Hi

I have a customer who issues POs and requires the invoices to be matched. However the PO's rounding is down while pastel isn't. I can fix this with a negative amount at the bottom of my invoice but the PO also calculates the VAT based on the total amount times 0.15. It seems pastel calculates the VAT amounts per item and then adds them up a the bottom. How can I match the PO on my invoice?
