Using an Amazon repricer is not just about automatically changing prices. The real advantage comes from tracking the right seller metrics and understanding how repricing affects your business.
Many sellers turn on automated repricing and assume the work is done. But that’s where the real monitoring should begin. If you track the wrong data or don’t track anything at all, you can lose profit, hurt your Buy Box performance, or get pulled into constant price wars without even realizing it.
To get the best results from repricing, sellers must closely monitor both pricing and account-level metrics. These numbers help you understand whether your repricing strategy is increasing sales, protecting margins, and improving overall seller health.
In this article, we’ll discuss the most important metrics every Amazon seller should monitor while using a repricer.
Metrics Every Amazon Seller Should Track While Repricing
Using a repricer on Amazon can save time and increase sales, but success comes from monitoring the right metrics. Tracking the wrong data or ignoring metrics can result in lost profit, poor account health, or endless price wars. Here are a few metrics that really matter when using a repricer.
1. Buy Box Win Rate
What it is:
Buy Box Win Rate measures how often your product appears in the Buy Box compared to other sellers. The Buy Box is the main section where customers click “Add to Cart” on an Amazon listing. A higher win rate means your product is more visible and likely to sell. This rate depends on pricing, seller performance, inventory availability, and fulfillment method.
Why it matters:
Winning the Buy Box is critical because most Amazon sales happen through it. Even if you have a great product or competitive price, not appearing in the Buy Box means fewer sales. Monitoring this metric helps you see if your repricer is actually improving visibility and competitiveness. If Buy Box wins don’t increase despite lower prices, it indicates issues beyond pricing, like fulfillment or account health.
How to track/improve it:
a. Use tools to monitor Buy Box percentage for each SKU.
b. Ensure pricing is competitive but sustainable.
c. Improve seller performance metrics such as Order Defect Rate (ODR) and shipping speed.
d. Consider Fulfillment by Amazon (FBA) for faster delivery.
With ChannelMAX, sellers can reprice based on Buy Box logic instead of blindly undercutting competitors. This helps you win the Buy Box without affecting margins.

2. Profit Margin (After Amazon Fees)
What it is:
Profit margin is the money you keep after covering all costs, including Amazon referral fees, fulfillment costs, shipping, storage, and advertising. It shows the real profit from every sale, not just revenue.
Why it matters:
Many sellers focus on increasing sales volume, but without monitoring margins, profits can disappear. A repricer may boost sales but silently reduce profit if prices are too low. Protecting margins ensures your business remains financially healthy and sustainable.
How to track/improve it:
a. Calculate profit per SKU after all Amazon fees.
b. Include all costs such as referral fees, FBA or FBM fees, shipping, storage, and advertising expenses.
c. Set a minimum profit margin for each SKU in your repricer to prevent losses.
d. Regularly review your profit trends per product to make sure you are earning sustainably.
3. Sales Velocity
What it is:
Sales velocity measures how quickly your inventory is selling over a given period. It shows how customers are responding to your pricing and whether your products are moving at a healthy pace.
Why it matters:
Stable sales velocity means your repricing is balanced and predictable. Sudden spikes followed by long gaps can mean that your repricing is too aggressive or inconsistent. It can confuse Amazon’s algorithm and harm inventory management. Monitoring this helps prevent stockouts and overstocking.
How to track/improve it:
a. Track sales per day or week for each SKU.
b. Use repricer settings to avoid drastic price drops.
c. Analyze patterns: a slow week may indicate prices are too high.
d. Adjust repricing rules based on historical demand trends.
e. Use repricer reports to identify slow-moving SKUs and apply targeted discounts.
ChannelMAX allows sellers to control price movement based on the selling speed of your inventory, so sales grow smoothly without triggering unnecessary price wars.
4. Inventory Sell-Through Rate
What it is:
Inventory sell-through rate is the percentage of stock sold within a specific period compared to the total inventory available. It helps determine how quickly products leave your warehouse or FBA inventory.
Why it matters:
Knowing your sell-through rate helps prevent overstocking or stockouts. A healthy sell-through rate shows inventory is moving efficiently. A low rate may indicate pricing is too high or demand has dropped. While a high sell-through may indicate underpricing or insufficient inventory planning. Tracking this metric helps manage pricing rules for overstocked or slow-moving SKUs.
How to track/improve it:
a. Monitor sell-through weekly or monthly.
b. Apply discounts to slow-moving stock without harming profit.
c. Slow down repricing on items with low stock.
d. Consider demand patterns before setting repricer rules.

