The short version

  • Only Polar has a free tier, so it costs nothing to try first.
  • Each has a real cost: Polar percentage-based fees higher than some specialized processors for high-volume transactions; Protel the vendor is now a payments company, so the economics of a deal run through card processing rates as much as software fees, and a hotel with good existing acquiring terms may lose more on processing than it saves on licence.
  • They diverge on capability: Polar covers Usage Billing, Protel covers Front desk and reservations.
  • 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.

Polar

  • Percentage-based fees higher than some specialized processors for high-volume transactions
  • Merchant of record model may not suit companies preferring direct payment control
  • Free Starter tier limited with 5% fees reducing appeal for production use
  • Setup and integration effort required despite API simplicity

Protel

  • The vendor is now a payments company, so the economics of a deal run through card processing rates as much as software fees, and a hotel with good existing acquiring terms may lose more on processing than it saves on licence.
  • The Protel name persists on the product but the corporate identity has moved to Planet, which makes contract, support and roadmap ownership harder to pin down than it looks from the product page.
  • Hotels on the older on-premise edition face a migration to cloud that is a re-implementation rather than an upgrade, with the data and interface work that implies.
  • Nothing about pricing is published, so a buyer cannot benchmark against Mews or Cloudbeds without a full sales process.
  • Strength is concentrated in German-speaking Europe and the Middle East; support depth and partner ecosystem are noticeably thinner in North America and Asia Pacific.
