Top Questions from OKmarts Buyers
Q: Can my organization create a dedicated corporate account with multi-user permissions for different procurement roles?
A: Yes. Our platform supports corporate account provisioning. A master account can be set up for a Procurement Director, with sub-accounts granted to field engineers (for creating technical carts) and purchasing agents (for executing payments), streamlining internal corporate approval workflows.
Q: How can a first-time international buyer verify that OKmarts is a legitimate entity and not a fraudulent website?
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.
Q: How can I track my shipment's exact location, customs milestones, and estimated delivery hour?
A: Immediately upon dispatch, the platform automatically generates an international tracking link integrated with carriers like DHL, FedEx, or UPS. Real-time API tracking is accessible directly from your OKmarts account dashboard, displaying live transit status, customs clearance progression, and finalized delivery updates.
