Top Questions from OKmarts Buyers
Q: Does the OKmarts platform support Bill of Materials (BOM) uploading for rapid mass quoting?
A: Yes. Procurement teams do not need to search for individual parts manually. You can upload an Excel/CSV file containing your complete Bill of Materials (BOM) with part numbers, quantities, and brands. Our automated processing engine, backed by data engineers, will generate a comprehensive consolidated quote within 24 hours.
Q: Can I request a live video inspection of my specific order items before they leave the OKmarts facility?
A: Yes. To maximize peace of mind for high-value or critical orders, buyers can request a "Pre-Shipment Video Verification." Our warehouse team will film the unboxing, display the original manufacturer seals, show matching serial numbers, and verify the physical condition of the components in real-time or via a high-definition video link.
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.
