Connect Claude & ChatGPT to Chaser

Ask your AI which invoices are overdue, what Chaser has already sent a customer, or to pause reminders while a dispute is sorted out. It can read and update customers, contact persons and invoices, list credit notes, put customers on chasing schedules, and keep notes and tasks up to date. Your credit control questions get answered without clicking through each customer.

Try asking

“Which invoices are more than 30 days overdue?”
The AI lists invoices filtered by status and due date, with customer and amount due.
“What reminders has Chaser sent for invoice 1043?”
It reads the invoice's chasing history: reminders sent and other events.
“Pause chasing for Nordic Foods while we sort out their complaint.”
It finds the customer and pauses reminders for all of their invoices. Chasing can be resumed later.

What your AI can do

Invoices and credit notes

List and filter invoices by status, dates and amounts, read chasing history, add and update invoices, and list credit notes.

Chasing control

Pause and resume chasing for one invoice or a whole customer, list schedules and put customers on a schedule.

Customers, notes and tasks

Create and update customers and contact persons, add notes, and create and update follow-up tasks.

“Put these three customers on our strict schedule.”
It lists your chasing schedules and assigns the customers. Reminders are then sent on that schedule.
“Note that Acme promised to pay on Friday, and remind me to follow up.”
It adds a note to the customer and creates a follow-up task with a due date.
“Invoice 1043 was part-paid with 5,000. Update it.”
It updates the invoice's amount paid and amount due.

Questions

What can the AI do in Chaser?

The AI can read your organisation, customers, contact persons, notes, invoices, invoice chasing history, credit notes, schedules and tasks. It can create and update customers, contact persons, invoices and tasks, add notes, pause and resume chasing, and put customers on a chasing schedule.

Does the AI see my Chaser credentials?

No. Your Chaser API key and API secret are encrypted at rest and never shown to the AI. After you save them, they are 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 read-only. Actions that lead to reminders being sent, like putting customers on a schedule or adding invoices, 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 Chaser account.

Can the AI stop reminders for a customer?

Yes. It can pause chasing for a single invoice or for all of a customer's invoices, and resume it again later. It can also read an invoice's chasing history, so you can see what has already been sent before you decide.
