Connect ChatGPT to your data

Ask questions about your sales from your own ChatGPT. Connect it from the Marketplace, add the link in ChatGPT's developer mode, and switch it off any time.

If you use ChatGPT, you can connect it to your sales data so it can answer questions about your business. Tillable gives you a private link to add in ChatGPT. There is no separate password or token to fill in.

For the chat built into Tillable, see AI Reporting. To use Claude instead, see Connect Claude to your data.

Both read the same reports, so anything the in-portal chat can answer, your own ChatGPT can answer too. The full list of what you can ask is in AI Reporting.

Check your ChatGPT plan first

Note

ChatGPT adds a link like this as a custom connector in developer mode, on the web only (not the mobile app). Full custom connectors are available on ChatGPT Business, Enterprise and Edu. Pro can use read/fetch connectors in developer mode. On a Business, Enterprise or Edu workspace, an admin may need to switch developer mode on for you first. Check with OpenAI for your plan.

Where to find it

In the sidebar, open Marketplace → Discover and press the ChatGPT card. The ChatGPT page has two tabs: Overview (what it does and how to set it up) and Connection (your links).

Only the account owner or an admin can connect ChatGPT. Everyone else sees the page and its links read-only, with the line "Ask your account owner to connect ChatGPT."

Connect and add the link

1
Press Connect ChatGPT
On the ChatGPT page, press Connect ChatGPT. Tillable makes a private link for your venue and opens the Connection tab.
2
Copy it now
The link is shown once. Press Copy link straight away. For security it is never shown again. If you lose it, press New link to make another.
3
Turn on developer mode in ChatGPT
In ChatGPT on the web, open Settings → Security and login and turn on Developer mode.
4
Add the link
Go to Plugins in ChatGPT and press the + button. Give it a name (for example Tillable) and a short description, and paste your link as the MCP server URL. If ChatGPT asks about authentication, choose No authentication: the link carries its own key. Create it, and ChatGPT lists the reports it can read.
5
Ask away
Start a new chat, choose Developer mode from the + menu and pick your Tillable connector. Then ask about your venue.

ChatGPT's own menus can change. If a step does not match what you see, follow OpenAI's help page, Developer mode and MCP apps in ChatGPT.

Connected or Link ready?

The ChatGPT page, and the ChatGPT card on the Marketplace, show one of three things:

Not connected: you have no ChatGPT link.
Link ready — not used yet: you have made a link, but ChatGPT has not asked anything with it yet. If you have added it in ChatGPT and still see this, ask ChatGPT a question about your venue: it changes on the first answer.
Connected · last used …: ChatGPT has used your link to read your reports, and this is when it last did.

Your ChatGPT and Claude links are separate. Connecting one never makes the other say Connected.

You do not need to reload the page after connecting: it changes to Link ready on its own.

Figures in pounds

Links made from the Marketplace end in &units=gbp, and ChatGPT is given every amount in pounds.

Keep the link safe

Heads up

The link works like a password. Anyone with it can read your sales data. If you think it has been shared by mistake, revoke it on the Connection tab and make a new one. The link is read-only: it can never change your menu, prices, bills or payments.

No daily limit on the connector

The in-portal chat has a shared allowance of 50 assistant questions a day (see AI Reporting). Asking from your own ChatGPT through a connector link does not come out of it. You are using your own ChatGPT subscription.

Let it suggest changes (30 days)

On some accounts the Connection tab also shows Let it suggest changes (30 days). Press Make a suggest link and add that link to ChatGPT the same way. With it, ChatGPT can suggest a change — a new discount, a renamed category, a fact to remember — as well as answer questions.

Nothing changes until you approve it. Each suggestion comes back as an approval link. Open it in Tillable to see exactly what would change, then approve or reject it.
It stops working after 30 days. Make a new one if you still want it.
Revoke it on the Connection tab like any other link.

If you do not see the option, your account is not set up for it yet.

Managing and revoking access

The Connection tab lists your ChatGPT links, when each was made and when it was last used. Press Revoke on any you no longer need: that link stops working straight away. Disconnect at the top of the page revokes every ChatGPT link at once. You can also remove the connector in ChatGPT, but only revoking it here stops the link itself working.

Owners and admins also see Other access links, folded shut under the list. These are older access links, usually left behind by the in-portal chat, that can still read your reports. Revoke any you do not recognise.
