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.
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, drug-licence renewals, H1 registers — patched in years late, usually via Excel exports.
No mockups — real screens
Straight from the live product.
Every screenshot below is captured from the running demo tenant — the same one we walk you through on your call. Nothing staged in a design tool.
POS billing · Sales mode
The real POS — batch + expiry per line, F-key shortcuts, hold / recall, split payments.
Stock register
Batch-level stock register — expiry, MRP, quantity and value on every line.
Near-expiry dashboard
Near-expiry dashboard — value at risk by window, one-click supplier return note.
WhatsApp orders · Review
WhatsApp B2B parser — free-text retailer message, parsed and SKU-matched, one click from a bill.
Medicines master
SKU master — salt, pack, HSN, GST rate and H / H1 / OTC schedule built in.
Reports · GSTR-3B
GSTR-3B monthly summary — download JSON, review tax payable, file on the portal.
Apps for the field team
MR and Van apps — on their own phones, even without network.
Your medical rep plans doctor visits, checks in with GPS and drops samples from the MR app. Your delivery driver runs the day's route, collects payments and uploads proof-of-delivery from the Van app. Both are offline-first — every action queues locally and syncs the moment the network returns.
- MR — weekly plan, visits, GPS check-in, sample register
- Van — route stops, UPI / cash collection, photo POD
- Offline outbox with a 60-second sync cycle and conflict log
MR app — Today's Plan, real device.
Van app — Today's Route.

Pro tier
Honest comparison
PharmOS vs legacy desktop 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.
| Capability | Legacy desktop ERP | PharmOS |
|---|---|---|
| Cloud-native | No — desktop install | SaaS or self-host, offline counter included |
| 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 |
| Auto-dunning | No | 0 / 7 / 15-day WhatsApp reminders |
| GST filing | Manual exports | GSTR-1 / 3B JSON + CSV, 2B recon, late-fee calc |
| Updates | Annual CD / patch | Continuous, code-signed auto-updates |
| Modern UX | Legacy desktop chrome | React 19 web + mobile + Tauri desktop |
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 full opening stock.
“We tried PharmOS as a parallel run for two weeks. The owner now reads daily sales from his phone, and the FY-close screen finally made our CA happy.”

FAQ
Common questions from pharmacy owners.
How is PharmOS different from Marg ERP?+
PharmOS is cloud-native with an offline desktop counter (Marg is desktop-only), has first-party MR + Van mobile apps, 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.
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 the cloud.
Are GST e-invoices generated?+
GSTR-1 and 3B JSON + CSV exports and GSTR-2B reconciliation are live today — download, review, file on the portal. The e-invoice (IRN) and e-way scaffolds are wired for NIC GSP and switch on when your GSP credentials are added; billing never blocks on them.
Will you help us migrate from Marg, Vyapar or Excel?+
Yes — free. Built-in import wizards bring in your SKU master, opening stock, distributors, customers and party ledger in your first onboarding call. Most pharmacies are live within 48 hours.
Is my pharmacy data safe?+
Your operational data stays on your counter and inside your tenant. DPDP-aware handling — purpose-limited collection, encrypted backups, your right to export and delete. You own the data and can leave anytime.
Can I sell PharmOS under my own brand?+
Yes — the white-label partner program gives you branded desktop builds with your own update channel, a self-service partner panel, and wholesale licensing. Contact us for the partner rate card.
