Governance & Commercial Control

• Manage contractual compliance, pricing discussions, and commercial risk within your account base.
• Ensure CRM data, account notes, and forecasts are accurate and up to date.
• Contribute to continuous improvement of account management processes and best practice.

Skills & Experience

Essential

• Proven experience managing and growing strategic or enterprise accounts within a B2B software or technology environment.
• Strong commercial acumen with experience of contract negotiations, renewals, and long-term agreements.
• Ability to build credibility with senior stakeholders and influence at board or executive level.
