    Top Questions from OKmarts Buyers

    • 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.

    • Q: Does OKmarts maintain a historical record of my purchases for future asset management or auditing?

      A: Yes. Your corporate dashboard retains a permanent, secure repository of all past transactions, technical specifications, commercial invoices, and warranty dates. This allows your maintenance, repair, and operations (MRO) teams to instantly pull historical records for equipment auditing or one-click reordering of consumable parts.

    • 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.
