Most Tamil Nadu pharmacists compare software on five things: does it auto-maintain the Schedule H1 register per D&C Rules Rule 65 (three-year retention, ideally tamper-evident), 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, 12% or 18% on others — 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, charges roughly ₹4,000 a year (₹333/month) for billing alone plus an annual AMC — about ₹12,000 over three years before any AI features. Nesayo's billing is free forever with no invoice limit; the optional AI Employee (voice billing, photo prescription scanning, five autonomous agents) is ₹999/month. 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, every Schedule H1 sale needs the prescriber's name, the patient's details, the batch and the quantity recorded and kept for three years, open to inspection by your state's Drugs Control Department. Nesayo writes that entry automatically on every qualifying sale instead of a paper register, 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.
Nesayo bills offline by design — it caches locally as a Progressive Web App, so a bill can be completed and printed even when the connection drops, then syncs automatically once it's back. That matters most for counters away from the city core, where a dead router isn't rare. Try it on the live demo or see every free tool on the tools page.

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.
Yes. Nesayo combines AI with our speech engine speech recognition, trained on 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.
Schedule H/H1 drug registers are auto-maintained for every sale (3-year retention per D&C Rules Rule 65) — ready whenever Tamil Nadu's Directorate of Drugs Control Administration inspects your store. 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.
Pharmacy billing on Nesayo is free forever — unlimited bills, GST, the medicine database, Schedule H/H1, FEFO batch and expiry tracking, and Marg import, all at ₹0. Marg ERP, by contrast, charges roughly ₹4,000/year (~₹333/month) just for billing. The AI Employee — voice billing, photo prescription scanning and the 5 AI agents — is an optional ₹999/month add-on (₹9,990/year) that typically pays for itself in week one by preventing ₹15,000-30,000/month in expiry, missed refills and stuck payments. The first 100 pharmacies lock the AI Employee at ₹299/month for life.
2-minute signup. No credit card. Free billing — AI Employee ₹999/month.
