PharmaStok's core idea is genuinely useful — send a supplier invoice photo over WhatsApp and let AI update your stock. Its free plan stops at 10 invoice uploads a month with no billing at all. Here's a feature-by-feature look at both, current as of September 2026.
No download to install and no demo call to book: you can drive Nesayo right now — the real product on a sample pharmacy, no signup.

The idea behind PharmaStok is a real, narrow, useful one: a large share of a pharmacy's stock data-entry time goes into typing out supplier invoices line by line after every delivery. Pointing a phone camera at that invoice and sending it over WhatsApp, then getting medicine name, batch, expiry, quantity, MRP, purchase rate and GST extracted automatically, removes a genuinely tedious step — and doing it over WhatsApp rather than a separate app login is a sensible choice for how Indian pharmacists already work.
Its published feature list also covers the basics well: retail GST billing with a CGST/SGST breakdown, batch and expiry tracking with 30-day expiry alerts, reorder-level alerts, and sales-vs-purchase analytics for fast movers and dead stock. For a pharmacy whose main pain point is the purchase-invoice bottleneck specifically, that's a tightly scoped, understandable product.
This is the most important practical difference for a pharmacy comparing the two on cost. PharmaStok's free tier, per pharmastok.com, is capped at 10 invoice uploads a month and does not include billing or WhatsApp features at all — so a pharmacy that wants to actually bill customers on PharmaStok needs the Starter plan at ₹499/month + 18% GST (capped at 50 invoices/month) or the Pro plan at ₹999/month + 18% GST for unlimited invoices, both figures as of September 2026.
Nesayo's free plan is unlimited GST billing, on any device, with no card and no bill cap, for as long as a pharmacy wants to stay on it. The AI layer — voice billing, photo prescription scan, and the five autonomous agents — is free for a new pharmacy's first month (on the Full plan), then Essential at ₹249/month or the Full plan at ₹549/month, as of October 2026.
We looked for a Schedule H1 dispensing register, FEFO enforcement at the point of sale, voice billing, drug interaction checks, and a named set of autonomous agents in PharmaStok's public pages and did not find any of them mentioned. That is different from confirming they don't exist — a feature can be real and simply not listed on a marketing page — so pharmacies for whom Schedule H1 register-keeping or FEFO enforcement is the deciding factor should ask PharmaStok directly and compare the answer against what they need under the Drugs and Cosmetics Rules.
PharmaStok also lists a 14-day free trial on its Pro plan and claims service across pharmacies in 19 states, per pharmastok.com — figures worth confirming directly with them if they matter to your decision, since we could not independently verify every detail beyond what's published on their own site.
Partially. PharmaStok's free plan allows up to 10 invoice uploads a month with no card required, but it does not include billing or WhatsApp features at all, per pharmastok.com as of September 2026. To bill customers on PharmaStok you need the Starter plan (₹499/month + 18% GST, up to 50 invoices/month) or the Pro plan (₹999/month + 18% GST, unlimited invoices). Nesayo's billing plan is unlimited and free forever, with no invoice cap.
Per pharmastok.com, up to 10 supplier-invoice uploads a month, with no billing and no WhatsApp integration. It's aimed at trying the invoice-reading feature, not at running a pharmacy's day-to-day billing.
We could not find one documented in PharmaStok's public pages as of September 2026. That doesn't confirm it's absent — only that it isn't listed — so if Schedule H1 register-keeping matters to your pharmacy, ask PharmaStok directly. Nesayo logs Schedule H1 sales 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.
We found no mention of voice billing in PharmaStok's public sources as of September 2026 — its input modality, per pharmastok.com, is WhatsApp text, photo and PDF upload. Nesayo supports voice billing in English, Hindi and Hinglish (voice beta).
For billing alone: Nesayo is ₹0 with no invoice cap, forever. PharmaStok's billing starts at ₹499/month + 18% GST once you're past the free tier's 10 invoice uploads (which carries no billing at all). On the AI side, Nesayo's Full plan is free for a new pharmacy's first month, then ₹249/month (Essential) or ₹549/month (Full) as of October 2026; PharmaStok's Pro plan (unlimited invoices, full analytics) is ₹999/month + 18% GST, per pharmastok.com.
Both read a supplier invoice photo or PDF and extract line items into stock automatically — it's PharmaStok's central, most-marketed feature, and it's part of Nesayo's AI stock-import as well. We haven't run a side-by-side accuracy test between the two products, so we won't claim one reads invoices more accurately than the other.
Yes. Export your stock and customer list as CSV or an invoice/statement PDF and Nesayo's AI import will read it in — the same photo/PDF-reading approach PharmaStok uses for supplier invoices, applied to your existing records.
PharmaStok states it serves pharmacies across 19 states and supports major Indian distributor invoice formats, per pharmastok.com as of September 2026 — we'd suggest confirming coverage for your specific state directly with them before signing up. Nesayo does not make a state-count claim; the product works anywhere in India with GST billing and the medicine catalogue built in.
If automating supplier-invoice-to-stock entry is your single biggest pain point and you're comfortable paying ₹499–999/month + 18% GST once you need billing too, PharmaStok's WhatsApp-first workflow is built specifically for that. If you also want free unlimited billing, Schedule H1 sales logged at billing, FEFO, voice billing and a built-in 2,54,034-medicine catalogue, Nesayo covers the invoice-reading piece as well as the rest of the counter.
Check any medicine's Schedule (H1/H/X), look up its HSN code and GST rate, or decode a printed expiry date — nesayo.com/tools.
Bill unlimited GST invoices free forever. Add voice billing and prescription scanning from ₹249/month, or all five AI agents at ₹549/month, as of October 2026.
