The short version

  • Only SignWell has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; SignWell the free plan stops at three documents a month, which makes it a trial rather than a tier, so any genuine use converts to a paid seat within weeks.
  • They diverge on capability: Microsoft 365 covers Office applications, SignWell covers Per-sender pricing.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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.

SignWell

  • The free plan stops at three documents a month, which makes it a trial rather than a tier, so any genuine use converts to a paid seat within weeks.
  • Pricing is per sender, so an organisation where many people occasionally need to send something either buys seats for staff who send a handful of documents a year or funnels everything through one person and creates a bottleneck.
  • Templates are rationed by tier, at one on free and five per sender on the entry plan, and templates are what makes the tool worth using at all, so the practical entry point is a tier above the headline price.
  • It is a smaller vendor in a category where signed agreements must be retrievable years later, so the safe practice is downloading every signed document and its audit certificate into your own storage rather than relying on the account still existing.
  • It provides standard electronic signatures rather than acting as a qualified trust service provider, so any transaction requiring a qualified electronic signature under European rules needs a different supplier alongside it.

Answered from the vendors’ own pages

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.

SignWell: Do signers need an account or a licence?

No. Recipients open a link, sign and are done, with no account and no cost. You pay only for the people who send documents.

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.

SignWell: What does the free plan actually allow?

Three documents a month, one sender and one template, along with a small monthly allowance of API documents. It does not include custom branding or bulk send.

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.

SignWell: Is an electronic signature legally binding?

Electronic signatures are recognised for most commercial agreements under the relevant American and European frameworks, and SignWell records an audit trail. Certain instruments are excluded by statute, and anything requiring a qualified signature needs a qualified provider.

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.

SignWell: How hard is it to leave?

The signed documents are ordinary PDFs you can download with their certificates, so the records move easily. Your templates and the workflows built around them do not.
