MightyCall vs OpenPhone (Quo): what each costs, and which one dials

By Abhi Chawla, founder · Last updated October 29, 2026

MightyCall and OpenPhone, which now sells as Quo, are both small-business phone systems that start near $15 to $20 a user. The differences that change the bill are the ones the ranking pages skip: MightyCall’s three-user minimum, and the fact that only one of the two lets you dial a list.

TL;DR — our pick, and we build it

For a team comparing MightyCall and OpenPhone because it needs to make outbound calls, DialSheet is the pick: a power dialer and a 2–5 line parallel dialer in one $29 seat, month to month, with no seat minimum. Keep either phone system for inbound if you like; start free.

$56One DialSheet rep power-dialing 100 numbers a day for a month, Twilio included. MightyCall’s dialer starts at $162 (3 Power users); Quo sells none.
2–5Parallel lines per rep in the DialSheet seat. Neither phone system sells a parallel dialer to one rep.
$187An office of 5 on Quo Starter with 2 of them dialing on DialSheet, a month all in, against $270 for 5 MightyCall Power users.

Pick something else if nobody on the team dials lists (Quo is cheaper and simpler), you need an IVR, a HIPAA BAA and a dialer from one vendor (MightyCall), or you run three or more single-line reps past about 93 dials a day each on a yearly plan (MightyCall Power).

One correction. Google’s AI Overview for this query prices MightyCall “from $15” and Enterprise at $50. The live prices are $20 and $65 a user yearly, and the 3-user minimum it leaves out makes MightyCall’s real entry price $60 a month.

Where we lose. MightyCall Power bundles calling into a flat seat, so at three or more reps it costs less than DialSheet plus Twilio once each rep passes about 93 single-line dials a day. And if nobody dials lists, Quo Starter at $15 a user is cheaper than any dialer. A team of one or two, a team that pays by the month, or one that wants parallel dialing per rep is still better off on DialSheet.

DialSheet's parallel dialer rings several lines at once, screens voicemail, and connects the first person who answers. Watch the video or open it on YouTube.

Can you cold call with OpenPhone or MightyCall?

OpenPhone (Quo)

Click-to-call one number at a time, and the fair use policy bars auto-dialers. Reps who try to work a list from it paste numbers by hand. Our OpenPhone for cold calling guide covers the policy and the spam-label risk.

MightyCall

Yes, on Power and Enterprise: preview, progressive and predictive dialing, AI answering machine detection, local presence and Do Not Call Registry checks. The cost is the plan: $162 a month at minimum for the dialer.

On Pro, when a lead calls back, DialSheet rings the rep’s browser tab and phone together and matches the caller to the lead, which is the part of a phone system an outbound team misses most.

Callbacks: when a lead calls back, DialSheet rings you and shows who it is. Watch the video or open it on YouTube.

What DialSheet does not do

The free plan: 500 calls a month for $0 on your own Twilio, and when a $29 Pro seat with parallel dialing is worth it. Watch the video or open it on YouTube.

MightyCall, OpenPhone or DialSheet: which should you buy?

Our opinion, and we are not neutral

We build DialSheet, so weigh this accordingly. Having priced every dialer in this category line by line: for a team whose day is dialing a list, DialSheet does the same core job as MightyCall and Quo, with power dialing, call recordings and transcripts, AI call summaries, a built-in CRM and parallel dialing included in Pro, and it costs about $56 a month for one rep at 100 dials a day all in, against a $162 MightyCall dialer floor. It is also moving faster (we shipped 251 changes across 15 releases in the 30 days to September 8, 2026) because the people using it are the ones asking for the changes. Where it loses to MightyCall and Quo is narrow and specific, and it is listed below rather than buried. The teams running on it are published with their numbers at dialsheet.io/customers: a 12-seat UK accountancy practice that put a nine-rep calling floor live in a day, a two-person US acquisition team sustaining about 8,200 dials a month, a solo funding desk at 1,335 calls last month, and an insurance agency at about 1,000 calls a month, retained month over month.

DialSheet

A team that makes outbound calls and pays by the month. Power and 2–5 line parallel dialing in a $29 seat, no minimum; free to start.

Quo + DialSheet

An office on Quo where a few people need to dial lists. $187 a month for an office of 5 with 2 dialing, against $270 for 5 MightyCall Power users.

Quo (OpenPhone)

A small business that texts and takes calls but never dials a list. $15 a user yearly, no minimum, shared numbers and inboxes.

MightyCall

An office that wants an IVR, recording and a dialer from one vendor, three seats or more. Core from $60, Power with the dialer from $162, calling bundled.

MightyCall vs OpenPhone questions

MightyCall vs OpenPhone: which is better?

For texting and shared calls with no list dialing, OpenPhone (now Quo): $15 a user a month yearly, no seat minimum. For an IVR, call recording on every plan and a dialer in the same system, MightyCall, at $20 a user with a 3-user minimum and its dialer on Power at $54. For a team whose job is outbound calling, DialSheet beats both: a power dialer and a 2–5 line parallel dialer in a $29 seat, month to month, about $56 a month for one rep at 100 dials a day.

Is OpenPhone the same as Quo?

Yes. OpenPhone rebranded as Quo in 2025 and openphone.com redirects to quo.com. The plans are Starter $15, Business $23 and Scale $35 a user a month billed yearly ($19 / $33 / $47 monthly), one number per user, $5 for each extra, and a 7-day trial.

Does OpenPhone have a power dialer?

No. No Quo plan lists a power or auto dialer, and its fair use policy bars auto-dialers, so a team that dials lists keeps Quo for the company line and runs outbound elsewhere. DialSheet is the usual pairing: Quo Starter plus a DialSheet seat per rep is about $213 a month for three reps power-dialing 100 a day, with calls from your own Twilio numbers at ~$0.014/min.

How much does MightyCall cost compared with OpenPhone?

For one person: Quo Starter is $15 a month yearly; MightyCall's smallest bill is $60 because Core needs 3 users. For three people: Quo Starter $45, Quo Business $69, MightyCall Core $60 and MightyCall Power, the plan with the dialer, $162. Google's AI Overview prices MightyCall from $15 and Enterprise at $50; as of October 29, 2026 they are $20 and $65.

Does MightyCall have a dialer?

Yes, two plans up. Power ($54 a user yearly, 3-user minimum) adds a preview and progressive dialer, AI answering machine detection and local presence; Enterprise ($65, 5-user minimum) adds a predictive dialer at up to 10 lines per agent. Core and Pro have click-to-dial only. DialSheet puts power dialing on its free plan and a 2–5 line parallel dialer in every $29 Pro seat.

What is a good alternative to both MightyCall and OpenPhone for cold calling?

DialSheet: free for one person, with a list of up to 500 leads and 500 calls a month, then $29/month per seat with no seat minimum and no contract, with a power dialer, a 2–5 line parallel dialer, recordings and AI call summaries in the seat. One rep parallel-dialing 300 numbers a day is about $156 a month all in. It is not a phone system, so a business that needs an IVR or a shared inbox keeps MightyCall or Quo for that and adds DialSheet for the list.
