name = fields.Char(help='Tax Description', required= False)

uos_id = fields.Many2one('product.uom', string='Unit of Measure', required= False)

invoice_line_tax_id = fields.Many2many('account.tax','account_invoice_line_tax', 'invoice_line_id', 'tax_id',string='Taxes', required= False)

project_name = fields.Char(string = 'Project Name', help= 'Project_Name')

#XML:
