Hi everyone, 

I am currently finalizing a new partnership with a luxury jewelry supplier and we need to be extremely specific about the delivery windows in our contract. 

In the professional world of high-end retail, a few days can make a huge difference in revenue and customer satisfaction. 

I need to ensure that my count accounts for every single holiday and weekend with zero margin for error to stay established. 

What do you use when you need to calcular dias úteis com precisão?

Thanks in advance.
