If you use IT hardware and software, then a reseller of some sort was involved in getting it to your company.

If a product originates overseas – as most of them do – then a complex supply chain is involved before it finds its way to you. Overseas vendors work with local distributors which, in turn, manage a base of resellers that do the sales and installation. If the vendor has a local office, then it’s in the vendor’s interests to work with its partners as closely as possible.
