UK VoIP reseller
programmes comparedand how to choose your partner.

Before you can get started reselling, or even choosing a supplier for that matter, you’ll need to evaluate what your business can effectively offer to customers and what the operational and financial responsibilities of each supplier’s commercial structure is. Given that each supplier offers different terms and responsibility-shares, you’ll often find that evaluating what you can offer your customers will narrow down choice of partner programme.

Key Questions Answered

Do you prefer a white-label brand of your own or a commission-based agent role?

Arguably the best way to differentiate between different vendor reseller programmes, by determining and choosing an agent role (such as standard referral or agency tracks) you can minimise financial risk and administrative overhead (as billing, tax collection, and network management remain with the carrier), or alternatively an own-brand wholesale or white-label approach maximises customer equity and control over retail margins, though requires you to absorb credit risk, handle customer complaints, and manage first-line support.

Are you planning to sell hosted cloud PBX software, SIP trunks, or physical office phones?

When reselling VoIP, each of hosted cloud PBX software, SIP trunks and physical office phones represent their own distinct revenue streams. Hosted cloud PBX packages provide multi-site user licences and feature logic (like auto-attendants and mobile apps), SIP trunks deliver concurrent call capacity to existing on-premise PBX hardware and physical phones or ATAs fulfil the physical endpoints required on site. Most comprehensive deployments combine software seats, active call paths and hardware endpoints.

Depending on the reseller model you choose, you’ll get access to different earning potential.

Agent / Commission Model:

Earnings are calculated as an agreed percentage or fixed amount of the qualifying contract value (either upfront or spread across recurring terms). We always recommend that you verify whether commissions trigger upon order sign-off, live service activation, or initial invoice payment to find out when exact payments are made.

Whitelabel / Wholesale Model:

With wholesale and white-label routes, you buy services at an agreed rate and set your own retail prices and branding. The difference is gross margin, not net profit: billing, payment processing, support, fraud, bad debt and customer acquisition all affect the outcome. Entry costs and commitments vary by provider; neither higher net profit nor a large pre-existing customer base should be assumed.

MSP with an existing client base but no internal voice desk

Recommended Route: Provider-billed partner programmes (such as BT via Netify).

We’d recommend this path to smaller resellers or where VoIP is not your primary business offering, allowing you to upsell cloud telephony and secure connectivity alongside your current offerings, and without absorbing Tier-1 network troubleshooting or billing compliance burdens.

Startup building an independent telecommunications brand

Recommended Route: Either provider-billed partner programmes (such as BT via Netify) for selling established provider-branded services, or white-label platforms (such as Yay.com or The VoIP Shop) for building your own telecommunications brand. White-label arrangements can give you retail pricing, branded invoicing and customer-management tools. The exact branding, contractual control, support duties and commitments depend on the agreement; higher net profit is not guaranteed.

Traditional PBX installer maintaining legacy infrastructure

Recommended Route: SIP trunking and software platform distributors (such as 3CX or Voiceflex integration routes).

Enables you to migrate legacy customer PBX hardware to modern IP networks whilst still retaining familiar on-premise installations.

We’d recommend the Netify Reseller Programme for IT companies, MSPs, telecom providers, connectivity partners and telemarketing agencies who are looking to add hosted VoIP to a reseller portfolio. As a BT Authorised Partner since 2012, we recruit Authorised Resellers of BT across the likes of BT Cloud Voice Express, BT Cloud Voice and BT Teams Voice. In this, BT designs, delivers and operates the service and you act as a dealer earning commission.

BT Cloud Voice

BT Cloud Voice is BT’s cloud hosted business phone system, priced per user per month across three feature packs with a call plan charged separately.

BT Cloud Voice Express

Cloud Voice Express is a separate product rather than a cut-down tier of Cloud Voice. It is a digital phone service for smaller businesses, available with eligible BT Business broadband packages. BT currently describes support for up to four phone numbers across four business locations; confirm the exact line, site and package configuration before quoting. Existing numbers may be retained through an eligible transfer, subject to availability and porting checks. Self-install equipment, the CVE app and call plans depend on the package. Where a site needs more complex call handling or Webex features, assess full Cloud Voice against the actual requirements.

BT Teams Voice

BT Teams Voice adds PSTN calling to Microsoft Teams. Check the customer’s eligible Microsoft 365 and Teams licences, Teams Phone entitlement and BT calling service together. Existing subscriptions, bundled entitlements and the chosen deployment determine which additional licences are required; there is no universal three-subscription rule. Resellers can position Teams Phone and BT Teams Voice for customers already using Microsoft 365, after checking their current licences and calling requirements.

BTnet with Cloud Voice (as a cross-sell opportunity)

The natural attach for voice deals is connectivity, and the two can be considered together. Assess the customer’s broadband or BTnet leased-line capacity, resilience and voice requirements as one conversation. Confirm the supported access service, billing arrangement, current connection charges and any promotional waiver in the written quote. Eligible connectivity and voice sales can each earn commission under their applicable programme terms.

Why Netify?

BT Wholesale publishes a route for businesses to become wholesale customers, with product-specific trading, credit and commitment requirements to confirm. The public material reviewed does not establish a universal £1m annual minimum. The Netify BT Reseller Programme provides an alternative dealer route for eligible BT Hosted VoIP, BT SD-WAN, BT SASE, BT Business Broadband and BTnet Leased Lines, with no minimum spend and no sales targets under the Netify programme. For BT Cloud Voice, commission is based on total contract value, with 50% paid upfront and 50% on completion. Rates, qualifying orders and payment conditions are confirmed in writing; other products may have different schedules.

