How do I record counter invoice payments where my customer deduct my costs to them automatically in the Remittance and provide me with their invoice at the same time?

I've got you covered, gary83.

Let's record the transactions as billable expenses in QuickBooks Online. Before proceeding, let's turn on the tracking feature. I'll guide you how.

1. Go to the Gear icon and then select Account and Settings.
2. Select the Expenses tab.
3. From the Bills and expenses section, select Edit ✎.
4. Turn on the following:
   • Show Items table on expense and purchase forms
   • Track expenses and items by customer.
5. Select Save.

Then, follow the steps below to bill a customer for an expense.

1. Go to + New.
2. Select Expense.
3. Choose the payee.
4. In the Category column, select the expense account for the transaction.
5. Enter the description and amount of the expense, then select the Billable checkbox.
6. In the Customer column, select the customer you want to bill for this expense.
7. Select Save and close.

Once done, you can now reimburse the cost by linking the billable expense to your customer's invoice.

1. Go + New.
2. Select Invoice.
3. In the Customer ▼ dropdown menu, select the customer you created a billable expense for. This opens the Add to invoice window.
4. Select Add on the billable expense you want to charge to your customer.
5. Click Save and close.
