The office suite feature that pays off later is structure, not styling

A suite ships hundreds of functions and you will use perhaps thirty. What decides a purchase is whether the specific capabilities your work depends on are present, and whether they behave properly on documents the size of yours.

What to take away

Structure is the feature that pays off later

Everything below concerns whether a document is built or merely typed.

Named styles. Formatting applied by style can be changed everywhere at once. Formatting applied by selecting text cannot be changed at all without doing it again. A suite that makes styles awkward is a suite that guarantees direct formatting, and the cost lands two years later when the branding changes.

Automatic numbering that survives editing. Headings, clauses, figures, and tables should renumber when something is inserted in the middle. Test this by inserting a section at the top of a long document and watching what happens below.

Cross references that update. A reference to "section 4.2" that stays as text after 4.2 becomes 4.3 is a defect waiting to be published. In Word a cross reference is a field, so the number follows the heading. Google Docs has no equivalent field, so a reference there is text you maintain by hand.

Generated contents, figures, and indexes. Check that they regenerate and that their links still work after an export.

Sections with independent layout. Different page orientation, headers, or numbering within one document. In Word this is a section break. Whether it is supported decides whether a report with a wide sideways appendix is one file or three.

The ten minute test: take your longest real document, insert a new second level heading near the front, add a figure, and regenerate the contents. Then look at whether the numbering, the references, and the contents are all correct.

If your test document lives in shared storage, the office suite setup defaults decide whether those regenerated links survive the next save.

In spreadsheets, look for the error prevention

Function coverage matters and is rarely the differentiator. These are:

Excel keeps validation and tracing on the Data and Formulas tabs. Google Sheets keeps validation and named ranges on the Data menu. Test the suite you have against the six above; a missing one is a gap you will meet later.

Test your own largest workbook. Change one input near the bottom of the dependency chain. Time how long the whole thing takes to settle.

Then break a link on purpose. See whether the failure is visible or silent. Silent is the answer that should worry you.

A workbook that breaks links when storage moves is the format fidelity problem that decides office suites.

Review mechanics, tested with a real second person

Collaboration features are demonstrated with two windows on one screen, which proves nothing about how a review actually goes.

The mechanics worth checking:

Word shows markup in a side pane on the Review tab. Google Docs puts comments and suggestions in one panel, with a separate editing mode for suggestions. Both are testable in a single session.

The real test: have a colleague comment and suggest changes on a document while you edit it, resolve half the threads, then export the file and open the export somewhere else. What survived tells you what your review process can rely on.

Accessibility tooling, which is also a structure check

Whether or not you have an obligation, this tooling is worth using, because it detects the structural problems that cause every other kind of failure. Where an obligation does apply, it is normally a purchasing requirement rather than something to remediate afterwards, which is the point of the guidance on buying accessible products and services.

A document that passes these checks almost always converts cleanly, exports cleanly, and can be restyled later.

A document that fails them was assembled without structure.

Test the tooling by running the checker over three real documents from different people in your organization. The results tell you as much about your templates and habits as about the software.

Automation, and what it costs to keep

Macros and scripts do not move between suites. VBA and Office Scripts are tied to Microsoft 365, Apps Script to Google Workspace, Basic to LibreOffice, and AppleScript or JavaScript to Apple. Work written for one has to be rebuilt for another.

That belongs in the evaluation before it belongs in the budget. Microsoft blocks macros in files downloaded from the internet by default, a change it made in 2022 across Word, Excel, PowerPoint, Access, and Visio. An automation distributed by email now needs a documented workaround and someone who owns it.

Two things set the maintenance cost. The first is reach. A macro that formats a document keeps one skill current. One that writes to a database, a mail system, or a shared drive is an integration with its own owner and its own failure modes.

The second is how many automations you run, because each one breaks when the vendor ships an update. No vendor publishes that number for you. Count your own before you compare candidates.

Two questions remain per candidate. What language is the automation written in, and who in your organization could maintain it? Who may install and run it? Without administrative control over installs, an automation platform is an extra integration surface, not a feature.

Add ins deserve the same treatment. Check what permissions one asks for, whether an administrator can restrict the catalog, and what happens when the vendor of an add in you depend on stops publishing it.

Anything that reaches outside the suite is an interface with its own maintenance, and treating it that way from the start is the point of published API and data standards: a connection nobody documented is a connection nobody can fix.

Which features to weigh, and how much

Fill this in for your own work before you test anything, and the shortlist of what to test becomes short. The worked example row shows the shape of the answer: list what you produce, then mark each group. The classification of your document work is the input to this table, and it is worth doing first.

Common questions

Are the assistive and generative features worth evaluating?

Try them, weight them lightly. They change quickly, they are appearing across the whole category, and a suite chosen for one of them will be judged on everything else for years afterward.

How many templates and fonts should we care about?

Almost none. Counts of included content are marketing. What matters is whether your own templates work properly and whether the fonts you actually use are available to everyone who opens your documents, which is a decision to make during rollout rather than a feature to shop for.

What about the difference between browser and installed versions?

Assume the browser version has fewer of the structure, automation, and auditing features described here, and test the specific ones you need rather than trusting a general answer. This is the most common gap between what was demonstrated and what people get.

We have no long documents or models. Does any of this matter?

Then most of it does not, and you should choose on cost, on what your people already know, and on how easily you could leave. Not every organization has a hard requirement here, and pretending otherwise is how a simple decision becomes a project.
