Business detective agency: Sick leave fraud (continued pay fraud)

There are endless reasons why employees are increasingly visiting the doctor and taking sick leave. Some want to increase the number of vacation days, but some employees use this “time off” for an unauthorized sideline.

Do you suspect that your employee is only feigning incapacity for work and is actually working elsewhere, possibly for your competitors?
Then get in touch with us and we can show you in a non-binding consultation what legally secure options you have to prove or refute your suspicions.

Accounting and expenses fraud, a case for our business detective agency

Are your employees always honest in their statements and expenses? Was that really a business lunch with a customer or did they treat themselves to a nice dinner with their girlfriend at company expense? As long as turnover and profit are right, there is no need for action in most cases. But as soon as your sales representatives no longer do their job properly, your company will suffer considerable damage, which is difficult for you as an entrepreneur to prove.

Whenever you suspect that your sales representatives in particular are not always behaving honestly, we will find out for you and provide reliable evidence. As a business detective agency, we are very familiar with such issues and can investigate all cases for you.

Business detectives investigate competition law

You have the feeling that a former employee is poaching your customers or your competitors are harming you with unfair competition methods? Then you need a reliable partner who can prove this for you discreetly and provably.

We investigate for you in all matters of competition law and provide you with valid evidence that can be used in court.

Theft and sabotage: Investigations by a business detective agency

Every time you take inventory, a considerable part of your goods is missing or you have the feeling that you are being deliberately sabotaged by competitors? We will look into this, whether you are being systematically robbed by your employees or thieves or we need to uncover saboteurs in your company. We help you.

We find the perpetrators and provide solid evidence so that you can take the necessary legal steps.

Working time fraud

You cannot control everything at all times. Especially on construction sites or in the field, it is almost impossible to determine whether your employees really show up for work on time and also only leave at the agreed time.

Another frequent case of working time fraud is unauthorised secondary employment, in which employees use their working time or company resources for this purpose instead of working for you, for themselves and pursuing an unauthorised secondary activity.

In this way, our business detective agency can usually determine in a very short time whether your trust is being abused or not. In this way you will receive clarity quickly and reliably. Here we can, for example, quickly provide clarity through the targeted infiltration of “new colleagues”.

Infiltration into the company with our business detectives

Sometimes it is better to infiltrate as a supposed employee. The direct proximity to your employees enables him to gather information within a very short time. In this way, especially sabotage and cases of fraud can be cleared up quickly and safely.

Our detectives can be infiltrated into all areas of the company and know how to find their way around in any environment without attracting negative attention or arousing suspicion.

Eavesdropping defence & Cybercrime: PRIMECHECK business detective agency

The modern networking of all devices in the company is practical, but also a gateway for all cyber attacks.

With sophisticated technology and expertise in the possibilities of cybercrime, we uncover all vulnerabilities for potential attackers for you and help you close security gaps before they become a problem.

We also help track down attackers and prove data espionage.
