Set your markup in the control panel's Quoting tab, as a percentage by trip size: one for trips under $15,000 (with a minimum in dollars), one for $15,000 to $50,000, and one for trips over $50,000. ASTRA fills it in on every bid, and you can change it on any option before you send it.
You can also round every client price up to the nearest $10, and add the logo that goes on your client quotes.
