Employees work Invoices?

I use every day Manager.io, and have good working experience with it.
But I miss one module, Employees work Invoices or Employees confirmation.
Combined with Employees, Sales Invoices and Customers…

Are there opportunities for this module?

I am curious. Can you explain what an employee work invoice is and what it does? In normal accounting terminology, an invoice is evidence of an obligation to pay the originating party for delivery of goods or services. In Manager, a sales invoice is given by the accounting entity to a customer; a purchase invoice is how we record invoices sent to the entity by suppliers.

Are you referring to the ability to record working hours or jobs completed in support of issuing payslips?
