From file upload to a complete ITC summary for your GSTR-3B in four easy steps. All processing happens locally in your browser — your data never leaves your device.
Open GSTSyncPro in Chrome and drag & drop (or click to browse) your four data files: GSTR-2B Purchase data, Books Purchase register, GSTR-2B CN/DN data, and Books CN/DN register. Supported formats: Excel (.xlsx, .xls) and CSV.
Click "Reconcile" and GSTSyncPro automatically runs a 3-pass purchase matching algorithm (Exact → Fuzzy → Amount-based) and a 6-pass CN/DN matching algorithm (Cross-type + Same-type). Each pass catches records the previous pass missed.
Review each record in the results table. Use per-record actions — Accept matched pairs, Unmatch incorrect pairs, manually Pair records, Force Pair with overrides, or mark as Not Matched. Bulk select-all and GSTIN-filter make large datasets manageable.
When done, export your reconciliation as a formatted Excel file for filing, a JSON file for ERP integration, or use the Copy ITC Summary button to paste the net claimable ITC figure directly into your GSTR-3B workflow.
All file parsing, matching, and ITC calculation happens entirely inside your Browser. Only license validation communicates with our server — no GSTIN, invoice, or financial data is ever transmitted.
