Engineering Olio: Building a Full-Stack Restaurant POS and Operations Suite

Hospitality operations demand software that never drops a ticket, handles erratic network conditions, and accommodates mixed local payment methods.

Olio The Cafe & Resto was built to bridge customer-facing reservations with high-speed point-of-sale (POS) workflows under a unified codebase.

Core Engineering Decisions

• Real-Time Firestore Sync: Order state updates instantly across the cashier terminal, kitchen display, and customer status pages using active snapshot listeners with offline fallback.
• Multi-Method Split Payments: Full native support for cash, bKash, Nagad, and debit or credit cards within a single order flow, alongside automated dues (baki) tracking ledger entries.
• Automated WhatsApp and PDF Receipts: Built-in client-side receipt generators produce formatted thermal print layouts and send instant receipt summaries via WhatsApp links.
• Role-Based Operational Security: Distinct permission boundaries for waitstaff, kitchen managers, and executive administrators prevent unauthorized adjustments to past sales ledgers.
