Connect Claude & ChatGPT to Likvido

Ask your AI which invoices are still open in Likvido, what has happened on a case, or whether a debtor has paid. It can search debtors and invoices, read an invoice's timeline and payments, and get the payment link. It can also create debtors and invoices for collection, pause or resume collection and register payments.

Try asking

“Which invoices for Nordic Foods ApS are still open?”
The AI searches for the debtor, then lists their invoices with amounts, due dates and collection state.
“What has happened on invoice 4821 so far?”
It reads the invoice's timeline: reminders sent, payments and state changes.
“Which payments came in last week?”
It lists payments across all invoices for that date range.

What your AI can do

Debtors and invoices

Search, read and create debtors, and search, read and create invoices for collection, with lines, currency and references.

Collection control

Pause and resume collection on an invoice, or close it so Likvido stops collecting, with an optional note to the debtor.

Payments and history

List payments across invoices or on one invoice, register payments, and read each invoice's timeline, files and payment link.

“Pause collection on invoice 4821 until the 1st, the customer has called.”
It pauses the invoice until that date with your note, so no further reminders go out.
“Send me the payment link for invoice 4821.”
It gets the debtor-facing payment link, which you can pass on so the debtor can pay online.
“The customer paid 2,500 DKK by bank transfer yesterday. Register it on invoice 4821.”
It registers the payment with amount and date. This records the payment in Likvido and does not move money.

Questions

What can the AI do in Likvido?

It can search and read debtors and invoices, read an invoice's timeline, files, payments and payment link, and list payments across invoices. It can create debtors and invoices, pause, resume and close collection on an invoice, and register payments.

Does the AI see my Likvido credentials?

No. Your Likvido API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with lookups only. Creating an invoice starts collection, which can contact the debtor, and closing an invoice is hard to undo. Actions like these can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Likvido account.

Does registering a payment move money?

No. Registering a payment only records in Likvido that the debtor has paid, with amount and date. You can choose to close the case at the same time and to notify the debtor.
