I have been trying for several months to get ths issue resoved, with no success. It affects every client in Canada, (and possibly other VAT countries). If they use early payment discounts, their sales taxes will not be correct, and they will have to be manually adjusted or subject to fines from the government. Most clients are probably not aware of this deficiency. It seems to me that accounting is one of the things that we have to get right and should be considered a priority. Thanks for your attention.
