EXPLORE →Billing & GST compliance
Counter-speed billing that stays GST-perfect — from barcode scan to WhatsApp receipt.
GST billing & invoicing
Generate GST-compliant invoices in seconds with automatic tax calculation for every slab. GSTN integration keeps filings aligned with what you actually sold.
Customizable invoice templates
Your logo, your terms, your format — thermal receipt or A4, in the language your customers read.
Barcode POS
Scan-and-bill checkout built for rush hour. Auto-generated barcodes for unlabelled items, weighing-scale support for grocery.
Inventory & purchase
Stock that counts itself — real-time inventory, auto item masters and phone-based audits.
Real-time inventory tracking
Every sale, return and purchase updates stock instantly — across all counters and all stores.
Purchase management
Purchase orders, supplier records and margin visibility per item, so reordering is data-driven, not guesswork.
Stock audit via Android app
Walk the aisles with a phone instead of a clipboard. Scan, count and reconcile stock in hours, not days.
Automated item master creation
New products enter your catalog automatically — no more late-night data entry to add stock.
Customers & growth
Schemes, coupons, loyalty points and WhatsApp offers that lift retention up to 50%.
Loyalty points & membership cards
Reward repeat buyers with points and memberships that keep them coming back to your counter, not a marketplace.
Coupons & discount schemes
Festival sales, buy-one-get-one, category discounts — configured in minutes, applied automatically at billing.
Inactive customer re-engagement
er4u automatically identifies customers who haven't purchased in 60+ days so you can win them back with a targeted offer.
WhatsApp & SMS alerts
Send bills, offers and payment reminders on WhatsApp and SMS — the channels Indian customers actually open.
Scale & control
Head office, branches, franchisees and warehouses — one dashboard, live stock everywhere.
Multi-store management
Central control of pricing, stock transfer and reporting across every branch, with per-store P&L visibility.
User permissions
Unlimited users in every plan, with role-based permissions so staff see only what they need.
Mobile app (Android & iOS)
Sales, stock and reports on your phone or tablet — run the shop even when you're not in the shop.
Cloud & offline versions
Choose cloud for anywhere-access or offline for zero internet dependency. Windows, Mac and Linux supported (min 4GB RAM).
