This page covers what billing in this trade actually involves, what to check in anything sold as pharmacy billing software, and a free plan you can test the whole thing on without a card.
What is the same in every trade
Whatever you sell, if you are registered and making a taxable supply the document is a tax invoice and the field set does not change: your name, address and GSTIN; a consecutive number unique within the financial year; the date; the customer and their GSTIN where registered; place of supply on inter-state supplies; HSN or SAC against every line; the taxable value per line; and CGST, SGST/UTGST, IGST and cess shown separately rather than as one combined tax figure.
The numbering rule is the one that causes the most trouble in practice, because it cannot be enforced by a person. One consecutive series per year, no reused numbers, and a cancelled invoice keeps its number rather than giving it back.
Rates, thresholds and the scope of e-invoicing have all moved and will move again. Nothing here states a current figure for that reason — check the notification in force for your own turnover.
Pharmacy and medical shop billing
A chemist's invoice is a goods invoice with the trade's own record-keeping layered on top, and the layer is not optional.
Every line wants its batch number and expiry date, because that is how a return to the distributor or a recall is traced, and because expiry is the stock loss in this trade. Stock is therefore batch-wise rather than item-wise — the same medicine in two batches is two stock positions with two expiry dates, and billing from the wrong one is how expired stock reaches a customer.
Pharmacy stock also sits at more than one rate, with medicines, devices and ordinary retail goods on the same bill, so per-line tax is the only correct treatment. Part-strip sales, substitutions and the distributor's own scheme discounts are all routine and all need to survive onto the bill honestly.
What this does not do, and it matters here: it is not a substitute for the records your drug licence requires, and it does not file anything with a licensing authority. Those obligations sit alongside the tax ones. If you need prescription-wise dispensing records for a licence condition, check that specifically.
What you get on the free plan
- Complete GST tax invoices with every legally required field, not a template with a tax box.
- Customers and items stored once, with GSTIN, state, HSN or SAC and rate held against them.
- Tax derived rather than typed — per line, from the item rate and the place of supply.
- One numbering series, issued centrally and consecutive within the financial year.
- Stock that moves as you bill, so a closing figure means something.
- An answer to "who owes me what", aged, without adding anything up.
- PDF invoices to print, email or send on WhatsApp.
- Full export — CSV, Excel and JSON, on every plan including the free one.
- ₹0, no card, no expiry.
Judging any billing system in half an hour
- Load ten of your own items, including two at different tax rates, rather than using the demo data.
- Raise a bill with both rates on it and check the tax is computed per line, not once on the total.
- Print it on your own printer, on the paper or roll you actually use.
- Raise a second bill and confirm the number advanced by itself.
- Cancel one and check the number was not handed back for reuse.
- Add a customer with a GSTIN and confirm an inter-state supply switches to IGST without being asked.
- Export everything you just entered, and open the file. If you cannot, stop there.
The second person, and what changes
Almost every billing system that fails does so at the point a second person starts billing, and the failure is always the same shape. Two people, two copies, two numbering series, and a month that cannot be reconciled.
What a shared system changes is not convenience but authority. There is one record, one series of numbers issued centrally, and an audit of who raised what. None of that is possible when the record is a file that can be copied.
It changes what you can delegate, too. Billing can be handed to staff while the reports stay yours, because seeing a day's total and editing a day's invoices are different permissions. With a shared file they are the same permission.
If you are a single operator today, this is the thing to plan for rather than the thing to buy for. Moving a year of history is the expensive part, and it gets more expensive each month.
What a billing system cannot do for a trade
Worth saying plainly, because a page like this is usually written the other way round. Billing software issues documents, keeps records and reports. It does not run the trade-specific machinery around them.
It will not integrate with your weighing scale, your fuel dispensers, your kitchen display or your network provisioning. It does not hold clinical records or manage appointments. It does not do production planning, project costing or time capture. Where any of those is the actual problem, a billing system is not the answer to it and will not become one.
What it does do is the part every trade shares: a correct document, a numbering series that holds, tax computed rather than typed, a record of who owes what, and figures that a return can be built from. That is a narrow job done properly.
The sensible way to choose is to write down the three things that would make the software useless to you, then test those three first. Features are easy to compare and mostly not the deciding factor.
