How To Never Go Out of Stock On Amazon

If you’re running out of stock on Amazon, you’re literally handing your competition free money.

As an Amazon Sales Expert and the CEO of EHP Consulting Group, I’ve worked with hundreds of Amazon sellers across Florida and beyond. One of the biggest mistakes I see? Sellers crushing it… only to have everything tank when they run out of inventory.

Let’s talk about how to never go out of stock again—and how to keep your momentum, protect your rank, and make more money on Amazon consistently.

Why Staying In Stock Is Critical for Amazon Sellers

When you sell out on Amazon, it’s not just a sales pause—it’s a momentum killer. You’ll lose rank, your PPC campaigns will underperform, and Amazon’s algorithm might favor competitors instead.

Your product’s performance history and velocity are tied to your inventory health. Let it slip, and you’ll spend weeks (or months) clawing your way back up.

That’s why smart Amazon experts prioritize inventory forecasting and restocking strategy—especially if you’re working with long lead times or relying on overseas manufacturers.

Step 1: Monitor Inventory Weekly Like a Pro

We help our clients at EHP Consulting Group set up custom reports to monitor stock levels every single week—not monthly, not quarterly. Why? Because demand changes fast.

Here’s what to track:

Sales from the last 3 and 30 days
Current FBA inventory
Reserved units
Sell-through rate
Lead time (manufacturer + shipping + Amazon check-in)
Inventory days remaining
Quantity to reorder

Pro Tip: Aim for at least 120 days’ worth of inventory at Amazon, factoring in delays from suppliers, shipping, and Amazon check-in (which can sometimes take 30–60 days!).

❗ Running low? Panic mode starts when you dip below 21 days of inventory.

Don’t want to build spreadsheets? We’ve got you. Reach out to our team of Amazon consultants and we’ll set up a custom inventory report for you.

Step 2: Use Tools (If You Don’t Have a Team)

No time to build spreadsheets or hire help? Use inventory forecasting tools like:

🔧 Jungle Scout Inventory Manager – Simple to use, great restock suggestions
🚀 Helium 10 Inventory Protector – Free trial available and powerful inventory alerts

But even Amazon’s built-in inventory tools can help. Go to:

Seller Central > Inventory Planning > Restock Inventory

Warning: Amazon’s restock recommendations are not always accurate. They’re often 1–3 weeks behind real-time sales spikes. That’s why we recommend doing the math manually—or letting a team like EHP Consulting Group handle it.

Step 3: Know Your Lead Time (And Add a Buffer)

Here’s a breakdown of what to consider:

Manufacturing Time: How long does it take to produce? 15–30 days? 60?
Shipping Time: Are you using ocean freight or air?
Amazon Check-In: Sometimes it takes 7 days. Other times? 30+.

Add it up. If your lead time is 45 days, and it takes Amazon 15 more to check it in, you’re looking at a 60-day total. Always plan for worst-case scenarios.

At EHP Consulting Group, we coach clients to never operate below a 120-day inventory buffer. That’s how we prevent surprise stockouts—even during Prime Day, Black Friday, or seasonal surges.

Stop Relying on Amazon’s Numbers Alone

Amazon might tell you to send 19 units when you really need 150. Their calculations can lag behind your actual sales momentum.

Take control with weekly data reviews. Need help building your inventory system or want to outsource all of this completely? Our Florida Amazon Consultant team can take over for you—from inventory management to full-service Amazon account handling.
