Commercial and Contract Specialists as Your Business Consultants

Introducing best practices in your company or finding business consultants or employees with the right skills and experience to generate leads, write proposals, draft, negotiate and manage contracts is not easy and often time-consuming.

Without multi-skilled and highly experienced commercial professionals and contract experts, it is impossible to optimize your top and bottom lines.

Such people are hard to find. Within your company or outside. For full-time positions or on project-base.

This is especially a challenge for manufacturing and engineering companies and suppliers selling or procuring high-value complex products and services through long-term contracts.

Like in the aerospace, defense, aviation, IT and high-tech manufacturing industries we have worked for, or are still working for.

Organizations we have worked for in then past 30 years

That’s why we have set up ContractExec. To bring together out business consultants, commercial and contract professionals, specialists and companies, suppliers, and organizations in need of such people and skills.
