Errors in QuickBooks POS company data files after upgrade may occur if:


  • Instead of a server, Point of Sale has been installed on a client workstation.
  • The software is attempting to access the company database.
  • It is not possible to log in to the POS database service manager because it is not running.
  • Access to the company file has been lost.
  • There is a problem with the company file.
  • Using Windows XP SP2 as the operating system, the company file was converted to a higher version of Point of Sale.

The issue faced by the user is quite irregular and is met with few users, while other has been able to continue with their QuickBooks POS without much fuss. The problem creator is – Intuit Entitlement Service v6.0 which when integrates with QuickBooks Point of Sale v10 allows the user to connect the application and company file. However at times user ends up in a glitch and company file does not respond favorably with the QuickBooks POS software. This causes inaccessibility of the company file that starts interfering in the work flow of the business. One resolution of this issue is by restoring the backup company file, however, before trying to restore this backup ensures that the service is running properly or there is a chance that the data constructed since last backup might get lost. If the service is not running properly, then the remedy is to restart it which will allow for the company file to open without any hassle. For this purpose, user needs to be logged in with administrator credentials.

There are also many cases, wherein after upgrading to Windows OS 10, users have been able to open their QuickBooks Point of Sale v10.0 software but faced issue in connecting to the database. For this the best tip is to uninstall the QuickBooks POS software and then reinstall it.
