Hi,

Now i am working on purchase amount round off,i have seen one module https://www.odoo.com/apps/modules/8.0/account_invoice_rounding/

for rounding the account invoice.But in this they are adding round off value to tax for rounding the amount,when we do it journal entry will be entered in tax account.So we can't do rounding using tax.

And i have tried to change the total amount to round off but  by doing that the invoice is not changed to paid state after the payment .

Is any one know how to resolve this?

Or is there any module for rounding in odoo 8.
