Read my review of Xero Projects on Accountex Report
Xero Projects is a simple way for users to track time and expenses on projects or jobs within Xero. It’s designed for small businesses in service industries.
In essence, you can accumulate time entries and expenses on a project, then create an invoice to bill those items to your customer (or not).
You can also budget your time and see if you’re over or under compared to your total project budget.
