How to become a white-label VoIP reseller
If you already look after a few businesses’ computers and networks, you’re most of the way to selling them phone service too. This guide covers what a white-label reseller does, what it costs, what you can earn, and the steps to your first customer.
What a white-label VoIP reseller does
A white-label reseller sells business phone service under its own name. The customer signs with you, calls you for help and pays your invoice at your price. Behind the scenes a platform runs the phone system: the switch, the carrier connections, the phone numbers and 911 routing.
It’s one of three common ways to get into phone service, and they’re easy to mix up:
| Model | Who owns the customer | How you earn |
|---|---|---|
| Agent / referral | The carrier | A commission, on their terms |
| White-label reseller | You | The difference between your price and the wholesale rate |
| Wholesale carrier | You | Margin on minutes, after building and running your own platform |
White-label sits in the middle: you keep the customer and set the price, without running servers or negotiating with carriers.
What you need before you start
- Customers who trust you. An MSP or IT shop with a handful of small offices is the ideal starting point.
- Someone who can install a desk phone. If you can plug in a network switch, you can do this.
- A platform. Look for real multi-tenancy, your own branding, published rates and no platform fee. See what multi-tenant should mean.
- A price. Most resellers charge per seat (per user or desk) per month.
The numbers: a 10-seat office
Here is one real example on SimuWave’s published rates: $4 a seat, $1.50 a phone number and 1.9¢ a minute, with no platform fee. The office has 10 seats, 3 phone numbers and each person talks about 250 minutes a month. You charge $30 a seat.
Try your own numbers in the margin calculator. Your real costs also include your time and the phones themselves, which most resellers sell or rent to the customer.
The steps to your first customer
- 1
Sign up and set up your brand
Pick your portal address, add your logo, colors and support email. Your customers will only ever see your name.
- 2
Build your own office first
Buy a number, set up a few extensions and a call flow, and use it yourself for a week. It’s the best demo you’ll have.
- 3
Set your price
Per seat per month is simplest. Decide what’s included (phones, support, minutes) before the first quote.
- 4
Quote the first customer
Count seats, numbers to keep and locations. Every location needs a 911 address.
- 5
Move them over
Port their existing numbers (usually one to two weeks; the old service keeps working until the switch), plug in the phones and build their call flow.
- 6
Bill them monthly
You invoice the customer your price. The platform bills you the published rates.
Mistakes to avoid
- One 911 address for a company with two offices. Set 911 per location, or per desk. SimuWave sets it per extension and lets you test with 933.
- Running a separate server per customer. It works for two customers and hurts at ten. Use a multi-tenant platform from the start.
- Pricing below your time. The platform is the cheap part. Your installs and support are what customers pay for.
- Cancelling the old service too early. Wait until the port completes, or the customer loses their number.
Questions
What is a white-label VoIP reseller?
A business that sells phone service to its own customers under its own brand and its own prices, while a platform provider runs the phone system, carriers, numbers and 911 routing behind the scenes.
How much can a VoIP reseller make?
It depends on what you charge. On SimuWave’s published rates, a 10-seat office billed $30 a seat leaves about two thirds of the bill as margin, every month. The worked example on this page shows the math.
Do I need to become a phone company?
No. The platform carries the carrier relationships, phone numbers and 911 routing. Ask your accountant how telecom taxes and fees apply to what you bill in your state.
How long does it take to start?
You can sign up and have a working phone system on your own account the same day. Moving a customer’s existing numbers (porting) usually takes one to two weeks, and their old service keeps working until the switch.
What phones work?
Grandstream phones set themselves up zero-touch: plug one in and it pulls the right configuration. Most standard SIP desk phones work too.
