AV brands typically supply through authorised distribution with certified integrators, and we source that way so warranty, firmware and platform certification hold.
Displays, mounts, cabling and signage panels can often be consolidated into a single import or bulk order across sites, which is where the commercial gain sits in this category.
Direct manufacturer supply is used where it is genuinely available for the category and volume. Where a brand supplies only through authorised partners, we buy that route to protect warranty and benchmark it so the difference is visible.
