Running a SaaS startup? Then you already know: it’s a bit like building a rocket mid-flight. Your team is remote, your users are global, and your to-do list never ends. Amid all the product tweaks and support emails, one thing matters more than you think — how easily and professionally people can reach you.
That’s where virtual phone numbers come in. Simple to set up, budget-friendly, and surprisingly powerful — they’ve become a go-to communication tool for SaaS startups that want to grow without getting bogged down by clunky systems.
This guide is for founders, ops leads, support managers, and anyone in a fast-moving team who wants to keep things lean and connected.
What Are Virtual Phone Numbers?
In short, it is a phone number that can be used without a SIM card or a mobile phone. All calls are made via the Internet. Your team can receive calls via a browser, IP phone, app, or VoIP software – no matter where they work, at home or in the office.
Here’s what you can get:
Local numbers — to show presence in a certain city or country without being physically there.
Toll-free numbers — for free calls from your customers
International numbers — for regions where you want to build trust with the customer
Calls made to these numbers are routed to your team via the Internet – to laptops, mobile apps, or softphones. No office is required for this, you can work from any convenient place.
Why SaaS Startups Love Virtual Numbers
Let’s look at the reasons why more and more startups are ditching traditional phone systems and switching to virtual numbers.You Can Be Everywhere Without Actually Being There
Imagine: your development team is in Germany, your marketing manager is in London, and your new client is calling from Boston. You don’t need an office in each of those cities, just a local number that rings wherever your team is.Virtual numbers let you:
Offer local support across countries
Launch in new markets fast (test first, scale later)
Avoid expensive international rates
It’s like teleporting your support desk around the world.
Look Bigger Than You Are
A virtual number instantly adds credibility. Even if you have a small team, you will sound like a serious corporation.With one number, you can: Make cheap outgoing calls to almost anywhere in the world
Set up a professional IVR menu (“Press 1 for support…”)
Forward calls based on who’s available
Avoid giving out personal numbers to customers
Your users won’t know you’re still working from a co-working space.
Built for Remote and Hybrid Teams
Modern SaaS teams aren’t sitting together in one building. Virtual numbers are perfect for scattered teams.
You can:
Route calls to the right person based on time zone
Let team members take calls from their phones or laptops
Skip the whole “buying office phones” thing entirely
Whether your support agent is in Lisbon or Milan, calls still get answered.
No Hardware, No Hassle
Traditional phone setups are old technology and it is very difficult to scale to new markets. With virtual numbers, it is much easier: You can add a new number for a new market in a few clicks
You don’t need a technician or cables
You only pay for what you use
If you are scaling quickly, you do not have time for outdated technology, numbers will help you do it easilyBetter Support = Happier Customers
In SaaS, support can make or break your user retention. Virtual phone systems give you tools to:
Handle after-hours calls smartly (voicemail, forwarding)
Assign calls based on priority or language
Plug into Zendesk, Intercom, or whatever helpdesk you use
Even if your team’s small, your support can feel big.
Know What’s Actually Happening on the Phone
You track clicks, signups, and churn — why not calls? With the right setup, you can:
See how long it takes to respond
Track conversion from calls
Log everything to your CRM
You’ll gain a better understanding of how real conversations impact your company’s growth.

Where They Shine:
Sales demos and discovery calls
Onboarding check-ins
Escalations from live chat to voice
Retention and renewal conversations
They’re a flexible way to keep human conversations flowing at all stages.
