About this example

This example is the monthly invoice a managed IT support company in Sheffield sends an architecture practice: support for 38 users, cloud backup for 41 devices and security monitoring, plus the extra work done in November, including an email migration and a Saturday evening call-out, priced in pounds with 20% VAT.

A service invoice has to show what was delivered as well as what it costs, so this one separates the recurring services from the extra work. Monthly services are billed per user, per device and per site. Additional work is billed by the hour, each line tied to a ticket, an approved quote or the time of the call-out. A work log lists the billable hours by date and ticket, and notes how many helpdesk tickets the monthly fee covered. A service level page compares response time and uptime with the contract targets. The invoice ends with UK bank details, the payment term and the statutory late payment terms.

Who it is for

IT companies, consultants, agencies and other service businesses that bill clients each month for recurring services and extra hours.
