Most Tamil Nadu pharmacists compare software on five things: does it log each Schedule H1 sale at billing with the particulars D&C Rules Rule 65 asks for, kept for three years, does it block expired stock from being sold rather than just warn about it, does it handle the current GST slabs correctly — 5% on most medicines after the September 2025 GST Council revision, with some items at 0% or 18% — rather than one hardcoded rate, does billing keep working when the internet drops, and is the pricing published or does it need a sales call to find out.
Marg ERP, the desktop system many Tamil Nadu pharmacies already run, lists its licence from ₹5,550 (Nano) or ₹10,300 (Basic) plus 18% GST, with a yearly renewal quoted by Marg's dealers (margcompusoft.com, as of September 2026). Nesayo's billing is free forever with no invoice limit; paid plans add voice billing and photo prescription scanning from ₹249/month, and all five AI agents at ₹549/month (as of October 2026). See the full breakdown on the Nesayo vs Marg ERP comparison or run your own numbers with the margin calculator.
Under D&C Rules Rule 65, a Schedule H1 supply is recorded with the prescriber's name and address, the patient's name, the drug and the quantity, kept for three years and open to inspection by your state's Drugs Control Department. Nesayo logs each Schedule H1 sale at billing (patient, prescriber, medicine, batch, quantity) and the pharmacist adds the prescriber's address, and expired stock is hard-blocked at the counter rather than flagged — Section 27 of the Drugs and Cosmetics Act makes selling either an offence, not a formality. See the exact columns in the Schedule H1 register format guide.
If the billing page is already open, new bills can be queued after a connection drop and synced when the connection returns. Opening the page, live catalogue search and editing saved bills need a connection. Review synced bills before relying on them. Explore the live demo or the free tools.

Yes. Export your stock from Marg ERP as CSV or Excel and upload it to Nesayo in two clicks. Batch numbers, expiry dates (MM/YY, MMM-YY or DD.MM.YYYY), MRP and HSN codes are all auto-detected.
Voice billing is in beta on the paid plans (from ₹249/month as of October 2026). It combines speech recognition with AI to handle natural spoken Tamil — including everyday Madras Bashai phrasing common in Chennai — mixed with English medicine names. It also works for Hindi, Telugu, Kannada, Marathi, Bengali, Gujarati, Punjabi, Urdu and English. Every spoken line lands on a draft you confirm before anything is billed.
Schedule H1 sales are logged automatically at billing: date, medicine, batch, quantity and bill number, with the patient and prescriber names entered on the bill. Nesayo does not record the prescriber's address yet, so the pharmacist adds it to complete the Rule 65(3)(h) register. Tamil Nadu's Directorate of Drugs Control Administration inspects against Rule 65, which applies across India. GST is calculated at 5% by default following the September 2025 GST Council rate change, the same as everywhere else in India. If your drug licence needs a state-specific format printed, enter it once in settings and it appears on every invoice.
