Adding new business with existing account

We just added a new business but it seems only the summary, settings, journal and reports tab is active. I cant customize for invoices, or any other account even payroll
Any help?

At the bottom left there is a customise link
Open it and enable the tabs you need in your business

See the guide

By the way. Have a look through the guide index. No one reads all the guides initially however it is useful to know the sort of information covered by them. https://www.manager.io/guides/

This behavior is exactly as should be. Read the Guide: https://www.manager.io/guides/9265.
