Android App

Keep the phone and the web in sync

Download, Auto-Sync Interval, Validate Data, and what to do when the two disagree.

Menu item	What it does
Download (Update From Web)	Pulls the current picture down from the server — items, customers, prices. Use after work was done on the web or another device.
Auto-Sync Interval (Settings)	How often the app syncs itself. Shorter keeps devices closer together; longer saves battery and data.
Validate Data (Settings)	Checks the phone’s own records for problems. Run it if figures look wrong before assuming the server is at fault.

They will occasionally disagree, and it is almost always a sync gap rather than a fault.

Run Download to pull the web’s current version onto the phone.
Confirm the ✓ Synced badge so anything entered on the phone has gone up.
Only if the gap survives both steps is it worth raising with support.

A sales point is a till. On the web you pick one at each sign-in; on Android the device is bound to one, which is why a phone can keep selling with no network — it already knows which till it is. Two devices must not share one till.

In practice: sell on the phone, administer on the web. The phone is better at the counter and on a delivery round; the website is better for bulk data, the storefront and anything involving a spreadsheet.

If something looks wrong

The badge isn’t green — get onto Wi-Fi and let it sync before doing anything else.
The phone shows different figures from the website — run Download, then confirm the badge.
Figures look wrong and sync is fine — Settings → Validate Data.
