I cannot express enough how important it is to follow up in business. All of your closings depend on you to follow up! Imagine someone emails or calls you inquiring about your services and telling you they are ready to pay top dollar for them, and you never respond back. That's exactly what happens when you don't follow up on ANY inquiry. If someone shows interest, they are interested. Keep them interested. Be sure you have your set prices and sales pitch handy and be ready to answer any question they have regarding your services.
So many times we forget that it is our responsibility to reach out. Sales are not going to fall in your lap, they require work. Put in the work now and you can grow to where you are able to hire someone to follow up later.
