SALES PARTNER SCOPE

The Real Question: What Do You Want Your Sales Partner to Own?

The service lists overlap considerably. The more useful question is where the external team's responsibility starts and ends.

BUYER TAKEAWAY

Don't choose based on the longest service list. Decide which parts of the sales process you need an external team to own, then compare the actual scope proposed by each provider.

MULTICHANNEL EXECUTION

How Does Multichannel Outbound Compare?

Email, phone and LinkedIn are no longer meaningful differentiators by themselves.

Konsyg, Belkins and Callbox all publicly offer multichannel sales development.

What buyers should investigate is how those channels work together.

01
Email Messaging + follow-up
02
Phone Conversation + qualification
03
LinkedIn Account engagement
COORDINATED EXECUTION One Sales Motion
RESPONSE Follow-up & Optimisation
ASK EACH PROVIDER

Six questions that reveal whether multichannel is truly coordinated

The strongest multichannel programme is not necessarily the one using the most channels. It is the one where those channels operate as part of one coordinated sales motion.

GLOBAL EXECUTION

Global Reach Is More Than a Country List

All three providers publicly support international campaigns. But businesses expanding into another market should look beyond the number of countries appearing on a website.

ASK BEFORE ENTERING A NEW MARKET
THE IMPORTANT DISTINCTION

The important distinction for buyers is not simply whether a provider describes itself as global. It is how execution changes when the buyer changes.

NEW YORK ≠ LONDON ≠ BERLIN ≠ SINGAPORE

A campaign should not simply cross a border unchanged.

TECHNOLOGY & VISIBILITY

Technology Should Make Your Pipeline More Visible

Technology is another area where the providers take different approaches.

01 KONSYG

Konsyg Insights

Konsyg Insights gives clients visibility into campaign activity across channels including email, LinkedIn and calls, while Konsyg's sales-development model can integrate campaign reporting into the client's existing sales environment.

Email LinkedIn Calls Reporting
02 BELKINS

Proprietary Toolset

Belkins currently includes proprietary technology within its wider offering, including Folderly, Frostbite and Charge, alongside reporting and custom integrations for Enterprise engagements.

Folderly Frostbite Charge
03 CALLBOX

Smart Engage

Callbox makes its proprietary Smart Engage technology a central component of its model, supporting campaign execution, prospect engagement and reporting.

Execution Engagement Reporting
THE QUESTION BUYERS SHOULD ASK ISN'T

“Which provider uses AI?”

ASK INSTEAD

“What will my sales team actually be able to see?”

01
Activity Understand what outreach is actually happening.
02
Conversations See how prospects are responding across channels.
03
Meetings Track booked meetings and campaign outcomes.
04
Qualification Understand what makes an opportunity sales-ready.
05
Pipeline Progression Connect outbound activity to commercial progression where applicable.

OPERATING MODEL

Where Do Konsyg, Belkins and Callbox Differ?

Konsyg provides individual sales functions including lead generation, appointment setting, cold outreach, account-based prospecting and SDR pipeline development, alongside broader On-Demand Sales Team support.

All three provide B2B lead generation and outsourced sales-development services. Their published offerings differ in areas such as how services are packaged, technology, reporting, broader sales support and campaign structure.

The way those channels are coordinated and packaged differs, so buyers should confirm the channel mix included in their specific proposal.

04 Which company is best for B2B lead generation?

There is no single provider that fits every B2B sales operation. The appropriate choice depends on factors such as target market, sales-cycle complexity, required channels, geographic coverage, internal sales capacity, reporting requirements and how much of the sales process the company wants to outsource.

05 How should I compare B2B lead generation companies?

06 How much do Konsyg, Belkins and Callbox cost?

Pricing and package structures vary by provider and can change over time. Konsyg provides custom pricing based on campaign requirements. Belkins currently publishes starting prices for some services and also provides customised proposals.
