To forecast sales effectively, start by analysing historical sales data, identifying seasonal trends, and considering external factors such as market conditions, consumer behaviour, and economic indicators. Use tools like spreadsheets, CRM systems, or dedicated forecasting software to model different scenarios. Incorporating both quantitative methods (like time-series analysis or regression) and qualitative insights (such as input from your sales team or market research) helps improve accuracy. Regularly updating your sales forecast ensures it remains relevant and responsive to changes, ultimately supporting better business planning and decision-making.
