Plan the trip, then prove it
Every market visit starts here and ends here. Before you go, lay out why this market needs you in person, who you're seeing and when, and what should look different when you leave. After you're back, open the trip-report link from your approval email, fill in the recap with real expenses and receipts, and the finished report goes to your manager as a PDF. Takes about ten minutes each way. Submit the plan at least a week before you need to book.
