Is the Products and Services management not available with Self-Employed? I can 'edit saved item' in the invoice, but can't adjust any other paramaters of the items.

Thank you for reaching out, customers.
 

I understand that you're having trouble adjusting parameters for items in QuickBooks Self-Employed (QBSE). Could you please clarify which parameters you're referring to? This will help me better understand the issue and provide you with the appropriate solution.
 

I look forward to hearing back from you. Best regards.
