I know the problems you can have with tax aufits. We as a ByDesign customer and some of our customers had already an audit. In all cases it worked when we explained how the logic of ByDesign is and what we can do and what we can`t.
By all audits the tax authority was fine with a customized report from Tax Management workcenter which shows all the documents (with details like net value, tax value, G/L booking number etc.) included in vat returns all over the year.
