventory, most Shopify and Amazon sellers try a few different methods. While each can work at a small scale, they all start to break down as sales and SKUs grow.

1. Manual Spreadsheets

Many sellers start by downloading reports from Shopify and Amazon, then merging them in Excel or Google Sheets.

• ✅ Pro: Free and simple for a very small catalog.
• ❌ Con: Time-consuming, error-prone, and always outdated by the time you finish.

2. Basic Integration Tools

Some apps attempt to connect Shopify and Amazon, syncing quantities or exporting data between platforms.

• ✅ Pro: Faster than spreadsheets, requires less manual work.
• ❌ Con: Usually surface-level; they don’t give meaningful analytics.

3. Centralized Inventory Software (Best Option)

Dedicated inventory management platforms such as Sumtracker connect Shopify, Amazon, and other channels into one unified dashboard.

• ✅ Pro: Real-time visibility, reporting, alerts, and restock planning, all in one place.
• ❌ Con: Paid subscription, but far more efficient and scalable than the other options.

Conclusion

Selling on both Shopify and Amazon FBA is one of the fastest ways to grow your eCommerce business but it comes with a major challenge i.e., visibility.

Shopify shows you what’s in your direct control, Amazon shows what’s in their fulfillment centers, but neither gives you the complete picture.

That gap leads to overselling, late restocks, messy spreadsheets, and constant dashboard-hopping.

The fix isn’t more manual work, it’s a single dashboard that unifies both Shopify and Amazon FBA inventory in real time.

With a centralized system like Sumtracker, you can finally stop guessing and start managing with clarity.
