PAYPAL - ICICI BANK - ZOHO BOOKS

PAYPAL - ICICI BANK - ZOHO BOOKS

Hi, I am new to ZOHO domain. 
Status:
1) I have integrated Zoho with my bank account which is ICICI
2) I receive my payment through Paypal/Razor Pay
3) I have not linked Paypal account with Zoho Books.
4) My Paypal account is linked with ICICI Bank
5) I receive in different currencies
6)  Paypal receives USD 100 and deducts it commission say USD 3 and credits the balance USD 97 to my Bank account. 

My query:-
1)  How do we account for the fees deducted by Paypal in Zoho books
2) If I integrate Zoho books with Paytm in addition to the already linked Paytm with my Bank, Will there be duplication?

I would like to have assistance on this.
