GST compliance
How the GSTgets done.
What Varynt Invoice decides for you, what it prints, and, just as plainly, what it does not do.
This page explains how the product behaves. It isn't tax advice; your CA has the last word on your own filings.
No. 01Tax type
The place of supply decides.
It defaults to the client's billing state, which the GSTIN already told us, and you can change it on any document. Each line carries its own rate from your list of rates.
Seller registered as Regular, client in the same state
→ CGST + SGST, each half the rate
Seller registered as Regular, client in another state
→ IGST, the whole rate
Seller under Composition, or not registered
→ No tax lines at all
Rates are yours to keep current: your list starts with 0, 5, 18 and 40% switched on, and 12% and 28% kept for older invoices, and you switch slabs on and off as notifications change. A document charges only a notified slab: 0, 0.25, 3, 5, 12, 18, 28 or 40%, so gold and silver at 3% and diamonds at 0.25% can be invoiced.

| Packaging artwork | 36,000.00 | 6,480.00 | 42,480.00 |

- IGST 18%
- 16,200.00
- Total (₹)
- 1,06,200.00
The total is the same either way. What changes is who collects the tax — both states, or the Centre.
No. 02Registration
Regular, Composition, or not registered.
Set once in your business details. It decides the title at the top of every document and whether tax lines appear at all.
Regular
Tax invoice
The full tax invoice: CGST and SGST, or IGST, line by line, with the HSN summary underneath.
- Taxable value
- CGST 9% / SGST 9%
- Total
Composition
Bill of supply
Composition sellers can't collect tax, so there are no tax lines. The declaration the law asks for is printed for you.
- Amount
- Total
- “Composition taxable person, not eligible to collect tax on supplies.”
Not registered
Invoice
Below the threshold, or not registered for another reason? You still send a proper, numbered invoice, without GST.

No. 03Numbering
Numbers the law will accept.
One series per document type, restarting every financial year. These rules are enforced by the product, not left to whoever issues the invoice.
INV/25-26/0318
31 Mar 2026 · last of FY 2025-26
INV/26-27/0001
1 Apr 2026 · first of FY 2026-27
Consecutive
Allocated in order inside the issue itself, so two people issuing at once never get the same number
At most 16 characters
INV/26-27/0042 is 14
One series per financial year
April to March, taken from the invoice's own date
Allocated at issue
A draft has no number. Quotations, credit notes, purchase orders and vendor credits have series of their own
Never reused
Cancelling keeps the number, marked cancelled, so there is no gap
One series per branch
Where you bill from several GSTINs, each branch numbers on its own prefix (MUM/26-27/0001)
Dated in order
An issue date can't be in the future, or earlier than the last issued invoice
No. 04What's printed
Every field Rule 46 asks for.
The tax invoice rules list what an invoice must carry. Each one has a fixed place on the sheet and is filled from what you already entered.
Plus what makes it usable: the amount in words in lakh and crore, the HSN summary, and a round-off line if you round to the rupee.
No. 05Lines that aren't simple
Nil, exempt, non-GST, and cess.
Two things most businesses never meet and some meet on every invoice. Both are recorded per line, and both stay out of the way of everyone who doesn't need them.
Nil-rated, exempt or non-GST, per line
A 0% line is one of three different things in GSTR-1 table 8, so the editor records which. Per line, because one invoice often carries a taxable service beside an exempt one.
Compensation cess on notified goods
Ad valorem, a fixed amount per unit, or both, charged as the sum or the higher of the two, as the notifications set it. One amount beside GST, never split between centre and state.
Invisible until you need it
A workspace that never creates a cess rate never sees a cess field, and its figures are exactly what they were.
Reverse charge
On a sale, the invoice says tax is payable on reverse charge and charges none. On a purchase, the tax is still computed and claimable, and the vendor is owed less than the bill says.
No. 06Input tax credit
Decided per line, not per bill.
One real bill carries a claimable service and a car hire the law blocks outright, so a flag on the whole document would be wrong on most bills anybody actually receives.
Claimable
The ordinary case: tax your supplier charged you, on something the business bought for the business.
Not claimable
Real tax, but not yours to set off: a staff lunch, something bought for personal use.
Blocked under s.17(5)
The law refuses it outright, whatever it was for. Rent-a-cab is the one every business meets first.
Claimable plus not claimable plus blocked equals the tax on your bills, so the ITC summary reconciles against the purchase register. How purchases work →

No. 08Questions
Asked before buying.
01Does it do e-invoicing (IRN) or e-way bills?
No. Varynt Invoice does not register invoices with the IRP, so nothing it produces carries an IRN or a signed QR, and it raises no e-way bills. If your turnover puts you above the e-invoicing threshold, you would need a separate IRP utility alongside it, so it probably isn't the right fit for you today.
02Does it file my GSTR-1?
No. It produces the sales register and a GST summary split the way GSTR-1 splits it, which your CA uses to prepare the return. Filing stays with you and your CA.
03I'm under the Composition scheme. Can I use it?
Yes. Your documents are titled Bill of Supply, carry no tax lines, and print the declaration that you are a composition taxable person not eligible to collect tax.
04I'm registered in more than one state.
Each branch carries its own GSTIN, address, invoice series and bank. The branch you bill from decides the seller's state.
