American Contractor software was a solid choice for construction businesses when it was first released in 1983. Maxwell Systems bought the company in 2000. In 2014, Viewpoint Construction Software acquired Maxwell Systems, which joined the Trimble family of products a few years later.
Many contractors have enjoyed it as an industry-leading program and would love to continue using for years into the future. That said, some American Contractor users may be looking to gain more long-term support and hardware compatibility, more product growth and development, and more stability.
While they have several options in front of them, one option is to convert their data over to FOUNDATION construction accounting software.
So, just what would that look like?

Key Takeaways for Contractors: American Contractor to FOUNDATION Migration Essentials
- In today’s competitive construction industry, making the transition from American Contractor software solutions to FOUNDATION provides construction teams with a comprehensive toolset that maintains familiar workflows while introducing essential features modern contracting businesses need.
- Foundation Software’s data migration process ensures your historical construction job cost accounting information transfers seamlessly, allowing for informed decisions without sacrificing the detailed insights you’ve accumulated over years of operation.
- Effective project cost tracking, a critical feature of contractor accounting, remains uninterrupted during the transition, helping successful contractors maintain their competitive edge while managing ongoing construction projects.
- The thoughtful implementation approach, developed specifically for former American Contractor users, provides a clear pathway to adopting FOUNDATION as your new comprehensive contractor accounting software with minimal business disruption and maximum long-term stability.

Why American Contractor Users Get Excited About FOUNDATION
Clients who do move to FOUNDATION can look forward to a number of highlights that we’ve seen former American Contractor users love about switching.
Additionally, only one company has owned FOUNDATION and taken care of its clients exclusively since Version 1.0. Foundation Accounting Software has been free of outside investors since we started in 1985, and we’ve always refused acquisition offers, because we’re really that committed to giving our clients stability.
What’s the Learning Curve for American Contractor Users?
What to Expect From the Differences
New construction accounting software will never be exactly like your old software, and many differences are neither good nor bad — just different.
Fortunately, a lot of how FOUNDATION is set up will make sense to American Contractor users. Both FOUNDATION and American Contractor are designed for similar-sized companies, and moving from construction software to construction software, you’ll see a lot of similarities.
At the same time, some things might feel less familiar or be a small change. To take a little fear out of the unknown, here are some of the bigger differences you can expect.
Other than that? Some things do have different names, which you’ll get the hang of quickly. And you’ll need to hit “Tab” instead of “Enter” to key through fields.
What to Expect From Implementation
Once you decide to move ahead with our team, we use a five-phase approach to get you running successfully:
How Long Does It Take to Get Started?
We would love to tell you exactly when you could plan to run live on FOUNDATION. However, it depends in large part on a number of factors.
- How prepared your office is for the change
- How prepared your accounting is and any cleanup that’s required in your financial data
- How much dedicated time your team can commit
In our experience, we find that most contractors are best positioned for success with roughly 35-50 hours of training on new construction accounting software.
And in order to practice, get comfortable and instill long-term learning, those hours do need to be spaced out. Contractors with lasting success will typically allow for three to six months, from change planning through wrap-up and review.
That time is a long-term investment in construction accounting software you want to be getting the most out of and growing with for the next five, 10 or more years.
Having developed FOUNDATION and other products and services for this long as a fully independent company, we have every confidence we’ll be with you down the road to support your business.
