印度采购需求：电动三轮车，载客三轮车

I'm interested in purchasing an electric toilet and would like to know more about the pricing options you have available. Could you provide details on the different models you offer, along with their specifications? I'm particularly curious about features like water efficiency, ease of installation, and any smart functionalities that might be included. Additionally, I'd appreciate information on the ordering process. What are the payment terms, and how long does shipping typically take? Do you offer support or installation services after the purchase? Looking forward to your prompt response so we can move forward with this potential order.
