Microsoft Office 365 is well established as the leading office software suite. At just under £140 per user per year for the Business Premium edition, its not unreasonably priced especially compared with the stand alone desktop version at £250. However, if money is really tight and you need something free, what are the alternatives?

Zoho Office Suite
Zoho is a web based online office suite similar to Google Docs, Sheets & Slides. It includes a word processor (Writer), spreadsheet (Sheet), presentation software (Show) and a selection of other applications.
LibreOffice and Open Office have a shared development history so the different application in the suite have the same names. Like Open Office, it is desktop only software. According to Wikipedia, it is the most actively developed free and open source office suite, with approximately 50 times the development activity of Open Office.
FreeOffice is another desktop only office suite developed by SoftMaker. It includes a word processor (TextMaker), spreadsheet (PlanMaker), and a presentation software (SoftMaker Presentations).
