Most enterprises have no problem handing off customer service to an outside partner. Billing disputes, tech support, and returns are all fair game when it comes to outsourcing. Yet, the moment the conversation shifts to revenue-generating functions like sales, leaders become more cautious. Sales is often perceived to be too close to the brand, too strategic, and too important to trust to anyone outside the building.

That logic is costing companies growth.

A recent IDC InfoBrief, “From Efficiency to Excellence: Driving Enterprise Value Through Customer Experience Partnerships,” sponsored by TELUS Digital, draws on survey data from 287 enterprise decision-makers on their business priorities and CX partnership strategies. The results show a striking imbalance in modern outsourcing. 

The Trust Gap Is the Real Bottleneck

Organizations are comfortable delegating customer friction, but they remain tethered to an outdated belief that revenue-generating functions must stay strictly in-house to maintain control. That mindset is holding enterprises back. 

According to IDC’s InfoBrief, customer analytics is now the most outsourced function to CX partners, cited by 27% of respondents. Inbound B2B sales trail at 17%, inbound B2C sales at 9%, and outbound sales functions rank even lower.

The disparity is telling. Enterprises are willing to hand over the data and insight layer of the customer relationship, but they still hesitate at the transactional moment. Modern CX outsourcing has evolved from transactional labor to high-fidelity brand extension. The barrier isn’t a lack of partner capability. It’s a legacy mindset that treats sales as ‘core identity’ and service as a ‘utility.’ When enterprises mistake proximity to the office for quality of the outcome, they inadvertently limit their own scale.

Same Tools, Different Silos

Consider this: the same AI and predictive analytics that enterprises deploy to resolve support tickets are perfectly suited for identifying upsell triggers, forecasting churn, and surfacing expansion opportunities.

The IDC data shows that 34% of enterprises rank improving operational efficiency as their top priority over the next 12 to 24 months, with 31% prioritizing improved customer experience and 21% focused on revenue growth. Most companies chase these with separate budgets and separate teams. But think about what actually happens in a single customer interaction: an AI tool resolves an issue faster, and that’s efficiency. The customer walks away satisfied, and that’s experience. And because the system flagged a cross-sell opportunity during that same conversation, the agent closes an expansion, and that’s revenue. One interaction, one platform, three outcomes. The only reason companies don’t see it that way is that they’ve organized themselves not to.

Technology and talent are commercially agnostic. Only internal silos prevent a service tool from becoming a revenue engine. CX partners, by nature, sit outside organizational walls. The best among them have spent years perfecting the science of hiring, training, and scaling the specific skill sets required for consultative, high-conversion interactions.

When Procurement Undermines Growth Strategy

The most significant insight from the IDC InfoBrief concerns how enterprises buy CX partnerships. Contract pricing and flexibility are the top vendor selection factors at 28%, and 72% of enterprises expect 10% to 19% cost savings from their CX partner. Cost discipline matters, of course. But when pricing is commoditized, partners are forced into a defensive posture, focusing on baseline service level agreements (SLAs) rather than proactive growth.

In a revenue partnership, the conversation must shift from cost per head to return on investment. In a service-only model, success is often measured by how quickly you can get off the phone. In a revenue partnership, success is measured by conversion rates, pipeline contribution, and account expansion. 

Enterprise leaders need to think beyond the cost of a partner, considering how effectively they can accelerate outcomes and shorten the sales cycle. IDC’s data shows that 22% of enterprises already view revenue growth as a quantifiable outcome of their CX partnerships. That number should be much higher. You cannot expect a vendor to drive strategic growth if the contract is designed only to manage tactical costs. A true revenue partnership transforms the CX provider from a defensive cost center into an offensive growth engine that pays for itself.

Agentic AI Changes the Math

The emergence of agentic AI accelerates all of this. According to IDC, 32% of enterprises have already deployed agentic AI use cases in their outsourcing operations, and only 6% report no interest in the technology. This is no longer about chatbots deflecting routine inquiries. Agentic AI analyzes behavior in real time to trigger next-best-action recommendations, ensuring expansion opportunities aren’t missed during a service interaction. It moves CX from manual task execution to autonomous revenue orchestration.

For CX partners already managing both the data layer and the customer interaction, agentic AI can be the connective tissue that turns a support conversation into a qualified pipeline event.

The Full-Lifecycle Imperative

The enterprises that will pull ahead are the ones that stop treating acquisition, retention, and expansion as separate workstreams managed by separate vendors. Deploying a single partner across the full customer lifecycle ensures data continuity, with the sales team informed by support data and the support team staying aligned with the original value proposition. IDC’s data reinforces this: 25% of enterprises say the highest satisfaction driver is alignment of service delivery with their business. A fragmented customer journey is a silent revenue killer. A unified lifecycle is a force multiplier

Time to Rethink the CX Partner Relationship

The CX outsourcing market has matured well beyond transactional staffing models. The partners, the technology, and the talent models exist today to drive measurable revenue impact. What hasn’t caught up is the enterprise mindset. The risk isn’t in outsourcing sales, but in the cost of not scaling it.

For leaders still treating their CX partner as a cost center, the IDC InfoBrief sponsored by TELUS Digital offers a clear direction: the same partnership you’re using to manage friction could be the engine that drives your next phase of growth.
