Top Questions from OKmarts Buyers
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: 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: 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.
