Top Questions from OKmarts Buyers
Q: Can we request customized modifications for heavy wear components or specialized industrial parts?
A: Through our network of partner factories and flexible manufacturing technologies, we support customized production runs for specific structural or wear components. Technical drawings (CAD/STEP files) must be submitted for engineering review and custom prototyping quotes.
Q: What should I do if the specific part number is obsolete or discontinued by the manufacturer?
A: Our technical engineering team specializes in obsolescence management. If a part is lifecycle-discontinued, we utilize our cross-reference database to recommend exact drop-in replacements or functionally equivalent alternatives, ensuring minimal redesign for your machinery.
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.
