    >>> SaleLine = Model.get('sale.line')
    >>> sale = Sale()
    >>> sale.party = customer
    >>> sale.payment_term = payment_term

    >>> sale.untaxed_amount, sale.tax_amount, sale.total_amount
    (Decimal('29.00'), Decimal('2.90'), Decimal('31.90'))

Check cost applying::

    >>> Cost = Model.get('sale.cost')
    >>> InvoiceLine = Model.get('account.invoice.line')
    >>> invoice_cost, = [c for c in sale.costs if c.type_ == type_invoice]
    >>> lines = InvoiceLine.find([('origin', 'like', 'sale.cost,%')])
    >>> len(lines)
    0
    >>> invoice_cost.invoice_party = None
    >>> invoice_cost.save()
    >>> sale.click('confirm')
    Traceback (most recent call last):
        ...
    trytond.exceptions.UserError: Must define Invoice Party for cost of type "Invoice" on Document "1". - 
    >>> invoice_cost.invoice_party = supplier
    >>> invoice_cost.save()
    >>> bool(invoice_cost.applied)

    >>> bool(invoice_cost.appliable)

    >>> bool(Cost.find([('id', '=', invoice_cost.id), ('applied', '!=', True)]))

Create invoice and add line::

    >>> Invoice = Model.get('account.invoice')
    >>> invoice = Invoice()
    >>> invoice.party = customer
    >>> invoice.lines.append(line)
    >>> line = InvoiceLine(line.id)
    >>> invoice.save()


Delete applied costs::

    >>> sale.costs.remove(invoice_out_cost)
    >>> sale.save()
    Traceback (most recent call last):
        ...
    trytond.exceptions.UserError: Cannot unapply Cost "Invoice out @ 1" because some invoice lines are associated to invoice "(2)". - 
    >>> while invoice.lines:
    ...     _ = invoice.lines.pop()
    >>> invoice.save()
    >>> sale.save()
    >>> lines = InvoiceLine.find([('origin', '=', 'sale.cost,%s' % invoice_out_cost.id)])
    >>> len(lines)
    0
