The payment will be registered when the POS session is closed. Anyway, the associated invoice will remain open. This last, definitely is a bug, I did not find a way to reconcile, or associate the payment to the invoice yet.

I'll see what happen if I change de invoice status in some way.

I have the same issue , i find this: https://github.com/odoo/odoo/issues/6534

I make same change to work for odoo 9:

from openerp.osv import fields, osvimport logging_logger = logging.getLogger(__name__) class pos_session(osv.osv): _inherit = 'pos.session' def _confirm_orders(self, cr, uid, ids, context=None): account_move_obj = self.pool.get('account.move') account_move_line_obj = self.pool.get('account.move.line') pos_order_obj = self.pool.get('pos.order') for session in self.browse(cr, uid, ids, context=context): local_context = dict(context or {}, force_company=session.config_id.journal_id.company_id.id) order_ids = [order.id for order in session.order_ids if order.state == 'paid'] move_id = account_move_obj.create(cr, uid, {'ref' : session.name, 'journal_id' : session.config_id.journal_id.id, }, context=local_context) pos_order_obj._create_account_move_line(cr, uid, order_ids, session, move_id, context=local_context) for order in session.order_ids: if order.state == 'done': continue if order.state not in ('paid', 'invoiced'): raise osv.except_osv( _('Error!'), _("You cannot confirm all orders of this session, because they have not the 'paid' status")) else: pos_order_obj.signal_workflow(cr, uid, [order.id], 'done') order_ids = self.pool.get('pos.order').search(cr, uid, [('session_id','=', session.id)]) for obj_order_id in self.pool.get('pos.order').browse(cr, uid, order_ids, context=context): move_line = [] for move_line_id in obj_order_id.invoice_id.move_id.line_ids: if move_line_id.name == obj_order_id.name: move_line.append(move_line_id.id) move_line_ids_1 = [] for statement_id in obj_order_id.statement_ids: move_line_ids = account_move_line_obj.search(cr, uid, [('statement_id','=', statement_id.statement_id and statement_id.statement_id.id)]) if (move_line_ids != move_line_ids_1) : for line in account_move_line_obj.browse(cr, uid, move_line_ids): if line.credit and line.name.strip().strip(':') == obj_order_id.name: move_line.append(line.id) if line.debit and 'return' in line.name: move_line.append(line.id) move_line_ids_1 = move_line_ids ctx = context.copy() ctx.update({'active_ids': move_line}) self.pool.get('account.move.line.reconcile').trans_rec_reconcile_full(cr, uid, [], ctx) return True 

The invoice change from Open to Paid only after closed the session of the Point Of Sale.

Just in case that there are people looking for a fix, here is a simple module that will auto reconcile the invoice with its payment so the invoice will be paid.

Hi \Alejandro Perez Cosio

1)In POS, if any order is invoiced then you can check under POS Orders and you will find that particular order status as “Invoiced”.

Note :- Even if the session in which the Invoice was generated is validated and closed the invoice status does not change. This needs a relook.

2)But If you click on the POS Order and go to the Tab “Extra Info” , you will be able to find a field Invoice(e.g. SAJ/2016/0003Main/007) associated with the POS Order under Accounting Information. On clicking on it you will have the option to register payment.

Hope this helps

Cheers

I have the same issue, did you find a solution?
