Is working in the extraction of sales and purchase invoices for receivers and satellites permissible or forbidden?

The basic principle regarding working in the preparation of invoices for a company that sells household utensils, including satellites and receivers, is permissibility. However, it is not permissible to work in preparing invoices if the sale of satellites and receivers is forbidden, because that would be considered cooperation in sin and aggression, in accordance with the words of Allah Almighty: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
