GST rules keep moving. Your software should keep up.

The e-Invoice threshold dropped to 5 crore. RCM still applies on unregistered supplier cars. LUT is renewed every financial year for export bookings. SEZ customers need zero-rated invoices. One spreadsheet template can't handle all of it. We do.

Without it

  • ×e-Invoice crossed your turnover threshold — your accountant now manually punches every B2B invoice into the IRP portal and copy-pastes the IRN
  • ×A Mumbai-based supplier's car is unregistered — you forget RCM applies, month-end GSTR reconciliation fails
  • ×SEZ customer in Noida — you raise a normal tax invoice instead of zero-rated under LUT, customer's AP team rejects
  • ×LUT expired 8 months ago and nobody noticed — you've been raising export invoices with IGST that you should have issued under LUT
  • ×Place of Supply for a Delhi-pickup Gurgaon-drop gets typed wrong, CGST+SGST goes where IGST should — bill stuck in dispute

With Travel Softdrive

  • Live IRN generation via e-Invoice API — the IRN and signed QR land on the final invoice the moment it's raised
  • RCM register tracks every duty involving an unregistered supplier — GSTR-3B reconciliation is clean
  • LUT document tracking — upload the LUT, tag the financial year, get reminded 30 days before expiry
  • SEZ billing recognized from customer GSTIN — invoice raised as zero-rated, LUT reference number stamped
  • Place of Supply derived automatically from origin state and your GSTIN state — CGST+SGST vs IGST is never a judgement call

What's inside

Live e-Invoice IRN + QR

Direct integration with the GSTN e-Invoice portal pulls IRN and the signed QR code. Your invoice PDF carries them embedded. No manual portal work.

Place of Supply, automated

Computed from the trip's pickup state and your registered GSTIN state. Inter-state trips get IGST, intra-state get CGST+SGST — correctly, every time.

RCM handling for unregistered suppliers

When you use an unregistered partner's car, RCM is flagged on the purchase side. GSTR-3B reconciliation picks it up clean — no missed reverse-charge liability.

LUT document lifecycle

Upload your Letter of Undertaking, tag the financial year, get the ARN. LUT reference auto-stamps on every export invoice. Expiry alert 30 days before FY-end.

SEZ billing out of the box

SEZ customer GSTINs are detected; invoices raised as zero-rated with LUT reference. No manual 'is this SEZ or not' checking by the accountant.

HSN/SAC at duty type

HSN 9964 for passenger transport, SAC 9966 for rental services — mapped to your duty types so the right code lands on the right invoice.

Digital signature on every invoice

Every final invoice PDF is digitally signed. The QR code verifies authenticity on the GSTN portal in 3 seconds for the customer's AP team.

Compliance tracker + FY switch

Financial year management, compliance item tracking (insurance, fitness, PUC, permit), e-invoice readiness dashboard — all in one compliance view.

In the real world

An export-focused Kolkata operator crosses the e-Invoice threshold mid-FY

A Kolkata operator with a large corporate book — including two SEZ customers in Rajarhat and one in the Salt Lake IT sector — crossed the 5 crore e-Invoice threshold mid-FY24. Their existing billing was a Word template and manual IRP portal punching. Within weeks, reconciliation errors on GSTR-1 and missed RCM entries on unregistered partner cars started piling up. After moving to Travel Softdrive, e-Invoice IRN and QR land on every B2B invoice the moment it's raised — no portal visits. Their LUT, already uploaded at the start of the FY, auto-stamps on every SEZ invoice as zero-rated. RCM on an unregistered Howrah supplier's car is flagged on the purchase side and shows up clean on the 3B. Their compliance dashboard shows every document — vehicle fitness, insurance, permits, LUT — with expiry status. Month-end GST reconciliation dropped from a week of back-and-forth between the accountant and the operations team to one afternoon.

Illustrative scenario based on typical operator workflows.

Frequently asked questions

We are below the 5 crore e-Invoice threshold — do we still benefit?+

Yes. Place of Supply, RCM, LUT, SEZ, HSN/SAC, CGST/SGST/IGST splits all happen regardless of e-Invoice applicability. When you cross the threshold later, e-Invoice IRN just turns on — no re-platforming.

Do you support LUT renewal reminders?+

Yes. Upload the LUT with the FY tag, and you get alerts 30 days before the fiscal year-end so the renewed LUT is in place on April 1.

How is RCM reconciled?+

Every duty involving a supplier marked 'unregistered' carries an RCM liability entry on the purchase side. Your 3B reconciliation pulls these in automatically — the accountant doesn't manually hunt for them.

What happens if the e-Invoice portal is down when we generate a final invoice?+

The invoice is raised and marked 'IRN pending'. As soon as the portal is back, the IRN fetches automatically and the PDF regenerates with IRN and QR.

Can we issue credit notes with IRN?+

Yes. Credit and debit notes are e-Invoice compliant — IRN and QR on those too, linked to the original invoice for GSTR-1 tracking.
