Hello,
Making your expenses billable to your customer is a common business practice, and it's important that QuickBooks Online allows you to do this with ease. If you don't want to add the expenses via a purchase order, you can use the Billable Expense feature to add these directly to their invoice. I'll explain the steps.
Billable expenses are available in QuickBooks Online Plus. A billable expense is an expense you incur on your customer’s behalf when you perform a work for them. You can easily record and track billable expenses so your customer can reimburse them when they receive their invoice.
Follow these steps to create a billable expense: Enter billable expenses. Add each billable expense to each of your 3 customers in order to have them cover the cost.
I hope this helps. If you have any other questions, please contact our tech support team.
Have a great day.
