I need to switch to cloud edition and want to know that 2 user can use same time with diffrent location with same id.
No. You need different IDs for different users. That is what allows simultaneous use. But there is no extra cost.
Sir in diffrent ids they work 2 times for 1 branch kindly guide and explain
There is nothing to explain. Multiple users of the cloud edition can log in and do whatever they have permission for in every business they have permissions defined. They can do that while other users do whatever they have permission to do. Read https://www.manager.io/guides/9162.
Go for 7 day trial and test drive this.
