Customer's Copy
In your case, the warrant has more than one copy, which is common practice. So, this 客户联 is customer's copy, which should be given to customer. 存根联 is the opposite of 客户联. 存根 means "record". 存根联 is for the vendor / service supplier / seller, depending on who is presenting the receipt.
