How to get that access? Is it the same as role of inhouse accountant.

What access are you referring to? In QuickBooks Online (QBO), the inhouse accountant role can do everything related to customers, sales, vendors, and purchases but it can’t do payroll, manage other roles, or perform admin tasks.

If you want a role that provides almost the same level of access as the inhouse accountant, you can choose either the Standard all access role or the Primary admin/Company admin roles. Refer to this article for the slight differences: User roles and access rights.
