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 upload your data files: GSTR-2B or IMS Purchase data, Books Purchase register, GSTR-2B/IMS CN/DN data, and Books CN/DN register. Supported formats: Excel (.xlsx, .xls) and CSV. Comma formatting in amount columns is stripped automatically to ensure perfect numeric matching.
Toggle the mode between GSTR-2B vs Books and IMS vs Books. Click "Reconcile" to run our 3-pass purchase matching (with comma-cleaning for amount precision) and 6-pass CN/DN matching algorithms.
Review each record in the results table. Use per-record actions — Accept matched pairs, manually Pair or Force Pair. In IMS mode, filter by IMS Status (Pending, Accepted, Rejected) or supplier GSTIN for rapid validation.
When done, export your reconciliation as a formatted Excel file, a portal-ready IMS JSON file to upload actions back in bulk, or use the Copy ITC Summary button for GSTR-3B filings.
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.
