Hi there, vdpassafiume. Thanks for reaching out to the Community.
Currently, there isn't an ability to merge two different accounts. However, multiple companies can be attached to an account. Each one would be a separate paid plan, but you'd access them using the same login information. This makes switching between companies quicker and enables users to efficiently manage their data.
