The short version

  • Only Microsoft Forms has a free tier, so it costs nothing to try first.
  • Each has a real cost: Invoca entry pricing commonly starts around 1,500 US dollars a month before call minutes, plus a setup and training fee, which prices out agencies and small businesses that only need attribution for a few hundred calls.; Microsoft Forms the Advanced Data Residency add-on explicitly does not cover Microsoft Forms, so a tenant that has paid for regional residency still has its survey responses provisioned according to best-effort guidance rather than a contractual commitment.
  • They diverge on capability: Invoca covers Dynamic number insertion, Microsoft Forms covers Bundled licensing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Invoca

  • Entry pricing commonly starts around 1,500 US dollars a month before call minutes, plus a setup and training fee, which prices out agencies and small businesses that only need attribution for a few hundred calls.
  • Telephony minutes and tracking numbers are metered separately from the platform fee, so a seasonal advertising spike produces an invoice nobody forecast.
  • Signal AI, PreSense and quality management are frequently sold as add-on modules rather than included, meaning the demo you were shown may cost noticeably more than the quote you were given.
  • Contracts are annual or multi-year with usage minimums and no month-to-month option, so a campaign strategy that shifts away from phone calls leaves you paying for capacity you no longer use.
  • The product is deep on inbound phone attribution and shallow elsewhere; if your buying journey also involves chat, forms and in-store visits, Invoca covers only one channel and you still need a separate attribution model for the rest.

Microsoft Forms

  • The Advanced Data Residency add-on explicitly does not cover Microsoft Forms, so a tenant that has paid for regional residency still has its survey responses provisioned according to best-effort guidance rather than a contractual commitment.
  • Above 50,000 responses a form degrades sharply: only CSV export continues to work, while summary charts, viewing individual responses, printing, shared summary links and manual quiz grading all stop.
  • Forms belonging to an account that is hard deleted, or deleted more than thirty days earlier, are not recoverable at all, so an unmanaged leaver process destroys survey data silently.
  • The administrator settings that govern external sharing, template sharing and result summary sharing are only available to education and Microsoft 365 Apps for business customers, leaving many commercial tenants without the controls the documentation describes.
  • A summary sharing link that has already been created continues to work for anyone inside or outside the organisation even after the form is restricted, so tightening permissions does not close an existing leak unless the link is deleted explicitly.

Answered from the vendors’ own pages

Invoca: Does Invoca publish prices?

No. Every deal is quoted from call volume, number count and which modules you licence. Independent reports put the entry point near 1,500 US dollars a month plus minutes.

Microsoft Forms: Can I buy Microsoft Forms on its own?

No. It exists only as a service plan inside Microsoft 365, Office 365 and education or government SKUs, or free with a consumer Microsoft account. There is no standalone product to purchase.

Invoca: Is this different from CallRail?

Yes, in ambition and price. Invoca targets enterprise attribution with automated outcome classification fed back to ad bidding; lighter call tracking tools stop at source attribution.

Microsoft Forms: Where are responses stored?

In the United States for most tenants, in the EU and EFTA region for EU tenants, and in Australia only for Forms provisioned after October 2022. Microsoft states this is guidance, not a residency commitment.

Invoca: Is it HIPAA compatible?

Invoca sells heavily into healthcare and offers redaction and compliance controls for regulated recordings; confirm the specific terms in your contract.

Microsoft Forms: Can an administrator read someone else responses?

Not while that user account is active; ownership transfer is refused. Yes once the account is disabled or deleted, and yes through premium eDiscovery, which is still labelled preview.

Invoca: Do we need a contact centre platform as well?

Yes. Invoca tracks and analyses calls, it does not run your contact centre.

Microsoft Forms: How do I turn Forms off for the organisation?

Disable both the Microsoft Forms and the Office Hive enterprise applications in Entra ID, or clear the Forms checkbox per user. Both applications must be disabled for it to take effect.
