An invoice for services, with the SAC code and the place-of-supply question settled
Estimates only, not financial advice. What you type stays on your device. Checked against sources on 25 Sept 2026.Billing services rather than goods changes two things. The code is a SAC rather than an HSN, and the place of supply is often not the address on the buying company letterhead, which decides whether you charge CGST and SGST or IGST. Both are asked for separately here rather than guessed from the billing address.
Rates and rules read from the sources listed on this page (the earliest on 25 Sept 2026); they may have changed since.

A tax invoice is a legal document with a specified content list, and two things go wrong on hand-made ones often enough to be worth building a tool around.
Section 7 of the IGST Act compares the location of the supplier with the place of supply. Same state, and the tax is CGST and SGST at half the rate each; different ones, and the whole rate is IGST. Neither is the buyer's billing address. A Delhi consultant invoicing a Mumbai head office for work delivered in Delhi is supplying within one state and should charge CGST and SGST; a generator reading the letterhead will put IGST on it. This page asks for your state and the place of supply separately, says which rule it applied, and flags a buyer registration that does not match.
Rule 46 lists the particulars, lettered (a) to (s): your name, address and GSTIN; a serial number of at most sixteen characters using only letters, numerals, hyphens and slashes; the date; the buyer's details; the HSN or SAC code; a description; quantity and unit; total and taxable values; the rate; the tax; the place of supply with its state; the delivery address where it differs; whether reverse charge applies; and a signature. Every clause is quoted here from CBIC's own text and your invoice is checked against them, so anything missing is named by its letter.
The rest of the article, and all 7 questions about GST Invoice Generator, are on the GST Invoice Generator page.
Compare your own location with the place of supply. Same state or union territory means CGST and SGST at half the rate each; different ones mean the whole rate as IGST, under section 7 of the IGST Act. The buyer's billing address does not decide it, which is where most hand-made invoices go wrong.
Rule 46 of the CGST Rules lists nineteen particulars: your name, address and GSTIN, a serial number, the date, the buyer's details, the HSN or SAC code, a description, quantity and unit, total and taxable value, the rate, the tax charged, the place of supply with its state, the delivery address where it differs, whether reverse charge applies, and a signature.
Is page par seller, buyer, place of supply aur har line ka HSN, rate daal kar bill kaise banaye yeh apne aap ho jaata hai. The tax split, the HSN summary, the round-off line and the amount in words are all generated, and the invoice is checked clause by clause against Rule 46 before you print it.
Rule 46(g) asks for the Harmonised System of Nomenclature code for goods, or the Service Accounting Code for services, and how many digits are required depends on your turnover. This page marks any line without one, because a missing code is the commonest reason an otherwise correct invoice is queried.
