Account Manager; Existing Business

Position: Account Manager (Existing Business)
The role
Cost Perform is looking for an Account Manager (Existing Business) who will take ownership of our enterprise customers after the sales phase and focus on building strong, long-term relationships while driving account growth.

This is not a traditional Customer Success role focused on building processes or frameworks. Instead, this role is centered around relationship ownership, commercial awareness, and customer engagement within a complex, data-driven product environment.

You will work closely with CFO-level stakeholders and finance teams, ensuring they get value from the platform while also identifying opportunities for expansion. An affinity with finance, costing, and data analysis is important — you don’t need to be a specialist, but you should feel comfortable discussing financial performance and insights.

The role suits someone who is commercially sharp, people-oriented, and energized by managing and growing strategic accounts.

Cost Perform is a financially stable SaaS company with a long track record. We are entering a next phase where strengthening customer relationships and unlocking growth within our existing customer base is key — without the chaos or pressure of a startup.

Own a portfolio of enterprise customers after sales handover
