I need to add a percentage for my night shifts and weekends. How do I do that?

You could create two additional sales items:

1. % Sunday shift, where you set the base price x the percentage as the price and in the description XX% on the original base price

2. % night shifts, where you set the base price x the percentage as the price and in the description YY% on the original base price</

   You then enter 3 lines on each invoice

   1. base price x amount of hours

   2. % Sunday service: base price % Sunday service x amount of hours

   3. % night shifts: base price % night shifts x amount of hours
