IntegrityError comes from the database, so django was happy with having payed_at=None, but your database wasn't. I suspect you added null=True to your model after having run syncdb, and the database table does not reflect the model. Remember that syncdb does not modify tables that already exist, or validate that they match their corresponding models.
