I was sitting in the audience during Amazon's Smarter FBA Inventory Management with Seller Assistant session at Amazon Seller Growth Summit in New York on July 16^th when a seller asked a question I've heard countless times before:

"Will we ever be able to download the Inventory Forecast report?"

The Amazon presenter answered that sellers should expect a download option beginning in August.

It wasn't part of the presentation itself. It came up during the Q&A, and as of this writing, Amazon hasn't published a formal announcement or updated its Seller Central documentation. After the session, I checked both and couldn't find any public references for the feature.

So, while the timing could still change, it's a noteworthy update—and one that many sellers have been waiting for.

At first glance, being able to export an inventory forecast sounds like a small quality-of-life improvement.

I don't think it is.

For years, Amazon's Inventory Forecast has helped sellers visualize future demand, but the data has been trapped inside an interactive graph. You could look at it, but you couldn't export it into your purchasing models, cash flow forecasts, or inventory planning process.

If Amazon rolls out the download feature as discussed, that finally changes.

But after leaving that session, I found myself thinking about a different question.

Even if sellers can download Amazon's forecast, does it actually tell them everything they need to know?

The answer is no.

Amazon's forecast can estimate how many units you're likely to sell.

It can't tell you what it will take to achieve those sales.

And that's where the real planning begins.

What Is the Amazon Inventory Forecast Tool?

The Amazon Inventory Forecast tool estimates future customer demand for individual products based on Amazon's forecasting models.

Today, sellers can access the forecast inside Seller Central as an interactive graph showing projected weekly unit demand. It's a valuable planning tool, especially for brands managing seasonal products, replenishment cycles, or complex inventory operations.

The challenge has always been accessibility.

While sellers can view the forecast, they can't export the underlying data into spreadsheets or planning systems. That makes it difficult to:

• Compare forecasts over time.  

• Incorporate projections into purchasing and cash flow models.  

• Share data across finance, operations, and supply chain teams.  

• Build long-term inventory planning workflows.  

If Amazon introduces the expected download capability, sellers will finally be able to use the forecast as data—not just as a chart.

Why an Amazon Inventory Forecast Download Matters

Inventory mistakes are expensive.

Run out of inventory, and you don't just lose sales—you lose Buy Box momentum, organic ranking, advertising efficiency, and customer trust.

Order too much inventory, and cash gets tied up while storage costs continue to accumulate.

That's why downloadable forecast data could be especially valuable for:

• Seasonal brands planning around demand spikes.  

• Food and beverage companies managing expiration dates.  

• Supplement brands coordinating replenishment.  

• Sellers using Amazon Warehousing and Distribution (AWD).  

• Businesses managing inventory across multiple fulfillment locations.  

Instead of checking a graph inside Seller Central, sellers will be able to incorporate Amazon's demand projections directly into the planning tools they already use.

That's a meaningful improvement.

Forecasting Isn't Just About Preventing Stockouts

One of the biggest misconceptions about inventory forecasting is that it's only useful when something goes wrong.

In reality, it's just as valuable when everything is going according to plan.

Imagine a coffee brand facing rising commodity prices.

Management may decide to delay its next inventory purchase, hoping costs come down.

Without reliable demand projections, that's largely a judgment call.

With a forecast, the business can estimate how many units—and how much revenue—it is likely to sacrifice by waiting.

Instead of making decisions based on instinct, brands can make them based on measurable trade-offs.

That's a much stronger position to be in.

A Real Example: When Inventory Becomes the Limiting Factor

One Quartile client in the gourmet food category illustrates why forecasting matters.

Their best-selling ASIN had maintained stable sales of roughly 665 units per week through mid-June.

Then inventory became constrained.

Sales dropped to:

Compared to historical demand, the brand lost approximately 2,330 unit sales over a single month.

At an average selling price of $39, that's nearly $91,000 in estimated lost revenue.

Here's what stood out.

Amazon's own Inventory Forecast continued projecting demand of roughly 700–740 units per week through the rest of the year.

Demand hadn’t disappeared. Inventory availability had become the constraint.

That's an important distinction because many brands instinctively blame advertising when sales fall.

In this case, advertising wasn't the problem. Inventory was.

That's exactly the kind of insight a demand forecast should help uncover—before revenue is lost, not after.

Where Amazon's Forecast Ends

Amazon's Inventory Forecast answers one question well:

How many units is a seller likely to sell?

The next questions are often the ones that determine business performance:

• How much advertising investment supports that demand?  

• What happens if advertising budgets increase?  

• What if the business wants to grow beyond Amazon's projected baseline?  

• How should advertising strategy change if inventory becomes constrained?  

• How does a target ACoS affect future sales?  

Amazon doesn't answer those questions.

That's not a criticism of the tool.

It's simply outside its scope.

Demand isn't just measured.

It's influenced by advertising, promotions, pricing, availability, and dozens of business decisions.

Forecasting units without considering those factors only tells part of the story.

Why Advertising and Inventory Planning Should Work Together

Advertising is one of the few growth levers brands can adjust almost immediately.

Budgets can increase. Campaigns can expand. New audiences can be activated. Promotions can accelerate demand.

All of those decisions influence future sales—and by extension, future inventory requirements.

That's why I don't believe inventory planning and advertising planning should happen independently.

They're two sides of the same conversation.

When inventory becomes constrained, reducing advertising investment often makes sense because there's little value in generating demand for products that can't ship.

Once inventory recovers, advertising can scale again to help rebuild sales momentum.

Planning both together creates a much more resilient growth strategy.

Where Quartile Adds Value

Amazon's Inventory Forecast estimates future demand based on Amazon's models.

Quartile builds on that by helping brands forecast the advertising investment required to achieve—or exceed—that demand.

Using historical advertising performance, inventory availability, seasonal trends, efficiency targets, and business growth objectives, Quartile models how different advertising strategies are likely to influence future sales and inventory requirements.

But the technology is only part of the equation.

Every Quartile client works with a dedicated team of Amazon advertising experts who review these forecasts alongside the brand's broader business objectives. Together, they evaluate questions such as:

• Should advertising investment increase to support an upcoming inventory purchase?  

• Is projected inventory sufficient for Prime Day or another major promotional event?  

• Would inventory constraints justify temporarily reducing advertising spend?  

• What level of growth is realistic while maintaining profitability targets?  

Rather than planning advertising and inventory in separate conversations, brands receive strategic guidance that connects both, helping them make more informed decisions before inventory challenges or missed growth opportunities arise.

Looking Ahead

If Amazon launches the downloadable Inventory Forecast feature as discussed at Seller Growth Summit, it will be a meaningful improvement for sellers.

Being able to export forecast data instead of simply viewing it will make purchasing, replenishment, and financial planning significantly easier.

But after leaving that session in New York, my biggest takeaway wasn't that we'd finally be able to download the data.

It was that sellers would finally be able to do more with it.

Forecasting demand is an important first step.

The brands that consistently outperform their competitors are the ones that combine those forecasts with inventory strategy, advertising investment, and business planning to make better decisions before they become urgent.

That's what turns a forecast into a growth plan.
