Top Questions from OKmarts Buyers
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: Does OKmarts maintain a historical record of my purchases for future asset management or auditing?
A: Yes. Your corporate dashboard retains a permanent, secure repository of all past transactions, technical specifications, commercial invoices, and warranty dates. This allows your maintenance, repair, and operations (MRO) teams to instantly pull historical records for equipment auditing or one-click reordering of consumable parts.
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.
