How to make the monthly statement form?

Give a simple example: for example, the monthly statement of a commodity in a supermarket, the main format is,

Last period balance unit quantity unit price amount current period sales quantity unit price amount current period balance.

This form clearly reflects the purchase, sale and storage of a commodity, which is conducive to inventory counting and customer settlement.

Your question is very general. There are dozens and hundreds of monthly reports, such as financial monthly report, total sales monthly report, monthly report of a certain variety, monthly salary report, monthly report, etc., but most of them reflect the purchase, sale and storage of the month.
