My two cents on . . . phone numbers
Are you going to use your existing personal cell number as your business line? Don’t forget to change your voicemail message to something appropriate and professional. If not, get started on obtaining a new number. And in the same way that most phones can now juggle multiple email accounts, your phone might be able to receive calls and texts from two phone numbers, allowing you to keep your existing phone and just “add a line” to it.
Another reason to consider a dedicated work number is your area code. If your business story relies on being a local institution, you want a phone number that reflects that. In this day and age, many of us have cell phone area codes from a previous time and location in our lives. (I live in Scottsdale but have a Philadelphia area code even though I haven't lived there for years.) If this is the case with you, you might want to get a new and local number for your business.
There's an additional, almost subconscious reason for women entrepreneurs to have a separate phone line for their business - so that the outside world will take you more seriously. You may be a wife and mother with a side hustle, but potential customers will want to believe you are 100% dedicated to them and their needs. Like a dedicated email address, a dedicated phone number makes it easy for both them and you to know when you are "at work" and when you are not. Think about it - are you just saying, "Hello" when you answer, like you do with your regular phone line, or are you saying, "Hello, this is Jennifer Walker" or "Hello, this is Jennifer at Take the Next Step. What can I do for you today?" Your BFF will laugh if you answer like you're a business but your potential client will think they've dialed the wrong number if all they get is a "hello."
