our cooperation with 4B successful

Ilya Onikienko

We have been working with the law firm 4B for more than 3 years.

When launching a business on Amazon, we immediately used 4B corporation services for trademark registration, and six months later we registered the company.

One of the advantages of the company is the provision of a full range of services to support foreign companies. It includes preparation and filing of financial and tax reports according to the requirements of local tax law and control of the timely payment of taxes.
We also contacted 4B for sales tax compliance.
We got the desired result and we can confidently recommend 4B as a reliable partner for legal business support.

We evaluate our cooperation with 4B as successful and mutually beneficial. We wish 4b team professional success and prosperity.

The 4B team is highly involved to perform their tasks. They do it in the best possible way. They focus on the result, not on the process.

They always explain and justify their recommendations. I have been working with them for more than 5 years and I can say with certainty that 4B is a team of professionals who always exceeds customer expectations!

Yuriy Zdunkevich

Amazing guys! I couldn’t find specialists to unlock my Amazon account in Minsk.

As a result those who offer their services, at first they ask for a lot of money and don’t provide any guarantees.
