Live Interactive SandboxTest drive this module

Manual GST reconciliation across multiple GSTINs leads to missed input tax credit (ITC) and costly notice inquiries. Pyngyn connects directly to GSTN via authorized GSPs to streamline monthly reconciliations.

21. Authorized GSP Direct Integration

Connect client GSTIN portals using secure OTP authorization and 30-day session tokens. ClientSpace executes automated background data syncs at 04:00 AM every morning to pull the latest GSTR-2B returns.

32. Automated 3-Way ITC Matching

The reconciliation engine automatically compares invoices from your accounting software purchase register with government GSTR-2B records, bucketing transactions into 4 actionable categories:

  • Matched: Invoice number, date, GSTIN, taxable value, and tax amounts match within ₹5 tolerance.
  • Missing in 2B: Invoices in your client's books where the vendor has failed to file GSTR-1.
  • ITC Ineligible / Blocked: Invoices categorized under Section 17(5) or reverse charge mechanisms.
  • Value Discrepancy: Invoices matching on invoice number but differing in tax rate or value.

43. Automated Vendor Follow-Ups via WhatsApp

When missing GSTR-2B invoices threaten your client's input tax credit, ClientSpace can auto-generate and dispatch professional WhatsApp reminders directly to non-compliant vendors requesting filing confirmation.

54. Return Filing & ARN Archive

After partner sign-off, filing acknowledgments (ARN receipts) and PMT-06 challans are automatically archived into the client's permanent GST document vault for year-end audit retrieval.
