Product
From the site to the bank statement.
A bill on WhatsApp, a muster in a notebook, a payment in net banking and a return on the GST portal become linked records in one system.
01 / Capture
02 / Ledgers
Approvals and supplier ledgers
Bills move through an approval queue, then into a running ledger for each supplier, showing billed, paid and balance per supplier and per project. Advances paid to suppliers are tracked as their own balance.
03 / Labour
Attendance to weekly wages
Labour attendance is marked daily on a phone. Weekly payments to labour contractors are generated from that attendance, and each payment can carry the bank's UTR reference.
04 / GST
GST reconciliation
Purchase bills are compared with GSTR-2B and grouped into bills not yet in 2B, bills in 2B but not yet in the books, and credit close to its claim deadline.
All screens are from the live system. Supplier and worker names are replaced with labels. Every rupee amount is multiplied by one fixed factor, so figures still add up but are not the real values.
AI
AI for document-heavy work
Government construction runs on long tenders, CPWD specifications and handwritten bills. Rachisu Track uses language models to read them, and staff review the output before anything is booked.
Tender extraction
Claude reads a CPWD tender document and extracts structured project data. During extraction it can search the CPWD knowledge base.
Claude Opus · tool useCPWD knowledge base
Works manuals, general specifications and schedules of rates are split into searchable sections. Staff search them in plain language, or ask a question and get an answer drawn from those documents.
Semantic searchBill reading
A photographed invoice is read into structured fields for the office to review before the expense is booked.
