Top Questions from OKmarts Buyers
Q: How are long-term component supply risks handled if our factory relies heavily on a specific part sourced from your platform?
A: We offer supply chain buffering and safety stock agreements for industrial clients. By sharing your annual procurement forecast, we can pre-allocate inventory in our warehouses to guarantee a continuous, predictable supply and protect your production lines from market shortages.
Q: Can OKmarts issue formalized, compliant proforma invoices and commercial invoices tailored for corporate accounting?
A: Absolutely. Our automated billing system generates itemized Proforma Invoices (PI) and Commercial Invoices containing corporate tax IDs, purchase order (PO) numbers, and explicit company details necessary to satisfy international corporate accounting and auditing standards.
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.
