Berkeley Myles Group, builds on-premise ERP/MIS software for SMEmanufacturers — covering MRP, job costing, stock control, works orders and labour tracking, withintegrations into Sage, Xero and Pegasus. We work with 700+ customers across motor sport, aerospace,defence and electronics.

Berkeley Myles Group has recently brought Javelin into the business, bringing together two established manufacturing software providers under one roof. We are part of the Banyan Software portfolio and are investing in a cloud relaunch of the platform, landing in Q4 2026 — a genuine growth phase for the business, not a maintenance one.

This is a new role for Berkeley Myles — created to build a dedicated Account Management function fromthe ground up. As Key Account Manager, you’ll own and grow our entire existing customer base (700+ SME manufacturers) once integrated, focused on retention, licence expansion and module growth.

You’ll work with production, operations, finance and IT stakeholders inside SME manufacturing businesses— helping them get more value from the system they already run, and identifying where additional modules, users or capability can support their growth.

You report directly to the Commercial Director, and will play a central role in shaping how Berkeley Myles does account management going forward. In our own GTM model, this role owns three stages end to end:
Adoption, Expansion, and Advocacy &Referral. Everything before that (Awareness, Nurture, Sales, Close) sits with Marketing and the BDR team— your world starts once a customer is live.

You’ll carry clear commercial targets across retention, renewal and expansion revenue, set by the Commercial Director and reviewed regularly. We’re not looking for someone who manages relationships and waits for renewals to happen; we’re looking for someone who goes after the number. You will:

• motor sport, aerospace, defence, electronics and beyond
• Build trusted relationships with production, operations, finance and IT stakeholders within existing accounts
• Develop and execute account plans focused on retention, licence expansion and module growth
• Lead commercial conversations on renewals, upsell and expansion — owning the numbers behind them
• Consistently meet or exceed the quarterly and annual retention and expansion revenue targets set for
• the role
• Identify growth opportunities within accounts, working with Support, Implementation and Product to drive adoption and uncover expansion potential
• Spot accounts missing key modules — accounts link, quality, shop floor, debt collection, labour, and time; attendance — and build the case for adding them
• Understand our subscription vs. perpetual licensing options well enough to guide customers to the right commercial fit as we transition toward subscription
• Maintain disciplined CRM and forecasting hygiene in Hub Spot, giving clear visibility of account health and pipeline
• Build the structure and processes for account management across a couple of products.
