Top Questions from OKmarts Buyers
Q: Does OKmarts offer volume discounts, corporate account tier pricing, or contract pricing?
A: Yes, we offer tailored B2B quotation frameworks. Procurement managers can submit a Request for Quote (RFQ) directly through the platform or contact a dedicated account manager to unlock tiered volume discounts and wholesale pricing structures.
Q: How can I verify that a product on OKmarts is brand new and not "New Old Stock" (NOS) with degraded internal components?
A: Our warehouse management system strictly tracks manufacturing date codes, especially for sensitive components like VFD electrolytic capacitors or rubber seals. We explicitly state product conditions on the listing and can provide batch date codes prior to shipment for critical applications.
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.
