Small companies, freelancers, employees, HR departments, accountants and agencies all run into the same everyday questions: how much is a partial month of salary, how many working days are in a period, how much leave is left, what overtime is worth, how many hours a timesheet adds up to, and what a price looks like with or without VAT. Each tool answers one of those questions with a clear result and a visible calculation, so you can check the numbers and share them.
