Windows POS · Offline First
Windows Desktop POS That Keeps Selling — With or Without Internet
The Sum Cloud POS desktop app runs natively on Windows 10 and 11. Touch-optimized checkout, thermal printing, and delivery order management — fully offline when your connection drops, cloud-synced when it returns.
Features
A complete Windows POS — no compromises
True Offline Billing
The desktop app stores your entire product catalog and customer list locally using SQLite. Internet or not — billing never stops. All offline sales sync automatically when connectivity returns.
Touch-Screen Optimized
Large buttons, swipe gestures, and a clean touch-first layout make the checkout flow fast on any touch display. Works equally well with a mouse and keyboard at a standard counter.
Thermal & Receipt Printing
Connect any USB or network thermal printer. The custom receipt template builder lets you add your logo, change fonts, and rearrange the receipt layout — no coding required.
Cloud Sync
Products, customers, and promotions sync down from the cloud. Every sale syncs up — so your web dashboard always shows live data across all branches and terminals.
Delivery Order Management
Built-in delivery flow: search customers by phone, assign delivery charges per customer, track delivery orders, and sync payment status — fully offline-capable and cloud-synced.
Online Orders (SumBite)
An integrated online orders panel shows incoming SumBite orders at the counter. Accept, set ETA, reject, and toggle your restaurant live/offline — all from the desktop app.
Customer Ledger & Credit
Record customer credit sales, receive payments offline, view full transaction ledger, and print payment receipts — all without internet, synced when online.
Discounts & Customer Rates
Apply rule-based discounts, promotional codes, or per-customer static discount rates. Discount amounts are automatically deducted at checkout when the customer is selected.
FBR & Tax Ready
Tax rules, VAT rates, and FBR invoice formatting are all configurable. Every receipt prints with the correct tax breakdown — keeping you compliant without extra work.
Offline-First Architecture
Why offline matters for POS
Internet outages during peak hours cost businesses real money. The Sum Cloud POS desktop app is built offline-first — the cloud is the system of record, but the counter never waits for a server response.
- Full product catalog stored locally with SQLite
- Pending sales queued and batch-synced on reconnect
- Customer data, credit balances, and discount rules all local
- Delivery orders taken and stored offline, synced later
- LAN bridge keeps kitchen display working without cloud
