A POS that keeps selling with no internet

RushFlow offline POS means a dropped connection never stops the till. The dedicated Android/Sunmi cashier app keeps ringing up sales, taking payment and printing receipts while the internet is down, holding each sale safely on the device. The moment the connection returns it syncs on its own — every sale posts to stock and accounting with no re-keying and nothing lost. It is built into the POS app, so there is no separate offline mode to buy or switch on.

The counter never freezes

A cloud-only till stalls the instant the Wi-Fi flickers — exactly when a queue is forming. RushFlow keeps selling locally on the device, so cashiers carry on and customers never wait on your connection.

  • Ring up sales and take payment with no internet
  • Receipts keep printing throughout (built-in, Bluetooth, USB, network)
  • Barcode scanning and product search work offline
  • Sales are stored safely on the device until they sync

Automatic sync — nothing to remember

When the connection comes back the app uploads every offline sale by itself. There is no manual export, no “sync now” chore, and no risk of a forgotten batch.

  • Offline sales upload automatically on reconnect
  • Stock deducts and accounting posts once synced
  • Order of sales and totals are preserved exactly
  • Multiple devices reconcile to one company view

The books still balance

Because POS, inventory and accounting are one system, an offline sale lands in the ledger the same way an online one does once it syncs — revenue, tax and cost of goods sold all posted correctly, per branch.

  • Revenue, tax and COGS posted per synced sale
  • Per-branch stock stays accurate
  • Customer dues and payments captured offline too
  • No month-end reconciliation of a separate offline till

Frequently asked questions

Does RushFlow POS work without internet?+
Yes. The RushFlow Android/Sunmi POS app keeps ringing up sales, taking payment and printing receipts with no internet, holds each sale on the device, and syncs automatically once the connection returns.
What happens to offline sales when the internet comes back?+
They upload automatically. Each offline sale then posts to stock and accounting exactly as an online sale would — revenue, tax and cost of goods sold per branch — with no manual export.
Do I need to switch on a special offline mode?+
No. Offline selling is built into the RushFlow POS app. It carries on through a weak or dropped connection on its own and syncs when it can.
Can I still print receipts while offline?+
Yes. Receipt and label printing works throughout an outage on built-in, Bluetooth, USB and network printers.
Which devices support offline POS?+
Android phones and tablets and Sunmi handhelds and terminals running the dedicated RushFlow POS app.
