Clinic bill format: what a receipt must show in India Receipt, bill of supply or tax invoice; the fields, the numbering, and how to correct one.

A clinic receipt in India should show the clinic's name and address, the doctor's name and council registration number, a receipt number from an unbroken series, the date, the patient's name, the service, the amount, and how it was paid: cash, UPI or card. If the clinic is registered for GST, the document for an exempt consultation is a bill of supply, which adds the clinic's GSTIN and a few fixed particulars; taxable items go on a tax invoice. Mistakes are voided with a reason and reissued under a new number, never written over.

Whether the clinic needs GST registration at all is covered in GST on doctor consultation fees, and matching the day's receipts to the drawer, the bank and the card slip is covered in closing the day across cash, UPI and card. This post is about the receipt itself: what goes on it, how it is numbered, and how it is corrected or refunded.

Receipt, bill of supply or tax invoice: which one?

It depends on two things: whether the clinic is registered for GST, and whether what it is billing is exempt. Consultation and treatment are exempt: serial number 74 of Notification No. 12/2017-Central Tax (Rate), 28 June 2017, puts "health care services by a clinical establishment, an authorised medical practitioner or para-medics" at a Nil rate. The invoicing rules in section 31 of the CGST Act, 2017 are written for a "registered person", so they bind a clinic only once it has a GSTIN.

Section 23(1)(a) of the CGST Act says a person "engaged exclusively in the business of supplying goods or services or both that are not liable to tax or wholly exempt from tax" is not liable to register. Most consultation-only clinics are in the first row. The moment the clinic sells something taxable, the question changes; the GST post goes through how.

What a clinic receipt should show

The table below is a clinic bill format built from the two sources that apply: the professional conduct regulations, which apply to every doctor, and rule 49 of the CGST Rules, which applies only to a registered clinic's bill of supply. Fields marked as practice are not required by either; they are what makes the receipt useful at the 8 PM close and at the CA's desk in April. The example column uses a sample clinic.

Regulation 1.4.1 of the Indian Medical Council (Professional Conduct, Etiquette and Ethics) Regulations, 2002 reads: "Every physician shall display the registration number accorded to him by the State Medical Council / Medical Council of India in his clinic and in all his prescriptions, certificates, money receipts given to his patients." The National Medical Commission adopted the 2002 regulations as its own on 23 August 2023, when it held its 2023 conduct regulations in abeyance. In a multi-doctor clinic, that means the receipt carries the number of the doctor who saw the patient, not only the owner's.

The same regulations deal with the fee itself. Regulation 1.8 says a physician "should announce his fees before rendering service" and that remuneration "should be in the form and amount specifically announced to the patient", and regulation 3.7.1 asks for fees and other charges to be displayed "on the board of his chamber". The receipt is where the announced fee and the collected fee meet, which is why a waiver or discount belongs on its own line rather than as a smaller number in the amount box.

How to number receipts

For a registered clinic, rule 49(b) fixes the format: "a consecutive serial number not exceeding sixteen characters, in one or multiple series, containing alphabets or numerals or special characters - hyphen or dash and slash ... unique for a financial year". An unregistered clinic is not bound by it, but it is a sound rule for any receipt book.

• Start a new series each financial year, on 1 April. A prefix with the clinic's initials and the year (SC/26-27/0001 is 13 characters) keeps it under 16.
• "Multiple series" is allowed. A clinic with two doctors can run SC-A/26-27/ and SC-B/26-27/, or keep one series for consultations and another for procedures. Decide at the start of the year and write it down.
• A number is used once. A cancelled receipt keeps its number and is marked void; the number is not reissued.
• With paper books, keep the carbon or counterfoil of every receipt, including the spoiled ones. A missing page in a numbered book is the first thing an auditor asks about.

Small fees under ₹200

Section 31(3)(c) has a proviso: a registered person "may not issue a bill of supply if the value of the goods or services or both supplied is less than two hundred rupees subject to such conditions" as prescribed. Rule 49 says the provisos to rule 46 apply to bills of supply "mutatis mutandis", and the matching rule 46 proviso sets the conditions: the recipient is not registered, the recipient does not require the document, and a consolidated document is issued "at the close of each day in respect of all such supplies". Read together, a registered clinic can put a ₹150 dressing charge on one end-of-day consolidated bill instead of a separate bill; confirm the reading with your CA. Most desks still hand the patient a receipt anyway, because patients ask for one and the receipt is what carries the doctor's registration number.

Correcting a receipt without overwriting it

For a registered clinic, rule 56(8) of the CGST Rules is explicit: "Any entry in registers, accounts and documents shall not be erased, effaced or overwritten, and all incorrect entries, otherwise than those of clerical nature, shall be scored out under attestation and there after the correct entry shall be recorded and where the registers and other documents are maintained electronically, a log of every entry edited or deleted shall be maintained." An unregistered clinic should work the same way, because it is the only way a correction can be told apart from a missing fee.

