When you’re starting a business on a budget, every expense matters. You want to look professional, but does that mean paying for a separate business phone line? Many solo entrepreneurs assume they need a completely new phone, but that’s not always necessary.
Using your personal cell phone might seem like the easiest solution, but it comes with problems. Mixing business and personal calls can get confusing. You might miss important calls, struggle to keep work and personal voicemails separate, or regret giving customers direct access to your personal number.
If you’re working with a small startup of two or three people, having a dedicated business phone line can make things much easier. Instead of everyone using their own phones, a shared business number lets you manage calls in one place. You can even set up an auto attendant to route calls so one person handles sales while another takes care of support.
The good news is that setting up a business phone line doesn’t have to be expensive. There are affordable ways to get a professional business number without paying for extra hardware or an expensive phone plan.
In this guide, we’ll go over the cheapest options, compare costs, and walk you through how to set up a business phone line without spending more than you need to.
1. Do You Really Need a Separate Business Phone Line?
Many new business owners wonder if they really need a second phone line when they could just use their personal cell phone number. The short answer is that it depends on how you want to present yourself and manage your calls.
Having a dedicated business phone line helps keep things professional. When customers call, they expect to reach a business, not a personal voicemail or someone answering casually. A business number also keeps your personal number private, so you’re not getting business calls late at night or on weekends.
A separate line also makes organization easier. You can set up business hours, route calls to the right person, and use voicemail features that are built for handling customer inquiries. If you have a small team, a shared number allows multiple people to manage incoming calls, making it easier to stay on top of customer service.
When choosing a provider, here are the key features to look for:
- Virtual Number – Choose a local, toll-free, or vanity number to match your business needs and brand.
- Call Routing – Redirect calls to your cell phone or team members so you never miss an opportunity.
- Custom Greeting – Set up a professional voicemail or auto-attendant message for incoming calls.
Next, we’ll walk through the steps to get a cheap business phone number so you can start taking calls right away.
While it’s possible to use your personal number for business, it can quickly become a hassle. A business phone line gives you more control over how you handle calls without breaking the bank.
The key is finding the cheapest option that still works for your needs.

3. How to Set Up a Cheap Business Phone Line in 4 Steps
Now that you know the most affordable options, let’s go through the simple steps to set up your business phone line without overspending.
Step 1: Pick a Provider That Fits Your Budget
There are plenty of low-cost business phone services that give you a dedicated number, call management features, and flexibility. Look for a provider that offers the features you need at a price that makes sense for your business.
Cheapest business phone line providers:
- Unitel Voice – starting at $9.99/month
- eVoice – starting at $14/month
- Grasshopper – starting at $18/month
Step 2: Choose a Local or Toll Free Number
Decide whether you want a local number that makes you look like a neighborhood business or a toll free number that gives your business a national presence. Most providers also offer vanity numbers, which make your number more memorable.
Step 3: Set Up Call Forwarding & Voicemail
Make sure your new business number is set up to forward calls to your cell phone, computer, or other devices so you never miss an important call. Set up a professional voicemail greeting so customers know they’ve reached your business, even if you can’t answer.
Step 4: Use an App to Manage Calls on Your Existing Phone
A business number app is the easiest and cheapest way to handle business calls. Most virtual phone systems offer an app that lets you make and receive calls, send texts, and manage voicemail all from your personal phone, without mixing business and personal calls.
Once you’ve completed these steps, you’ll have a fully functional business phone line at a low cost, giving your business a professional edge without unnecessary expenses.
4. Start Cheap, Then Upgrade as You Grow
Setting up a virtual business phone line doesn’t have to be expensive or complicated — many affordable options let you manage calls from your existing devices without extra hardware.
The key is to start with a simple, low-cost solution that gives you a dedicated number and the basic features you need to manage calls professionally. As your business grows, you can always upgrade—whether that means adding multiple phone lines, setting up an auto attendant, or even using a physical desk phone.
Many affordable business phone options exist, but be wary of free business number offers. Many free services come with limitations like restricted call minutes, ads, or the inability to port your number later. Choosing a provider that lets you keep your number and scale up as needed is important.
Just make sure that you own your business number and have the right to transfer (port) it to another provider if needed. That way, you’re not locked into one service and can switch or expand without losing the number your customers already know.
By starting with an affordable option now, you get the benefits of a professional business line without unnecessary costs. And when the time comes to upgrade, you’ll have the flexibility to scale up in a way that fits your business.
