The Maxwell Systems, Inc. developers, the ones who created American Contractor were acquired by Viewpoint, but with the acquisition, the software doesn't appear to be available anymore in terms of support, selling, troubleshooting, updates, etc.
I've tried finding a manual or a way to obtain guides related to adding another company in American Contractor, but it doesn't exist anything for this purpose. In some cases, apps like this one work only with a single company, therefore lacking the possibility of adding another one.