5. Price Position vs Competitors
What it is:
Price position shows how your price compares to other sellers on the same product listing. It helps understand your competitive position without just looking at who is cheapest. It’s not always about being the cheapest, Amazon considers other factors like seller ratings and fulfillment method.
Why it matters:
Being the lowest-priced seller isn’t always necessary to win the Buy Box. Sometimes, slightly higher prices win the Buy Box if your seller metrics, shipping speed, or customer service are stronger. Monitoring price position prevents unnecessary price wars and ensures your pricing strategy is smart, not reactive.
How to track/improve it:
a. Check competitor prices daily or weekly.
b. Set min/max pricing rules to avoid extreme fluctuations.
c. Don’t respond to every small competitor price change.
d. Focus on value-based pricing, considering fulfillment, seller metrics, and customer trust.
ChannelMAX helps sellers stay competitive without automatically dropping to the bottom, reducing price wars and margin loss.
6. Order Defect Rate (ODR)
What it is:
ODR measures order quality issues, including negative feedback, A-to-Z claims, and chargebacks. It reflects overall order quality and customer satisfaction. Amazon expects this to remain below 1%.
Why it matters:
A high ODR indicates operational problems. Aggressive repricing can increase orders quickly, but if your fulfillment can’t keep up, ODR may rise, affecting Buy Box eligibility and account health. Maintaining a low ODR is crucial for Buy Box eligibility and account health.
How to track/improve it:
a. Monitor ODR per SKU and overall account.
b. Align repricing with your fulfillment capacity.
c. Maintain fast shipping, accurate fulfillment, and good customer service.

7. Late Shipment Rate
What it is:
This metric measures the percentage of orders shipped after the expected date. It shows how reliable your delivery process is and whether your fulfillment can handle a huge volume of orders.
Why it matters:
Tracking this metric helps you see if your shipping process keeps up with demand. Late shipments reduce customer trust and can hurt your account health. Even with perfect pricing, slow delivery can prevent Buy Box wins and lower seller ratings.
How to track/improve it:
a. Use FBA or reliable shipping partners.
b. Monitor shipment deadlines daily.
c. Avoid rapid sales spikes that your fulfillment can’t handle.
8. Cancellation Rate
What it is:
Percentage of orders canceled before shipping. This metric reflects how well your inventory and repricing strategy are synced. A high rate may indicate that orders are accepted faster than stock updates or that inventory management isn’t accurate.
Why it matters:
High cancellations usually indicate inventory mismatches or repricing that moves too fast. Amazon tracks cancellations closely, and high rates can impact Buy Box eligibility, ODR, and account health.
How to track/improve it:
a. Sync inventory accurately with your repricer.
b. Avoid selling more than your stock.
c. Monitor trends and adjust your pricing rules to match stock availability.

9. Revenue vs Profit Trend
What it is:
Compares revenue growth to profit growth over time. This metric shows whether your sales are actually generating real profit for your business or just increasing turnover without improving profitability. Tracking it helps identify whether repricing is sustainable in the long run.
Why it matters:
Revenue growth without profit growth indicates low-margin repricing. Tracking both ensures your strategy drives sustainable business growth, not just short-term sales.
How to track/improve it:
a. Monitor monthly revenue and profit per SKU.
b. Adjust minimum prices to protect profit.
c. Review repricer rules regularly to avoid margin loss.
10. Price Change Frequency
What it is:
Measures how often your repricer changes prices. It reflects how stable or reactive your pricing strategy is.
Why it matters:
Constant price changes in a short time can confuse buyers, trigger price wars, and signal to Amazon that your listing is unstable. Stable, strategic pricing is more effective than frequent price changes.
How to track/improve it:
a. Limit updates to meaningful price adjustments.
b. Avoid reacting to every small competitor move.
c. Focus on strategic repricing that balances competitiveness and stability.
Tracking these metrics allows Amazon sellers to reprice smarter, protect profits, maintain account health, and win the Buy Box consistently. Proper monitoring ensures your repricing strategy is data-driven, sustainable, and profitable.
To sum up, repricing on Amazon is much more than just automatically adjusting prices. By closely monitoring Buy Box win rate, profit margins, sales velocity, inventory sell-through, price positioning, and key account health indicators like ODR, late shipment, and cancellation rates, sellers can maximize sales, protect profits, and maintain a healthy account.
Tracking them consistently helps you to avoid price wars, optimize inventory, and make your repricing strategy sustainable. Combined with smart pricing rules, these metrics ensure that your repricing efforts not only increase sales but also build long-term growth and profitability for your Amazon business.
