Outsourcing platform

GRAD4 is not an intermediary, nor a supplier. The platform lets you keep full control on your outsourcing process all while making all aspects of this task easier.

All suppliers need to go through a rigorous validation process before being admitted on the platform. They also get evaluated at the end of all their contracts. This way, we make sure that we have a highly qualified and trusted network.

Success Stories

What They Say About Us

Before the GRAD4 revolution we had to manually find all the suppliers able to meet our complex needs. The most important point in my opinion is the simplicity with a few clicks of launching a tender. This formula saves time and money and finds qualified and verified suppliers. Great job to the entire GRAD4 team.

Sébastien Giguère
Managing Director at Conception BHIND

I am not done working with you. I really like your platform and the upcoming changes sound promising.

Alexandre Houle
Project manager industrial engineering, Logistics at BRP

Had we seen this before, we would have processed all our pieces that way!

Production Director at Vention

We had urgent needs. GRAD4 helped us receive a quotation very fast, and enter a contract in less than two and a half hours. It was exactly what we needed.

GRAD4 is not a supplier. Our main mission is to put the buyer and the supplier in contact quickly and efficiently. Once you enter the contract, we are no longer involved in the following steps. However, our team always remains available if you need more support with managing production or payment for example. We invite you to check out our premium service to learn more about our other services.

We recommend you watch this short video on the procedure to be follow.

You can find the various steps of the process on our product page. We also suggest you contact Marc-Antoine Bolduc, business development manager at GRAD4. He will be pleased to plan a short demo with you.
