Multi-Store Retail POS & Odoo Enterprise Sync

1. Project Overview

2. Business Challenge

Operating multiple physical retail branches with poor internet connectivity led to transaction dropouts, delayed daily closing ledger reconciliations, and mismatched branch stock levels.

3. Existing Environment

• Legacy offline desktop POS terminals with manual night-end CSV data uploads.
• No real-time inventory visibility across store branches.
• Inability to issue or redeem store gift cards and loyalty points cross-branch.

4. Key Requirements

• 100% offline-resilient POS register operation during internet outages.
• Instant background sync of sales orders and inventory decrements upon reconnection.
• Unified omnichannel customer profile and loyalty reward balance tracking across all branches.

5. Odoo Architecture & Core Modules

Deployed Odoo POS Service Workers coupled with IndexedDB local browser storage for zero-downtime offline transactions.

6. Custom Development

• Custom offline transaction queue conflict-resolution engine for simultaneous item purchases.
• Custom hardware integration module for Bluetooth receipt printers and cash drawer triggers.

7. Third-Party Integrations

• Integrated Payment Terminal (Verifone / Ingenico) API for automated card processing.
• WhatsApp API integration for paperless digital receipt delivery.

8. Implementation & Testing

Executed network kill-switch simulation testing across 25+ POS terminals, stress-testing offline transaction persistence and automatic reconciliation upon network restore.

9. Measurable Operational Results

10. Client Testimonial

"Gradiant's Odoo POS integration ensured our stores never stop selling during internet outages. The automatic inventory reconciliation gives our management complete visibility."
