Link an actual expense to the customer’s project so you can review it with the job.
1. Open the expense form
Go to Purchases → Expenses → New Expense, or edit an eligible existing cost.
2. Enter the cost
Review the title, date, amount, currency, tax, expense category, and Paid From account. Attach the receipt if you have one.
3. Choose the customer and project
Choose the customer first, then select the appropriate Project from that customer’s projects. If none is shown, check the selected customer and whether its project exists.
4. Save and review the job
Save the expense. Open Worklog → Projects, select the project, and check Expenses. Eligible unbilled expenses can be selected later in the invoice wizard; linking alone does not charge the customer.
