GeM (Government e-Marketplace) lets government departments buy AV equipment from approved vendors without going through a full tender for most categories.
What matters when choosing a GeM AV supplier: registered status (verify the seller ID), local presence for installation and warranty support, and authorised dealership for the brand you're buying. A box on GeM with no local install partner is a waste of budget.
Yash Engineering Sales is GeM-registered for major AV categories with full Central India install and warranty cover.
