Late Night Logistics Best calculadora adicional noturno tools?

[pisog]

Hi everyone, 

since my brand is based in Dubai but ships worldwide, I often find myself or my team working odd hours to accommodate different time zones. 

I need a reliable calculadora adicional noturno to ensure everyone is being compensated fairly for their late-night dedication to customer service. 

Dealing with luxury watches and jewelry means we have to be available when the client is, regardless of the clock! Is there an app or a simple high-quality spreadsheet you use to calculate these premiums automatically? 

I want to stay professional and beyond reproach with my payroll.

Thanks in advance.
