Current offers and older references are different

The public annual offers checked September 18 are Core $15, Engage $25 and Scale $75 per user per month. Nextiva limits its advertised annual small-business pricing to new customers with 1 to 100 employees and a paid minimum term of 12 months. Confirm eligibility and the complete order before using these figures as a budget. Source: Nextiva plans, feature matrix and offer conditions.

8x8 currently requests a custom quote: 8x8’s current pricing page. Neither a blanket “Nextiva is cheaper” claim nor a guaranteed discount is justified without equal-scope proposals.

Corrected June reference by seat band

Source: our 8x8 and Nextiva calculator references, last verified June 7, 2026. Above 500 seats, request a current deal-specific proposal; no discount band is published.

The June 7, 2026 reference used in our calculators is a different pricing basis. It is retained for explaining seat-band arithmetic, not presented as a current vendor offer. Do not apply its discount percentages to a new promotion or assume a partner quote will beat the vendor’s advertised price.

Worked comparison: 50 phone users

On that June basis, 50 X2 seats × $22 = $1,100 per month and 50 Core seats × $24 = $1,200. The difference is $100 per month or $1,200 over 12 months. Those entry plans are not feature-identical.

Nextiva’s current $15 advertised Core offer would calculate to $750 for the same number of users if the business qualifies. A current 8x8 quote is needed to compare today’s choices. The older table is not evidence that either vendor is currently cheaper.

Example assumptions: US dollars, annual commitment, base subscriptions only. Taxes, regulatory charges, hardware, implementation, porting work, usage and optional services are excluded unless the written proposal includes them. Annual totals are monthly amounts multiplied by 12, not a statement about invoice timing.

Start with destinations and user roles

For X-Series proposals, 8x8’s calling-country list distinguishes X2 calling to 14 countries from X4 calling to 48, subject to the applicable conditions. This describes outbound calling destinations, not the number of countries where you can obtain local numbers.

• List the countries and number types actually called, then compare them with the included destinations and exclusions in the proposal.
• Separate ordinary callers from supervisors and contact-center agents. Ask which licenses each group needs.
• Price X2 and X4 for the same total headcount, contract length and deployment scope. Ask whether mixed plans retain the quoted volume band.
• Request separate contact-center licensing and implementation costs. Do not assume an X2 or X4 phone seat includes a full contact center.
• Test local-number availability, call routing, recording retention and CRM behavior for every required location.

When to keep Nextiva on the shortlist

For a business centered on domestic calling and customer-service workflows, test Core, Engage or Scale against the actual queue and integration requirements. Price recording, CRM access and AI receptionist usage explicitly. The number of countries in a bundle only matters when staff call those destinations.

What to get in writing before choosing

• One inventory of users, shared phones, locations and numbers to port, used by every bidder.
• The exact plan for each user group and a line item for every required integration, recording feature and support service.
• A demonstration of your actual call flow, including busy queues, after-hours calls and transfers to a mobile user.
• A complete first invoice, implementation scope, renewal terms, cancellation notice and the rules for adding or removing seats.
• A porting owner, confirmed cutover plan and rollback contacts. Keep the old service active until transfers and testing are complete.
