On completion of the work both parties (demander and supplier) would sign an LMR worksheet to show that the work had been completed satisfactorily at the agreed rate.
The worksheet is sent to the LMR office where it will be processed to generate an invoice for the demander and a self-billing invoice for the supplier. Invoicing is on a fortnightly basis. The payment from the demander is collected by direct debit on the third week after invoicing. The payment is made to the supplier on the fourth week after the invoice date.
