What Is QuickBooks Error QBWC1013?
QuickBooks Error QBWC1013 is a connection error that occurs when the QuickBooks Web Connector cannot establish a successful connection with QuickBooks Desktop. The Web Connector is a utility that allows third-party applications to exchange data with QuickBooks Desktop, and this error indicates a failure in that communication channel .
When this error appears:
When running the QuickBooks Web Connector to sync data
When a third-party application attempts to connect to QuickBooks Desktop
When QuickBooks Desktop is closed during a scheduled sync
After updating QuickBooks Desktop or Windows
When the company file path has changed or is incorrect
Common error messages users may see:
"QBWC1013: Error connecting to QuickBooks. Could not start QuickBooks"
"QBWC1013: Error connecting to QuickBooks. Returning error message to application"
"If the QuickBooks company data file is not open, a call to the BeginSession method must include the name of the data file"
This issue affects QuickBooks Desktop Pro, Premier, and Enterprise users who utilize the Web Connector for integrations with e-commerce platforms, CRM systems, payment processors, and other third-party applications . The error signals authentication failures, permission issues, file path problems, or network connectivity problems that prevent successful data exchange .
Common Causes of QuickBooks Error QBWC1013
Understanding the root cause of QBWC1013 error accelerates your fix. Below are the most frequent triggers identified by Intuit support and integration specialists .
QuickBooks Company File Not Open
The Web Connector requires QuickBooks Desktop to be open when syncing unless a company file path is explicitly provided . If QuickBooks is closed when a sync is attempted, this error appears.
Incorrect or Missing Company File Path
If you have configured the Web Connector to sync with QuickBooks while it is closed, the file path provided must be exact . An incorrect path or a path with typos will trigger this error. The path must end with .qbw and follow the exact format, such as C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files.qbw .
Integrated Application Not Authorized
QuickBooks requires explicit permission for third-party applications to access company files. If the application has not been authorized, or if authorization has been revoked, the Web Connector cannot connect . This is indicated by the message "This application is not allowed to log into this QuickBooks company data file automatically" .
Integrated Application Not Set to Allow Automatic Login
Even after authorization, the application must be configured to allow automatic login in QuickBooks' Integrated Application preferences . Without this setting, the Web Connector cannot establish an automated connection.
Company File Moved or Renamed
If the QuickBooks company file has been moved to a different folder or renamed, the Web Connector cannot locate it . This requires re-authorization or updating the file path.
QuickBooks User Account Has No Password
The QuickBooks administrator user must have a password set. The Web Connector will not work properly if the Admin user has no password .
Multiple Company Files Open
If multiple QuickBooks company files are open, the Web Connector may attempt to connect to the wrong file, causing authentication errors . Only the company file intended for sync should be open.
Web Connector Running in Multi-User Mode
The Web Connector works best when QuickBooks is in Single-User Mode . Running in Multi-User Mode can cause connection issues.
Incorrect Username or Password in Web Connector
The username and password stored in the Web Connector for the integrated application must match the credentials expected by that application. An incorrect password will trigger authentication failures .
