If you’re selling on Amazon, there’s one goal that matters more than almost anything else: winning the Buy Box. This coveted feature is the key to unlocking serious sales momentum on the platform.
Here’s why it matters: approximately 82% of all Amazon sales happen through the Buy Box. That small « Add to Cart » and « Buy Now » button section isn’t just convenient for shoppers—it’s essential for sellers who want to compete effectively.
This guide is designed specifically for new Amazon sellers, side hustlers, and ecommerce beginners who want to understand exactly what it takes to win the Buy Box. Whether you’re launching your first product or struggling to gain traction with your existing listings, this actionable checklist will show you the path forward.
At Repricer.com, we’ve helped thousands of Amazon sellers win and maintain the Buy Box through intelligent automated repricing. In this guide, we’re sharing the exact strategies our most successful users follow to dominate their product categories.
What Makes You Eligible for the Buy Box?
Before diving into the steps, it’s important to understand that not every seller is eligible for the Buy Box. Amazon has specific requirements that act as gatekeepers.
Professional Selling Plan Required
First and foremost, you need a Professional Seller Account. Individual selling plans simply aren’t eligible for Buy Box consideration, regardless of how competitive your pricing is or how fast you ship. The Professional plan costs $39.99 per month but unlocks critical features including Buy Box eligibility, bulk listing tools, and advanced selling reports.
Key Performance Metrics Amazon Evaluates
Amazon closely monitors several performance indicators when deciding who gets the Buy Box:
- Order Defect Rate (ODR): Should be below 1%
- Late Shipment Rate: Keep it under 4%
- Pre-Fulfillment Cancel Rate: Maintain below 2.5%
- Customer Response Time: Reply within 24 hours
- Valid Tracking Rate: Provide tracking on all shipments
These metrics directly impact your account health and Buy Box eligibility. According to Amazon’s performance targets, maintaining excellent ratings across these areas is non-negotiable.
Fulfillment Method and Pricing Competitiveness
Your fulfillment choice significantly impacts your Buy Box chances. Fulfillment by Amazon (FBA) sellers typically have a major advantage because they offer Prime shipping, which Amazon prioritizes. Seller Fulfilled Prime (SFP) also works, but requires meeting strict performance standards.
Price competitiveness matters, but being the absolute cheapest isn’t always necessary. Amazon’s algorithm considers the total landed cost (item price + shipping), delivery speed, and seller reliability when making Buy Box decisions.
Step-by-Step Buy Box Checklist
Ready to optimize your account for Buy Box success? Follow this comprehensive checklist:
✅ Step 1: Open a Professional Seller Account
If you’re still on an Individual plan, upgrade immediately. Navigate to your Seller Central account settings and switch to Professional. This $39.99 monthly investment is essential—there’s simply no way around it for Buy Box eligibility.
✅ Step 2: Choose FBA or Seller Fulfilled Prime Fulfillment
Amazon strongly favors sellers who can offer Prime shipping. Your best options are:
Fulfillment by Amazon (FBA): Send your inventory to Amazon’s warehouses, and they handle storage, packing, shipping, and customer service. This is the most straightforward path to the Buy Box for most sellers.
Seller Fulfilled Prime (SFP): Ship from your own warehouse while maintaining Prime eligibility. This requires meeting Amazon’s strict delivery and performance requirements but gives you more control over inventory.
If you’re using Fulfillment by Merchant (FBM), you’ll face an uphill battle unless you can consistently offer extremely competitive pricing and fast shipping. Learn more about the differences in our guide on Amazon FBA vs FBM repricing strategies.
✅ Step 3: Set Competitive Pricing (Item + Shipping)
Price is crucial, but it’s not just about your item cost. Amazon evaluates the total landed cost for customers. If you’re charging $20 with $5 shipping while a competitor charges $24 with free shipping, you’re both at $25 total—but the free shipping option may be more attractive.
