After using the credit charges wizard, how can you see which credit charge is for which invoice? I can't seem to find an automatic way of these charges showing which invoices they arise from. I have to manually sit and calculate each credit charge and count the number of days to determine which late payment charge is allocated to which invoice. Is there an easier way around this? Or what's the best way to apply late charges if your terms are - base rate + interest rate x no of days of overdue invoice?
