Top Questions from OKmarts Buyers
Q: How are long-term component supply risks handled if our factory relies heavily on a specific part sourced from your platform?
A: We offer supply chain buffering and safety stock agreements for industrial clients. By sharing your annual procurement forecast, we can pre-allocate inventory in our warehouses to guarantee a continuous, predictable supply and protect your production lines from market shortages.
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: Is there a warranty provided on industrial parts, and how is the RMA (Return Merchandise Authorization) process handled?
A: All new and original industrial parts carry a standard 12-month factory warranty. If a component fails or shows defects within the warranty period, buyers can initiate an RMA request through our platform, which prompts our team to coordinate testing, repair, or replacement directly with the manufacturer.
