Medical Store (Pharmacy) Bill Format: Fields and Sample

Picture a customer returning to your counter two weeks later: their insurer wants proof of the antibiotics they bought, and the manufacturer has just recalled one batch of that brand. A proper pharmacy bill format answers both problems in seconds, because it records the medicine, batch number, expiry date, prescribing doctor and price for every line.

This guide explains what a medical store bill must contain, shows a filled chemist bill with the GST worked out from MRP, and lists the format mistakes that cause trouble with customers, insurers and inspectors. It focuses on India, where most "medical store bill format" searches come from, with notes for other countries at the end.

What is a pharmacy bill?

A pharmacy bill (also called a chemist bill, medical store bill or cash memo) is the sales document a retail pharmacy issues when it dispenses medicines and health products. It does two jobs at once: it is a tax document for GST, and it is a dispensing record that ties each pack to a manufacturing batch. That second job is why a medical bill has more columns than an ordinary GST invoice.

Indian drug rules require retailers to keep records of sales, and allow the batch number, expiry date and manufacturer of drugs sold from original packs to be recorded in serially numbered cash or credit memos rather than a separate register. You can read the rules in the Drugs and Cosmetics Rules, 1945. In practice, almost every computerised pharmacy prints these fields directly on the bill.

Pharmacy bill format: fields to include

Shop details

• Pharmacy name, full address and phone number.
• Drug licence numbers (retail sale licences, usually in Form 20 and 21 for allopathic drugs).
• GSTIN, if registered.
• Name of the registered pharmacist on duty, which many stores print in the footer.

Bill and patient details

• Bill number in a continuous series, date and time.
• Patient name and, for prescription drugs, the prescribing doctor's name and registration number if available.
• Customer phone number, useful for refill reminders and recalls (with consent).

Medicine lines

• Product name with strength and pack (Amoxicillin 500 mg, 10 caps).
• Manufacturer or marketer.
• HSN code (registered dealers). Our HSN code guide explains how many digits to show.
• Batch number and expiry date (month/year).
• Quantity, MRP, discount percentage and net amount.
• Schedule marker (H, H1) on prescription-only items, which helps staff check a prescription was seen.

Footer

• Gross total, discount, taxable value, CGST and SGST, round-off and net payable.
• Payment mode.
• Return policy, for example "Unopened, uncut strips returnable within 7 days with bill. Refrigerated items not returnable."
• Pharmacist's signature or e-signature.

Sample medical store bill

CareWell Pharmacy, 4 Station Road. DL No: 20-XXXX / 21-XXXX. GSTIN: (shown). Tax Invoice. Bill No. CWP/2026-27/11934. Date: 12 Nov 2026, 11:05. Patient: R. Mehta. Doctor: Dr S. Iyer (Reg. No. shown).

Product	Pack	Batch	Exp	Qty	MRP (Rs)	Amount (Rs)
Paracetamol 650 mg tab	15 tabs	PCM2409	08/27	2	33.00	66.00
Amoxicillin 500 mg cap (Sch. H)	10 caps	AMX5531	03/27	2	112.50	225.00
Cough syrup	100 ml	CS7710	01/27	1	145.00	145.00
ORS sachet	21 g	OR1182	06/28	4	22.00	88.00
Gross (at MRP)						524.00
Discount 10%						-52.40
Net value (tax inclusive)						471.60
Taxable value						449.14
CGST 2.5%						11.23
SGST 2.5%						11.23
Round off						+0.40
Net payable						472.00

How the numbers work: MRP is tax-inclusive, so after the 10% discount the customer pays 471.60 including GST. Assuming every item in this example is at 5%, the taxable value is 471.60 / 1.05 = 449.14 and the tax is 471.60 - 449.14 = 22.46, split equally into CGST and SGST of 11.23 each. A 0.40 round-off brings the payable amount to 472. On a real bill, each item uses the rate for its own HSN code, and tax is calculated line by line.

