What does the login link to the TPIN mean?

The Login email-user-name you registered with will ALWAYS be linked to the company TPIN. In order to keep all email correspondence coming to one email address for multiple companies, you can go to Settings (after you have registered a second Company) and then Company-Settings and change the Correspondence email to be the same email address for multiple companies. This means that once you have registered an additional company and change the email address for correspondence as described above, you will then receive all email renewal invoices etc on the same email address as the initial company registered. What you need to remember is the user login links with only one company TPIN and you keep that login to access the particular company. ie One login name can not access all payrolls. If you want to have an additional user to access the same company then you can send an email request for an extra user login. (A Once off charge of 50 USD is needed for this module). Normally this is done for big databases where there are multiple payroll users accessing one company. If your Login email address is no longer used then make sure the company correspondence-email is changed under Settings as described above so that it will always go to the correct address. In this case the login email is only used as a login and so it does not need to be changed. If you do want this login to change, then you need to request Admin under support@harvesteronline.net for this to be done. There is normally a small charge of 10 USD for this as it needs to be done securely and linked correctly with your company TPIN.
