What we built

Bedrock-deployed RAG copilot over Tally, Zoho Books, and bank statements. Replaces 60% of manual reconciliation work and accelerates monthly close from 9 days to 2.

Costtrail engaged on a partnership basis across 2 pillars — AI / GenAI Engineering, Product Engineering. Delivered in 2-week sprints with weekly demos, eval-gated deploys, and quality checks at every milestone. Code, infrastructure, and operations were handed back to the client team at close, with optional 24/7 SRE support after launch.
