1, sales records: proxy sellers can record each sale of fruit type, quantity and price. These sales records can include the date, time, location and the amount of each transaction. Owners can ask the salesperson to submit sales records to them on a regular basis, or use an online sales platform to track sales.

2. Billing: The seller should provide each buyer with a billing statement, such as a receipt or invoice. These documents should detail the quantity and price of each fruit, as well as the total sales amount. Owners can request that all settlement documents be assembled and given to them in order to verify the amount of the sale.

3, cash management: If the sale is based on cash transactions, the owner can ask the seller to hand over cash to them every day or after each sale. The owner can record the amount of cash received each time and reconcile it with sales records or settlement documents.

4. Online sales platforms: If the sale is made through an online platform, the owner can log into the platform's merchant back office and view sales reports and order details. These reports typically provide sales, order numbers and other relevant statistics.
