As an accredited training firm, we’re committed to providing first‑class professional development in a supportive and friendly environment. Through our Level 4 Accountancy Apprenticeship, you will gain hands‑on experience, develop essential skills, and build the foundation for a successful career within accounts and business advisory. You will work with businesses across a wide range of sectors, delivering exceptional client service while earning a Level 4 Diploma in Professional Accounting from the Association of Accounting Technicians (AAT).

The Moore Mentum team delivers growth advisory services to SMEs, through structured programmes that guide clients on a journey from defining their vision to identifying innovative ways to stand out. Acting as trusted advisors, the team helps clients maximise what they have by improving their efficiency, productivity and increasing their business value for eventual sale.

From the outset, you will work closely with a portfolio of clients with whom we build long‑term, trusted relationships. You’ll meet with them regularly – at least on a monthly basis – and become a consistent point of contact as you support them through ongoing projects. You’ll get to know their businesses, uncover the obstacles they face, and become familiar with their sectors.

Rather than purely short‑term assignments, much of the work is continuous and evolving, giving you the opportunity to see the impact of your advice over the longer term. We encourage you to take responsibility early on, allowing you to gain exposure to all aspects of the role.

With support and training, key responsibilities in the first 12 months will include:

• Supporting the team with the preparation of monthly management accounts for owner managed businesses, including posting journals and reviewing results
• Assisting with bookkeeping queries using cloud accounting software such as Xero and Quick Books
• Supporting process improvement work, including system set ups, reviews and streamlining finance processes
• Helping clients improve their use of finance systems to gain better real‑time insight into their business
• Assisting with the preparation of client dashboards, KPIs and performance metrics
• Using Excel extensively to analyse data to provide insight to our clients used to support business decisions, not just compliance
• Helping to prepare cash flow forecasts, budgets and simple financial models
• Learning how to interpret financial information and identify trends, risks and opportunities for clients
• Learning how different business models work and how financial performance links to operational activity
• Developing an understanding of how to communicate numbers in a clear, non‑technical way to business owners
• Contributing to client meetings, including preparing schedules, slides or notes
• Responding to client queries on day‑to‑day finance issues and system use
• Liaising with other experts on the client’s behalf to assist with other business issues (HR teams/lawyers/tax specialists/banks etc)
• Building awareness of wider commercial issues such as growth, funding, cash management and business performance
• Visiting client’s offices to engage with the wider team, not just the business owner
• Working closely with managers to free up their time by assisting with last minute or ad‑hoc tasks

There will be opportunities to progress in the business upon completion.

In this role you will be completing a structured two‑year training contract and Level 4 apprenticeship programme, during which time you will study towards the Level 3 and Level 4 AAT (Association of Accounting Technicians) professional qualifications. It’s designed to give you a strong foundation in accounting while gaining valuable hands‑on experience.

What this means for you:

• You will complete 10 AAT exams across key areas such as bookkeeping, financial statements and tax
• You will gain relevant work experience, supported by…