This is where automated repricing becomes a game-changer. Manually checking and adjusting prices multiple times per day is exhausting and impractical, especially as you scale to dozens or hundreds of products.
Repricer.com’s intelligent repricing software monitors your competition 24/7 and automatically adjusts your prices within your predefined rules to keep you competitive for the Buy Box. Our customers report an average Buy Box win rate increase of 30-50% within the first month of using automated repricing.
Unlike basic repricers that simply race to the bottom, Repricer.com uses smart algorithms that factor in:
- Your minimum and maximum price boundaries
- Competitor seller ratings and fulfillment methods
- Time of day and demand patterns
- Your profit margins and business rules
This means you stay competitive without sacrificing profitability—a critical balance for long-term success.
✅ Step 4: Monitor Performance Metrics
Keep a close eye on your Account Health dashboard in Seller Central. Check it at least weekly, if not daily when starting out. Focus on:
- Responding to customer messages within 24 hours
- Shipping orders on time (every single time)
- Minimizing returns and negative feedback
- Resolving any A-to-Z claims immediately
Strong performance builds trust with Amazon’s algorithm and increases your Buy Box win rate. In fact, better seller feedback on Amazon directly correlates with improved Buy Box eligibility.
✅ Step 5: Maintain Strong Inventory Levels
Nothing kills Buy Box eligibility faster than running out of stock. Stockouts signal unreliability to Amazon and can take weeks to recover from, even after you restock.
Set up low inventory alerts in Seller Central and consider using inventory management software that can predict when you’ll need to reorder based on your sales velocity. For FBA sellers, remember to account for shipment creation and receiving time when planning inventory replenishments. Check out our guide on improving Amazon FBA inventory management for detailed strategies.
✅ Step 6: Optimize Shipping Speed
If you’re fulfilling orders yourself (FBM), shipping speed becomes even more critical. Amazon evaluates:
- Your promised delivery time
- Your actual delivery performance
- Whether you offer expedited options
Fast, reliable shipping can partially offset the Prime advantage that FBA sellers enjoy. Consider partnering with regional carriers or using Amazon’s Buy Shipping services to improve delivery speeds.
✅ Step 7: Check Buy Box Ownership % in Seller Central
Amazon provides data on your Buy Box percentage in the Business Reports section of Seller Central. Navigate to Reports > Business Reports > Detail Page Sales and Traffic by Child Item to see your Buy Box percentage over time.
Track this metric weekly and correlate changes with your pricing adjustments, inventory levels, and performance metrics. This data helps you understand what’s working and what needs improvement.
Pro Tip: Repricer.com users can track their Buy Box percentage directly within our dashboard, making it easier to see the correlation between repricing strategies and Buy Box wins without jumping between multiple platforms.
Extra Tips to Win the Buy Box Faster
Want to accelerate your path to Buy Box dominance? Try these proven strategies that our most successful customers use:
Automate Your Repricing Strategy: Manual price checking simply can’t compete with automated solutions that respond to market changes in real-time. While you’re sleeping or working on other aspects of your business, competitors are adjusting their prices. Repricer.com ensures you never miss a Buy Box opportunity due to outdated pricing, with repricing intervals as fast as every 2 minutes on certain plans. Our velocity repricing rules help you respond intelligently to market changes.
Add the Prime Badge via FBA: If you haven’t already, FBA is your fastest route to the Prime badge. Prime-eligible products win the Buy Box significantly more often than non-Prime offers, with some estimates suggesting a 3-5x advantage. Combined with smart repricing, Prime eligibility creates a powerful competitive advantage. Learn about the pros and cons of Amazon FBA to make an informed decision.
Focus on High-Conversion Listings: Win the Buy Box more consistently by creating compelling product listings with high-quality images, detailed descriptions, and strong reviews. Better conversion rates signal product quality to Amazon and help maintain Buy Box eligibility even when your price isn’t the absolute lowest.
Respond to Customer Messages Fast: Set up mobile notifications for customer messages and aim to respond within an hour during business hours. Quick, helpful responses improve your customer service metrics and demonstrate reliability to Amazon’s algorithm.
