Billed once a year: $390 Starter, $790 Team, $4,990 Scale. The figures above are that total divided by twelve, rounded to the nearest dollar.
A connected account is a single WhatsApp SIM, mailbox, Telegram login or Signal number. It is not an employee seat. Connect two WhatsApp numbers on Starter and invite thirty teammates to work them at the same time.
An add-on attaches to an active subscription and prorates across the billing cycle.
A small software agency
$39
Four people sharing two WhatsApp lines and one shared client mailbox.
A regional support desk
$79
Fifteen staff on five WhatsApp lines, two Telegram channels and three regional mailboxes.
A freight operation, three countries
$499

Read from each vendor’s public pricing page in 24 August 2026, priced for a team of 15 people and 12,000 conversations a year. Each vendor name links to the page the figures came from. Each price is quoted in the currency its vendor publishes. Trengo publishes in euros and we publish in US dollars. We do not convert between the two. Trengo's figures were read on 24 August 2026.
What counts as a connected account?
One active external channel. One WhatsApp SIM, one Telegram login, one IMAP mailbox. The teammates reading and replying through those accounts do not count against the limit.
What happens if I go over my indexed storage?
You get a notice at 80% of the allowance and again at 95%. Incoming messages keep arriving and stored history stays in place. Move up a plan, or add a 50 GB block for $15 a month.
Do you charge per message or per user?
No. There is no per-message fee, no per-conversation fee and no seat fee. Messages and teammates carry no separate fee. Indexed-storage overage can still change the invoice.
Can I change plan mid-month?
Yes. Upgrades apply immediately and are prorated. Downgrades take effect at the end of the current period, so you keep the higher limits until then.
Is there a free trial?
Fourteen days on Team, with the AI suite, history search and the live channels. No card needed to start.
What does the annual discount work out to?
Twelve months for the price of ten. The annual invoice is $390 for Starter, $790 for Team and $4,990 for Scale, billed once up front. The monthly figures on the cards are that total divided by twelve, rounded to the nearest dollar.
What happens to my history if I cancel?
Read and export access stays open for 30 days after cancellation. We delete live data within 7 days after that, and purge backups within 14 days of the deletion. Export formats are JSON, MBOX, HTML, CSV and PDF, plus the original media.
Where is message data stored?
Message data is stored in the European Union by default. Enterprise contracts can pin a different region.
Who can see that a message was read or exported?
Each read and export is written to the audit log. Customer access to the log starts on the Team plan.
Fourteen days on Team, no card. Upload a network archive or migrate a supported shared inbox while you are still deciding.
