Built for pharmacies in India
The problem
Why pharmacies are leaving legacy ERP
Marg, Vyapar, and the desktop incumbents were built for a different decade. Today's pharmacy owner runs WhatsApp orders, multi-branch stock, expiring schedules, and CA deadlines — and the software has not kept up.
Offline-only desktop
One PC, one stock-master. Owner can't see today's sales from the second branch or from home.
Schemes calculated by hand
"10+1, secondary scheme, billing-period bonus" — staff get them wrong, distributors over-claim.
No mobile, no WhatsApp
MR runs on paper, van delivery on memory, B2B orders typed manually from WhatsApp screenshots.
Compliance after-the-fact
GST recon, e-way, e-invoice IRN, drug licence renewals — patched in years late, often by exporting to Excel.
PharmOS in 60 seconds
One system. Cloud, desktop, and mobile — with the same data.
React 19 web app, Tauri desktop with embedded Postgres for offline counters, and native MR + Van apps. Updates ship continuously, not on an annual CD.
Cloud-native
SaaS or self-host on your VPS. Daily encrypted Postgres backups to R2 or Contabo, retention 14 daily / 8 weekly / 12 monthly.
Mobile-first
MR field app and Van delivery app — offline outbox, 60-second sync, expo-location, photo POD upload.
WhatsApp-integrated
B2B parser turns free-text WhatsApp orders into bills. Auto-dunning sends overdue reminders at 0 / 7 / 15 days.
Compliance built-in
GSTR-1 / 3B JSON + CSV, e-way bill, e-invoice IRN, drug licence tracker, DPDP-aware data handling.
How PharmOS works
From WhatsApp message to live counter in 48 hours.
No long sales cycle, no per-seat licensing maze, no annual CD. Three steps from your first call to the first bill on PharmOS.

Everything in the box
The features Indian pharmacies actually use
Every feature below ships in v0.22 and is live on the demo today. Nothing on the roadmap is shown as if it were ready.
POS billing
Box / strip / loose unit picker, return mode with Marg-parity, held-bills side panel, credit-override single-shot tokens, GSTR-aware tax breakdown.
Inventory + multi-godown
SKU master with substitutes and combo children, batch-level stock with godown / rack / bin, near-expiry dashboard, dead-stock and reorder-suggestion reports.
Scheme engine v3
Five scheme kinds — percent, qty, value-break, billing-period, secondary scheme, plus scheme-on-scheme stack. Distributor rate-lists per partner.
Compliance suite
GSTR-1 / 3B JSON + CSV, e-way bill (NIC scaffold), IRN e-invoice, drug-licence tracker with 30 / 14 / 7 / 0-day expiry alerts, GST late-fee calculator.
Multi-branch sync
Cursor-paginated pull, transactional batched push (1000 rows). Per-entity policy: POS bills client-wins, stock moves server-wins, masters last-write-wins. Conflicts logged and reviewable.
WhatsApp B2B parser
Free-text orders parsed into qty + unit + SKU lines, ILIKE-matched against your master, one-click convert-to-bill. Distributors stop typing orders by hand.
Reports — 12 tabs
Z-report, ageing, near-expiry, daily sales target, customer purchase frequency, doctor commission, margins, dead-stock, sales-by-staff, GST late-fee, hourly, top SKUs, reorder suggestions.
Mobile MR + Van apps
Expo-built native apps. MR weekly plan, visits, samples, visual-aid library. Van route, deliver, collect, UPI helper, photo POD. Offline-first with conflict log.
Bank recon + Tally + dunning
HDFC / ICICI / SBI / Axis CSV auto-detect with match-engine, Tally Prime XML (vouchers + masters + cost-centres), 0 / 7 / 15-day overdue auto-dunning worker.
Built for every pharmacy
Whether you run one counter or a hundred — PharmOS fits.
Retail chemists, multi-store chains, hospital pharmacies and wholesale distributors all run on the same PharmOS stack — different plans, same data model.
Single-store retail pharmacy
Counter billing in 12 seconds, batch + expiry on every line, GSTR-1 + 3B export in two clicks, daily sales on the owner's phone.
Start with Lite
Multi-store pharmacy chain
Centralised SKU master, inter-branch stock transfer, consolidated chain reports, role-based access for branch managers vs HQ.
Multi-Branch tier
Wholesale + distribution
WhatsApp B2B order parser, distributor rate-lists, scheme engine (10+1, secondary, billing-period), MR + Van mobile apps for the field team.
Pro tier
Compliance & trust — built in, not bolted on
Honest comparison
PharmOS vs Marg ERP
Marg helped a generation of Indian pharmacies digitise — credit where it's due. But the product was built for offline desktop, and the gap is now structural. Here is the side-by-side.
| Capability | Marg ERP | PharmOS |
|---|---|---|
| Cloud-native | No (desktop install) | Yes (SaaS or self-host) |
| Mobile apps | No first-party MR / Van app | MR + Van apps, offline outbox |
| WhatsApp B2B ordering | Manual entry from screenshots | Free-text parser → bill |
| Multi-branch sync | Limited, sneakernet between PCs | Built-in, conflict-policy per entity |
| Modern UX | Legacy desktop chrome | React 19 web + mobile + Tauri desktop |
| Auto-dunning (overdue reminders) | No | 0 / 7 / 15-day worker |
| GST + e-way + IRN | Manual exports | Integrated, NIC GSP wired |
| Updates | Annual CD / patch | Continuous (12+ releases in 30 days) |
| Pricing model | Per-license + AMC | Subscription, no per-seat lock-in |
Pilot story
Ram Medico, Pune
Single-store retail pharmacy with seven counter staff and a partner-portal token issued to their main distributor. Migrated from a desktop ERP with 26 SKUs and 29 active batches across an opening-stock value of roughly ₹54,000.
“We tried PharmOS as a parallel run for two weeks. The owner now reads daily sales from his phone, the partner-portal saves us 30 minutes of order-typing every morning, and the FY-close screen finally made our CA happy.”
— Pilot tenant feedback, paraphrased. Full case study on request.

