In MYOB Accounting Plus terms, the word activity is used to describe a task or service provided by your company for which you can track costs and bill customers on time billing invoices. An example of an activity might be VAT consulting or traveling to a client's office. You also can create activities for tasks your company tracks time for, but doesn't include on time billing invoices, such as employee lunch breaks.
You'll use activities to create activity slips. Activity slips are the records of the activities performed by your company and are the basic recordkeeping unit of the Time Billing Command Centre. Then, you can bill your customers for that time on time billing invoices.
