Key Account Manager Job Description

These are the customers whose departure would show up in a board meeting, which changes the job from relationship management to something closer to insurance. The work is slower, deeper, and judged over years rather than quarters, and the people who are good at it are rarely the same people who are good at chasing new logos.

The draft below assumes a small portfolio held closely rather than a large book worked at surface level. Before you edit, put four facts on the page: the number of accounts, roughly what each is worth, whether a revenue number is attached, and how many nights a month this role spends away. Those four answers describe the job more accurately than any list of duties.

Say what internal access comes with it. Escalations and cross-functional coordination are half of this work, and a key account manager without a route to senior people internally spends their year apologizing to customers. The generator below can produce a retention-focused or an expansion-focused version of the description.

About the Key Account Manager role

A Key Account Manager owns the relationship with a company's most valuable customers, the accounts whose loss would materially hurt revenue. Rather than chasing new logos, they protect and grow existing ones: building relationships across the customer's organization, understanding their business goals, driving renewals and expansion, and coordinating internal teams to keep delivery on track.

The role differs from a standard account manager mainly in depth and stakes. A Key Account Manager typically handles a small portfolio, often five to twenty accounts, builds multi-year account plans, and negotiates complex contracts with procurement and senior stakeholders. In some companies the role carries an expansion quota; in others it is measured mostly on retention and account health.

In your posting, state the portfolio size, the typical account value, whether the role carries a revenue target, and how much travel it involves. Strong key account candidates want to know they will have executive access internally, because escalations and cross-functional coordination are half the job.

Job brief

We are hiring a Key Account Manager to look after the customers we cannot afford to lose. You will build relationships across their organization rather than through one contact, learn their business well enough to be useful in it, drive renewals and expansion, and pull our own teams into line when delivery slips.

This suits somebody patient enough to play a long game and commercial enough to know when to ask. Success here is measured in accounts that renew, grow, and take your call when something has gone wrong.

Responsibilities

  • Own a portfolio of key accounts as their primary point of contact and internal advocate
  • Build and maintain account plans covering customer goals, stakeholders, risks, and growth opportunities
  • Develop trusted relationships with decision makers and expand your contact map beyond a single champion
  • Lead renewal negotiations and secure long-term agreements with favorable terms
  • Identify and close expansion opportunities, including upsells, cross-sells, and new business units
  • Monitor account health signals such as usage, satisfaction, and support history, and act on early warnings
  • Coordinate delivery, support, and product teams to resolve customer issues quickly
  • Run regular business reviews that demonstrate measurable value delivered
  • Forecast renewal and expansion revenue accurately and keep the CRM current
  • Gather and channel customer feedback into product and service improvements

Requirements and skills

  • Has owned major client relationships, as a key account or senior account manager
  • Has retained and grown large accounts, with numbers they can talk through
  • Negotiates real contracts, procurement and legal teams included
  • Builds relationships at every level, from daily users up to the executive floor
  • Runs several complex accounts and internal workstreams at the same time
  • Understands the customer's business model, not only our own product
  • Keeps a CRM and a forecast that other people can rely on
  • A business degree, or the practical experience that replaced one

Nice to have

  • Experience in your industry, where existing relationships and domain knowledge shorten ramp time
  • Formal account planning or strategic selling training
  • Experience working with international accounts across time zones and cultures
  • Background in a delivery or customer success role that deepens empathy for post-sale work
