I am inputting my suppliers receipt into Manager’s Purchase Invoice.
The order has a 15% discount on all items except shipping and a sales tax of 15% on all items including shipping.
There is a $0.06 difference in the discount calculated resulting in a $0.06 difference in the total
Below is the calculation from the supplier.

Below is the calculation from Manager’s Purchase Invoice. I’ve edited out the items for privacy.
I think the difference in calculation comes from the method of calculation of my supplier and manager. The supplier calculates 15% from the subtotal resulting in a discount of $143.18. Manager applies the 15% discount per item and due to rounding, there is a $0.06 difference resulting in a discount of $143.24.
How can I correct this discrepancy so the record in Manager matches that of my supplier?
