Accrual Method - For expense time and material (project)

Dear Community,

I would like to know what accrual method I should use for the following scenario.

I have a customer project on which I only have expenses or pass-through. It is bill back to the customer at actual cost.

Example :

Meal and Entertainment: 10$

On my sales order, I used a service set up as “Expense”, Item Type: Expenses - Time and Materials (Project)

No bill has been issued yet to the customer. And we do not want to trigger an invoice at this point.

I need to close the month.

I would like to recognize 10$ of cost and 10$ of revenue.

Which accrual method would enable me to achieve this result automatically?

Thank you.,

Andréanne
