Record reasons for your travel
Depending on how your research project is funded, you might have to prove your travel costs are eligible to be reimbursed by the relevant funding body. It is best practice to keep a record of the reason for the trip and relate this directly and clearly to the expected activities of your project description. You should also make sure that the department has approved your travel at a suitable level.
Keep all documents
Funding bodies like the European Commission require clear evidence of the costs incurred, including boarding passes and hard copy hotel check-out documents (ticket purchase confirmations are not sufficient). You should also keep evidence of conference attendance and poster sessions.
