When accessing the system and going to an employee's record, a message is displayed that someone else is accessing it but no one is logged in

Sage Business Cloud Payroll Professional is not a website where if you launched it, you can just click on the red cross and close the page. In closing the system in that manner means you are closing it unnaturally, leaving files open in the backend.

To prevent this from happening it is extremely important to remember that when you are busy working in a company and you want to close it, to select the Close Company option on the far right hand side

Once the company has been closed you will be returned to the company listing screen from where you can then close the site and will be prompted to confirm this by selecting to leave the site

You will now be returned to the landing page where all your systems/site codes are.
