One account is used to manage the benefits of the beneficiaries added to it. Beneficiaries can be divided across different invoices, and the account can have multiple admins. The same admin can also manage multiple accounts.
You can choose to split beneficiaries' ticket purchases across more than one invoice. This is useful if you want separate invoices, for example, by department or by the type of benefit issued to the beneficiary (for example, employees receiving auto-renewing season tickets on one invoice and employees receiving a mobility budget on another).
A single account is often suitable for small and medium-sized businesses.
