Track stock ageing automatically by IMEI with MobileStock.

Why Stock Ageing Matters in Phone Resale: Unlike general retail goods, consumer electronics and mobile devices depreciate quickly as next-generation hardware is announced and released. Devices lingering in stock past 60 days frequently erode initial 15-25% gross margins down to breakeven or net losses. MobileStock tracks IMEI intake dates and alerts you before stock ages into unprofitable territory.
