Your Software or Custom Built Software

Synchronize or Integrate

Intuit QuickBooks

We can work with your existing software or custom build new software that will interact with QuickBooks.

What is the difference between integration and synchronization?

Synchronization means that your software and QuickBooks work hand-in-hand to transfer information back and forth in real time. Over our years of experience with QuickBooks synchronization, we have developed a top-notch tool for this connection.

Integration typically involves importing and/or exporting of information to and from QuickBooks tables. These transactions take place at specific intervals in separate steps. We can help you determine whether integration or synchronization will meet your needs..

The prospect of exchanging information with QuickBooks can be overwhelming.
The good news is you have options.

Save Time and Money

Our goal will be to develop an effective solution that will save you both time and money.
Learn More
When determining whether to develop custom software, two of the critical factors are saving or gaining time and money.  All of the projects we have developed to synchronize with QuickBooks achieved these goals. We can explore the possibilities with you and provide guidance in many ways for the software and hardware involved in your information systems.

Financial Tracking

Do you need more detailed tracking on the progress of your large contracts?

We have experience working with large academic, commercial and government contracts that involve multiple stages, work assignments, tracking labor, material, overhead and other costs vs budgets, intricate fee structures, progress completions, reporting requirements and other details beyond the basic accounting and financial management of QuickBooks.

Custom Reporting

We can create new reports or combine QuickBooks with your existing data and create custom reports.

Learn More
QuickBooks has been remarkable in providing for the creation of a wide variety of reports based on criteria and formats set by the user.  If you need to go beyond the framework QuickBooks provides or if you need to combine your QuickBooks information with data from another software system, we can develop software to do this.

Converting Information

We have experience in transferring information from a variety of software systems and technologies to QuickBooks.
Learn More
From our work with a number of conversions, we have developed a protocol to transfer information from other software systems to QuickBooks tables for customers/jobs, items, employees, vendors and transactions.


If the other software can export to one of the industry standard formats such as Excel, CSV, SQL, this is the best scenario.   If the data format is not standard, we can explore to determine which fields of information can be transferred.

Custom Programming

We build powerful, cost-effective custom applications and add-ons for QuickBooks or as standalone softare.
