Pain: manager spent 10-15 min per calculation — searched ATI rates, calculated distance, applied coefficients. No rates for small towns — had to guess. Solution: calculator pulls live ATI rates, calculates distance via Yandex, for villages uses SmartPrice (median from 3-5 nearest hubs + remoteness surcharge). Accuracy improved from 20% to 80% for small settlements.
