Retail software that never stops billing

T7 Solution builds hybrid POS, inventory, GST billing, barcode systems, loyalty programs, WhatsApp marketing and e-commerce integrations — for single-store retailers, multi-branch chains and D2C brands.

Overview

Retail runs on margin points and speed at the counter. Every stockout, dead SKU and slow bill compounds. We build offline-first POS that never stops billing, real-time multi-branch inventory sync and loyalty that lives inside WhatsApp — not a card in someone's wallet.

Our retail stack ships GST-ready invoicing, e-invoicing, barcode workflows, cashier UX built for touch, and clean integrations with your accounting, e-commerce and marketplace channels.

Every deployment is tuned for Indian and Middle East realities: intermittent internet, multi-lingual staff, GST/VAT compliance and WhatsApp-driven customers.

What we build

Hybrid POS (offline-first)
