Like every year, Amazon Prime Day 2025 is expected to drop in mid-July. And just like clockwork, it’ll be one of the biggest sales events of the year. In 2023, Prime Day raked in over $12.9 billion in sales globally. Millions of shoppers wait for it. Brands prepare for weeks and some for months.
But here’s the thing, even with all that excitement, many businesses still lose money.
Why? Two of the major reasons are poor demand forecasting and inventory mismanagement.
We’ve seen it happen time and again.
The result is lost revenue and messy operations during what should be a peak-profit period.
To help you avoid those mistakes, we’ve listed 10 things eCommerce sellers must do to scale smartly and profitably this Prime Day.
Let’s dive in.
As we mentioned, one of the biggest mistakes on Prime Day is guessing demand. In 2025, there’s no excuse for relying on gut feel. AI-driven demand forecasting uses historical sales, seasonality trends, market signals, and even competitor pricing to help you predict what’s going to sell and how much of it.
When done right, it allows you to plan inventory smartly, avoid stockouts, and reduce overstocking. This is where AI-powered eCommerce analytics platforms like Graas come into play.
Here’s how it helps:
Let’s say your store sells skincare products. If AI forecasts a 40% spike in Vitamin C serums and only 10% for moisturizers, you’ll know exactly what to stock up on and how much marketing fuel to put behind each.
Without this insight, you're just guessing. And during Prime Day, guessing can be expensive.
Once you know what customers are likely to buy, the next step is ensuring that inventory is available in the right place. It’s necessary because stock sitting in one warehouse while demand peaks on another sales channel doesn’t help anyone.
You need to balance stock levels across all sales channels while making Amazon the priority. Because demand will be quite high here compared to other channels.
Here’s how to do it once demand is forecasted:
For example, if 70% of your traffic during Prime Day comes from Amazon but 50% of your stock is sitting in a warehouse dedicated to DTC sales, you’re setting yourself up to lose. Plan smart and move inventory ahead of time.
Spending big on ads for products you don’t have enough inventory for is a silent killer. Yes, you might have a strong demand. Yes, your ROAS might look great. But if you can’t fulfill the orders? That’s wasted ad spend and unhappy customers.
To avoid that, align your ad strategy with your inventory availability.
You can approach it in two ways:
During Prime Day, where your product appears matters as much as what you’re offering. Even if you're offering a killer deal, it won’t sell if customers can’t find it or if your listing doesn’t convert.
Your goal is to make it ridiculously easy for customers to click and buy.
Here’s how to optimize listings before Prime Day:
Don’t just focus on price. Visibility and presentation are what bring customers in and get them to click the “Buy Now” button.
Lightning Deals can be a powerful tool to drive visibility and sales during Prime Day. They create urgency, tap into FOMO, and push products up in search rankings.
But there’s a catch. Slashing prices without a strategy can hurt your margins.
To make the most of Lightning Deals:
When used wisely, promotions can drive a short-term spike and long-term brand awareness.
Prime Day is pay-to-play, especially on Amazon. With so many brands competing, organic rankings often aren’t enough. That’s why your PPC game needs to be strong too.
Start by tightening your organic listings. Make sure your keywords, titles, and images are optimized. Then, layer on paid ads to boost visibility.
Here’s what to do with Amazon Ads:
Bonus: Use Google Ads to drive traffic to your Amazon listing. A well-placed search or shopping ad with “Prime Day Deal” in the copy can capture outside intent traffic and push it to your high-converting Amazon product page.
The only reason every brand is ready to leave a chunk of their profit on Prime Day is because they know it's not just about revenue. It’s about acquiring new customers you can retain. Retained customers are 5x more valuable over time. So give them a reason to come back.
They’ll come back when they have a good experience with your brand. Improve experience with:
Follow up with a thank-you email, ask for reviews, and offer a small incentive to return. That’s how you turn a one-time shopper into a loyal customer.
Prime Day might end in 48 hours, but the opportunity doesn’t. Use remarketing to bring back window shoppers and one-time buyers.
Here’s what you can do to bring more customers:
Stay top of mind. The sale may be over, but your growth doesn’t have to be.
Once the Prime Day madness is over, it’s time to take a hard look at your inventory. Some SKUs might be wiped out. Others may be sitting unsold. Both situations need attention.
Start by reviewing your sell-through rate to understand which products performed well and which didn’t. Then, adjust your inventory strategy accordingly.
Steps to take post-Prime Day:
And don’t forget: excess inventory can eat into profits through storage fees, especially if you’re using FBA. Act fast to avoid long-term costs.
Every Prime Day is a chance to learn. You need to dig into the numbers and understand what worked and what didn’t.
Start with these metrics:
Use this analysis to refine your strategy for Q3 and Q4 events. Which promotions worked best? Which ad creatives drove the most clicks? Which products had the highest conversion but ran out of stock?
Pro tip: Create a Prime Day post-mortem report. Share it with your team, document key insights, and build a playbook for future sales.
Without data, you're basically shooting at a target you can't see. Your guesses might completely miss the mark. The result? Negative profit, wasted resources, and missed opportunities.