1. Do not change the amount on a receipt already issued. Mark it void, with the reason, the time and who voided it.
2. Issue a new receipt under the next number, and write the voided number on it ("replaces SC/26-27/0041").
3. On paper, strike through once so the original stays readable, sign beside it, and keep both copies in the book.
4. In software, the voided receipt should stay visible in the day's list and the day book, with its reason. If the software lets the desk edit a saved amount without a trace, that is a gap to raise with the vendor.
5. The owner reads the day's voids at the close. A void is normal; a pattern of voids on cash receipts is a question.

A tax invoice that has already gone into a GST return is corrected differently: section 34 of the CGST Act provides for credit and debit notes. That is a question for the CA, and it only arises for the taxable side of a registered clinic.

Refunds

A refund is its own entry, not a deleted receipt. Record it against the original receipt number with the date, the amount, the mode it was paid back in, the reason and who approved it. Pay it back in the mode it came in where you can: a UPI fee refunded in cash from the drawer leaves the drawer short and the bank statement overstated, and the closing sheet will show a mismatch that nobody can explain a week later.

Advances are the one case GST names. Section 31(3)(d) says a registered person "shall, on receipt of advance payment with respect to any supply of goods or services or both, issue a receipt voucher or any other document", and section 31(3)(e) allows a refund voucher when no supply follows. Rules 50 and 51 list their particulars. A registered clinic that takes deposits for procedures should ask its CA how this applies to its exempt and taxable services.

The cash limit on a single bill

Since 1 April 2026, section 186(1) of the Income-tax Act, 2025 bars receiving ₹2,00,000 or more in cash from a person in a day, for a single transaction, or for transactions relating to one event or occasion. Section 451 lets the Assessing Officer impose a penalty equal to the sum received. For a receipt book this means a procedure bill at or above ₹2,00,000 is paid by account payee cheque, draft, bank transfer or another prescribed electronic mode, and splitting it across several cash receipts for the same procedure does not help. The closing-the-day post also covers the ₹10,000 limit on cash expenses.

The day book and keeping copies

The day book is the list of every receipt issued that day, in number order, including voids and refunds. Section 62(1) of the Income-tax Act, 2025 requires any person carrying on a specified profession, which section 62(4) defines to include "medical", to "keep and maintain such books of account and other documents to enable the Assessing Officer to compute his total income". Section 2(19) says books of account include "ledgers, day-books, cash books", whether kept on paper, electronically or on cloud storage. The specific books, their particulars and how long to keep them are left to rules under section 62(3); ask your CA which apply to your practice.

A GST-registered clinic has a fixed retention rule as well. Section 36 of the CGST Act says accounts and records kept under section 35(1) are retained "until the expiry of seventy-two months from the due date of furnishing of annual return for the year pertaining to such accounts and records", and longer where an appeal or investigation is pending.

Paper receipt book or clinic billing software

A numbered carbon book with a rubber stamp for the registration number works. It fails in three places: the mode is rarely written, totals by mode take a calculator at night, and a torn-out page leaves no trace. When you look at clinic billing software, check these points before anything else:

• Receipt numbers are generated in sequence and cannot be reused or reset mid-year.
• The doctor's registration number prints on every receipt, per doctor in a multi-doctor clinic.
• Payment mode is a required field on every receipt.
• A saved amount cannot be edited; corrections are voids with a reason, and voids stay visible.
• Refunds are recorded against the original receipt.
• The day book totals by mode, and the full list exports for the CA.
• If you sell taxable items, the software issues a proper tax invoice for them. Vitels, for one, bills consultation fees only.

Where Vitels fits

In Vitels clinic billing software the desk records each consultation fee as cash, UPI or card, prints an A5 receipt, and gets an A4 day book with revenue by doctor. A saved amount cannot be edited: a mistake is voided with a reason, and billing keeps working with no internet. The clinic admin can export everything as CSV for the CA. Vitels bills consultation fees only; it does not issue GST tax invoices for goods.

Receipt checklist for the front desk

1. Clinic name and address, and the doctor's registration number, on every receipt.
2. GSTIN and the bill of supply particulars, only if the clinic is registered.
3. Next number in the series; never a reused or handwritten-over number.
4. Date, patient name, service, amount, waiver or discount on its own line.
5. Mode: cash, UPI with reference, or card.
6. Mistake: void with reason, reissue under a new number, keep both.
7. Refund: its own entry, against the original receipt, in the original mode.
8. Any cash bill at or above ₹2,00,000 for one procedure: not in cash.
9. At closing: the day book in number order, voids and refunds included, goes to the owner.
