Summary

At every buying stage, roughly one-third of B2B customers prefer in-person, remote, or self-serve — McKinsey's rule of thirds reshapes coverage models.

The Rule of Thirds

McKinsey's B2B Pulse 2024 research, published in 'Five Fundamental Truths: How B2B Winners Keep Growing,' finds that at any stage of the buying journey, about one-third of customers prefer in-person interactions, one-third want remote (video/phone), and one-third prefer digital self-serve. This split holds across geographies, industries, and deal sizes.

The implication for sales leaders is blunt: single-channel strategies under-serve two-thirds of buyers at any given moment. Winners design omnichannel journeys where buyers switch modes without losing context.

E-Commerce and Channel Economics

B2B buyers now use an average of ten interaction channels, up from five in 2016. Among suppliers offering e-commerce, digital is often the top revenue-generating channel — more than one-third of revenue — while in-person's share of wallet has declined. Buyers are comfortable placing orders above $500,000 through remote and self-serve channels when the experience is seamless.

Companies embedding omnichannel effectively show EBIT growth of 13.5% versus 1.8% for digital laggards in McKinsey's comparative analysis — a gap too large to ignore in margin-focused environments.

  • Omnichannel sales teams aligned to account segments
  • Advanced sales technology and analytics
  • Hyper-personalization using first- and third-party data
  • Marketplace and e-commerce excellence

Gen AI and the 1.7× Market Share Effect

McKinsey reports 19% of B2B sales organizations already implementing generative AI successfully, with another 23% experimenting. Teams blending personalized experiences with gen AI are 1.7× more likely to increase market share. This connects to coverage design: AI handles research and content variation; humans handle consensus, politics, and trust.

Practical Actions for Sellers

Map your accounts against preferred channels using CRM and buyer feedback — do not assume enterprise equals field-only. Pair inside sales efficiency with strategic in-person moments (executive workshops, QBRs).

For sellers, McKinsey's findings reinforce MEDDPICC discipline on multi-stakeholder access: digital may open the door, but complex deals still require champions and economic buyer alignment across channels.
