When first using Bookkeeper, if the Accounts Receivable and Invoices screens are not highlighted/selectable or they appear "grayed out", you must first create a customer in the Customer screen before they can be accessed.
To create a customer:
- Click on to the Customer screen.
- Click the Add button.
- Enter in the customer information in the fields.
- Click OK.
After creating a customer the Accounts Receivable and Invoices screens will be available.
