+Imports::
+
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model
+    >>> from trytond.modules.account.tests.tools import create_chart, get_accounts
+    >>> from trytond.modules.company.tests.tools import create_company
+    >>> from trytond.tests.tools import activate_modules
+
+Activate modules::
+
+    >>> config = activate_modules('sale', create_company, create_chart)
+
+    >>> Party = Model.get('party.party')
+    >>> ProductCategory = Model.get('product.category')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> ProductUom = Model.get('product.uom')
+    >>> Sale = Model.get('sale.sale')
+
+Get accounts::
+
+    >>> accounts = get_accounts()
+
+Create party::
+
+    >>> customer = Party(name="Customer")
+    >>> customer.save()
+
+Create account category::
+
+    >>> account_category = ProductCategory(name="Account Category")
+    >>> account_category.accounting = True
+    >>> account_category.account_revenue = accounts['revenue']
+    >>> account_category.save()
+
+Create product::
+
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
+
+    >>> template = ProductTemplate()
+    >>> template.name = 'product'
+    >>> template.default_uom = unit
+    >>> template.type = 'service'
+    >>> template.salable = True
+    >>> template.account_category = account_category
+    >>> template.list_price = Decimal('10')
+    >>> template.save()
+    >>> product, = template.products
+
+Sale with manual invoice method::
+
+    >>> sale = Sale()
+    >>> sale.party = customer
+    >>> sale.invoice_method = 'manual'
+    >>> line = sale.lines.new()
+    >>> line.product = product
+    >>> line.quantity = 10
+    >>> sale.click('quote')
+    >>> sale.click('confirm')
+    >>> sale.state
+    'processing'
+    >>> sale.invoice_state
+    'none'
+    >>> len(sale.invoices)
+    0
+
+Manually create an invoice::
+
+    >>> sale.click('manual_invoice')
+    >>> sale.state
+    'processing'
+    >>> sale.invoice_state
+    'pending'
+
+Change quantity on invoice and create a new invoice::
+
+    >>> invoice, = sale.invoices
+    >>> line, = invoice.lines
+    >>> line.quantity = 5
+    >>> invoice.save()
+
+    >>> len(sale.invoices)
+    1
+    >>> sale.click('manual_invoice')
+    >>> len(sale.invoices)
+    2
