The short version

  • Only LimeSurvey 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.; LimeSurvey self-hosting shifts patching, backups and PHP upgrades onto your own team, and neglected installations become a security liability holding participant data.
  • They diverge on capability: Invoca covers Dynamic number insertion, LimeSurvey covers Self-hosted deployment.
  • 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.

LimeSurvey

  • Self-hosting shifts patching, backups and PHP upgrades onto your own team, and neglected installations become a security liability holding participant data.
  • The default interface and themes look dated beside Typeform or Jotform, which measurably lowers completion rates on consumer-facing surveys.
  • Cloud plans are capped on responses per period, so an unexpectedly successful field wave can force an upgrade in the middle of data collection.
  • Serious theming and layout changes require template and CSS work rather than a visual designer, so agencies often budget developer time per project.
  • Support on the free edition is community forums only, and paid support is a separate purchase, which is a poor fit for teams with no technical staff.

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.

LimeSurvey: Is LimeSurvey really free?

The self-hosted Community Edition is free under the GPL with no vendor response limits. The hosted cloud is paid and tiered by response volume.

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.

LimeSurvey: Where is cloud data stored?

On servers in Germany, which is why public sector and academic buyers choose it over United States hosted competitors.

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.

LimeSurvey: Can it handle complex research designs?

Yes. Quotas, randomisation, piping and matrix question types are core features rather than enterprise add-ons.

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

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