The growth and success of your business depends on a good business development and marketing plan. You have some decisions to make, particularly when it comes to staffing and budget. These things need to be planned first, so you can then drive your strategy.
Consider whether you want to hire a dedicated business development person. A talented professional can bring new leads and opportunities into your business. The marketing duties can also fall to a number of different people or be concentrated within one role. It depends on the size of your company, your goals, and how seriously you want to take this aspect of your business.
Once you decide on staffing and resources, you can strategically plan how you want your company to grow. Maybe you want more clients or just more money. Whatever your goals, marketing and business development plans will need to be established first.
