Here is an interesting thought exercise – multiply your annual sales by 1%. Now, add that result to your net income and calculate the percentage of change.
For example: $1 million in sales that is currently producing a net profit of $20,000 or 2% of sales. 1% is an additional $10,000 in profit. That represents a 50% change in net profits.
Pretty significant in anybody's book. Paying attention to your pricing process is very likely to produce a better outcome than guarding against the overuse of office supplies.
