AeroChat suits an online store that wants customers to ask, pay and get delivery updates in one conversation, on WhatsApp, Instagram, Messenger, Telegram, TikTok Shop buyer chat, web chat and email, with no surcharge on each AI conversation.

Where AeroChat is different
No surcharge on each AI conversation
Trengo charges €0.25 to €0.30 for each AI-handled conversation on top of the plan. AeroChat plans are sized by AI responses, and your team’s replies never use the allowance.
It finishes the sale in the chat
When a customer says “I’ll take it”, AeroChat sends an Airwallex payment link, detects the payment and confirms the order in the same conversation. In Malaysia it books the delivery with POS Malaysia.
Order questions answered from the store
AeroChat verifies the customer’s email or phone, then reads the order from your Shopify store and answers where it is, what is in it and when it ships. Orders are never stored. It also answers product, stock and shipping questions from the same store data, so the conversation does not end at a notification.
Describe a workflow and it is built
Instead of drawing a flow, you describe what you want in your own words, for example “when a customer asks where their order is, verify their email, check the order and send the tracking link”, paste in the key of the system you are connecting, and AeroChat builds it. No code needed. Any system with a public API connects this way. See the integrations it already has pages for.
When Trengo may suit you better
- You need voice in the same inbox. Trengo sells voice as an add-on. AeroChat works in text channels.
- Your team works mostly in a shared inbox. If people answer most chats and AI is a helper, Trengo’s inbox, routing and reports are built for that.

Switching from Trengo to AeroChat

- Bring your knowledge across. Add your policies, FAQs and pages so the answers match what your customers already get.
- Describe your workflows. Order status, returns, bookings and taking payment in the chat. AeroChat builds each one from your description.
- Recreate your approved templates. Business-initiated WhatsApp messages outside the 24-hour window need approved templates. See WhatsApp message templates.
