Why am I getting a QuickBooks error code?

QuickBooks has more than 500 error codes.  The vast majority of them stem from some type of data corruption in the backend database, a problem when upgrading or changing the file (we recommend never upgrading more than 1 year at a time for this reason), or a problem with permissions.

However, most error codes can stem from one of multiple issues, so without getting into the back end of the software and Sybase database it is near impossible to determine the root case. Although each error code comes with suggested steps to fix it, we find that these rarely work and are difficult to properly execute without backend training. If you are getting served an error code we can help you determine the issue, fix the corrupted data, and return a new file with no errors.

Customer Story

Fourlane’s File Review process uncovers hidden problems and provides solutions to QuickBooks issues

Contemporary Research’s financials were not accurate and their QuickBooks file was 20 years old and crashed daily and inventory numbers were off. In addition, they did not have an accurate picture of its product costs because the bill of materials for assembly items wasn’t set up properly.

We have worked with Alisha Raesz at Fourlane for over 2 years. She has helped us navigate building new QB files for two companies and has been a lifesaver is keeping our QB file up to date. We consider Alisha a part of the CR team. She is extremely professional and always willing to teach us how to make changes and updates the correct way. We can't thank Alisha and the entire Fourlane team enough for helping us organize our company so we can grow! I highly recommend Alisha if you are in need of an experienced Quickbooks professional.

Our company has worked several times with Fourlane, and we could not be happier! They are both responsive and professional, and Fourlane constantly impresses with both the quality of the reports they produces for us, as well as the quick timelines he's able to adhere to (and beat at times!) If it was possible to give more than 5 stars I would, because that's just how satisfied we have been working with Fourlane.

I've been through a few different software conversions. Each of them was stressful and difficult. Fourlane made our conversion from Microsoft Dynamics Great Plains to Quickbooks Online as simple and painless as I've experienced. Every aspect was top notch. Kaylin Leland was awesome and very patient with us as our staff had varying levels or prior experience with QB. Trisha Thomas managed the project exceptionally well and was checking in frequently to make sure we were happy with every aspect. I would HIGHLY recommend Fourlane for anyone looking to transition to Quickbooks.
