hi,


my question is, iam receiving receipts from my customers and remitted the same to bank, and i with draw the same from the bank 'A" and deposited the same amount in the bank "B" and the interest rate is 3% for a month and the maturity date is one month from the date of deposit,so here the compnany is entitled for some interest. so how do we show the above in the applications

1 Before the maturity date the system should remind me.
2. i want to see the interest that i got from the deposited amount and how it has to be show in the application & its financial impact.
3. setups needed for the above things

This is my client req


Thanks,
