Stop typing GST invoices in Word
Your accountant hand-types GST invoices in Word or a spreadsheet template, copies the HSN/SAC code, guesses the place of supply, and hopes the tax heads add up. One wrong CGST/SGST split and the customer bounces the bill. There is a better way.

Without it
- ×Accountant types 40 invoices a day in Word — inter-state vs intra-state gets mixed up, CGST+SGST goes where IGST should be
- ×HSN/SAC 9964 vs 9966 confusion — wrong code on a high-value invoice means customer refuses to pay until re-issued
- ×Place of supply errors on a Delhi-to-Gurgaon trip trigger a rejection from the Haryana corporate buyer's AP team
- ×No pre-invoice step — you send the final bill, customer disputes three line items, you issue a credit note and re-issue
- ×e-Invoice mandate crosses your turnover threshold, but you still punch IRN requests manually on the IRP portal
With Travel Softdrive
- Pre-invoice auto-generates the moment a duty closes — rates, taxes, allowances, garage KMs all computed from the rate card
- Customer reviews the pre-invoice, comments inline on any line they dispute, approves — only then does the final invoice lock
- Live IRN and QR code fetched directly via the e-Invoice API — no screen-scraping, no portal hopping
- Place of supply, inter-state vs intra-state, SEZ, RCM — derived automatically from customer GSTIN and trip origin
- Rate snapshot is immutable — once the invoice is raised at ₹14.5/km, nobody can retroactively change the rate card and rewrite history
What's inside
Auto pre-invoice on duty closure
The moment a duty is closed with odometer photos and signed digital duty slip, the pre-invoice is drafted — base fare, extra hours, extra KM, night halt, driver allowance, garage time, GST, all calculated.
Pre-invoice approval chat
Your corporate customer in Bengaluru disputes the 42 extra KM. They comment directly on the pre-invoice. You respond with GPS-backed route data. Resolved inside the invoice, not over 14 emails.
Live e-Invoice IRN generation
Direct integration with the GSTN e-Invoice portal fetches the IRN and signed QR code — your final invoice PDF carries the IRN, acknowledgement number, and verification QR.
Pre → Final → Consolidated chain
Raise 26 daily pre-invoices for a monthly contract, then consolidate them into one final invoice with all supporting line items — the approval trail survives.
Credit & debit notes, linked
Customer short-paid a toll? Generate a credit note linked to the original invoice. Forgot a night-halt charge? Debit note goes in, also linked. GSTR-1 reconciles cleanly.
Rate snapshot immutability
Rates locked at booking creation become part of the invoice's DNA. Even if your rate card changes next week, invoices issued today cannot be retroactively edited.
Digital signature + QR
Every final invoice PDF is digitally signed and carries the e-Invoice QR — your customer's AP team can verify authenticity in 3 seconds.
Third-party invoice mapping
Some corporates require you to print their internal PO number or their own invoice reference on your bill. Map it once, it auto-flows on every invoice for that customer.
A 35-vehicle fleet owner in Pune moves from Word templates to auto-invoicing
A Pune operator with 35 vehicles and four enterprise customers used to spend two full days every month-end generating invoices in Word — copying duty slip numbers, summing KMs on a calculator, guessing whether CGST+SGST or IGST applied, and then manually punching each invoice into the IRP portal for an IRN. One IRN typo on a ₹2.8 lakh monthly invoice held up payment for three weeks. After switching to Travel Softdrive, the moment a duty is closed in the driver app, the pre-invoice auto-drafts with every line item pre-computed. Customer AP teams review on screen, comment on disputed lines, and approve — at which point the system calls the e-Invoice API and returns with IRN and QR embedded in the final PDF. Month-end billing for all four enterprise customers now takes one afternoon, not two days.
Illustrative scenario based on typical operator workflows.
Frequently asked questions
Does the e-Invoice IRN generation require us to log into the IRP portal separately?+
No. We integrate directly with the GSTN e-Invoice ecosystem — IRN and the signed QR code are pulled straight into your final invoice. You never touch the IRP portal for normal operations.
How do you decide CGST+SGST vs IGST?+
Place of Supply is derived from the trip's origin state and your GSTIN state. A Jaipur operator billing a Jaipur corporate gets CGST+SGST; the same operator billing a Delhi customer gets IGST — automatic.
What if a customer disputes a line item on the pre-invoice?+
The pre-invoice has an inline comment thread. The customer flags the specific line (say 'extra KM disputed'), your operations team responds with GPS-backed evidence, and the line can be adjusted before final invoice — no credit notes, no rework.
Can we still edit rates once an invoice is raised?+
The rate snapshot on that invoice is immutable. Your forward rate card can change, but every invoice already raised carries the rates that applied at the time of the booking — prevents retroactive disputes.
We use HSN 9964 and SAC 9966 depending on the duty type — can you handle that?+
Yes. HSN/SAC is mapped at the duty-type level — local, outstation, rental, airport transfer — and auto-populates on the invoice line.
