GST Reconciliation Software: Auto‑Reconcile GSTR‑2B

Description and use

GSTBot automates reconciliation of purchase registers with GSTR‑2B, cutting time from hours to minutes and reducing ITC leakage risk.

Problem

Manual reconciliation of purchase registers against GSTR‑2B is time‑consuming and error‑prone, risking ITC leakage, audits, and penalties.

Outcome

GSTBot reduces reconciliation time from hours to minutes, improves accuracy, and provides real‑time dashboard insights, protecting SMBs from ITC gaps and compliance issues.

Workflow

• Upload invoices (photo, PDF, Excel)
• OCR and data extraction via Tesseract OCR and OpenRouter language models
• Store extracted data in PostgreSQL, cache with Redis
• Pull GSTR‑2B file for the tax period
• Deterministic matching on GSTIN, invoice number, date, amount
• Flag status (Reconciled, Mismatch, Missing, Duplicate)
• Apply Rule 37/42/43 checks and supplier filing status
• Display results in dashboard
• Allow manual adjustments, ignore, re‑run, or manual match via search

Evidence

Accountants spend hours matching each line‑item in the purchase register against the corresponding entry in the GSTR‑2B download.
