Staying reachable as a solo business: every option

Last updated: September 18, 2026

How do you stay reachable when you work alone?

You have six realistic options: keep using your personal cell, get a second business number, set up your voicemail properly, send customers to WhatsApp, turn on an auto-reply, or hire an answering service. Four of those cost little to nothing. Which one fits depends on how often you get called and how much a missed call actually costs you.

Why a missed call costs you a customer, on the spot

You're up to your elbows in something at 10:20, the phone rings, and by 14:15 you also need to be at school pickup. Whoever called and got no answer often just calls the next name in the search results. How to handle that without hiring staff is something we dig into further in our guide on what to do about missed calls.

This page lines up the options side by side, with honest costs. Phone providers write about this topic too, but they naturally want to sell you their own plan. We don't sell telephony, so we can just tell you when free is good enough.

Option 1: keep using your own cell number

Most solo businesses start this way, and for a lot of tradespeople it keeps working fine. Cost: zero. Customers often like getting the owner directly on the line.

You probably already know the downsides. Work calls follow you on vacation, an unknown number never tells you if it's a client or your kid's school, and if you ever sell the business your number is tied to everything. Workable as long as call volume stays low and you can hold your own boundaries.

Option 2: a second business number on your existing phone

You don't need a second handset or SIM card. Providers like Rinkel deliver a business number through an app on your own phone, starting around 9 euros a month. At Beltify, a fixed business number starts at 5.95 euros a month. Prices change, so check before you pick one.

The big upside: your screen tells you if it's work, and you can route business calls to voicemail outside working hours while staying personally reachable the whole time. For a few euros a month, you're mostly buying peace of mind.

Option 3: take your voicemail seriously

Free, and almost nobody does it well. The default voicemail just says you're not there. A good one says when you'll call back and offers an alternative.

For example: "I'm on a job right now. Leave your name and number and I'll call you back today before 5pm. Texting works too, that's often faster." That costs you two minutes of recording, and it turns waiting into knowing where you stand.

Say your business name, so the caller knows they reached the right place
Give a concrete callback window, not a vague "as soon as possible"
Point to a second route, like WhatsApp or email
Then actually call back at the time you said

Option 4: WhatsApp as your main channel

For a lot of customers, calling is already the second choice. The WhatsApp Business app is free to download and has features the regular app lacks: a business profile and automatic greeting and away messages.

You can answer a text between jobs; you can't do that with a phone call. Put "texting works too" on your site, your voicemail, and your Google profile, and a chunk of your callers solve their own problem. One catch: a chat channel that only answers after two days is worse than no chat channel at all.

Option 5: auto-replies and a callback button on your site

An automatic away message in WhatsApp Business costs nothing and closes the silence gap: the customer knows their message landed and roughly when someone will look at it. That feeling is exactly what goes missing with a missed call.

On your website, a simple callback form can do the same job: name, number, and a good time to reach them. You call back when it suits you. How to set up that kind of safety net when your schedule is consistently full is covered in the guide too busy to answer.

Option 6: hiring an answering service

With an answering service, a real receptionist picks up using your business name, takes the message, and forwards it to you. At Antwoordservice-Telefoonservice, for example, the entry plan starts at 9.97 euros a month plus 1.79 euros per call up to 90 seconds. Run the math on roughly 30 calls a month and you land around 64 euros. Rates and bundles vary by provider, so run your own call volume through the numbers before you sign anything.

When this fits: if you're in a trade where a missed call is lost revenue on the spot, think emergency jobs, and your call volume is too high for callbacks alone to handle. When it doesn't: if customers specifically want to speak with you. A middleman who can only note that you'll call back adds little over a good voicemail, but still costs money every single month.

Which option fits your situation?

Our honest advice for most solo businesses: start free. A recorded voicemail with a callback window plus WhatsApp Business with an away message covers most of the problem, starting today, for zero euros.

If call volume grows or you want to separate work from personal life, a second number for a few euros a month is the logical next step. The answering service is the most expensive option and only makes sense once the cheaper routes are demonstrably falling short.

Few calls, tight budget: a properly recorded voicemail plus WhatsApp Business
Work and personal life blending together: a second number through an app
Full days out on-site: a callback form on your site plus fixed callback windows
Emergency trade with high call volume: consider an answering service and run the cost per call

Frequently asked questions

Do I need a separate business number as a solo business owner?

It's not required. As long as you don't get many calls and it doesn't bother you that work comes through on your personal phone, your own cell is enough. A separate number becomes worth it once your evenings get interrupted or you hesitate over every unknown number wondering whether to answer.

What does a second number on my phone roughly cost?

Beltify charges 5.95 euros a month as an entry price for a fixed business number, Rinkel starts around 9 euros. No extra handset or SIM card needed, it all runs through an app on your current phone.

Is WhatsApp Business actually free?

The app itself, yes, you just download it from the App Store or Google Play. Paid tiers exist too, but those are built for larger companies working through the API. For a solo business, the free app is more than enough.

Isn't an answering service impersonal for a small business?

That risk is real. Many customers pick a small business owner because they want to talk to the tradesperson directly, and a receptionist can only take a message. For emergency trades, catching every call sometimes outweighs that; for most others, it usually doesn't.

Can I combine options?

Yes, and that's usually the best route. A second number backed by a well-recorded voicemail, plus WhatsApp for people who'd rather type, catches more together than any option alone. Start with the free pieces and only add paid layers once you notice you're still missing calls.
