Data and Analysis
High-quality data is the cornerstone of effective forecasting. It's essential to prioritize data quality to get reliable and accurate forecasting.
You'll need clean, reliable data to use historical forecasting, which takes into account past sales data over a given period of time. Historical forecasting is best for organizations that operate within a steady marketplace.
A historical forecast operates on the assumption that buyer demand will increase and that your ability to close deals will not be affected by external factors. It should be treated as more of a benchmark than your be-all-end-all prediction.
To calculate a historical forecast, you can look at monthly recurring revenue (MRR). For example, if your sales reps sold a total of $100,000 in June, you'd lean on the assumption that they'd make at least $100,000 in July, too.
Adding your historical growth percentage can make your projection more accurate. For instance, if your sales team has consistently increased sales by 5% each month, you can safely estimate that they'll reach $105,000 in sales for July.

The amount of historical data you have will always limit the method you choose. If you've been capturing accurate data over a longer period of time, you can use that data to create a forecast that acts as a benchmark for future demand.
Assessing historical trends by examining sales from the previous year can help you build a sales run rate. This is the amount of projected sales per sales period, which forms the basis of your sales forecast.
Implementation and Planning
To create an effective sales forecasting plan, it's essential to identify the key drivers of sales growth. This involves analyzing historical sales data, customer behavior, and market trends.
A good starting point is to use the moving average method, which involves calculating the average sales over a set period to predict future sales.
Regularly reviewing and updating the sales forecasting plan is crucial to ensure it remains accurate and relevant. This can be done quarterly or annually, depending on the business's needs.
Using the linear regression method, sales teams can identify the relationship between sales and external factors such as seasonality or economic indicators.
The plan should also include a review of sales performance metrics, such as sales velocity and customer acquisition costs.
By incorporating these methods into the sales forecasting plan, businesses can gain a better understanding of their sales trends and make more informed decisions.
