The short answer
Editorial assessmentWhatConverts compared with Quo (formerly OpenPhone)
These solve adjacent problems and are frequently bought together. 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 but never which ad caused it. WhatConverts sits in front of a system like Quo, attributes the inbound call to a campaign, and forwards it through. A local business advertising on Google reasonably needs both, and they cost less together than one seat of most enterprise alternatives.
Choose Quo (formerly OpenPhone) if
Small businesses, agencies, trades, and founder-led sales teams who need a shared work number with texting, light routing, and CRM logging, and who make dozens of calls a day rather than hundreds. Anyone who wants a business phone that costs less than a lunch per seat and can be live in an afternoon.
Choose WhatConverts if
Small businesses that generate leads by phone and spend money on advertising to do it, and especially the marketing agencies serving them: home services, legal, medical and dental, automotive, real estate, and any local business where the phone is the conversion event and the ad platform cannot see it.

| Best for | Small businesses, agencies, trades, and founder-led sales teams who need a shared work number with texting, light routing, and CRM logging, and who make dozens of calls a day rather than hundreds.

| Setup time | Under an hour for a solo user and about half a day for a small team. Choose a number, install the apps, set business hours and a ring group, and you are live. Number porting takes longer, typically one to two weeks, and runs in parallel while you use a temporary number. | Under an hour for a basic deployment: create an account, add the tracking script to your site, provision a number pool, and set a forwarding destination. Attribution starts working on the next visitor. Connecting Google Ads, building call flows, and configuring qualification rules add a few hours of setup that is worth doing properly rather than quickly. |
| Learning curve | Near zero. The interface is a messaging app with a keypad, and staff who have never used a business phone system understand it without training. The only genuinely unfamiliar concept is A2P 10DLC registration, which the product walks you through. | Low for the mechanics and moderate for the discipline. Installing the script and seeing attributed calls is easy. The genuine learning is operational: getting staff to qualify leads consistently, sizing the number pool correctly for your traffic, and resisting the urge to judge campaigns on call volume rather than qualified value. |

Strengths and limitations
Quo (formerly OpenPhone)
Strengths
- The shared-number inbox with internal comments and assignment is the single best small-team phone experience on the market and is why the product spreads by word of mouth.
- A phone number is included in every seat, unlimited US and Canada calling is on the cheapest tier, and there is no seat minimum, so the entry cost is genuinely $15.
- API access on every plan including Starter, which most competitors reserve for their top tier or a custom contract.
- Setup is measured in minutes, not days: pick a number, install apps, invite the team. No PBX concepts, no dial plans, no reseller.
Limitations
- No dialer of any kind: no power dialing, no parallel lines, no answering machine detection, no local presence rotation. For a real outbound motion this is disqualifying.
- Unlimited calling stops at the US and Canadian border, and international is metered, which makes cost modelling awkward for anyone selling across regions.
- Call recording, CRM logging, and phone menus are all gated behind the Business tier, so the advertised $15 entry price is not the price most buyers actually pay.
- The Scale tier at $35 mostly buys support and call tags. The value curve flattens hard after Business.
WhatConverts
Strengths
- Answers the question no phone system in this category can answer: which ad, campaign, and keyword produced this specific phone call.
- Tracks calls, forms, chats, and ecommerce transactions in one attributed dashboard, so the marketing report covers every conversion path rather than only the phone.
- Excellent agency tooling: white label with your own logo and domain, unlimited sub-accounts on agency plans, branded reports, emails, and invoices, and cheaper unit rates at that level.
- One-click lead qualification is a deceptively important design decision, because it converts raw call volume into a report about revenue rather than a report about ringing.
Limitations
- The credit-based pricing is less predictable than a competitor's included-numbers allowance, and a realistic deployment often costs double the plan sticker once numbers and minutes are counted.
- Keyword-level reporting, form tracking, chat tracking, and the Google Ads integration all require the $60 Plus tier, so the $30 headline is misleading for the most common use case.
- Purely an inbound product. There is no dialer, no outbound calling workflow, and nothing to help a sales team place calls.
- It is not a phone system. Call flows and IVR exist to route tracked calls, but there are no user extensions, desk phones, internal dialing, or team messaging.
Pricing compared
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.
WhatConverts
Monthly subscription with a bundled usage credit rather than a fixed allowance: each plan includes a credit ($30 on single accounts, $250 to $400 on agency plans) which is consumed by tracking numbers, minutes, transcription, texts, and non-call lead events at published per-unit rates, with overage billed beyond the credit.
- Call Tracking (single account)$30
- Plus (single account)$60
- Pro (single account)$100
- Elite (single account)$160
- Agency plans (unlimited accounts)$500 Plus / $800 Pro / $1,250 Elite
WhatConverts is the best-value serious call tracking product for a small business or a small agency, and the reason is focus rather than feature count. At $60 on Plus, plus perhaps $60 to $90 of realistic usage, you get keyword-level attribution, form and chat tracking, recording, cheap transcription, one-click qualification, enhanced conversions back to Google Ads, and API access, from a bootstrapped company whose entire product is this problem. The credit model is the thing to watch: it is honest but it is not predictable, and buyers who plan a twenty-number pool without doing the arithmetic will be unpleasantly surprised in month one. Note also what this product is not: there is no dialer and no outbound calling story at all, so the standard three-person team making 100 calls a day scenario simply does not apply here. WhatConverts measures the calls that come in, which for an advertising local business is usually the more valuable half of the phone.
Editorial verdict on each
Quo (formerly OpenPhone)
Quo is the best small-business phone system you can buy for the money, and it is not an outbound sales tool. The shared-number inbox, the included number in every seat, the absence of a seat minimum, and API access on the cheapest plan add up to a product that a two-person company can adopt in an afternoon and never think about again. Business at $23 with recording, transcripts, AI summaries, and HubSpot or Salesforce write-back is the tier to buy. What you do not get is any dialer, any local presence rotation, any spam remediation, or unlimited calling beyond North America, and those absences are the whole difference between this category's phone systems and its dialers. If your reps work lists, buy Kixie or PhoneBurner. If customers call you and you call them back, buy Quo and stop shopping.
Read the full Quo (formerly OpenPhone) profileWhatConverts
WhatConverts fills the most conspicuous gap in this category for a local business: knowing which advertising produced which phone call. It does that job cleanly, tracks forms, chats, and transactions alongside calls so the whole conversion picture lives in one place, and its one-click qualification workflow is the quiet design decision that turns call volume into a revenue report. For agencies it is close to ideal, with white labelling, unlimited sub-accounts, and cheaper unit rates from $500 a month. Two warnings. First, the $30 headline is not the price of the product most people want: keyword-level attribution and form tracking start at $60. Second, the credit model means a realistic deployment often costs roughly double the plan sticker once numbers and minutes are counted, so size your number pool before you sign up. And be clear about what it is not: there is no dialer, no outbound workflow, and no phone system here. This sits in front of your phone, tells you where the call came from, and passes it through.
