How do I make employee-based payment? (Interval's Customer)

This is something we call cost tracking and it is not something that Intervals does. The reason it doesn't is that it would make the currently elegant interface for estimating work messy and complicated. However, we do have some ideas for you on how you can generate invoices for Mary and Andrew, based on how we've done the same for our subcontractors.

We primarily leave it up to the subcontractor to invoice us using their own invoicing system. But first they log into Intervals and run a report to see how many ours they've worked in a given date range. Then they do the math themselves and generate the invoice.

If your goal is to pass along Mary and Andrews work to the client, but with a markup, then I would suggest adding their fees as an expense, but don't charge the customer for them. This will create financial reports that show your profit, because they will exclude zeroed out fees. For example, for a project, add an expense and put their total amount you paid them as a project expense. But then leave the customer fee at zero.

We hope this helps you adjust your invoices a bit easier into our Intervals time tracking and project management software.
