Comment 8 for bug 868839

One thing I wanted to stress importance on, I do not understand the tax calculation method in OpenERP. It does not make sense to me. In almost ANY program I can configure an actual percentage like 7.275, 15% and so on. But in OpenERP I have to use a ratio 0-1? like 0.0275 or something similar. The problem ends up is that the tax calculation is not the same.

When using an external order system I have to match exactly the amounts in the external system with OpenERP. Because the taxes have to be calculated independently in OpenERP it appears impossible to have a match. I find in all cases there is a rounding discrepancy and the higher the amount of the sale the higher the discrepancy.

This end result makes auto-reconciliation of sale order impossible. One of pythons great features is decimal accuracy, so I am surprised to have such an issue.

I also agree with mike in the fact you do not have a standard built in configurable option for taxes. Things like this are industry standard and you should not have to make any modification. Just like when you create a new database and it selects euro as the currency silently. You really need to work on these things, its so simple and so asinine to have these problems in an "enterprise" software
