The Starting Point

"I was frustrated," Thomas recounts. "We had good products, competitive prices, but the Buy Box usually belonged to the others."

The numbers before the optimisation:

The main problem: Thomas adjusted prices only once a week. In the meantime, the competition had long since reacted.

The Analysis

Together, we analysed Thomas' situation:

Problem 1: Price adjustments too slow

While Thomas adjusted prices once a week, the competition reacted within minutes. He often lost the Buy Box again shortly after winning it.

Problem 2: No competitor differentiation

Thomas treated all competitors the same. But an FBM seller with an 87% rating is no real competitor for an FBA seller.

Problem 3: No minimum prices

To win the Buy Box, Thomas sometimes dropped below the profitability threshold. More sales, less profit.

The New Strategy

Weeks 1-2: Setup

Setting up Sellercore with automated repricing. Defining minimum prices for all 2,000+ products based on real costs.

Weeks 3-4: Competitor segmentation

Configuring the competitor filters: ignore FBM sellers with a <95% rating. Compete only against relevant FBA sellers.

Weeks 5-8: Optimisation

Fine-tuning the repricing rules. Different strategies for different product categories. More aggressive on fast movers, more conservative on niche products.

Weeks 9-12: Scaling

Extending the successful strategies across the entire portfolio. Automated alerts for margin problems.

The Results

After 12 weeks, Thomas' dashboard looked completely different:

Before

  • Buy Box Rate: 38%
  • Margin: 18%
  • Revenue: 85.000€

After

  • Buy Box Rate: 85% (+47%)
  • Margin: 21% (+3%)
  • Revenue: 138.000€ (+62%)
The remarkable part: The margin rose as well, even though more Buy Box was won. The reason: intelligent repricing instead of blindly undercutting.

The Key Learnings

Thomas sums up his findings:

  1. "Speed beats price" - Whoever reacts faster often wins even with a higher price
  2. "Not all competitors are equal" - Apply filters to relevant competitors
  3. "Minimum prices are sacred" - Better to lose the Buy Box than to burn money
  4. "Data beats gut feeling" - Make decisions based on analytics

Conclusion

Thomas' story shows: the Buy Box is no mystery. With the right strategy and the right tools, any seller can improve their rate significantly.

"The biggest mistake was thinking I could do this manually," Thomas says today. "In a market that changes by the minute, you need automation."
