DocHaven simple to use, but all of the DMS, CRM, cash register and messaging systems display identically on Macintosh, Windows and Linux systems. Installations can be run in a single computer, non-networked, standalone way linking to an SQLite database. Should you need to share your CRM or contacts, then you can move the system onto a MySQL server. DocHaven is also a cloud-based library for your documents. DocHaven is free to download and use, but since it stores lots of data on the HMS server there is a rental charge for continued use. This charge is $9 per user per month or $99 per user per year.
