Consolidating activities
If you mark the "Consolidate Activities on Invoice" option, all the activity slips with the same activity ID will be consolidated into a single line item on the customer's invoice. If you've assigned jobs to the activities, activity slips having the same activity ID and job number will be consolidated.
Consolidation can be useful if you've recorded many activity slips that don't merit detailed information. For example, you might consolidate all your photocopying charges into a single line item on the invoice. Be careful, though -- if you mark the consolidation option, all similar activity slips will be consolidated. You cannot select the activities that will be consolidated.
If you're unsure whether to consolidate line items, make whatever entries are needed to the activity slip information, mark the consolidation option, and click Prepare Invoice. Carefully examine the line items that appear in the Sales window. If they meet your needs, you can record the invoice. If you're not happy with the results, click Cancel in the Sales window and return to the Prepare Time Billing Invoice window. Reenter your invoice information without marking the consolidation option.
