# Analytics

Analytics shows aftermarket sales and install base data by brand and model code. Use it to see which models sell best, which customers hold the largest installed base, and which spare parts to stock. Sales reps, inside-sales staff, service managers and account owners use these tabs to plan outreach and stocking decisions.
