The short version

  • Only DocuSeal has a free tier, so it costs nothing to try first.
  • Each has a real cost: DocuSeal free tier limited to 10 request emails per month; Microsoft 365 business plans are capped at 300 seats, so an organisation that grows past that must move to Enterprise plans, which changes both the price per user and the feature mix at the moment it can least afford a migration project.
  • Prices and features above were last checked on 30 August 2026.

  • A household that needs installed Office applications on several machines rather than browser-only editing.not DocuSeal

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

DocuSeal

  • Free tier limited to 10 request emails per month
  • API requires minimum one Pro seat at $20/month to access
  • API charges $0.20 per document signed in production

Microsoft 365

  • Business plans are capped at 300 seats, so an organisation that grows past that must move to Enterprise plans, which changes both the price per user and the feature mix at the moment it can least afford a migration project.
  • The compliance capabilities most organisations eventually need, including retention, data loss prevention, advanced eDiscovery and insider risk, sit at the top tier or in add-ons, so the real cost surfaces after an audit or a customer questionnaire rather than at purchase.
  • Annual term subscriptions commit you for the year and month-to-month terms cost measurably more per seat, so the flexibility to reduce seats during a quiet period is bought at a permanently higher rate.
  • Entra ID becomes the identity for everything else the organisation uses, which is the hardest kind of lock-in to put a number on, because leaving means re-federating every connected application rather than simply replacing a word processor.
  • The licensing model is complicated enough that most organisations are either over-licensed or quietly non-compliant, and reconciling it usually requires a partner or a specialist, which is a recurring cost that never appears in the advertised per-user figure.

Answered from the vendors’ own pages

DocuSeal: How much does DocuSeal cost?

DocuSeal offers a free Basic plan with 10 requests/month, Pro at $20/user/month ($200/year), and API at $0.20 per document signed in production.

Source
Microsoft 365: What is the difference between Microsoft 365 and Office?

Office was a one-off licence for a specific version. Microsoft 365 is a subscription covering the applications and the hosted services together, and when payment stops the applications drop to a reduced state rather than continuing as they were.

DocuSeal: Is DocuSeal free?

Yes, DocuSeal Basic is free with legally-binding eSignatures limited to 10 request emails per month and email support.

Source
Microsoft 365: Is Teams included?

Not automatically for newer customers. Microsoft unbundled Teams and now sells it alongside the suite, so check what a given quotation actually covers.

DocuSeal: What are DocuSeal's API costs?

DocuSeal API charges $0.20 per document signed in production. Requires at least one Pro seat ($20/month) to access API licensing keys.

Source
Microsoft 365: What happens to our files if we stop paying?

The documents remain yours and can be downloaded, but access to hosted mailboxes and sites ends after a retention window, so leaving requires a planned export rather than a cancellation.

Microsoft 365: Is Copilot part of the subscription?

No. It is a per-user add-on on top of the base licence, generally with its own term commitment, and it is priced per seat regardless of how much any individual uses it.
