ONLYOFFICE
How to sell positively against ONLYOFFICE Docs as an Office Online Server replacement. Used by the BoldDocServer GTM plan and competitive selling.
Summary
ONLYOFFICE Docs is an open-source online editor suite (documents, spreadsheets, presentations, PDF) based on Office Open XML formats. Its SharePoint app adds an “Edit in ONLYOFFICE” option to document libraries, and it positions itself as a direct OOS replacement. It runs self-hosted or in the cloud, with free and Enterprise editions (TODO: verify edition and pricing model from their pricing page).
Details
BoldDocServer (Office Online Server replacement)
Where they’re strong
- Native OOXML editing across documents, spreadsheets and presentations, with an AI plugin and JavaScript macros.
- Connectors for many platforms (SharePoint, Confluence, ownCloud and others), useful for mixed estates.
- Open source, plus cloud and self-hosted options.
Where we fit better
- Plugs in where OOS did, through the SharePoint WOPI binding, so users keep the familiar open-in-browser flow instead of a separate menu option.
- Focused on SharePoint Server with a container deployment beside the farm and SharePoint’s own per-user, per-file tokens.
- Public per-user pricing with volume bands.
Positive talk track “ONLYOFFICE is a capable suite, especially if you need one editor across many platforms. If SharePoint Server is the platform and you want to restore the OOS experience exactly where users expect it, BoldDocServer is the focused fit.”
Landmines to avoid
- Don’t claim their connector doesn’t support SharePoint Server versions without checking. TODO: verify supported SharePoint versions.
- Don’t disparage open source.
