Dexova POS — Cashier & Reconciliation

Context

Dexova POS serves two personas: cashiers work in the cashier app (dex-pos); owners and managers run products, outlets, and reports from the admin dashboard (dex-fe). The core design goal: a cashier should be productive without lengthy training, while every rupiah stays traceable.

Transaction flow

• Product search + barcode scanning (html5-qrcode), with variants and add-ons.
• Tiered pricing per product: retail, wholesale, member.
• Hold & resume carts — a cashier can serve the next customer without losing a pending transaction.
• Customer selection for member pricing and history.
• Large catalogs stay smooth — the product list is virtualized (TanStack Virtual), and one codebase serves a tablet split-panel layout and a phone slide-up cart.

Payments

Every payment method common in Indonesian retail, in one checkout flow:

• Cash with change calculation.
• Midtrans QRIS — static (one QR for all transactions) and dynamic (per-transaction QR with a locked amount).
• Bank transfer and EDC.
• Split payment — one transaction paid with a combination of methods.
• Promo codes and discounts governed from the admin dashboard.

Shifts & cash reconciliation

The part that separates a serious POS from a sales recorder — per-shift cash accountability:

• Open a shift with opening cash; a single-active-shift rule prevents transactions without an accountable owner.
• Close a shift with reconciliation: the system compares expected cash against the physical cash the cashier counts.
• Shift summaries and daily cash reconciliation are available as owner reports.

Void & returns

• Void for unfinished transactions; partial or full returns for paid ones.
• Stock restores automatically on returns — real-time WebSocket sync with the Inventory module, no manual step.
• Void/return access is role-scoped (cashier vs manager), revocable from the dashboard.

Hardware & reports

• Thermal receipts over Web Bluetooth — a hand-written ESC/POS driver (not an off-the-shelf library), with reprint.
• Owner reports: best sellers, dead stock, margins, taxes, shift summaries — PDF/Excel export.
• Multi-outlet with per-outlet staff placement.

Outcome

• Non-technical cashiers are productive immediately; the transaction flow is built for rush hours.
• Cash is accountable per shift — differences surface the same day.
• Sales, returns, and stock stay consistent because POS and Inventory share one source of data.
