Top Questions from OKmarts Buyers
Q: Can OKmarts issue formalized, compliant proforma invoices and commercial invoices tailored for corporate accounting?
A: Absolutely. Our automated billing system generates itemized Proforma Invoices (PI) and Commercial Invoices containing corporate tax IDs, purchase order (PO) numbers, and explicit company details necessary to satisfy international corporate accounting and auditing standards.
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: 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.
