What is this error?

Any error which describes a “connection lost” indicates that there is data damage in the backend Sybase file. Sybase is the database system that Intuit uses for all QuickBooks products. “Connection to company file has been lost” sometimes occurs after a QuickBooks update, after a change to your server or hosting setup, or sometimes for no reason at all.

This error code causes QuickBooks to close immediately and any unsaved data will be lost. It is likely to continue to occur if it is not resolved.

There is no frontend solution to solving this problem permanently. It must be solved in the backend by an experienced Sybase technician. They will solve the database corruption and restore the connectivity to your file.

JJ Luebbe | Luebbe Companies, LLC

We started with Fourlane specifically for Quickbooks point of sale help. Fourlane was awesome. They have incredible knowledge of Quickbooks. This year we added another layer of Fourlane help. We hired Fourlane for bookkeeping. We are thrilled that we did. LaTiffany is our day to day contact. She is incredible. LaTiffany has cleaned up, streamlined and maintained our accounting. LaTiffany and Fourlane are pleasures to work with.

Wendy Thomajan | Austin Foot & Ankle Specialists

I worked with Fourlane on a QuickBooks data conversion. They were extremely helpful and knowledgable. Helped us through a very rough patch smoothly. I would highly recommend Fourlane.

Brenda Shearer | Technical Specialties Corporation

Fourlane is helping us convert from NetSuite to Quickbooks. I'm very impressed with the professionalism and competency of everyone at Fourlane, without exception.

Jim Roundtree | Cinsay

I contacted Fourlane about QuickBooks POS. We needed some assistance with having our inventory program work with QuickBooks POS. Tarrah was helpful in this matter. While talking with her I discovered that Fourlane could assist my company with our QuickBooks as well as other concerns in my company. We are still in the process of changing our system and at the same time I have recommended some of my customers contact Tarrah.

Mike Patterson | Allied Inventory Services

Fourlane has been a great partner with our third-party software integration. The key to me is that when they are not 100% on an answer they do not try to resolve it “on-the-fly’ but go back and do research.

Derek Pennant-Jones | Celling Biosciences

No one likes to think about having to change accounting systems, particularly when you have been using the same system for over 20 years, but sure enough that day came for my firm in Texas recently. My firm is a distribution center for a pump manufacturer in Minneapolis. After searching for alternatives, I was unhappy with what I found, so I called Intuit, discussed our upcoming situation, and the first thing I wanted to know was, whom do I contact that would be considered experts at installation, training and manipulating Quickbooks. Without a drop of the hat, they recommended FOURLANE…If you ever had doubts of using their product or getting the support you would need, rest assured, FOURLANE is the way to go.

Jim Horany | Wanner Engineering

We have worked with Alisha Raesz from Fourlane for the past 6 months and have been so impressed with her knowledge and attention to detail. Alisha has guided us through a new company file changeover to help our manufacturing business grow and she has provided amazing customer service. We could not have done it without her help!

Christy Ricketts | Contemporary Research

Marjorie Adams and Tarrah Hendrickson were very helpful during the initial 30 minute consultation, which was free of charge! I had a complex issue and they were able to resolve it for me within the 30 minutes, so I ended up getting the advise for no charge, which my boss will love! Would definitely recommend as well as use Fourlane in the future.

Jill Blecher | Mass Polymers

Fourlane was unbelievably helpful to me when I wanted Quickbooks Premier for my company. I ordered for 1-user then wanted to add another. Then ended up wanting to add another and another. Linn was super helpful and was able to set me up where I continuously got credit for what I had already paid and in the end got all 4-users for less than the price of 3. She went above and beyond what most would do in her place. Anytime I need something and Fourlane has it, I will be purchasing from them.

P.S. This is the FIRST ever review I have given – positive or negative – so that is how much I valued the service I received from Linn and Fourlane.
