Is there a way to create a report that is similar to the built-in Activity report, but that only shows Slips that meet a specified criteria? I want to be able to do a text search on the Slips and generate a report from those search results.

Though it is possible to create custom reports, what you are asking for is very advanced. You would need to have a good understanding of programming to pull off something like that.

You may want to get in contact with our sales department or a Marketcircle partner and use their services to create a custom report for you.

You can of course use the search feature in Billings 3 to find slips containing specific text, but there is no way to run a report based these results.
