Token Saving in SME Financial Statement Automation

AI Study Case

100 SME Bank Statement Sets → Financial Statements

100 SMEs upload 100 different sets of bank statements. The goal is to generate accurate financial statements for all SMEs.

Generated Reports

The problem is not whether AI can do the job.
The real question is how the system should be designed.

Approach 1

AI Agent Processes 100 Reports One by One

The AI agent reads, understands, classifies, calculates, validates and generates each report individually — repeated 100 times.

GPU Energy

~55 kWh

CO₂ Emissions

~24 kg

Context Reload

100%

Key problems: Full reasoning repeated 100× • 50–100k tokens reloaded every time • No knowledge reuse

Approach 2

Detached System + Smart Routing

AI is used once to build a reusable detached system. Bank statements are segmented and intelligently routed with minimal context.

“The smartest AI system is not the one that uses the most tokens.
It is the one that knows when not to use them.”
