Partial payments from customers

I am new to this software the most important thing I am looking for is the customer’s partial payments to a specified invoice no. so that when I make a balance sheet of a customer it should give me the details of the customer transactions like, date, amount and invoice no of payment. Is it already available or not ? if yes then where.

Refer to the Wiki article Manager Cloud under the section Using sales invoices. Simply record the partial amount received against the invoice and when the remainder is paid follow the same procedure.
