Management Accounting

  • Overview

    At each stage of a business’ life cycle an effective finance function should look after the day-to-day processing whilst supporting management with timely, accurate and relevant reporting.

    Although the cost-effective nature of outsourced accounting initially attracts many of our clients, it’s the elimination of hiring costs and access to a high quality and variable type of resource (on a permanent or short term basis) which ensures an Isosceles solution continue to work as our clients’ scale.

  • Transaction processing

    Accurate day-to-day processing is the foundation of strong management reporting.  Errors at this point of entry undermine reporting and can lead to misinformed decision making.

    When you take an Isosceles outsourced accounting solution we will manage all transactional processing to include, purchase and sales ledger processing, credit control and payment runs, management of bank transactions and ownership of all financial transactions.

  • Financial control

    We understand that every company is different.  Isosceles will create a bespoke control environment to include best practice accounting policies and procedures which maximise the security and control of resources without choking day-to-day operations.

    Isosceles’ financial control procedures ensure all purchases have been through the correct process, that all invoices are matched to orders and authorised prior to payment. We also ensure appropriate supplier agreements and customer contracts are in place prior to the commencement of works, and review contracted terms and conditions.

  • Business Intelligence Reporting

    Timely, accurate and relevant reporting helps drive the accountability of staff, increase visibility of performance and support informed management decision making.

    Having determined the nature, frequency and format of your financial reporting, Isosceles can incorporate KPI’s and trend analysis and communicate business performance via our visual analytics dashboard. Our support won’t stop with the delivery of a report. We sit with your senior management team to help them understand, interpret and act upon the information provided

  • Financial Forecasting

    Cash is the blood of a business, even the most profitable can suffer cash flow shortages. Through our financial forecasting models Isosceles will help you understand working capital requirements and identify short and long-term pinch points and gaps.

    Through quarterly, annual and 3-year forecasting we can identify your working capital needs so can take steps to address funding.  Whether it’s banking facility negotiations, grant and funding applications or weighing up the pros and cons of alternate sources of finance, we can help.

  • Payroll

    A motivated business needs motivated people. Ensuring employees are paid on time and correctly is a basic requirement every business should meet.

    With an ever-increasing HMRC reporting burden our payroll team will also make sure you remain compliant and up to date with all changes in law and statute.  Our outsourced payroll service is an efficient, dependable and affordable alternative to running your own in-house payroll system.


Financial Planning

  • Overview

    A realistic business plan helps identify your targets and goals and sets out how you will navigate towards them.

    Isosceles’ outsourced accounting service will help you get where you want to be.  We will provide an honest and frank assessment of your current position, benchmark this against your aspirations and help you get there.

  • Finance operation review

    The closer you are to your business, the more difficult it is to remain objective when critiquing systems, reporting and processes.

    Isosceles are independent and impartial. A finance operation review doesn’t need to interfere with day-to-day operations, or distract your FD or CFO from supporting the management team.


    Isosceles will work with you to rigorously review the

    • Effectiveness and efficiency of the finance operations
    • Processes and procedures for adequacy and effectiveness
    • Level and competency of the financial resources
    • Capability of the current finance systems
    • Robustness of the financial controls
  • Financial planning, budgeting and forecasting

    As growth opportunities present themselves, companies must anticipate risks and opportunities and adapt their plans to achieve their growth targets.

    Without critical review and realistic, knowledgeable input a financial plan, forecast or budget can end up as nothing more than a set of numbers on a spreadsheet, an unachievable wish list of managements ideas, without foundation in reality.


    Isosceles can help you to develop comprehensive financial planning which identifies and communicates your business’s strategic objectives.

    We can drive the annual budgeting process and build an interactive profit and loss, balance sheet and cash flow model which creates both a high level overview and a detailed month by month breakdown.

    Having created a budget or forecast it is crucial to review your performance against it and regularly update it for changes in your environment and knowledge. Isosceles can flex your forecasts to track actual performance and revised expectations and model additional analyses if required, to help benchmark the current forecasts against your longer term targets.

  • ‘What if?’ scenario modelling

    ‘What if?’ scenario modelling can significantly reduce uncertainty and risk.

    By examining the differences between varying outcomes and scenarios “what if?” analysis is a powerful tool to aid the understanding and identification of key business decisions and their effect on your business.


    We can help you to determine which ‘what if?’ questions are appropriate to your business and run financial simulations. This will reveal the potential impact of each scenario and help you plan an appropriate course of action.

    ‘What if?’ scenario modelling will:

    • Demonstrate the strength of your business plan to investors
    • Help to develop a ‘Plan B’, equipping you to respond rapidly
    • Stimulate new business growth potential by forcing you to think creatively, removing the constraints of normal corporate thinking
    • Help you to prepare a compelling exit strategy, demonstrating the resilience of your plan and maturity of your business skills to potential acquirers

Statutory accounting, tax and compliance

  • Overview

    Modern statutory accounting and taxation obligations are constantly changing and becoming more complex, with ever increasing fines and penalties for non-compliance.

    Isosceles can provide specialist statutory accounts and tax services and will ensure that your statutory obligations are met

  • Statutory accounts

    Every company is required by law to prepare and file an annual set of statutory accounts with Companies House.

    At the end of your financial year, we can produce your financial statements, and both abbreviated and full accounts as required.  For your convenience and peace of mind, we will also file the accounts with Companies House in line with relevant filing deadlines.

  • Company secretarial

    Many companies underestimate the role of company secretary and pass the responsibility for statutory compliance to an over-burdened, under-qualified member of staff.

    Outsourcing your company secretary services to Isosceles is the safe solution. We can help with all levels of service, from a basic service for start-ups and small companies, to a comprehensive package for large companies facing complex structural change and on-going compliance.

  • Corporate tax

    • Have the most tax-effective structure for your business
