Customer Overdue Tolerance

Hi experts

How to set tolerance for customer overdue for fractional overdue value

due to this fractional overdue system not allowing to book further orders to the credit customers

for example

customer having overdue Rs 1000.01

Receipt Value is Rs 1000.00

Rs0.01 fractional balance is lying in customer account and system will not allow book orders until clearing overdue

Please suggest if anybody knows option to avoid such type of issue and run sooth business with customer

Thanks
