I'm interested in understanding the full process when it comes to placing an order with your factory. Could you walk me through the steps involved, from initial inquiry to final confirmation? I'd like to know about any necessary documentation or approvals required on both sides. Also, it would be great to get an idea of the expected timelines for each stage, including production and delivery. This info will help me plan effectively on my end and ensure we're aligned in terms of expectations. Looking forward to your detailed response!
