Step-by-step explanation:

While preparing the sales budget, a sales manager should consider the following factors.

*1. Past Sales Figures and Trends*

The sales manager should consider the sales figures of last year and general sales trend. The sales trend is identified with the help of three or more year’s sales figures. The trend may be either upward or downward. The proposed sales budget is prepared by considering the current market condition, last year sales figures and identified sales trend. Moreover, seasonal fluctuations of demand for the product and trade cycle are also considered in the sales budget preparation.

*2. Sales-men’s Estimates*

Salesmen have close contact with customers. Hence, they can estimate the sales in the days to come. The sales manager should consult with salesmen in this regard. However, it should be seen that sales-men’s estimates should neither be over optimistic nor too conservative.

*3. Plant Capacity*

The sales budget cannot exceed the plant capacity available. At the same time, the available plant capacity should be properly utilized. If new plant is acquired, the proposed plant capacity can also taken into consideration for preparing sales budget.

*4. Availability of Raw Materials*

Sometimes, the raw materials are in short supply. If so, the sales budget is prepared on the basis of availability of raw material.
