An open-source agent that recommends from your product guide, checks stock, creates orders in your system and nudges buyers who go quiet.
Example conversationMade-up shop, products and order: blue chips are logged tool calls the customer doesn't see.
Every shop that sells by message knows these.
She asks the price, says “let me think”, and never pays. Nobody messages her again.
At 10 PM someone checks the stock sheet, then retypes the address. Late answers lose sales.
One recommends well, a new hire guesses, another offers a discount you never approved.
No buyer gets lost, even when a livestream brings 50 messages at once. The agent recommends, calls your tools, follows your playbook and hands off when needed.

Describe when the label applies, like “20+ units or a company invoice”, and turn on Triggers handoff. The agent then stops and passes the chat over.

I'd like 40 gift sets for our company's year-end party. Can you issue a VAT invoice?
Thank you! Orders that size get a quote from our team. They'll reply here.

How Ecbot guards credentials, screens messages and keeps businesses apart.
Platform tokens use AES-256-GCM with versioned keys, so keys rotate without taking channels offline.
Credentials never enter the model's context, so no prompt can pull them out.
Incoming messages are screened for scams and prompt attacks, replies for leaked data. You set the strictness.
Each business gets its own workspace. Staff join by invitation with a role, checked on every request.
Open source. Self-host it if you want.
On GitHub under AGPL-3.0, with every Cloud feature. Your knowledge stays in your own Postgres.
It answers buyers on Zalo, Messenger, WhatsApp, Telegram and your website. It recommends from your guide, checks stock, creates orders in your system, follows up on unpaid ones and hands off to your team.
