Distribution Leak Tracing & Test Buy Tracker

A specialized tool for managing test buy operations to trace which distributors leak inventory to Amazon resellers. Users record lot numbers, batch codes, and purchase details from test buys, then the tool attributes leaks to specific distributors and generates violation reports for supply agreement enforcement.

Why this matters

You suspect certain distributors are leaking your products to Amazon resellers but you cannot prove it. You have been told to do test buys and check lot numbers, but you are tracking this in spreadsheets that are disorganized and incomplete. When you find a reseller on your ASIN, you have no systematic way to trace which distributor sold them the inventory. Without this evidence, you cannot enforce your distribution agreement or cut off the leaking distributor. You need a structured system to record test buy lot numbers, match them to distributor shipment records, and build a provable case for supply agreement violations.

  • · Built for Brand owners and manufacturers with multiple wholesale distributors who need to trace and prove which distributor's inventory is being resold on Amazon.
  • · Most likely monetization: SaaS subscription with tiered pricing based on number of distributors and SKUs tracked.

MVP Scope · 1–2 weeks

Week 1
  • Design database schema for test buy records including seller identity, purchase date, lot number, batch code, and product SKU
  • Build distributor shipment log where users record which lot numbers went to which distributor and when
  • Create matching algorithm that compares test buy lot numbers against distributor shipment records to identify leak source
  • Implement test buy entry form with guided workflow for recording all required data fields
  • Set up user authentication and distributor management screen for adding distributor profiles
Week 2
  • Build leak attribution dashboard showing probability scores for each distributor based on matched lot numbers
  • Create violation report generator producing PDF evidence documents linking distributor to specific reseller listings
  • Add timeline view showing historical leak incidents per distributor with dates and affected ASINs
  • Implement distributor compliance scoring and alerting when new leaks are attributed
  • Build onboarding flow with CSV import for existing distributor shipment records and lot number databases
MVP Features: Test buy workflow manager recording purchase date, seller identity, lot number, and batch code per test order · Distributor attribution engine matching lot numbers to distributor shipment records · Leak probability scoring showing which distributors are most likely sources of Amazon reseller inventory · Distribution agreement violation report generator with evidence timeline · Distributor management dashboard tracking compliance status and violation history

Differentiation

Existing solutions
Amazon Transparency ProgramAmazon Project ZeroAmazon Brand Registry
Our angle
No purpose-built tool exists for manufacturers to systematically monitor ASIN seller changes, trace distribution leaks through lot/batch tracking, and generate enforcement evidence trails in one integrated platform

Why This Might Fail

Self-rebuttal — the most important trust signal

  1. 1Many brands do not maintain lot number-to-distributor shipment records, meaning the matching engine has no data to work with without significant manual data entry during onboarding
  2. 2Products without lot numbers or batch codes — which includes many commodity and low-cost manufactured goods — cannot be traced through this method at all, limiting the addressable market
  3. 3Brands may find that manual tracking in spreadsheets, while painful, is sufficient for their 2-3 distributor setup, reducing willingness to pay for a dedicated tool

Evidence Summary

How AI synthesized this insight — no verbatim quotes

Approximately 4 commenters specifically mention test buy operations and lot number tracking as the key method for tracing distribution leaks. One commenter provides a detailed explanation of how evidence gathering works — test buys with lot numbers and dated seller logs — and notes this is where most brands stall. The manual nature of this process and lack of any dedicated tool for managing it represents a clear product gap.
