Different departments, with different addresses, bank accounts, contact details, tax details, under the same company operate under the same Tax ID. Departments with different Tax ID’s are separate companies.
Separate companies may be added to your subscription when you are using the Basic plan and upwards.
Companies or departments under one account
If you are adding a new company or department under one account, then all clients and products are mutual. In every account type you may add an unlimited amount of departments, however separate companies may be added from the Basic plan and onwards.
You may add a new company or department to your account by going Settings > Company / departments > Add new company or add new department.
Separate department numbering
You may choose whether you wish to have separate numbering for each department. However, within one account, the software does not allow you to have two invoices with the same number per year. If you want to have separate numbering, it is best to add a letter or number that defines the department at the very beginning. That way every department will have separate numbering.
Companies as separate accounts
For every account you can add a new company as a separate account (they have different client and product base). Go to Settings > Company / departments > Add new company.
After adding a new company you can manage it using the same login and password, as well as switch between them easily.
