How can I get an estimates tab on my main business feed ?

QuickBooks Self-Employed (QBSE) doesn’t include an Estimates feature, as it’s designed to help freelancers and independent contractors track income, expenses, mileage, and taxes, Cypress.

If you need to manage estimates, consider switching to QuickBooks Solopreneurs or QuickBooks Online (QBO). These plans include an Estimates feature that allows you to create, send, and convert  into invoices, along with advanced accounting tools.
