Guidance
If you want full control over pricing and customer billing, choose a wholesale programme such as Gamma, ICUK, NTA or VoIPcloud.
If you prefer lower operational overhead and do not want to manage billing, choose a commission-based programme such as BT Business Partner Channel, 8×8 or RingCentral.
If you want to test the market before committing, start with a referral programme such as Gradwell Referral or Vonage.
If white-label branding is important to your business, check that the provider supports full white-label. Providers confirmed to offer this include NTA, VoIPcloud, Gamma, ICUK, Xelion and VIP VoIP.
If you need monthly rolling contracts with no minimum commitment, consider NTA, VIP VoIP, Xelion or ICUK.
If you want to resell BT Business products without becoming a direct BT partner, use The Network Union as your route to the BT Partner Channel.
Common Pitfalls
Assuming all reseller programmes are the same. Wholesale and commission models differ significantly in how you bill customers and manage margins. Clarify the model before signing.
Ignoring billing platform requirements. Some providers do not include a billing system. If you choose a wholesale model without built-in billing, you will need a third-party billing platform, which adds cost and complexity.
Overlooking contract lock-in. Some programmes require 12 to 36 month contracts. If you are new to reselling, a monthly rolling contract reduces risk.
Not checking number porting support. If your customers need to keep their existing phone numbers, confirm the provider supports number porting before committing.
Choosing on price alone. Margin is important but so are platform reliability, support quality and the range of products you can sell. A low wholesale price means little if the platform is unreliable.
Not verifying provider status. Some providers listed in older directories may have changed their programmes or ceased trading. Always check the provider website directly.
Examples
Example 1: Small IT support company starting VoIP reselling. A small IT company with 50 business clients wants to add VoIP to its portfolio. They have no telecoms billing system and limited staff. A commission-based programme like the BT Business Partner Channel via The Network Union would suit them. BT handles billing and support. The IT company earns commission on each sale.
Example 2: Established MSP wanting white-label VoIP. A managed service provider with 200 clients wants to offer VoIP under its own brand. They already run a billing platform. A wholesale programme from NTA (Enreach) or Gamma would work. Both offer white-label options and the MSP can set its own pricing.
Example 3: Freelance consultant testing the market. A freelance telecoms consultant wants to earn revenue from VoIP referrals without managing accounts. The Gradwell Referral tier or Vonage referral programme would allow them to pass leads and earn a fee without operational involvement.
Metrics and Measurement
Revenue per customer per month. Track the average monthly revenue you earn from each customer across your reseller portfolio.
Customer acquisition cost. Measure how much you spend to win each new VoIP customer including marketing, sales time and onboarding.
Customer churn rate. Monitor the percentage of customers who leave each month or year. High churn may indicate platform issues or poor support.
Margin per product line. Track your margin separately for hosted voice, SIP trunks and any add-on services.
Number porting success rate. If you port numbers regularly, measure the percentage that complete without issues.
Support ticket volume. Track how many support requests you receive per customer per month. This indicates platform quality and customer satisfaction.
Decision Criteria
Use the following weighted criteria to evaluate and compare VoIP reseller programmes. Weights total 100.
| Criterion | Weight | Description |
|---|---|---|
| Sales model fit (default) | 25 | Does the programme match your preferred model: wholesale, commission or referral? |
| Margin potential (default) | 20 | What is the realistic margin based on wholesale pricing or commission rates? |
| Contract flexibility (default) | 15 | Are monthly rolling terms available or is a long-term contract required? |
| White-label availability (default) | 15 | Can you brand the service under your own company name? |
| Billing platform included (default) | 10 | Does the provider include a billing system or do you need your own? |
| Product range | 10 | Does the provider offer hosted voice, SIP trunks, UC and add-on services? |
| Number porting support | 5 | Does the provider support number porting for your customers? |
Process
Follow these steps to select and join a UK VoIP reseller programme.
- Define your business model. Decide whether you want wholesale (you bill the customer), commission (provider bills the customer) or referral (you pass leads).
- Determine your branding requirements. If you need white-label, eliminate providers that do not support it.
- Assess your billing capabilities. If you do not have a billing platform, choose a provider that includes one or choose a commission model.
- Shortlist providers using the comparison tables above. Filter by sales model, contract length, white-label and billing inclusion.
- Contact shortlisted providers to request detailed pricing, margin information and contract terms. Most providers require registration before sharing full commercial details.
- Review the contract terms carefully. Check for minimum commitments, notice periods and exclusivity clauses.
- Set up a test account. Where possible, test the platform before committing to a contract.
- Launch with a small number of customers to validate the service quality before scaling.

FAQ
What is a VoIP reseller?
A VoIP reseller is a business that sells voice over IP telephony services provided by another company. The reseller may brand the service under its own name (white-label) or sell it under the provider brand.
What is the difference between wholesale and commission VoIP reselling?
In wholesale, you buy the service at a reduced price and set your own retail price. You handle billing. In commission, the provider bills the customer and pays you a percentage or fixed fee per sale.
Do I need technical expertise to become a VoIP reseller?
It depends on the programme. Commission and referral programmes require little technical knowledge. Wholesale programmes may require you to provision services and provide first-line support.
Can I resell BT Business products?
Yes. The BT Business Partner Channel allows authorised partners to sell BT products. The Network Union provides a route into this programme for businesses that do not have a direct BT agreement.
What is a white-label VoIP service?
A white-label VoIP service is one where the provider branding is removed and replaced with your own. Your customers see your company name on the platform, invoices and communications.
How much can I earn as a VoIP reseller?
Margins vary by provider and model. Wholesale resellers typically set their own margins. Commission-based resellers earn a percentage of the deal value. Exact figures are not usually published and depend on the provider and volume.
Do I need my own billing system?
If you choose a wholesale model, you may need a billing system unless the provider includes one. Commission and referral models do not require your own billing as the provider handles this.
What contract length should I expect?
Contract lengths range from monthly rolling to 36 months. Providers like NTA, VIP VoIP and Xelion offer monthly rolling terms. Others like Gamma and 8×8 typically require 12 to 36 month agreements.
Is number porting supported?
Most providers listed on this page support number porting. This allows your customers to keep their existing phone numbers when switching to your VoIP service.
What is the Gamma Accelerate Partner Programme?
Gamma Accelerate is a tiered channel partner programme. Partners sell Gamma products including the Horizon hosted voice platform and SIP trunks at wholesale rates. Gamma provides training, marketing support and a partner portal.
