I have a stingy SME boss who always likes to ask staff to pay for meals/cabs ect and submit claims at the end of the month for payment at the end of the following month is this normal?

I wont mind that a bit... as in it helps me to get points.

It's normal to submit staff claim once a month, accounts is easier to track and pay all staff at the same time monthly.

Valid SOP. No organisation, not even MNCs or government bodies, provides on-demand claims reimbursement. Otherwise, it would be very messy to track. Also, if the claims reimbursement come together with your following monthly pay, normal too.

It's normal... a lot of big companies are like that too. You're alr lucky you can claim. Some SMEs don't even let people claim anything at all.