Reverse charge, exports and the supplies that behave differently
Not every supply is a straightforward taxable sale. Some notified supplies put the tax liability on the recipient rather than the supplier. Exports and supplies to an SEZ can be made under a bond or LUT without payment of tax, or with tax and a refund claimed afterwards. Composition dealers cannot charge tax at all and must say so on the bill.
Each of these changes what the invoice has to say — the reverse charge marking, the LUT reference, the "composition taxable person" declaration. They are not exotic cases; most businesses hit at least one.
The fields are on the invoice in Billixo whether or not you use them, so the day you need one you are not looking for a workaround.
What a GST invoice legally has to carry
Rule 46 of the CGST Rules sets out what a tax invoice must show, and it is a longer list than most invoice templates carry. Getting one field wrong does not usually cost you anything the day you raise it — it costs your customer their input credit months later, which is a harder conversation.
The fields are:
- Your name, address and GSTIN
- A consecutive invoice number, unique within the financial year
- The date of issue
- The customer's name, address and GSTIN where they are registered
- Place of supply, and the state code, for inter-state supplies
- HSN or SAC against every line
- Description, quantity, unit, rate and taxable value per line
- Rate and amount of CGST, SGST/UTGST, IGST and cess, shown separately
- Whether tax is payable on reverse charge
- Signature or digital signature of the supplier or an authorised person
Billixo fills these in from the customer and product records rather than asking you to remember them, which is the only reliable way a busy counter gets them all right every time.
Bill scanning, in practice
The single largest time cost in most small businesses is not raising invoices — it is entering purchases. A photograph of a supplier bill goes in and a structured draft comes out: supplier, GSTIN, line items, rates, tax split and total.
You check it. That is the workflow, and it is deliberate: an extraction you did not read is a liability, not a saving. But checking a filled form takes fifteen seconds and typing one takes three minutes, and that difference compounds over a month of purchases.
Who it is built for
Small and mid-sized Indian businesses that are registered under GST and bill regularly. One person doing everything, or a counter with three people billing at once and an accountant who needs the month to close cleanly.
The design assumption throughout is that whoever raises the invoice is busy and is not a tax specialist. So the tax is computed rather than asked for, the compliance fields are populated rather than presented as questions, and the report the accountant wants is a download rather than a request.
Try it free — the free plan needs no card and does not expire.
Free, and what it costs you instead
Free software usually costs you something that is not money: your data held hostage, an export that does not work, ads inside your invoice, or a "free" tier so narrow it is a demo with a login screen.
The line here is drawn differently. Export works on the free plan — CSV, Excel and JSON — because data you cannot get out is not data you own. The invoice is a real compliant invoice, not a sample. The limits are on volume and on the conveniences, not on whether the thing works.
Start free now. If it does not suit you, take your data with you.
Reliability, backups and getting your data out
Cloud billing software is only as good as its worst day. Two things matter more than any feature list: that your data is backed up somewhere you can reach, and that you can export it in a format something else can read.
Exports here are CSV, Excel and JSON, on every plan including the free one, covering customers, products, invoices and payments. That is the honest test of whether software respects you — not what it promises, but what it lets you take when you leave.
Frequently asked questions
Will it file my GST returns?
It prepares the figures and exports GSTR-1 and GSTR-3B data on the paid plans. Filing happens on the government portal, and nothing here submits a return on your behalf or claims to.
Is there a free plan?
Yes. The Free plan is ₹0, needs no card and has no expiry date. It carries volume limits, a single login and a small watermark on the PDF, and the invoice it issues is a complete GST tax invoice. Every new account also gets the full paid feature set for its first fortnight so you can see the ceiling before deciding.
Will it work for my trade specifically?
Test it rather than take anyone's word. Load ten of your own items including two at different tax rates, raise a real bill, print it on your own printer and time yourself. Half an hour on the free plan tells you more than any feature list, including this one.
Do I need to install anything?
No. It runs in a browser, on a laptop, desktop or phone, so there is nothing to install, nothing to update and nothing tied to one machine. If the office computer dies, you sign in from another one and everything is there.
Are the invoices valid for GST?
Yes. Every invoice carries the fields Rule 46 requires — GSTIN, HSN/SAC on each line, place of supply, the correct CGST/SGST or IGST split, and a consecutive invoice series that restarts each financial year.
Start free, decide later
You do not have to choose a plan to begin. Start on Free, use it for as long as it suits you, and upgrade only when a limit actually gets in your way — never automatically, and never because a countdown ran out.
