These tools don't publish a numeric price with a currency (often "contact sales"), so they can't be ranked.
Compare Business Phone System prices head to head
How we compute this
- For each tool and team size we take the cheapest published plan that fits: per-user plans cost the unit price × users (respecting any stated minimum or seat pack), plans that include some users cost their base price plus the extra-user price for each additional user, flat plans cost their flat price when the vendor states a user limit (or unlimited users) and are otherwise counted as one licence per user, and plans whose stated user cap is below the team size are skipped. Intro and promotional prices are replaced by the list price, and usage-based prices (per transfer, per hour…) are left out.
- Prices are vendor list prices before taxes, add-ons and discounts. Annual billing is shown as the effective price per month.
- Only tools priced in the most common currency (USD) are ranked; we never convert prices to rank them. ≈ amounts are indicative conversions at the ECB reference rate.
- Cheapest by list price is not the same as best value: features and limits differ between plans. Free plans are flagged but not counted as a price, because their user limits vary.
