A: No. Unlike surplus liquidation brokers who sell unpredictable, unvetted excess inventory, OKmarts builds strategic partnerships directly with active factory supply chains and authorized distribution channels. This ensures that every component is fully traceable, factory-fresh, and covered by standard manufacturer liability frameworks.
A: Hardware units ship with standard factory-default firmware. For proprietary programming software or specific firmware flashes required for legacy system compatibility, buyers must consult our technical support team during procurement to confirm licensing terms.
A: OKmarts operates under a legally registered corporate entity with verifiable business registration records, global tax compliance IDs, and physical warehouse infrastructure. We can provide corporate bank references, Dunn & Bradstreet (D-U-N-S) numbers, and customer references from established industrial firms in your region to validate our commercial legitimacy before you transfer funds.
