please help me in maintaining a/c

hi all,

actually i am having problem in maintaining accounts of a agrobase company.

This company sells vegetables to their memebers. The basic flow of operation of this company is as such> first they invite clients to become their members.They charge memebership fees for this.>with membership fees they collect coupon chrges for one month and issue coupon > daily they send fresh vegetables to members residence and collects a coupon form the members for the vegetables and cancels it.

I am facing problem that how i should maintain that coupon and how would i take entry in tally? Should i prepare excel sheet then enter it in tally? How?

Plz solve my problem.
