All those design and IT companies that have a large budget and can not afford the luxury as it is certified software are free to rely on the opportunities offered by free software. There are really excellent free alternatives that would have performed the same tasks that offer expensive software. In this paper I offer an excellent substitute for expensive and well known software to Microsoft.First Editing documents (Microsoft Office)

One of the most used products of Microsoft's set of tools for editing documents, Microsoft Office. This software seems to know really, if you want to save, then LibreOffice is the right choice.
LibreOffice is very similar to Microsoft Office, drastically differing only in names. So, Microsoft Word called Libre Writer, Microsoft Excel is Libre Calc, Microsoft PowerPoint is Libre Impress, while Microsoft Access is Libre Base.
Interestingly, the Libre is a tool that had its own unique characteristics, such as the ability Libre Writer be used as a basic WYSIWYG editor, while Libre Calc includes a system which automatically defines series of graphs. LibreOffice, and almost every free software can be used on any operating system.
Other alternatives are Google Docs, Zoho Office and Open Office certainly an excellent alternative.Second Software project management (Microsoft Project)
Microsoft software for managing various projects, Microsoft Project, no problem can be replaced by a free web application Project Open, which performs the same work, plus more.
Project Open provides project planning, managing resources, import and export projects from other software to manage, such as OpenProj, GnattProject and Microsoft Project. In addition, Project Open also provides IT management services, financial management, managing human resources, and many other features that Microsoft Project does not have.
A similar tool Project Open e OpenERP, software which includes sales, CRM, project management, warehouse management, accounting, and human resources.
Other alternatives to OpenProj and Gantt Project.Third Software for e-mail and calendar (Microsoft Outlook)
An excellent free alternative to Microsoft Outlook is Mozilla Thunderbird, an application that can be combined with plaginite calendar, Lightning or Sunbird. Thunderbird, unlike Outlook is far faster, and has excellent unnecessary mail filters, HTML support allows multiple identities, support for POP and IMAP, as well as excellent security features.
Thunderbird also has an excellent search system, so now the list of results, appear all the people mentioned in messages received from the search, this allows further refinement of the results to just clicking on the names. Another interesting feature is a reminder of accessories. If the message stand words like "attachment", "attached," or "enclosed" Thunderbird gives a warning that should be attached document.
