Top Questions from OKmarts Buyers
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: What financial protections do I have if the shipped goods do not match the ordered part numbers or technical specifications?
A: OKmarts operates under a strict Order Accuracy Guarantee. If the part numbers delivered do not match your approved Proforma Invoice or Purchase Order due to our fulfillment error, we will issue a full refund or expedite a replacement shipment immediately, covering all return international freight charges.
Q: Can OKmarts assist in verifying technical compatibility before I place a high-value order?
A: Yes. Buyers can upload existing equipment nameplates, system schematics, or parameter requirements. Our applications engineers will cross-verify physical dimensions, electrical ratings, and communication protocols (e.g., Profinet, EtherCAT) before finalizing the order.
