We can add a clause that allows for partial shipments as long as each shipment includes a minimum percentage of the total equipment. B: That sounds reasonable to us. Let's move on to Clause Five about payment terms. We suggest that we receive partial payment in advance, say 30% of the total cost, to cover our production costs. A: I see your point. We can add a clause that allows for partial payment in advance, but the percentage of the advance payment will be subject to negotiation between our companies. B: Agreed. I think that's all the points we need to discuss. Shall we proceed to sign the contract? A: Yes, let me make out the original copy and we can sign it together.