When getting into reselling VoIP, we’d recommend considering the following metrics and how they may affect your offerings or outcomes for customers:

• Revenue per customer per month - the average monthly revenue you earn from each customer across your reseller portfolio.
• Customer acquisition cost - how much you spend to win each new VoIP customer including marketing, sales time and onboarding.
• Customer churn rate - the percentage of customers who leave each month or year. High churn may indicate platform issues or poor support.
• Margin per product line - 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 - how many support requests you receive per customer per month. This indicates platform quality and customer satisfaction.

When deciding which VoIP reseller programme to go with, we’d first recommend considering all of the aforementioned steps to eliminate anything that doesn’t fit your business, then we’d suggest using the below table (or similar) to evaluate and compare different criterion of each VoIP reseller programmes.

Regardless of which reseller programme you opt for, we recommend checking the following potential pitfalls before committing.

• 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.

Programme Selection & Vetting: Submit business credentials and company registration documents. Credit checks should be completed where required by the selected programme.

Training & Demo Access:  Where required by the selected programme, complete product accreditation, configure Not-For-Resale (NFR) demo accounts, and familiarise your team with administrative provisioning tools.

Customer Qualification: Audit the client's current estate using technology checkers (verifying broadband speed, existing line types, and legacy dependencies like alarm lines or card machines).

Quotation & Order Execution: Generate compliant quotes matching the customer's call volume, handset requirements, and feature pack preferences, ensuring Number Portability Authorisation Forms (LOM/LOA) are secured.

Migration & Support Handover: Coordinate porting lead times, dispatch pre-configured hardware, and execute the service cutover according to the agreed support boundary model.

Follow these steps to select and join a UK VoIP reseller programme.

1. Define your business model. Decide whether you want wholesale (you bill the customer), commission (provider bills the customer) or referral (you pass leads).
2. Determine your branding requirements. If you need white-label, eliminate providers that do not support it.
3. Assess your billing capabilities. If you do not have a billing platform, choose a provider that includes one or choose a commission model.
4. Shortlist providers using the comparison tables above. Filter by sales model, contract length, white-label and billing inclusion.
5. Contact shortlisted providers to request detailed pricing, margin information and contract terms. Most providers require registration before sharing full commercial details.
6. Review the contract terms carefully. Check for minimum commitments, notice periods and exclusivity clauses.
7. Set up a test account. Where possible, test the platform before committing to a contract.
8. Launch with a small number of customers to validate the service quality before scaling.

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.

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.

What contract length should I expect?

Contract lengths and commitments depend on the product and agreement. NTA and VIP VoIP publish flexible or monthly rolling propositions. Confirm current terms for Xelion and every other shortlisted provider rather than assuming one term covers its entire portfolio. Distinguish the partner agreement, platform subscription, end-customer service term and software licence renewal.

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.

How do I handle billing and collections?

If operating via an agency or referral model, the primary carrier manages all invoicing and payment collection. Under white-label wholesale arrangements, resellers need a billing and collection arrangement, which may be supplied directly by the wholesale platform (such as built-in engines from platforms like The VoIP Shop), integrated via third-party software (such as Stripe, GoCardless, or through more-specialised telecom billing software), or operated independently.

What compliance and emergency service checks are needed?

Emergency-calling responsibilities and resilience mechanisms must be clearly established within the service delivery model.

Under Ofcom General Condition A3, communications providers must take all necessary measures to maintain uninterrupted access to emergency organisations. Ofcom’s power-cut guidance sets expectations for suitable resilience solutions, including at least one solution enabling emergency access for a minimum of one hour and free provision for customers at risk because they depend on their landline. Assess customer needs, emergency addresses, vulnerable users and the complete power-dependent call path. One hour is not a universal business-continuity guarantee. Resellers and underlying providers must establish their respective operational responsibilities; their agreement does not by itself transfer statutory obligations.

Can I supply mobile apps and remote working tools?

Eligible cloud voice packages, including BT Cloud Voice Express and supported Webex plans, provide mobile or desktop apps for making and receiving business calls. Features and supported devices vary by product and licence. Teams Phone Mobile is a separate operator-integrated service using a SIM-enabled mobile number with Teams; it is not interchangeable with a standard VoIP softphone.

Can Netify help me become a Hosted VoIP Reseller?

Yes. Netify is an Authorised Partner of BT. Subject to programme approval and product eligibility, resellers can offer BT Cloud Voice Express, BT Cloud Voice and BT Teams Voice through the Netify route. Available devices and integrations depend on the selected BT product. This does not independently confer a direct partnership or accreditation with Cisco, Yealink, Poly, Jabra or Microsoft.

How do I become a BT Hosted VoIP reseller?

Apply to the Netify BT Reseller Programme. Once approved and onboarded, the dealer model lets you sell the eligible BT Cloud Voice Express, BT Cloud Voice and BT Teams Voice products confirmed for your agreement without operating your own hosted-voice platform. BT designs, delivers, bills and supports the service. Eligible sales, upgrades and re-signs earn commission. BT Cloud Voice commission is calculated on total contract value, with 50% paid upfront and 50% on completion; other products may have different schedules.
