The Challenge

The Buy Box decides
who gets the sale

Amazon's November 2025 algorithm update fundamentally changed how the Featured Offer is awarded. Fulfillment method is no longer king — delivery speed, pricing intelligence, and account health now share equal weight. Most tools haven't caught up.

Fulfillment-Agnostic

FBA no longer guarantees the Buy Box. FBM sellers with fast delivery now compete on equal footing. SFP has the highest potential.

Algorithm Change

2-3% Tolerance Band

You don't need the lowest price. Amazon evaluates landed price within a tolerance band — making smart repricing more important than aggressive repricing.

Opportunity

Delivery Speed: 25-30%

Delivery speed now accounts for 25-30% of algorithm weight, up from ~15%. This creates new openings for sellers with regional fulfillment.

New Weight
Market Landscape

Five tools dominate
Amazon repricing today

Every major repricing tool has significant gaps — in speed, intelligence, or pricing fairness.

Tool Price Speed Best Feature Biggest Weakness
Aura $27-397/mo 2 min Low margin erosion (2.1%) AI slot caps, FBM bugs
BQool $25-300/mo 8.5 min $25/mo entry, 8 AI strategies Price tanking (#1 complaint)
Repricer.com $199-599/mo 90 sec Net Margin auto-fee floors Overpriced, reliability issues
Seller Snap $250-800/mo 25 min+ Game theory (low competition) Speed, no sales data in AI
Feedvisor $100-1500+/mo Slow ProductSphere (private label) Enterprise pricing, fees eat margin
Speed Benchmark

The repricing speed gap

Every minute of latency is revenue lost. Current best-in-class is 90 seconds. We're targeting sub-30.

Demand-aware core: order velocity drives every pricing decision
"Slow repricing quietly killed volume even though margins looked fine."
Sub-30-second latency from SQS notification to price update

FBM-first: three distinct strategies for FBA, FBM, and SFP
Our Approach

Six principles that
fix what's broken

Each principle is traced directly to competitor evidence and seller pain points.

01

Sub-30s Repricing

SQS notification to SP-API price update in under 30 seconds. No slot limits on speed. 3x faster than current best.

vs. Repricer.com 90s, Seller Snap 25min
02

Zero Artificial Caps

Every listing gets AI repricing. No tier-gated AI slots, no SKU bolt-ons, no revenue caps. Scale pricing by usage, not features.

vs. Aura 50-10K AI slots, BQool caps
03

Anti-Tanking by Design

Optimize for the highest Buy Box-winning price, never the lowest. Circuit breaker pauses if price drops >5%/hour.

vs. BQool tanking, 4.7% industry erosion
04

Auto Fee-Aware Floors

Auto-pull Amazon referral, FBA, and closing fees via SP-API. Seller inputs COGS once — system calculates floor automatically.

vs. Repricer.com Premium-only ($399+)
05

FBM-First Intelligence

Three distinct strategies for FBA, FBM, and SFP with different tolerance bands, fee structures, and delivery speed factoring.

vs. Aura FBM bugs, BQool 4-8h lag
06

Demand-Aware AI

Order velocity feeds directly into pricing. High demand accepts lower margin. Low demand protects margin. Stockout risk raises price.

vs. Seller Snap "no sales data in AI"
