Top Questions from OKmarts Buyers
Q: Can my organization create a dedicated corporate account with multi-user permissions for different procurement roles?
A: Yes. Our platform supports corporate account provisioning. A master account can be set up for a Procurement Director, with sub-accounts granted to field engineers (for creating technical carts) and purchasing agents (for executing payments), streamlining internal corporate approval workflows.
Q: Can OKmarts provide specialized industrial packaging for sea freight or long-term tropical storage?
A: Yes. For international shipping or extended warehouse storage in high-humidity regions, we offer upgraded industrial packaging options. This includes vacuum-sealed anti-static (ESD) barriers, desiccant packs, heavy-duty wooden crates, and shock-absorbent padding tailored to withstand harsh maritime transit conditions.
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.
