A salon GST invoice must show your name, address and GSTIN; a consecutive invoice number of up to 16 characters, unique for the financial year; the date; the client’s details (name and address are compulsory from ₹50,000); the SAC or HSN code; a description; the taxable value after discount; the CGST and SGST rates and amounts; whether reverse charge applies; and a signature, unless the bill is electronic. The list comes from Rule 46 of the CGST Rules. Refunds and corrections go on a numbered credit note, and for any financial year those stop on 30 November after it ends.
This guide explains the rules in plain words; it isn’t tax advice. Check your own case with your CA.
The salon GST invoice format: a Rule 46 checklist
| Rule 46 asks for | On a salon bill, that means |
|---|---|
| Your name, address and GSTIN | The legal name and address on your registration certificate, and the GSTIN of that branch’s state |
| A consecutive serial number | Up to 16 characters: letters, numbers, “-” and “/”. Unique for the financial year. You can run more than one series, for example one per branch |
| Date of issue | The day of the bill |
| Client details | A registered client: name, address and GSTIN. A client who isn’t registered: name, address and state from ₹50,000 of taxable value; below that, only if they ask |
| HSN or SAC code | 9997 for services; the product’s HSN for goods. Optional on bills to unregistered clients if your turnover is up to ₹5 crore |
| Description, and quantity for goods | “Global colour”, “Shampoo 250 ml × 1” |
| Total value and taxable value | The price, any discount, and the value after discount that GST is worked out on |
| Rate and amount of tax | CGST 2.5% and SGST 2.5% for services, with the rupee amounts; 5% or 18% for products |
| Place of supply | Needed for inter-state supplies. A service done in your salon is supplied in your own state |
| Reverse charge | “Reverse charge: No” on salon bills |
| Signature | A signature or digital signature, not needed on an electronic invoice |
A sample bill, line by line

Sample bill on demo data
- Top: salon name, address, GSTIN and the words “Tax invoice”.
- Number and date: DS/26-27/00042 is 14 characters: a short prefix, the financial year and a running number.
- Lines: each service with its price.
- Taxable value, CGST, SGST: the tax split in half, shown in rupees.
- Round off and total: the bill is rounded to the rupee on a separate line.
- Foot: the SAC and a line saying the bill is computer-generated.
Invoice numbers: short, in order, never reused
The number is where most home-made formats go wrong. Rule 46 says it must be consecutive, at most 16 characters, and unique for the financial year (April to March). A good pattern is PREFIX/YY-YY/NNNNN, with a prefix of 2 to 4 letters, so DS/26-27/00042. Long branch names in the prefix push you over 16 characters.
- Start again each April, or keep counting. Either works, as long as no number repeats within a year.
- Never delete a bill. A mistake is cancelled with a reason and stays in the series. Your CA reports how many numbers were used and how many were cancelled.
- Separate series are allowed for credit notes, fee invoices or branches, each with its own prefix.
The law also lets you skip a bill for an unregistered client who doesn’t want one and issue one consolidated invoice at the end of the day. For a salon a bill each time is simpler and better: the client gets a record, and your staff’s sales are tied to real bills.
The ₹50,000 rule for bridal and big bills
When an unregistered client’s bill has a taxable value of ₹50,000 or more, the invoice must carry their name and address, the delivery address and the state with its code. For a salon that is mostly bridal packages, big group bookings and large prepaid packages. Take the address before you charge, not after. Below ₹50,000 you only add these details if the client asks.
Business clients sometimes ask for their GSTIN on a beauty bill. The law blocks input tax credit on beauty treatment for most businesses, so it rarely helps them. Frizzi doesn’t put a client’s GSTIN on bills.
Tax invoice or bill of supply?
- Registered salon, normal scheme: a tax invoice with GST on every taxable line. Salon services aren’t exempt, so this is the usual case.
- Registered salon on the composition scheme: a bill of supply (Rule 49). It carries no GST because you can’t collect tax from clients under composition.
- Salon that isn’t registered: no GSTIN and no tax on the bill. Strictly, Rule 49 is written for registered sellers of exempt goods or on composition. For an unregistered salon, a plain numbered bill is fine; ask your CA if the heading matters.
Credit notes for refunds and late cancellations
When you refund a client or cancel a bill from an earlier month, you don’t change the old invoice. You issue a credit note (section 34, Rule 53). It needs:
- your name, address and GSTIN, and the words “Credit note”
- its own consecutive number of up to 16 characters, unique for the year
- its date
- the client’s name and address (and state, for an unregistered client)
- the number and date of the original invoice
- the taxable value, the rate and the tax being credited
- a signature, or the electronic equivalent
A bill cancelled in the same month is simply marked cancelled. From an earlier month, it gets a credit note, which lowers the GST in the month the note is issued.
The 30 November deadline. A credit note for a supply must be shown in a return by 30 November after the end of that financial year, or by the date you file the annual return, if that is earlier. For bills from April 2025 to March 2026, that means 30 November 2026 at the latest. After it, you can still give the money back, but the GST already paid stays paid.
How Frizzi’s bills follow the format
Frizzi numbers bills per company and financial year (DS/26-27/00001). The prefix is 2–4 characters, so a number never passes 16, and numbers never repeat or skip. Each bill shows your legal name, address and GSTIN, “Reverse charge: No”, the client, lines with price, discount and GST rate, the taxable value, a GST summary by SAC or HSN and rate, the round-off, how it was paid and a computer-generated line. From ₹50,000 with GST, the till won’t charge without the client’s name and address; that is a little stricter than the law.
Bills are never deleted. A cancelled bill from an earlier month gets a numbered credit note (DS/CN26-27/0001), refunds make one too, and after 30 November Frizzi gives a refund receipt instead. Without a GSTIN, the bill prints as a bill of supply with no tax. Read more on billing and GST and the till, and see what to check in a salon POS.
Questions
Does a walk-in client need to give their name on a GST bill?
Not below ₹50,000 of taxable value, unless they ask for it. From ₹50,000, an unregistered client’s name, address and state must be on the invoice.
Can I start invoice numbers from 1 every April?
Yes. Numbers must be consecutive and unique within a financial year, so restarting each April is fine, and so is a running count. Keep each number to 16 characters or fewer.
Does a printed thermal bill need a signature?
Rule 46 asks for a signature or digital signature, but not on an invoice issued electronically under the IT Act. Most billing software prints a “computer-generated” line; if you rely on printed slips only, confirm the wording with your CA.
What happens if I refund a client after 30 November?
You can still return the money, but you can no longer issue a credit note to reduce the GST for a supply from the previous financial year. The tax you paid on that bill stays paid.
