A Trengo alternative focused on WhatsApp sales, not tickets
Trengo is a multichannel inbox for customer service teams: email, WhatsApp, chat and social in one place, with tickets and automation. Chatdue is built for sales chats in WhatsApp: who is waiting, who needs a follow-up, what stops customers from buying.

Choose Trengo if
- You run a support team across email, chat, WhatsApp and social
- You need tickets, assignment rules and SLAs
- Your team is moving into one shared inbox
Choose Chatdue if
- Your WhatsApp is a sales channel and quotes go quiet without a follow-up
- You want to know what customers object to, not just how fast tickets close
- You want results from your existing chats without changing tools
Can you use both?
Yes, on different numbers: support in an inbox tool, sales in the WhatsApp app with Chatdue showing who to follow up with.
Chatdue connects through WhatsApp’s Linked devices feature, not the official WhatsApp Business API. That is why there is no migration and your chat history is there on day one. It also means Meta can limit such connections; we explain this in our terms.
Questions and answers
Does Chatdue handle support tickets?
No. Chatdue measures response times and unanswered chats, which helps support too, but it has no ticket system.
Which languages does the AI understand?
The AI reads conversations in the language your customers write in, and writes the suggested message in that same language.
How long is the trial?
30 days with 1 WhatsApp number, no card required.
