Swipe the table sideways to see every provider.

Our figures are the software only; numbers and messages are billed by your own carrier account on top.
Competitor prices are their published list prices, checked against their own pricing pages in August 2026, on annual billing (the cheapest way to buy each). Ranges span each vendor's tiers from entry to top.
Month-to-month costs more everywhere: iPlum $13.99–30.99, Quo $19–47. Ours is $14.95 either way.
The table is narrow on purpose: it asks what several numbers cost one person, because that is the case we built for and where per-seat pricing stops making sense.
These prices move — re-check before you decide anything on them.

Line item	Us	RingCentral

Numbers are reckoned at $2 a month each, which is on the safe side — a plain local number with texting on is nearer $1.10, plus $0.40 for the caller-name lookup that shows you who is ringing.
Texts are averaged at about half a cent, including carrier surcharges.
RingCentral's figures are their published annual rates: $20, $25 or $35 per person, one number included each, $5 a month per extra number, and 25 / 100 / 200 texts per person before overage at about a cent.

Full cost breakdown →

* Business texting registration is the same money either way — about $19.50 once and $1.50 a month, payable to the carrier, passed through at cost by us and by RingCentral alike — so it's left out of both columns. Why that exists →

Competitor by competitor

What each one is genuinely good at, and where it turns.

Google Voice

Choose it if you want one extra number and don't mind whose server it lives on. It's free, and it works.

It beats us on texting, outright: unlimited US texts, free, no allowance and nothing per message.

Where it runs out

You get one number, and that's the ceiling.
It's tied to your Google account, so it can be suspended with nobody to call.
Google can read what goes through it.
Group texts cap at eight people; no international texting.
It's for personal conversation. There's no business texting registration behind it, so running a company on it goes against the product and risks quietly filtered messages.

iPlum & Quo (was OpenPhone)

Choose them if you want one number and nothing to maintain. They're the closest thing to what we do, and the two most praised in this category for being quick to set up and easy to run.

Where it turns: the second number

Both price by the seat with one number included.
Quo adds $5 a month per extra number. On iPlum an extra number is an extra line at the full plan price — from $8.99 a month, each.
Five numbers for one person: around $35/mo on Quo, around $45 on iPlum, about $23 here. Only the software is ours to charge for; each number costs about $2 from your own carrier (roughly $1.10 for the number, $0.40 for caller-name lookup, the rest light use).

How the numbers behave

On iPlum the extra lines forward into your main one, and you work out which number was dialled from the caller ID once it's already ringing. That's a reasonable design. Ours is different: each number is its own line with its own ringtone, so you know which business is calling before you decide whether to pick up — the entire reason this app exists.

RingCentral & friends

Choose them if you need call queues, desk phones on every desk, or video meetings built in. They're proper business phone systems.

Price

$20 per person per month on the entry plan, up to $35 — they've cut their prices.
One number included per person; $5 a month for each one after that.
The numbers and message history sit with them, not with you.

Texting is the part to read twice

25 texts per person per month at the $20 tier, 100 at $25, 200 at $35 — and received messages count too.
One back-and-forth with a customer can eat a month's allowance. After that it's about a cent a message, or a higher tier.
That isn't a technical limit — texts cost fractions of a cent to carry. It's where the plan is designed to push you.

Day to day

Settings are spread across several admin consoles, and finding the one you want is its own skill. That's not a knock on the engineering: one product has to serve a ten-person shop and a ten-thousand-seat call centre, and you carry that complexity either way.

RingReplacer

Choose us if you want several real numbers, you want them to be yours, and you'd rather not pay a software fee for each one.

One app that behaves like the phone's own dialler, and one settings page.
Nobody else can read your messages, and cancelling us doesn't touch your numbers — they sit in your own carrier account, a different company and a different bill.
Texting isn't rationed. No monthly allowance; you pay the carrier about half a cent a message, sent or received.
Your business registration comfortably carries a few thousand messages a month — real back-and-forth, not a handful of notifications.

The trade

You run it yourself, on a $5-a-month cloud server or a spare computer. That's the whole catch — and it's exactly why nobody else can read your messages. Sending marketing blasts to thousands of strangers? You want different software altogether.

What about 3CX?

It isn't on the chart, and not because it wouldn't do well — it would.

It's priced per system by simultaneous calls rather than per user, with a genuinely free tier for small setups, so none of the rows above can hold a meaningful figure for it.
It's a full PBX: more capable than this, and correspondingly more to run and to learn.
If you're weighing that trade, compare us against 3CX directly rather than through this table.