Use Strategic Repricing Rules: Not all pricing strategies are equal. Set minimum prices to protect your margins, create time-based rules for peak shopping hours, and establish competitor-specific rules. For example, you might be willing to match certain high-quality sellers but maintain a premium over sellers with lower feedback scores.
What to Avoid
Just as important as knowing what to do is understanding what not to do:
Long Shipping Times: If you’re using FBM and promising 7-10 day delivery, you’re at a severe disadvantage. Shoppers expect fast shipping, and Amazon’s algorithm knows it. If you can’t offer 2-3 day delivery, strongly consider FBA.
High Prices Without Prime: Being expensive and non-Prime is the worst combination. If your prices are above average, you absolutely need the Prime badge to remain competitive.
Ignoring Performance Metrics: Some sellers only check their metrics when something goes wrong. Don’t wait for a problem—monitor proactively and address issues before they impact your Buy Box eligibility.
Racing to the Bottom on Price: While competitive pricing matters, constantly undercutting competitors by large margins destroys your profit margins. Smart repricing means being competitive enough to win the Buy Box while maintaining healthy margins—exactly what Repricer.com is designed to optimize. Avoid these common Amazon Buy Box mistakes that cost sellers thousands in lost revenue.
How to Monitor Your Buy Box Status
Keeping tabs on your Buy Box performance is essential for long-term success. Here’s how to track it effectively:
In Seller Central
Navigate to Seller Central > Reports > Business Reports > Detail Page Sales and Traffic by Child Item. This report shows your Buy Box percentage for each ASIN, helping you identify which products need attention.
Look for patterns: Are certain products consistently losing the Buy Box? Are there specific times when you lose it? This data guides your optimization efforts.

Frequently Asked Questions
How long does it take to win the Buy Box?
New sellers can win the Buy Box within their first few weeks if they meet all eligibility requirements. However, it typically takes 30-90 days to establish consistent Buy Box ownership as you build performance history and seller metrics. Using FBA and competitive pricing accelerates the timeline significantly. Our Repricer.com customers who implement automated repricing from day one often see their first Buy Box wins 40% faster than those who manually adjust prices.
Can new sellers win the Buy Box?
Absolutely! New sellers with Professional accounts, FBA fulfillment, competitive pricing, and strong initial performance metrics can win the Buy Box even against established sellers. Amazon’s algorithm doesn’t inherently favor older accounts—it prioritizes sellers who meet customer expectations best. Smart repricing helps level the playing field by ensuring you’re always competitively positioned. Read our guide on how to win the Amazon Buy Box for detailed strategies.
Do I need to be the cheapest to get the Buy Box?
No, you don’t need the lowest price. Amazon’s algorithm considers total value, including shipping speed, seller reliability, Prime eligibility, and customer service. A seller with slightly higher prices but FBA shipping and excellent metrics often wins over the cheapest option with slow shipping. This is why strategic repricing—not just being the cheapest—is so important. Learn if you can win the Amazon Buy Box without lowering your price.
Is FBA required for the Buy Box?
While FBA isn’t technically required, it provides significant advantages. Seller Fulfilled Prime is an alternative, but requires meeting strict performance standards. FBM sellers can win the Buy Box, but typically need considerably lower prices and exceptional shipping speeds to compete. Combining FBA with automated repricing creates the strongest competitive position. Check out our Amazon FBA program 2025 guide for the latest updates.
How do I check if I’m in the Buy Box?
Visit your product listing while logged out of your seller account (use an incognito window). The seller name shown in the Buy Box indicates who currently owns it. For percentage data, check Seller Central > Business Reports > Detail Page Sales and Traffic by Child Item to see your Buy Box percentage over time. Repricer.com users can also view this data directly in their repricing dashboard for easier tracking across all products. Understanding what the Amazon Buy Box is helps you monitor it more effectively.
