Yes! ExpenseBot uses columns A through AB for your expense data. You're free to add your own columns (e.g., "Reimbursable," "Department," "Project Code") after column AB — we'll never touch them.
⚠️ Important: Don't insert columns between ExpenseBot's columns (A–AB). This shifts our data out of position and can cause new receipts to land in the wrong columns. If this happens, our system will automatically detect it and move your columns to the end of the sheet to restore the correct layout.
📋 For even more flexibility: Create a Report under the My Reports tab. Reports pull from your master expense data and let you add any columns, filters, or formatting you want — without affecting the main sheet at all.
