Top Questions from OKmarts Buyers
Q: Are software licenses, firmware updates, and configuration files included with hardware like HMIs and PLCs?
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.
Q: What secure payment methods are supported for high-value international B2B transactions?
A: To ensure transaction security and accommodate standard corporate purchasing workflows, we support secure international Telegraphic Transfers (T/T Wire), major corporate Credit Cards, PayPal, and Letter of Credit (L/C) frameworks for large-scale procurement contracts.
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.
