What it means
Q1-Q4 are the four quarterly periods of a calendar year: Q1 (Jan-Mar), Q2 (Apr-Jun), Q3 (Jul-Sep), Q4 (Oct-Dec). Amazon and sellers use quarterly reports for performance analysis and forecasting. Q4 is typically the strongest sales quarter, while Q1 is often weaker. Effective quarterly planning with separate inventory and marketing budgets for each quarter is essential for business consistency.
