Can't open a shift or log in to the register

Staff can't get the POS ready to trade — login fails, or a shift won't open.

Symptoms

• The register won't accept a login or PIN.
• You can't open a shift, or the app is stuck on a lock screen.
• Sales are blocked until a shift is open.

Likely causes

1. No register account / register not set up for this device.
2. Wrong credentials or PIN, or the staff member lacks access to this outlet.
3. A shift is already open on another device, or the previous shift wasn't closed.
4. App lock is on and needs the unlock code.
5. Connectivity — login is verified online.

How to fix

1. Confirm the device has an outlet register set up and that the user has access to that outlet. See Outlet & Register setup.
2. Re-enter credentials carefully; if forgotten, an admin can reset the user or PIN.
3. Open a shift before selling. If the system says one is already open, close the previous shift (possibly on another device) first, then open a fresh one.
4. If you're on the lock screen, enter the unlock code; an admin can reset it in POS/merchant settings if it's lost.
5. Check the tablet's internet connection — first login and shift actions need to reach the server.

Still stuck?

Note the register/outlet, the user trying to log in, and the exact message, then contact support. Include the app version (in Settings) for login problems.
