Data from every counter flows straight into Acumatica
For chains with dozens or hundreds of locations, the value of a POS lies not in the cashier screen but in the quality of data reaching head office. S4 POS is pre-integrated with Acumatica and standardizes catalog, pricing and shift processes across the chain; chains on another POS can still connect through S4 Integration Platform without replacing it.
The counter sales lifecycle on S4 POS
From item catalog to shift close, running smoothly and in sync with Acumatica.
Catalog & pricing
Central item management, barcodes, lots and expiry dates, store-specific prices.
Store setup
A dedicated warehouse per store, real-time stock, role-based permissions.
Billing counter
Barcode scanning, automatic promotions, loyalty points, touch UI on POS, tablet and mobile.
Shift open / close
Record collections during the shift; at close, consolidate transactions into one invoice while keeping every receipt.
Functional description based on the S4 eSuite Point of Sale page.
S4 POS screens at the counter
The three cashier screens used most during a shift: sales, table map and payment.
Fast ordering on a touch screen
Cashiers pick items by category (coffee, juice, toppings) or search by name or code. Orders are tied to a table, with notes per item and member discounts applied directly on the order.
- Notes per item: iced, hot, less sugar
- Member card discounts with automatic totals
- Save, send to kitchen and pay from one screen
- Shows the open shift, cashier and sync status
Tables managed by area
The table map shows which tables are free, being served or waiting for payment, with the amount and time seated. Shift managers see the store status at a glance.
- Areas A and B, seats per table
- Status colors: free, serving, awaiting payment
- Move or merge tables
- Start a takeaway order from the map
Cash and VietQR bank transfer
The payment screen shows order lines, discount and amount due. For cash, the cashier taps a suggested note or types the amount and the change is calculated automatically; customers can also pay by VietQR transfer.
- Suggested notes and an “Exact amount” button
- Automatic change calculation
- VietQR bank transfer
- Each receipt has a store-based document number for reconciliation
