Question 1

Is this a Slack-based help desk?

Accepted Answer

No. Sellio is the help desk: inbox, channels, AI agent on website chat, tickets and analytics. Slack becomes a place your team can see and answer new conversations without leaving it.

A thread per conversation. Each new chat posts once to your channel with the visitor, the page and the first message.
Sellio stays the record. Assignment, notes, tickets, ratings and analytics live in the inbox; Slack is a window onto it.
One click to connect. Add to Slack, choose the channel to notify, done.

Read about the inbox on the shared inbox page.

Question 2

Do customers join Slack?

Accepted Answer

No. Customers stay on the website widget, WhatsApp, Instagram, Telegram or email. Slack only mirrors the conversation for your team.

They never see Slack. The thread, the channel and your chatter are internal.
Replies reach them on their channel. Answer in the thread and the message goes out where they wrote from, as the agent who wrote it.
Nothing changes for the customer. They keep using the channel they already have.

How the mirror works is on the channels page.

Question 3

Which replies go to the customer?

Accepted Answer

Replies inside the conversation's thread. Messages posted in the channel itself stay internal and never reach the customer.

Thread replies go out. Each one reaches the customer on their channel, as the agent who wrote it.
Channel messages stay private. Talk about the customer in the channel without them seeing it.
The inbox works too. Reply from the Sellio inbox instead and it reaches the customer the same way.

Connecting Slack is covered in the channel guides.

Question 4

Can I use Slack and Discord or Teams at the same time?

Accepted Answer

Yes. Each new conversation opens a thread in every connected tool, and a reply in one is mirrored to the others.

The origin is never echoed back. A reply written in Slack shows in Discord and Teams, not again in Slack.
One record underneath. Whichever tool the reply came from, the Sellio inbox keeps the full conversation.
Connect each from Settings. Settings, then Integrations; approve the app and pick a channel for each tool.

See the Discord support page for the Discord setup.

Question 5

Does it cost extra?

Accepted Answer

No. Slack is included on every plan from Mini, with no add-on fee.

Priced per workspace. Plans are Free $0, Mini $45, Essentials $95 and Plus $295 a month, not per seat.
Connect it in a click. Settings, then Integrations, then Slack; approve the app and pick the channel.
Discord and Teams are included too. Connect more than one and replies are mirrored between them.

Plan details are on the pricing page.
