Methodology — how these numbers are built

Pricing is scraped from each provider's public pricing page in April 2026. Every calculation is deterministic — change any input and the math updates live.

Provider pricing sources + verification status

On 2026-04-22 we ran a Playwright stealth browser against each provider's public pricing page and compared the rendered numbers against what's in this tool. ✓ verified = prices match provider's live page. ~ estimated = provider's page is JS-rendered or blocks scrapers; numbers are the most recent public data we have but should be re-confirmed before any procurement decision.

Hidden-cost assumptions

  • Setup fee: $99 one-time (industry median; RingCentral $0, 8x8 $99, Nextiva $200, Dialpad $0)
  • Phone hardware (if toggled): $130 per user (Polycom/Yealink entry model)
  • Number porting: $15 per user (actual waived by most — kept as worst-case)
  • Overage modeling: assumes 20% of users exceed monthly minutes by 500 min at $0.03/min
  • Add-on integrations: $10/user/month (Salesforce/HubSpot premium connectors on mid-tier plans)
  • Growth projection: linearly applied across 36 months

Feature-fit scoring

For each feature you rate, providers receive a 0-100 score based on (a) whether the feature is included at that plan tier (public docs), (b) third-party signal from G2, Capterra, and Gartner Peer Insights review aggregates, and (c) operational experience with our own product plus direct-competitor evaluations. Scores are an opinion, not a measurement — weight them against your own research. Your priority weights then determine the fit score shown in the table.

What's NOT included

  • Enterprise contract discounts (10-30% common above 100 users — ask the provider)
  • First-month promotional pricing (often 50% off month 1)
  • Implementation professional services (one-off, $2-10k for complex deployments)
  • International toll-free numbers (vary wildly by country)
  • SIP trunking supplement for legacy PBX bridging
