MESUN is available to administrate your invoice management, and we do so with great care. We follow the process according to our customers’ wishes. Some customers want to email us the basis so that we can create the invoice, print, afterward send the invoices, others want to send-in papers, email us, post, scan-in or send as pictures. Making sure that customers are billed and money comes-in as it should according to the invoice statement is our responsibility when we are hired. Sometimes we do credit control if we are permitted.
