CTM (CallTrackingMetrics) vs Quo (formerly OpenPhone)

CTM (CallTrackingMetrics) compared with Quo (formerly OpenPhone)

Quo (formerly OpenPhone) is a business phone system at $15 to $35 a seat with a shared inbox, texting, and CRM logging. It can tell you a call happened; it has no idea which ad caused it. CTM answers that question and can also handle the call, but it lacks Quo's shared-inbox collaboration, per-user numbers, and general phone-system behaviour. A marketing-led small business commonly runs both, with CTM in front attributing and Quo behind it as the team's phone.

CTM (CallTrackingMetrics)

Flat monthly plan with unlimited tracking sources and unlimited users on every tier, discounted on annual and two-year terms, with usage charged separately: minutes, numbers, transcription beyond included pools, AI activities, and chats, plus optional agent bundles and volume discount packs.

• Marketing Lite$79 monthly / $65 annual / $60 two-year
• Marketing Pro$179 monthly / $149 annual / $135 two-year
• Sales Engage$329 monthly / $274 annual / $247 two-year
• Enterprise$1,999

CTM's value depends entirely on whether you use both halves of it. Bought purely as attribution, $65 a month annually is more than double WhatConverts' $30 entry price for a broadly similar answer, and the case is thin. Bought as attribution plus a calling platform, the arithmetic changes sharply, because unlimited users means a five-person intake team on Sales Engage at $274 annually costs the same as one person, where a per-seat competitor plus a separate call tracking product would run well past that. The genuinely strong tiers are Marketing Pro for agencies at $149 annually, where sub-accounts, white labelling, HIPAA, the API, and 3,000 transcribed minutes per sub-account arrive together, and Sales Engage for businesses that want their phone team living inside the attribution platform. Note that the standard three-person team making 100 calls a day scenario mostly does not apply: CTM's smart dialer exists but this is an inbound-first product, and 6,300 outbound calls a month would be worked through agent bundles at $99 a seat plus per-minute usage rather than through a seat price with unlimited minutes.

Quo (formerly OpenPhone)

Per-user per-month subscription with a number included in every seat, unlimited US and Canada calling and messaging on all tiers, and usage-based charges only for international calling, extra numbers, automated SMS, and AI credits.

• Starter$15
• Business$23
• Scale$35

At $23 a seat for recording, transcripts, AI summaries, and CRM write-back, Business is the best price-to-capability ratio in small-business phone, and the fact that a number is included rather than billed separately quietly saves another few dollars a seat against Aircall or CloudTalk. The value case collapses only in two places: heavy international traffic, which is metered, and outbound dialing, which does not exist here at all. Judged as a phone system for a company under 30 people, it is underpriced. Judged as a sales dialer, it is not competing.