GST on medicines: what changed

The GST Council's rate rationalisation from 22 September 2025 cut tax on most medicines. According to the official press release on the 56th GST Council meeting, 33 life-saving drugs moved from 12% to nil, three drugs for cancer, rare diseases and severe chronic conditions moved from 5% to nil, and other drugs moved from 12% to 5%. For a pharmacy, that means two practical things:

• Your billing software's product master needs the correct rate per HSN code, not one blanket rate.
• Older stock carries MRPs printed under the old rates. The tax on your bill follows the rate in force on the date of sale, not the rate when the pack was made.

Rates can change again, so confirm current rates with your distributor's invoices or a tax adviser. This section is general information, not tax advice.

How to create a pharmacy bill, step by step

1. Check the prescription for any Schedule H or H1 item and note the doctor's name before billing.
2. Scan or select each product. Pick the batch you are actually handing over; good software defaults to the earliest expiry (first expiry, first out).
3. Confirm the expiry is well after the patient's course ends. Never bill an expired batch.
4. Enter quantity in the right unit. If you cut a strip, bill tablets proportionally: 5 tablets from a 15-tablet strip with MRP 33 cost 11.00.
5. Apply discount as a percentage of MRP and show it on the bill.
6. Let the software split tax by rate, then round off once.
7. Print two copies or send a digital copy, and keep your copy with the prescription reference.

Medical bill format variations

Hospital pharmacy bills

In-patient pharmacy charges are usually summarised on the final hospital bill with a detailed annexure listing every item. Our hospital bill format guide shows how those annexures fit into the main bill.

Bills for insurance or reimbursement

Insurers and employers often reject pharmacy bills without a patient name, doctor name or matching prescription date. Print all three, and keep the bill date close to the consultation date. A doctor consultation receipt plus the pharmacy bill is the usual pair for a claim.

Bills from clinics that dispense

Doctors who dispense from their own clinic often combine consultation and medicines on one document. Separate the two sections clearly, because consultation fees and medicines are treated differently for tax. The structure of a clinic bill is covered in our medical invoice template guide.

Returns and credit notes

When a customer returns unopened stock, do not edit the old bill. Issue a return entry or credit note that references the original bill number and batch, refund the amount, and put the stock back into the right batch. Our guide to the refund invoice covers the paperwork, and keeping a stock register by batch makes the return easy to trace.

Common mistakes on pharmacy bills

• Missing batch or expiry. Without them, a recall becomes guesswork.
• Billing above MRP or charging GST on top of an already tax-inclusive MRP.
• One GST rate for everything after the 2025 changes.
• No patient or doctor name on prescription items, which makes the bill useless for insurance.
• Handwritten bills without serial numbers, which break the continuous record that drug and tax rules expect.
• Selling loose tablets at a rounded-up price rather than the proportional MRP.

Outside India

In the UK, NHS prescription items are not sold on a normal retail bill, but private prescriptions and over-the-counter sales are, and most medicines dispensed on prescription are zero-rated for VAT while many OTC products are standard-rated. In the US, prescription drugs are generally exempt from state sales tax while many OTC items are taxable, and receipts for HSA or FSA claims should list the product name and date. In Pakistan, pharmacies that fall within the Tier-1 retailer rules must issue FBR-integrated POS invoices. The core fields, batch, expiry, patient, prescriber and price, are useful everywhere.

Pharmacy bill template you can copy

If you are setting up billing software or a printed bill book, this field order works well on an A5 page or an 80 mm thermal roll:

1. Pharmacy name, address, phone, drug licence numbers, GSTIN.
2. Heading (Tax Invoice or Cash Memo), bill number, date and time.
3. Patient name, phone, doctor name and registration number.
4. Item table: product and strength, pack, manufacturer, HSN, batch, expiry, quantity, MRP, discount, amount.
5. Tax summary by rate: taxable value, CGST, SGST.
6. Round-off, net payable, payment mode.
7. Return policy and pharmacist signature.

On thermal rolls, put manufacturer and HSN on a second line under the product name to keep columns readable. On A5 bills, keep batch and expiry in their own columns, because those are the fields staff look for first during a recall or a return.
