I received a single order for supply, erection and commisioning. The finished components against the order, shall be despatched in various lots over 2 month , and then within a month it shall be erected and commisioned.
On what documents I should move the material to the site and how can I raise single invoice for the total order value?
note: since the order from customer (a goverment organisation) is single order, I can not make multiple Invoices to the customer.
