If you searched “OpenPhone pricing” recently and landed somewhere unexpected, that’s not a mistake on your part — OpenPhone rebranded to Quo in September 2025, alongside a $105 million growth round and a repositioning around an AI voice agent called Sona. The underlying phone-number product is the same one small teams have used for years; it just lives at quo.com now, with OpenPhone’s name kept around mostly in search results and old links. This guide uses the current Quo pricing (what you’ll actually be charged if you sign up today) and compares it plan-by-plan against KrispCall, the other small-team phone-number app most OpenPhone/Quo shoppers end up cross-shopping against — see also CASRAI’s independent KrispCall review for the full verdict.

The short version before the tier-by-tier breakdown: at comparable seat counts, KrispCall runs 15-25% cheaper than Quo’s equivalent plans, though it trades away Quo’s more built-out AI receptionist and native HubSpot/Salesforce integrations to get there — see the feature-parity and honest-tradeoff sections below before assuming price alone decides it.
OpenPhone (Quo) pricing plans, as of August 2026
Quo runs three per-user tiers, billed monthly or annually (annual billing is meaningfully cheaper on every tier):
| Plan | Monthly | Annual (per user/mo) | What’s included |
|---|---|---|---|
| Starter | $19/user | $15/user | 1 phone number, unlimited US/Canada calling & SMS, voicemail transcripts, shared number for up to 10 users, Sona AI agent (1,000 free automation credits/mo), API access |
| Business | $33/user | $23/user | Everything in Starter, plus AI call summaries & transcripts, unlimited shared numbers, call transfers, custom ring orders, phone menus, analytics, auto call recording, HubSpot & Salesforce integrations, live chat support |
| Scale | $47/user | $35/user | Everything in Business, plus AI call tags, dedicated onboarding, priority support, inbound phone support |
Extra phone numbers beyond the first are $5/month each on any tier; international calling and SMS are billed per-minute/per-message on top of the subscription. Sona, the AI receptionist, comes bundled with 1,000 free credits a month across all plans — heavier automation usage draws down that allotment and can add cost.
KrispCall pricing plans, as of August 2026
KrispCall prices lower at every comparable tier and structures its plans around unlimited users rather than an AI-agent add-on:
| Plan | Monthly | Annual (per user/mo) | What’s included |
|---|---|---|---|
| Essential | $15/user | $12/user | Up to 5 users, one free US/Canada/UK number each, call recording, voicemail, IVR, shared inbox |
| Standard | $40/user | $32/user | Unlimited users, unlimited storage, API access, call monitoring, everything in Essential |
| Enterprise | Custom | Custom | Negotiated volume pricing, dedicated support |
Calls and SMS are metered on top of the subscription on every KrispCall tier, and numbers outside the US, Canada and UK are a paid add-on — the same usage-based structure Quo uses for international traffic, so that part of the bill is roughly a wash between the two.

Head-to-head: where KrispCall actually costs less
Lining the tiers up by what each includes, not just by name:
- Entry tier — Quo Starter is $19/$15 (monthly/annual) for one number and one seat’s worth of shared access (up to 10 users on a single shared number). KrispCall Essential is $15/$12 and already includes a shared inbox and IVR at that price, though it caps out at 5 users on the tier before you need Standard.
- Mid tier — Quo Business is $33/$23 for the integrations most small teams actually want (HubSpot, Salesforce, call transfers, analytics). KrispCall Standard is $40/$32 for unlimited users and storage, but its integration list is thinner — no native HubSpot or Salesforce CTI comparable to Quo’s.
- Per extra number — Quo charges a flat $5/month per additional number on any plan. KrispCall doesn’t publish a flat per-number add-on rate as cleanly; a team that needs several numbers per seat (e.g., a department running multiple project lines) should get a direct quote before assuming parity.
- Net effect for a small team standardizing on core calling/texting/shared-inbox features without needing HubSpot/Salesforce CTI — KrispCall’s Essential and Standard tiers run 15-25% cheaper than Quo’s Starter and Business equivalents at the same seat count, annual billing.
Feature parity: what you keep, what you give up
The two products overlap heavily — shared numbers, call recording, voicemail transcription, API access, IVR — but they’ve diverged in two real ways worth knowing before you switch:
- AI receptionist depth. Quo’s Sona is a more developed autonomous voice agent (lead qualification, mid-call SMS follow-up, FAQ handling) bundled into every tier with a monthly credit allotment. KrispCall’s AI features are comparatively lighter — call summaries and basic automation rather than a standalone voice agent. If an AI receptionist handling inbound calls unattended is the actual reason you’re shopping, that tips toward Quo.
- CRM integrations. Quo Business/Scale ship native HubSpot and Salesforce integrations. KrispCall’s integration set is narrower and doesn’t include comparable native CRM CTI at the same tier. A team whose workflow already runs through HubSpot or Salesforce pipelines will feel this gap immediately after switching.
- Where they’re equivalent. Core small-business telephony — shared inbox, call recording, IVR, voicemail-to-text, unlimited US/Canada calling, a real API — is genuinely comparable between the two at this point. Neither is missing table-stakes functionality the other has.
Who should NOT switch to KrispCall
The honest version of this comparison isn’t “KrispCall wins”: teams already standardized on OpenPhone’s (Quo’s) Slack and HubSpot/Salesforce integrations, or its shared-inbox number workflow, may find the switching cost — rebuilding automations, retraining staff on a new inbox, re-porting numbers — outweighs KrispCall’s price edge. If your team runs sales or support workflows that already lean on Quo’s native CRM integrations day-to-day, stay put; the 15-25% you’d save doesn’t cover what you’d spend re-wiring those workflows elsewhere. KrispCall’s price advantage is most worth acting on for a team that’s choosing a phone system fresh, or one whose CRM integration needs are light enough that the gap doesn’t matter.

Frequently asked questions
What are OpenPhone’s pricing plans called now?
OpenPhone rebranded to Quo in September 2025. The three plans are named Starter ($19/mo, $15/mo billed annually), Business ($33/mo, $23/mo annually), and Scale ($47/mo, $35/mo annually) — all per user.
Is OpenPhone still a separate product from Quo?
No. Quo is the same company and the same underlying phone-number product under a new name and brand positioning (an “AI-driven front office” rather than just a business phone line). There is no separate OpenPhone product to buy anymore as of this writing.
How much does an extra phone number cost on OpenPhone/Quo vs KrispCall?
Quo charges a flat $5/month for each additional number beyond the first, on any plan. KrispCall doesn’t publish an equally simple flat per-number add-on rate; get a direct quote if your team needs several numbers per seat.
Is KrispCall cheaper than OpenPhone (Quo)?
At comparable tiers, yes — KrispCall’s Essential ($12-15/user) and Standard ($32-40/user) plans run below Quo’s Starter ($15-19/user) and Business ($23-33/user) equivalents. The gap narrows or reverses in effective value once you weigh in Quo’s more built-out AI receptionist (Sona) and native HubSpot/Salesforce integrations, which KrispCall doesn’t match at the same tier.
Does KrispCall have the same integrations as OpenPhone?
Not quite. Quo’s Business and Scale tiers include native HubSpot and Salesforce integrations; KrispCall’s integration list is narrower and doesn’t include comparable native CRM CTI. Core telephony features (shared inbox, recording, IVR, API access) are comparable between the two.
