M.N Posted February 4, 2021 Share Posted February 4, 2021 If customer orders few hundred items with prices of some cents then invoice is created correctly with all sums and taxes as needed. However, if you make credit slip for the same order, then tax is calculated not correctly. Seems rounding problem and seems that for credit slip there is different calculation method. To solve this problem for partial or full credit there is needed either one of two solutions: A: Change rounding of the calculation for avoiding this cumulative difference in value. Where this can be done? If in DB, then how to change the field property, if in configuration then were it is defined? B: Change calculation method for taxes in credit slip. I know the files are in pdf catalogue .tpl files. Most probably needed to change is order-slip.total-tab.tpl. How to change this file to get correct credit slip? This is serious matter, as with business customers you can not say just sorry, but I refunded correct sum. Customers have full right to expect that you provide correct documentation regarding invoices and credit slips. Link to comment Share on other sites More sharing options...
