Welcome to the Community space, @dpanimal7574. We'll point you in the right direction to get this sorted so you can select or add a customer when creating and sending invoices inside QuickBooks Self-Employed (QBSE).
Before anything else, please know it isn't the experience we want you to have when utilizing the invoice feature of the program. We highly recommend contacting our Customer Care Team so they can access your account in a secure environment and conduct further investigation. This way, they can provide the necessary steps to troubleshoot this situation and restore the program to its default function so you can get back to creating an invoice and selecting customers for the transaction. We'll write down the steps to get you going:
- Access your QuickBooks Self-Employed company.
- On the top right corner, click the Help (?) and select Contact Us.
- Enter “talk to a human”, then select Continue.
- Select Have us call you or Chat with us to start a conversation with a support expert.
