The meter
What each platform meters on your monthly bill
The pricing meter decides your cost when message volume climbs. A platform that bills by seat or by conversation charges you more in the months when business is good.
| Product | Meters | Entry price | Grows with | A busy month |
|---|---|---|---|---|
| CommunicationOS | Connected accounts | $39/mo | The accounts you choose to connect, and nothing else | The same bill |
| Trengo | Conversations | €299/mo paid annually | 6,000 a year on Boost, 18,000 a year on Pro, then €15 to €18 per 100 | Costs more, per 100 conversations |
| Front | Seats | $25/seat/mo paid annually | $25 to $105 per seat per month, with AI sold as a further per seat add-on | Holds, until you hire someone |
| Intercom | AI resolutions | From $29/seat/mo | $0.99 per resolved outcome, charged on top of every seat | Costs more, per resolution |
| Zendesk | Agents and add-ons | $19/agent/mo paid yearly | $19 core, $55 omnichannel, $115 top tier, plus $1.50 to $2.00 per AI resolution | Costs more, per resolution |

How to spot a hidden conversation cap
Headline prices often hide usage ceilings in the fine print. Look for these six billing patterns before committing your team to an annual contract.
01
The big annual conversation pool
A pool of 18,000 yearly chats sounds generous until you divide it by twelve, which leaves 1,500 a month. Work out your own monthly volume before you sign anything.
02
The rolling conversation window
Check when a thread resets into a fresh billable event. If an existing customer replies on day eight, many platforms bill that reply as an entirely new conversation.
03
The separate AI seat surcharge
Basic seats rarely include automated writing tools. Adding an AI assistant often requires an extra $20 to $50 monthly fee on top of every single agent licence.
04
The fee per resolved outcome
Look for fees charged every time an AI bot closes a thread. A $0.99 or $1.50 outcome fee means a busy support month produces an unpredictable invoice.
05
Channel ceilings tied to plans
Starter tiers often restrict your company to one channel type or cap total inboxes at ten. You must upgrade every seat on the team just to connect another inbox.
06
The markup on third-party channels
Some shared inboxes take Meta's direct WhatsApp bill and add a 20% administration fee on top. Always verify whether messaging infrastructure carries a middleman markup.
We publish this arithmetic openly and update our figures whenever competitors change their rates. If your support desk needs deflection bots or heavy workforce scheduling, we will tell you to buy them instead.

Unlimited conversations and unlimited teammates on every plan. Your bill does not move when your month gets busy.
