From 185,000 manual stamp entries

The Problem

JTI Ukraine is required to submit excise stamp data to Ukrainian tax authorities annually to claim tax refunds on tobacco products. Each of the ~185,000 stamps requires three fields to be manually entered: Date, Number, and Series.

  • 555,000 manual data points entered into Excel, one stamp at a time.
  • 24+ week turnaround from stamp collection to tax refund approval.
  • Error-prone process with no deduplication — duplicate stamps went undetected.

The solution

One orchestrator agent. Zero manual touchpoints.

Nanonets replaced the manual loop with one autonomous agent. The agent orchestrates five sub-agents which each own one step of the pipeline — monitoring Drive, splitting stamps, detecting duplicates, extracting fields, and exporting structured data — with no human in the loop.
