What is Voice of the Customer (VoC)?

Voice of the Customer (VoC) is the practice of systematically capturing what customers think, want, and need — through surveys, feedback, reviews, and support conversations — and feeding it into decisions. It turns scattered customer signals into a structured input for product, support, and strategy.

How VoC is captured

VoC programs pull from many sources: CSAT/NPS surveys and their open-text comments, support tickets, reviews, interviews, and product usage. The aim is to combine what customers say (direct feedback) with what they do (behavior) into a clear picture of needs and friction that teams can actually act on.

Why support is central to VoC

Support conversations are one of the richest, most honest VoC sources — customers tell you exactly what's confusing or broken. Tagging and reviewing support themes surfaces recurring problems worth fixing in the product or docs, closing the loop between what customers experience and what the company does about it.

Run support from one inbox, not a free-for-all

Selvo's shared inbox turns email into real support: assignments, internal notes, saved replies, SLA tracking, and CSAT — without the duplicate replies and dropped threads a plain distribution list creates.

Questions about Voice of the Customer (VoC)

What are the main sources of Voice of the Customer data?

Surveys (CSAT, NPS, CES), open-text feedback, support tickets, reviews, customer interviews, and product usage data. The strongest programs combine several sources.

How does VoC relate to NPS and CSAT?

NPS and CSAT are VoC measurement tools — structured ways to capture sentiment. VoC is the broader practice of gathering and acting on all customer feedback, not just the scores.

Customer Experience (CX)

Customer experience (CX) is the total impression customers form from every interaction with your brand — marketing, product, support, billing, and everything between. It's broader than any single touchpoint: CX is how the whole journey feels, and it's increasingly the main thing companies compete on.

CSAT vs NPS

CSAT (Customer Satisfaction Score) measures how happy a customer was with a specific interaction, asked right after it happens. NPS (Net Promoter Score) measures long-term loyalty to your whole company, asked periodically. CSAT is transactional and tactical; NPS is relational and strategic. Most support teams track both.

Proactive Support

Proactive support is reaching out to help customers before they ask — anticipating problems and addressing them rather than waiting for a ticket. Examples include status-page updates during an outage, in-app tips at a known sticking point, or messaging customers about an issue before they notice it. It prevents tickets instead of just resolving them.
