GSTBot’s AI-Driven GSTR‑2B Matching Feature

Description and use

GSTBot automates e‑way bill creation for Indian SMBs using OCR and AI validation, ensuring state‑specific compliance and reducing processing time from hours to seconds.

Problem

For Indian SMBs, generating e‑way bills for every high‑value shipment is a regulatory requirement that can quickly become a bottleneck. The manual process—entering details into the GST portal, validating them against the purchase register, and ensuring compliance with state‑specific limits—consumes hours of an accountant’s time and introduces the risk of data entry errors. When invoices are received as PDFs or images, the need to extract vendor and transaction details adds another layer of complexity.

Outcome

GSTBot reduces e‑way bill creation from hours to seconds, improves accuracy through OCR and AI validation, enforces state‑specific compliance, and integrates with ITC workflows.

Workflow

• Upload invoice (photo, PDF, or Excel) via React/Vite interface
• OCR with Tesseract extracts vendor GSTIN, invoice number, total amount, tax rate, HSN code into JSON
• AI model on OpenRouter validates extracted data against GSTR‑2B and PostgreSQL purchase ledger
• State‑aware composition checks flag limits and adjust bill
• AI composes Part A and Part B of the e‑way bill
• User reviews extracted fields and can tweak values
• Single click generates bill, highlights restrictions, offers download
• User can submit via built‑in API button or copy JSON to GST portal

GSTBot’s /eway‑bill‑generator feature automates the entire e‑way bill creation workflow. Once an invoice is uploaded (photo, PDF, or Excel), the system uses Tesseract OCR to read the document and extracts key fields such as vendor GSTIN, invoice number, total amount, tax rate, and HSN code.

The extracted data is then fed into an AI model hosted on OpenRouter, which verifies the information against the user’s stored purchase register and GSTR‑2B data.

The feature also incorporates state‑aware composition checks, ensuring that the generated e‑way bill complies with local limits.
