Error 350 in QuickBooks Desktop during a rebuild process usually indicates corruption within the company file that QuickBooks' built-in tools (Verify/Rebuild and File Doctor) are unable to fix. Since you've already worked with QuickBooks support and used their repair tools without success, here are some advanced steps to try:
1. Create a Portable Company File & Restore
A portable company file (.qbm) strips out some data corruption and can sometimes fix issues that a regular backup cannot.
Steps:
- Open QuickBooks and go to File > Create Copy
- Select Portable company file (.qbm) and follow the prompts to save it
- Close QuickBooks
- Reopen QuickBooks and restore the portable file by going to File > Open or Restore Company > Restore a portable file
- Try running the Verify/Rebuild Data tool again
2. Manually Recreate the File via Excel & IIF Import
If the file is heavily corrupted, you may need to manually extract and re-enter data:
- Export lists and transactions to Excel/IIF
- Create a new company file
- Import back-in the data
3. Use QuickBooks Auto Data Recovery (ADR) – If Available
QuickBooks Auto Data Recovery (ADR) creates backups of your company file. If enabled, you can attempt a restore.
Steps:
- Navigate to your QuickBooks company file folder
- Look for the .adr files (e.g.,
CompanyName.qbw.adr) - Rename your damaged .qbw file and copy the .adr version, renaming it back to .qbw
- Open QuickBooks and check if the issue persists
4. Try Third-Party QuickBooks Repair Tools
Intuit’s built-in tools have limitations. Third-party tools like Stellar Repair for QuickBooks or DataNumen QuickBooks Repair can sometimes recover data from a corrupt QuickBooks file when standard tools fail.
5. Consider Professional Data Recovery Services
If the corruption is severe and you cannot rebuild the file at all, Intuit offers a QuickBooks Data Recovery Service where they manually repair the file. Alternatively, we at Pacific Northwest Computers can assist with QuickBooks data file recovery.
If none of these steps resolve the issue, your best bet may be to restore from a recent unaffected backup and manually re-enter any missing transactions.
