Due diligence

We will help you make sure that buying business is a good deal.

One of the biggest risks involved in business acquisition is that the company is not operating in a lawful manner. Lack of mandatory permits or licences or failure to fulfil contractual obligations may result in imposing high fines on the company and even suspending its operations. Defining the scope of the seller’s liability for company condition in sales contract may – to a certain extent – protect you against such risks. If the seller’s assurances thereof prove to be false, they should be held liable.

So much for the theory. In practice, proving the falseness of representations is not easy and it may turn out that a possible dispute will have to be submitted for settlement to a court. This means it may drag on for several years and no one will guarantee that even after it is finally and firmly resolved you will obtain a favourable judgement. Therefore, in addition to defining the scope of the seller’s liability for company condition in the contract, it is advisable to evaluate target company or its assets before acquisition. If you decide to use our services, we will be your partner to make sure the company acquisition transaction is not only safe but also in our best interests.

How can we help you?

For many years we have been working with company owners who either plan to buy business or are in the process of buying it. Most of them pay careful attention to target company evaluation prior to signing a contract. Hence, we provide support throughout the entire due diligence procedure.

Lowering the sale price

Potential risks on the part of the buyer might adversely affect the company selling price. If we conduct due diligence investigation and identify such risks, you will be able to use them to your advantage in order to lower the price.

With due diligence report, you will be able to, as the company new owner, remove irregularities found during due diligence procedure.

Increasing liability

The results of due diligence investigation may be used to increase the seller’s liability for the company. For example: identifying irregularities in the payment of social security contributions may result in extending the period of liability of the seller for defects found in the course of possible inspections by the Social Insurance Institution (ZUS).

Removing irregularities

With due diligence report, you will be able to, as the company new owner, remove irregularities found during due diligence procedure. We will advise you on how to safely perform this type of investigation.

‘We are always personally involved in each due diligence we conduct. Such an investigation is too serious and unconventional issue to be entrusted to someone less competent. Your request is always a priority to us, and for that reason we will devote to it the maximum of our attention and commitment.’
