We have been using Zoho Books for the past 6 years and are pretty happy with it.  We are looking to improve how we use Zoho in our business.  I am hoping that if I present the scenario, someone can give the direction I am hoping for.

In the USA the use of Charter Schools in our schooling system has increased.  A great portion of our business is as a vendor for the local charter schools, supplying music instruction to several students in their student base.

It's important to note that though the students are the clients of the charter school, we also consider them our client and go as far as supplying a record of available funding for them.  More on that is a bit.

This is how the business relationship works with the Charter Schools.  The student contacts us to make scheduling arrangements for their lessons.  We let the student know how much money the lessons will be, and they then notify their charter school regarding the same.  The student is then issued a "Voucher" (which for accounting purposes is a Purchase Order), from their Charter School and submits it to us.  Often, the student will submit several months worth of vouchers to us, that we keep on file.

Upon completion of the our service to the student, we invoice the Charter School, referencing the Voucher #.  The Charter school then pays us within 30 days following the invoice submission.  In the cases where we have several months of vouchers filed away for the student, we submit the corresponding month's voucher after the month of service is completed.

Here is what we want to accomplish within Zoho Books:

• Keep a record of Vouchers submitted to us which then can be invoiced to the Charter School
• Keep a seperate record for the student showing the Vouchers the student submitted to us and balance of vouchers submitted to Charter School for payment, with the ability to send reminders when don't have the Vouchers on file for amount of lessons requested.

The problem I am coming to is that if I enter the Student as a client, and the Charter School as a seperate client, we end up inputing the same voucher twice, once for the Student and once for the Charter School.  The result is a doubling 

in our income balance.

Any thoughts or ideas are much appreciated.

Thank you. :)
