The short version

  • Only SurveyCTO 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.; SurveyCTO pricing is by submission volume, forms and storage rather than by users, so a small team running continuous high-volume collection can pay more than a 200-person survey team that runs for six weeks
  • They diverge on capability: Invoca covers Dynamic number insertion, SurveyCTO covers Offline collection.
  • Prices and features above were last checked on 1 September 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.

SurveyCTO

  • Pricing is by submission volume, forms and storage rather than by users, so a small team running continuous high-volume collection can pay more than a 200-person survey team that runs for six weeks
  • Forms are authored in XLSForm spreadsheet syntax, which is precise and versionable but has a real learning curve, and organisations without someone comfortable in it stall at form design
  • Overage is charged at 100 US dollars per 1,000 extra submissions, which is easy to trigger on the Basic tier at 5,000 a month and produces surprise invoices during an active field round
  • Server region selection only appears on the Pro tier and a custom GDPR data processing agreement only on Advanced, so European data protection requirements push the price to at least 315 and often 630 dollars a month regardless of volume
  • It is built for structured research fieldwork, not for business process forms, so it has no dispatch, no invoicing and no formatted document output, and a field service business would be buying the wrong tool

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.

SurveyCTO: Do I pay per enumerator?

No. Users and devices are unlimited on every paid tier. You pay for monthly submissions, forms and storage.

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.

SurveyCTO: Is there a free version?

Yes, a permanent community subscription with 10 forms, 200 monthly submissions and 200 MB of storage, intended for testing and training rather than production.

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.

SurveyCTO: What happens if I exceed my submissions?

Extra credits are 100 US dollars per 1,000, with discounts of 20 per cent or more at volume. Plan the tier around your peak field month, not your average.

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

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

SurveyCTO: Can I choose where the data is stored?

Only on Pro and above. If data residency matters, budget for at least the Pro tier.
