Why are there no Cash in or End of day buttons?

They need Cash drawer management at POS, which is off by default. Switch it on in Settings > Features.

Why can my cashiers not see the expected cash?

Blind drawer close is on in Settings > Team & roles. Cashiers count first and see the totals after closing.

No. The POS reminds you that No shift is open, but you can still sell. Cash taken outside a shift is not counted in any drawer.

A cash shift tracks the money in your drawer from opening float to closing count, so you know at once if the cash is short or over.

On the POS, tap the shift button in the status bar. It reads No shift open when no shift is running.
In Cash shift, count the notes and coins in the drawer, type the total in Opening float and press Open shift.
Sell as normal. Cash sales add to Expected in drawer; card and QR sales show under Cashless total.
At the end of the shift, open the shift button again and count all the cash in the drawer, including the float.
Type the total in Counted drawer total (including float). The sheet shows the Variance.
If the count does not match, write why in Variance note. Press Close shift.

Switch on Cash drawer management at POS in Settings > Features to add these to the shift sheet:

Cash in and Cash out record money added to or taken from the drawer (a float top-up, a supplier paid in cash) with a reason.
No sale opens the drawer without a sale and logs it.
End of day shows the End of day (Z report) for every shift, and Print Z report sends it to the receipt printer.

X read (mid-shift totals) shows the shift totals so far without closing it. With blind drawer close on, it needs the manager passcode.

Timeo warns you about open orders and offline sales that have not synced yet. Settle them first, or a manager can press Close anyway.

Nothing changes for customers. Owners see every shift in Reports under End of day and Z-report.
