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.
Understocking leads to missed sales and disappointed customers.
Overstocking locks up capital and adds to storage costs.
Inaccurate demand projections, thanks to unpredictable consumer behavior and aggressive competitors, can throw everything off.
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.
1. AI-Driven Demand Forecasting
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:
Pull real-time data from multiple sources (Shopify, Amazon, Meta Ads, Google Ads, and more)
Analyze past Prime Day patterns and current trends
Forecast SKU-level demand based on category performance and marketing inputs
Show you which products are gaining traction before they explode in demand.
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.
2. Balancing Stock Levels Across Channels
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:
Sync your inventory system across all platforms
Prioritize stock allocation based on channel performance from previous Prime Days
Use tools or fulfillment partners that offer smart inventory distribution
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.
3. Aligning Ad Spend with Inventory Levels
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:
Increase inventory to meet ad demand: If a product is forecasted to sell well and is a core part of your campaign, scale up your inventory to support your paid media plan.
Reduce ad budget for low-inventory SKUs: If you can’t restock quickly, don’t push that product in your ads. Reallocate the budget to SKUs with higher stock and similar margins.
4. Optimizing Product Listings for Maximum Conversions
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:
Use high-quality images that show the product from multiple angles
Update titles and bullet points with keywords customers are searching for
Highlight Prime Day-specific offers like limited-time pricing or bundled deals
Add A+ Content (on Amazon) or detailed product descriptions (on your DTC site) to boost conversion
Collect fresh reviews in the weeks leading up because social proof drives Prime Day sales
Don’t just focus on price. Visibility and presentation are what bring customers in and get them to click the “Buy Now” button.
5. Running Effective Lightning Deals & Promotions
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:
Only run them on high-volume SKUs where you can afford discounts.
Ensure you have enough inventory to meet the deal demand.
Analyze past promotions to set discount levels that boost conversions without killing profits.
When used wisely, promotions can drive a short-term spike and long-term brand awareness.
6. Leveraging PPC & Sponsored Ads
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:
Sponsored Products: Target high-intent keywords for your top SKUs
Sponsored Brands: Promote bundles or top categories to boost AOV
Sponsored Display: Retarget visitors who’ve shown interest but didn’t buy
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.
7. Enhancing Customer Experience & Retention
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:
Fast, reliable delivery: Use FBA or top-tier 3PLs to ensure on-time fulfillment
Great unboxing and packaging: If it attracts and looks premium, they’ll be back again for more
Responsive support: Reply quickly to inquiries and handle issues with care
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.
8. Strengthening Post-Prime Day Remarketing Strategies
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:
Run retargeting ads on Facebook, Google, and Instagram for 1–2 weeks after Prime Day for those who missed it.
Create email flows for new customers: order confirmation → product tips → follow-up offer.
Use Amazon’s DSP (Demand Side Platform) to re-engage audiences who browsed but didn’t buy.
Stay top of mind. The sale may be over, but your growth doesn’t have to be.
9. Managing Post-Prime Day Inventory Efficiently
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:
Replenish bestsellers quickly to keep the momentum going.
Run clearance deals or bundles on slow-movers to free up storage space.
Use data to plan better for upcoming sales.
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.
10. Analyzing Performance & Preparing for Future Events
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:
Total sales and profit margins
ROAS across ad channels
Conversion rates by SKU
Inventory turnover
New vs. returning customer ratio
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.
