About Sync Manager
The Sync Manager automatically starts running when you open the QB Desktop and syncs 
the changes in the business data with the servers. The syncing is performed at regular time 
intervals and helps to keep the data updated in the servers and vice versa. You might run 
into several errors due to this Sync Manager when the data sync is hindered. These errors 
create an annoying situation as they are repetitive and can affect the ongoing tasks in the 
software. You’ll receive error messages instantly when the Sync Manager fails to exchange 
data with the Intuit servers, and the message will keep interrupting you until the issue is 
fixed. Sync manager issues don’t affect your financial data, and you have no reason to 
worry about it. As explained later in this blog, sync manager issues can be easily countered 
by configuring some system and QBDT settings.
Triggers
Sync manager errors primarily develop due to network connection issues or interruption of QB 
background processes. We have compiled a list of some specific reasons that are influential in 
developing these issues-
• Sync Manager fails to run in the background due to restrictions of the Windows Firewall or 
other security software on your system.
• Unstable network connection or a low internet speed on your system can cause a timeout in 
the server connection.
• It is possible that the software is working fine, and there’s a problem at the server end.
• Data sync automatically fails when the company file is damaged, or its data is corrupted.
• QuickBooks program files might be missing or damaged, which causes issues when the 
software runs on your computer.
• The time & date in your system are inaccurate, leading to issues when the server tries 
to sync the timings.
• Intuit Sync Manager might not have the required permissions to access the system files 
due to the non-admin Windows account.
Solutions
You won’t be able to utilize the software efficiently, as error messages will repeatedly occur 
when Sync Manager stops running in the background. Use the following techniques to 
resolve data syncing issue from your QuickBooks-
Method 1- Remove QB Data sync manager from your system and erase 
its settings
You can also face trouble syncing QB data if the Sync Manager generates some internal 
glitches and stops running. Error messages like ‘An update is available’ will start filling up 
your screen whenever the data sync fails, and you’ll be forbidden from executing any other 
task. In some cases, it has been observed that the software crashes randomly due to 
hindrances in the data sync. You can resolve the issue by removing Sync Manager from 
your system as described in the steps below-
• Click the up arrow on your taskbar to open the system tray.
• Right-click the Intuit Sync Manager icon and right-click on a company file.
• Go to the Sync Enabled menu and click Disable in the drop-down menu.
• Repeat these steps on all the company files to stop them from syncing.
Once the Intuit sync manager is disabled on your system, you must clear the sync settings 
from your QuickBooks to prevent issues in the future. Use these steps-
• Go to the QuickBooks Help menu and click Manage Data Sync.
• Hit the Clear sync settings option and tap Yes to confirm.
• Tap Ok to continue.
The above-given steps will erase all the sync settings that can also trigger issues in the 
software. As the final step, you must now remove Intuit Sync Manager from QuickBooks 
preferences and turn off the automatic updates as shown in the steps below-
• Open the Edit menu, then select Preferences.
• Tap Integrated Applications and select Company Preferences.
• Single-click Intuit Sync Manager to highlight it and hit Remove.
• Open the Help menu in your QuickBooks and select Update QuickBooks Desktop.
• Click Options and hit the Turn off automatic updates option.
• Start QuickBooks again to see if the issue has been resolved.
In case the syncing issues appear again while using the software, move to the next method.
Method 2- Check the Internet speed of your network connection and set 
up TLS settings correctly
Data syncing issues become common if there are network connectivity issues in your system. 
The data sync fails instantly when the software loses its connection to the internet, and error 
messages start recurring. This can happen if the Internet speed on your system isn’t 
adequate to run QBDT smoothly. You can check your internet speed using the steps 
mentioned below and compare them with the QBDT requirements of 3Mbps average and 
1.5Mbps minimum. Use the following steps-
• Launch your web browser and visit the Google homepage.
• Type ‘internet speed test’ in the search panel and press Enter or click Google Search.
• Click on the first link in the search results and click Start in the next window to run the test.
• Let the test complete and compare the internet speed with the QB requirements.
If the internet speed isn’t good enough to run QuickBooks, you are advised to change your 
network service provider or upgrade the hardware (modem, cables), whichever is required. 
On the other hand, if you find that the internet speed on your system is satisfactory, you 
must proceed with the following steps to configure your TLS settings. Transport Layer 
Security is responsible for protecting your PC from malware and other malicious risks when 
accessing the internet. Your PC applications will struggle to use the internet if these 
settings are strictly set. Here are the steps to fix your system’s TLS settings-
• Open the Run window using the Windows + R keys on your keyboard.
• Ensure the command field is blank and type ‘inetcpl.cpl.’
• Press Enter to go to the Internet Properties and move to the Advanced tab.
• Go down the settings list to find Use TLS 1.2 and mark its checkbox with a single click.
• Tap Apply to save the settings and close the window.
• Reopen QuickBooks to check if the data syncing issues are removed.
Try the next solution if the issues bother you again while working on the software.
Method 3- Use the Verify Rebuild utility to fix damaged QB program files
If QB program files and other data become damaged, the sync manager will also fail to 
exchange data with the servers. The software might face trouble executing other tasks tool 
and malfunction when it fails to retrieve its program files. You can fix the issues by repairing 
your QB data using the Verify-Rebuild utility tool, as shown in the steps below-
• Open your QuickBooks and click the File menu at the top.
• Select Utilities in the drop-down list and tap Rebuild data.
• If necessary, click “Ok” when prompted to create a backup before rebuilding your data.
• Go to the File menu again after completion of the rebuilding process and tap Utilities.
• Click Verify data and let the utility scan the data for any remaining issues.
• If you encounter a ‘Your data has lost integrity’ error message on the screen, click the 
Rebuild Now option.
• Let the process finish and reopen QuickBooks.
If the syncing issues develop again in your QuickBooks, jump to the next solution.
Method 4- Allow QuickBooks to bypass the Windows Firewall restrictions 
and open the software in Admin mode
Intuit Sync Manager can also generate issues if it gets blocked by the Windows firewall from 
using the internet or integrating with web applications. You can resolve the issue by configuring 
the Windows Firewall settings on your system to prevent QBDT from getting blocked. Use the 
steps mentioned below-
• Go to the control panel on your system and open the Windows Defender Firewall menu.
• Click the Allow an app or feature through Windows Firewall option located on the left and 
scroll down the program list to find QuickBooks.
• Single-click QuickBooks to highlight it and mark the Public & Private checkboxes beside it.
• Save the settings by clicking Apply and close the control panel menu.
Once you have fixed the Windows Firewall settings, you should utilize QBDT in admin mode. 
This will grant it access to all system files and give it priority when utilizing system resources. 
Here are the steps you need to follow-
• Right-click the software launch icon inside the QB folder and click Properties.
• Go to the Compatibility tab and select Run this program as Administrator checkbox.
The above-given methods will resolve data sync issues from QuickBooks.
