The basics

What is an AI late payment interest agent?

When a vendor claims interest, it checks the amount, dates and balance used and shows any difference.

Read the full explanation

It prepares a summary of interest exposure for your finance team and a draft response to the vendor.

Where it breaks

Why this step is hard by hand

Interest is a different matter from a flat fee because it grows each day and depends on the balance and period. Claims are hard to verify by hand, so they are either paid unchecked or ignored.

Rate, start date, balance, compounding and part payments all change the result.

A contract may state a rate, while local law may set a default.

Vendors may raise interest months after the delay.

Interest on a partly paid invoice runs on the remaining balance only.

Finance seldom sees how much interest the overdue list is building.

The path

How the agent does it

  1. 01Find the interest basis

    The agent reads the contract for a stated rate and method, and notes where your team applies a statutory or policy rate instead.

  2. 02List overdue items

    It identifies bills past due, with the due date, the balance outstanding and any part payments.

  3. 03Calculate the interest

    For each item it works out interest day by day on the outstanding balance, and shows the working.

  4. 04Check vendor claims

    When a claim arrives, it compares the vendor's figure with its own and highlights differences in dates, balance or rate.

  5. 05Prepare the position

    The agent drafts a summary and response for your finance team to approve, pay, negotiate or reject.

Questions

Frequently asked questions

Quick answers to what people ask most about late payment interest.

Book a demo
What is late payment interest?

It is interest a supplier may charge on an overdue invoice, running from the due date at a rate fixed by the contract or by law. It differs from a flat late fee because it grows with time.

How does the agent calculate it?

It uses the rate and method in the contract or the rule your team sets, applied to the outstanding balance over the overdue days, and shows its working.

What if the vendor's figure is different?

The agent lists where the two calculations diverge, such as dates or balance. Your team decides whether to pay, query or reject.

Does it pay interest automatically?

No. It prepares the calculation and a draft response, and finance approves any payment.
