Top Questions from OKmarts Buyers
Q: What express logistics options are available for urgent "Factory-Down" emergency repairs?
A: We partner with premier global express couriers, including DHL, FedEx, and UPS, to provide expedited international air freight. Urgent orders are processed with priority handling at our warehouses to ensure the shortest possible transit time to your facility.
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: Does OKmarts support third-party escrow services or buyer protection payment channels?
A: Yes. For buyers seeking maximum transaction security outside traditional corporate bank wires, we support payments through verified platforms like PayPal and credit card networks that offer robust buyer dispute resolution and chargeback protection frameworks in case of fulfillment default.