Annual plans. GST extra. Free migration from Marg / Vyapar / BUSY / Excel.

How is PharmOS different from Marg ERP?+
PharmOS is cloud-native (Marg is desktop-only), has first-party MR + Van mobile apps (Marg has none), parses WhatsApp B2B orders into bills automatically, and ships continuous updates. We import your Marg data in 48 hours so you don't lose history.
Will you help us migrate from Marg, Vyapar or Excel?+
Yes — free. We import your SKU master, opening stock, distributors, customers and party ledger in your first onboarding call. Most pharmacies are live within 48 hours.
Does PharmOS work offline?+
Yes. The desktop counter app uses embedded Postgres so billing keeps running through power and internet outages. The moment you are back online, every counter syncs to your tenant on our India-hosted cloud.
Is my pharmacy data safe and DPDP-compliant?+
Your operational data stays on your counter and inside your tenant on our India-hosted cloud. We follow DPDP Act 2023 norms — purpose-limited collection, encrypted backups, your right to export and delete. You own the data and can leave anytime.
Does PharmOS support GST e-invoicing (IRN) and e-way bills?+
Yes. GSTR-1 + 3B JSON and CSV exports, e-invoice IRN generation, e-way bill scaffold (NIC GSP wired), GST late-fee calculator, drug-licence expiry alerts at 30 / 14 / 7 / 0 days.
How much does pharmacy software cost?+
PharmOS Lite is ₹11,999 per year (single store, single counter). Pro is ₹24,999 per year (multi-user + WhatsApp + mobile apps). Multi-Branch is custom pricing. GST extra. No per-seat lock-in.
Can I try PharmOS before buying?+
Yes. Book a 15-minute demo on your real data — call or WhatsApp +91 95694 14011, or fill the demo form. We give you a clean “yes / not yet” by the end of the call.
Does PharmOS work for hospital pharmacies and wholesalers?+
Yes. Hospital pharmacies use our Multi-rate billing and Schedule H register; wholesalers use the WhatsApp B2B parser, distributor rate-lists, scheme engine and MR + Van apps.
