Fraud detection

mika warns you about fake invoices.

You send invoices to mika as soon as they arrive: through Gmail, a scan, an upload or by forwarding them. If one looks like fraud, mika warns you shortly after, which means before you pay: right at the top of your task list and by email.

Recreated todo list of your agency in mika: a Kostenrechnung, a German bill for fees, for €892.50 with a Spanish IBAN goes to mika via Upload. Shortly after, the Possible fraud todo sits at the top under Pinned, with three reasons and the advice not to pay yet. An email follows with the subject Possible fraud: check this invoice before you pay it.

First the warning. Then you decide.

More than 900 companies rely on mika

An example

A letter that looks like it comes from the Handelsregister.

Letters like this arrive after you set up your company and after changes in the Handelsregister, the German commercial register. For your agency, it's the move to new offices: a few days after the new entry, a Kostenrechnung, a bill for fees, arrives in the post.

  1. Mira, your office manager, scans the letter.

    The sender is a “Zentralstelle für Registereintragungen GmbH”, which sounds like a central registry office. The letter demands €892.50, payable within three working days. She sends the scan to mika, like any other receipt.

  2. Shortly after, the warning sits right at the top in mika.

    It's a todo, an open task in mika, called “Possible fraud”.

  3. mika tells you why.

    The todo gives one sentence for each sign. The IBAN is Spanish, but a German register court, the court that keeps the Handelsregister, only uses German accounts. The name sounds like an authority, but the sender is a private GmbH, a German limited company. Below that is the advice: don't pay yet, and check with the sender through a contact you already know.

  4. You get an email.

    You click “Check the invoice in mika” and you're in the todo. You don't pay. The €892.50 stays where it is.

Fraud detection

This letter is just one of many scams.

Another example: your supplier sends its invoice as usual, but the IBAN suddenly points to an account abroad. mika warns you then too. To do this, mika uses AI to read the whole text of the invoice and compares it with the sender's earlier invoices and with known fraud patterns, a collection that keeps growing.

In 15 minutes you'll see what mika does with every invoice that reaches you.

Questions about fake invoices

What's in the Handelsregister, the German commercial register, is public: company name, address, managing directors. So shortly after you set up your company or change an entry, letters arrive that look like a bill for fees from the court. The deadline is short, a dunning fee is threatened, and the account doesn't belong to the courts. mika knows this scam. If you send a letter like that to mika as soon as it arrives, mika warns you shortly after, which means before you pay.

mika reads every invoice in full: sender, address, IBAN, amount, deadlines and text. Then mika compares it with a collection of fraud patterns that keeps growing, and with the invoices the same supplier has sent you before. If mika finds signs of fraud, the todo tells you what doesn't fit, one sentence per sign.

The todo tells you what you can do now: don't pay the invoice yet, and check with the sender through a contact you already know. For example, the phone number on the official website of the court or supplier, not the details on the invoice itself. Whether you pay is your decision.

In the todo, click “Overrule” to dismiss the warning and add a short note on why. The warning is done, and mika won't warn you about this invoice again.

No. Fraud detection is on for every company in mika.

Send your invoices to mika as soon as they arrive. mika keeps an eye on them.
