Multi-Outlet Restaurant POS: Eliminating Saturday Billing Halts & Unifying Central Inventory

The Problem

A regional casual dining chain operating 4 outlets across Sector 26 Chandigarh, Elante Mall, and Phase 3B2 Mohali was using a legacy cloud POS. During peak weekend dinner rushes, internet fluctuations caused the POS to freeze completely, resulting in 15-minute billing delays, frustrated patrons, and lost tables. Additionally, central inventory had to be manually reconciled across multiple spreadsheets every night.

The Engineered Solution

Swarn Solutions built a bespoke, offline-first POS billing application powered by local SQLite databases and ESC/POS thermal printing. Waiter Android tablets submit orders directly to kitchen thermal printers over the local Wi-Fi without needing external internet. An automated background sync engine reconciles transactions with the central MySQL cloud server every 60 seconds whenever connectivity is active.

  • SQLite (Local Offline Storage)
  • Node.js / Express API
  • MySQL Cloud Sync
  • ESC/POS Raw Thermal Drivers

B2B Sales CRM: WhatsApp Automation & Instant PDF Quoting for Precision Auto Components

The Problem

A precision auto components manufacturer in Mohali Sector 74 managed inbound inquiries through fragmented personal WhatsApp messages and physical registers. Sales executives took 24 to 48 hours to prepare custom GST quotations, leading to high prospect drop-off rates and zero accountability over sales pipeline status.

The Engineered Solution

We engineered a tailored web-based CRM integrated directly with the official WhatsApp Business Cloud API. Inbound leads from Indiamart and the website are automatically captured, assigned to reps, and acknowledged via automated WhatsApp messages in seconds. Reps can generate dynamic, GST-compliant PDF quotes with tiered volume pricing in under 60 seconds directly from their smartphones.

Marketplace Return Reconciliation Engine: Recovering Lost Revenue Across Meesho & Amazon

The Problem

A fast-scaling Delhi-NCR apparel brand shipping 15,000+ monthly orders across Meesho, Flipkart, and Amazon was bleeding over ₹2.5 Lakh per month in courier weight discrepancies, missing returns (RTO claims not delivered back by couriers), and wrong payment settlements that their 4-person accounting team had no time to manually reconcile.

The Engineered Solution

Swarn Solutions built a custom marketplace reconciliation portal. The system automatically ingests marketplace CSV settlement reports and courier tracking manifests, cross-references return tracking numbers against warehouse barcode scan logs, and flags disputed weight charges and unreturned items with auto-formatted claim tickets ready for marketplace submission.

The Problem

A multi-specialty diagnostic and surgical clinic network in Chandigarh received over 350 phone calls per day for routine appointment scheduling, doctor availability inquiries, and lab report follow-ups.

The Engineered Solution

We deployed a secure WhatsApp conversational AI agent built on a private retrieval-augmented generation (RAG) architecture. Patients can check doctor OPD timings in English and Hinglish, book real-time appointment slots with calendar synchronization, and receive encrypted one-time download links for pathology lab reports directly within WhatsApp.
