Hello,

You can set decimal precision by going to Configuration -> DB Structure -> Decimal precision.

Set Product Price to : 3

Also, in the Point Of Sale, if you want orders to have decimal precision set to 3, you have to add one entry in Configuration -> DB Structure -> Decimal precision

Create a new one and type "Point Of Sale" (without commas), and set it to 3 digits.

This is because in point_of_sale.py, some columns try to retrieve decimal precision from decimal.precision model, looking for "Point Of Sale" , but no entry has been set for this.

See in point_of_sale.py, in pos_order class :

dp.get_precision('Point Of Sale')

About decimal precision, see on top of file :

import openerp.addons.decimal_precision as dp

It seems that OpenERP Team forgot this step.

Best regards
