Offline Continuity Engine

Keep ringing sales when Wi-Fi drops. Zero lost revenue.

Most cloud POS systems freeze or show spinning loaders when the internet disconnects. Bayon POS uses a local encrypted storage engine on each counter screen.

Instant Local Transaction Commit: Sales and drawer balance updates write to local memory first in <50ms.

Automatic Background Sync: Queued sales sync back to the cloud automatically once internet reconnects.

Zero Interruption: Receipt printing and cash drawer kick continue functioning seamlessly offline.

Offline Architecture Flow

1. Local Device CacheActive

Product catalog and pricing stored locally on tablet/PC.

2. Encrypted Transaction QueueIdempotent

Offline cash sales are fingerprinted to prevent duplicate posting.

3. Reconnect & Cloud ReconciliationAutomatic

Server audits offline sequence numbers and updates dashboard reports.

Dual-Currency Settlement

Accurate USD & KHR cash handling. Eliminate mental math errors.

Cambodian retail operates in two currencies simultaneously. Bayon POS automates currency conversion on every transaction so cashiers never give wrong change.

Live Dual-Total Display: Every bill shows total due in USD and KHR side by side.

Mixed Tender Acceptance: Accept $10 USD + 10,000 Riel for a single sale with instant change derivation.

Configurable FX Rate: Set your store exchange rate (e.g. 4,100 KHR) from the dashboard.

Dual-Currency Change Derivation Example

Total Order Amount:$4.25 (៛17,425)

Cash Received from Customer:$10.00 USD Bill

Change Due to Customer:

$5.75 USDor ៛23,575 KHR

Shift Z-Reports & Cash Control

Full drawer reconciliation. Know exactly what happened every shift.

Prevent cash discrepancies with structured shift openings, cash movement logs, and blind drawer counts at close.

Opening Floats: Record opening USD and KHR float balances before sales begin.

Paid-In / Paid-Out Tracking: Track petty cash expenses or cash drops during the day.

Blind Shift Z-Report: Cashiers count cash before seeing expected totals, preventing manipulation.
