Lightning.app 與 21energy 使用情況與統計

LIghting helps manage your customers in the same way that your phone book works on your phone. It also allows you to mark each record with colours so that you know which customers owe you money, which customers you need to send a quote to, and it also lets you save photos and notes directly in a customer record so you can keep all your photos and notes for customer work in a customer record.
