How to Choose a White Label VoIP Provider for Your Business 

After the decision to sell hosted telephony under their own brand name, the next big challenge is who they should work with. There are some telecom wholesalers around that have stood the test of time and there are some new cloud-first platforms, and the distinction is more significant than comparison pages may indicate.

This article outlines some of the pragmatic factors to consider before entering into a reseller agreement with a white label VoIP provider, for IT companies, telecom consultants, and managed service providers new to the white label VoIP market.

Starting with the branding depth, Not the logo

While all providers will say they provide “full white labelling”, it isn’t always the case. See the actual customer facing portal and mobile softphone application before you sign anything.

True white label VoIP reseller programs will use your company name and domain name on the login screen, and on the invoices, mobile apps, and support e-mails. Weaker versions will just rename the invoice, but the app store listing or admin panel will still appear as the name of the original provider. When it’s easy to find the genuine sender, your brand becomes questionable.

Client portal (portal.yourcompany.co.uk) also make sure it is possible to have a custom domain.

Understand the Pricing Structure Properly

Typically, Wholesale VoIP prices are structured into several parts: per number rental, per minute call rates (with international and UK landline/mobile rates being separated), and fee for any added features such as call recording or advanced call management.

Don’t just settle for a headline rate.Don’t take the first rate card you see. Some providers also offer very low rates per minute, but impose an extra fee for number porting, call queues, or IVR menus…all of which soon eat into margin if you feel like you need to include these as standard features.

Also, consider the pricing aspect when your customer base increases. If you’re looking for price-sensitive UK SMEs, you’ll need to offer your customers competitive pricing as you grow because a provider with higher rates at higher volumes will give you that room.

Verify Number Coverage and Porting Process in Check UK

Having the flexibility to provide 03 non-geographic numbers, geographic numbers in the UK and reliable porting from other carriers is a key component to acquiring business customers, who are often reluctant to give up a number they have been using for years.

Inquire directly with the provider for the time needed for porting, what paperwork is required and what occurs if a port fails partway. This is one of the most frequent reasons for customer upset when joining, and as the reseller, it will be your business that will be on the receiving end of the complaint despite the problem being with the underlying network.

Evaluate Admin and Provisioning Tools

The amount of manual work in your team depends on the self-service portal you are provided as a reseller. Check for the following skills:

• Set up new customer accounts and extensions without calling the provider.
• Schedules numbers and controls them directly
• Configure Call Routing, Hunt Groups & IVR Menus for each Customer
• Create usage and billing reports by client.

If the portal is cumbersome or only partially functional, more tickets are sent to the provider, which slows down the process of signing new clients and makes it difficult to expand the business.

When choosing support models, make sure to do so carefully

Typically, there are two types of support available. One of them assigns you the first line of support, and technical escalation is handled by their engineers. In another, the provider provides complete white label support, and accepts calls from customers using your brand name.

Both the models are not wrong but some are suitable for businesses. An IT support company with existing help desk personnel may want to maintain a first line of help desk support, as they’re already close to the client relationship. A single telecom consultant may require the provider to provide complete support, in order to concentrate on sales.

Check the provider’s own customer service responsiveness prior to signing. Ask a question in the selling process and see how many minutes it takes to get a helpful response; this should give you a good indication of what your customer will get.

The Terms of a Contract that One Should Read Carefully

The length of minimum term, volume requirements, and exit terms are different among providers. Others have minimum seating requirements or the reseller has to commit to spending a minimum amount of money per month, which may be limiting if the reseller has not yet saturated their customer base.

Look at what becomes of leaving the program; are customer numbers ported out easily or not? Is it a deliberate policy of the provider? If the provider can assure them that it can provide a viable service, there should be no need to bind resellers with exit friction.

Integration and Feature Set

Phone systems increasingly need to operate with other tools Microsoft Teams, CRM, helpdesk, and more. A provider who already has API documentation and pre-built API integrations provides you with more to offer without the hard work of custom development.

Call recording, voicemail-to-email, mobile apps, and rudimentary call analytics are now standard, not a luxury, for UK companies. These are a part of the default reseller packages offered by providers like Wavetel Business, and they’re an informative indicator of the differences in inclusion versus additional charges from other providers.

Final Thoughts

The decision to go with a white label VoIP wholesaler is made by trying what they actually offer, instead of believing the marketing. Before you sign up, check out their branding depth, pricing transparency, UK number handling and support responsiveness. Any provider that operates effectively on those aspects of the sales process is much more likely to be able to provide your business with a reliable service once you have real customers relying on it.

FAQ

How can I be sure about the quality of a provider’s white labelling? 

Request to try the actual portal and mobile application prior to signing. There’s one thing to know about a provider’s name being mentioned anywhere in the customer-facing experience and it’s that it makes it not fully white label.

Is it better to opt for a low wholesale price provider?

Not necessarily. Take into account call quality, uptime and support responsiveness the problem is that a cheap platform with reliability issues will come with a higher cost of the loss in customers than the savings in margin.

Do the majority of UK providers offer porting from any provider? 

Most providers of the service are able to provide both geographic and non-geographic UK numbers, however, the timeframes for the porting and the success rate will differ, so please be sure to ask questions and not assume.

Which support are you needing when you become a new reseller? 

If you don’t have helpdesk capacity yet, consider a full white label helpdesk solution as your customer’s issues will be addressed properly using your brand name.

If I am not satisfied with the service can I change to another provider later? 

Yes in theory, but certain exit clauses and terms of number portability need to be carefully scrutinised before signing, as switching on an active customer basis is more difficult than switching as a new reseller.
