LumenStream: How Management Accountancy turns financial complexity into strategic decisions

 - Case Study

When LumenStream, a Northern Ireland-based energy technology company, began preparing for a seed investment round, it quickly became clear that traditional accountancy support wasn’t enough.

Customer Testimonial

“Ekstra has demonstrated a remarkable commitment to understanding our business, going far beyond a superficial overview. They have invested considerable time and effort in learning the intricacies of our operations and accurately assessing our position on the growth curve.”

Alistair Brown, Founder, LumenStream

Introduction

The company had worked with a local accounting firm, which had provided year-end accounts, which focused exclusively on compliance. The service offered no meaningful analysis or explanation of the figures. As a result, the founder lacked confidence in the numbers being provided and realised that this would not be satisfactory going forward

For a start-up entering a critical phase of growth, that uncertainty was more than inconvenient; it was holding the business back.

Without up-to-date management information or insight into the company’s financial position, LumenStream risked losing credibility in front of investors. The team needed a management accountant who could provide more than HMRC-ready numbers; they needed a strategic partner who could explain the story behind those numbers, guide decision-making, and create the financial structure necessary for scaling.

The Challenge

The timing could not have been more critical. LumenStream was preparing to raise external investment while still establishing its internal processes. Without solid financial foundations, securing investment and managing future growth would be increasingly difficult.

The founder, Alistair Brown, needed:

  • A reliable management accounting service that accurately reflected the company’s position month-to-month.

  • An accountant who can forecast figures to test different growth and funding scenarios.

  • Clear, data-backed accounts insight into cash flow, profit margins, and investor readiness.

  • A flexible management accountant who could communicate in plain English, helping translate financial information into strategic business decisions.

In short, the business needed a virtual finance director,a proactive partner who could act as a financial sounding board and provide oversight, without the cost of hiring an in-house Chief Financial Officer of Financial Director

The Solution

LumenStream was referred to Ekstra Accounting Services through a business advisor and a shared local network. From the outset, our focus was on developing a deeper understanding of the company’s operations, its growth curve, and the expectations of its investors.

Ekstra Accounting Services provides management accountancy, business advisory, and outsourced finance services to SMEs and scaling businesses across Northern Ireland. Our approach is built around partnership, embedding financial insight at the heart of a client’s strategy.

For LumenStream, this meant moving from simple compliance to strategic clarity.

We began with a detailed review of the company’s existing financial systems, reporting processes, and investment documentation. From there, we designed a bespoke outsourced finance function tailored to the needs of a growing technology firm.

The solution included:

  • Monthly Management Accounts – providing accurate, timely and meaningful reporting on performance, growth, and cash flow.

  • Forecasting and Financial Modelling – creating dynamic forecasts to support funding rounds and investor communication.

  • Virtual Finance Director Oversight – ensuring strategic alignment between financial decisions and business objectives.

  • Integrated Outsourced Finance Team – managing bookkeeping, payroll, and reporting processes in a single streamlined structure.

  • Business Advisory Support – working directly with the founder to interpret financial data and use it to inform planning.

  • Education and Empowerment – helping the founder understand financial principles to confidently communicate with stakeholders.

Client testimonials
Janet has been a great asset during the first year of running my business. Easy to work with, helped me when I needed help and advice. It's really reassuring that I know who I'm going to be speaking to on the phone or email and not getting passed round an office.

My end of year has just been completed with no dramas or panic and I know that was because she helped me get set up the right way rather than letting me go down the wrong path at the start.

Would definitely recommend.

Patrick Wood

It was a great bonus to have Janet referred to me. Janet is a very knowledgeable accountant and explained everything that I needed to know about my accounts. Extremely diligent, dedicated and professional at all times.

Paulene Anderson

Engaging Ekstra Accounting Solutions has given me peace of mind about my business finances. Janet has been very professional and always there for help and advice when needed. I no longer stress about year end, quite the opposite, such is my faith in Janet doing an excellent job I have been motivated to have everything ready to hand over very soon after 5th April. I would highly recommend her to anyone seeking efficiency and professionalism from their Accountant.

Sandra Parry

Janet was excellent. Very prompt replies to emails, explained everything to me and was able to get a fairly complicated case resolved very quickly. I would highly recommend Ekstra Accounting Solutions.

Sarah Donelly

Ekstra Accounting Solutions helped me get my business back on track financially in every sense especially with VAT. My company was deregistered for vat in error by HMRC. As a result, I lost my VAT number which meant that my company could not claim any VAT back on imports for about 18 months. This impacted my business substantially and I struggled to find someone to help me resolve this issue. Janet took my company accounts and sorted everything out which was no mean feat. Janet even assembled a team of specialists to advise on how best to address the VAT issue. The end result is my company is now back on track and fully compliant with HMRC. Thank you so much Janet you’re a star, I am truly grateful that this is no longer hanging over me and my business.

Martyn Watters

Janet has provided such invaluable advice and support, which has been greatly appreciated! As the treasurer of a newly established Northern Irish charity, the world of HMRC, corporation tax and Companies House is completely new to me. The experience and expertise of Ekstra Accounting Solutions in helping us prepare our end-of-year accounts was so reassuring to myself and the Board, and I wouldn't hesitate to use their services again or to recommend their services to any other charities or business! Thanks so much Janet for your support, your willingness and interest in helping a new charity and for calming my nerves!

Leslie Altic

Janet reached out to me online after I posted on Social media looking for an accountant. She made the whole process comprehensible and uncomplicated, which is what I was looking for. She is very responsive and easy to get a hold of when I need help. If you're looking for an accountant, one who is composed and friendly, I'd recommend contacting her. Thanks

Janet's professionalism and dedication in converting our Church accounts from simple spreadsheet format to Charity Commission Northern Ireland format has been exceptional. It has been a pleasure to work with her.

Janet offers a friendly, professional and well informed accountancy service. Nothing is ever to much trouble and in the relatively short time I have been with her, she has saved me both time and money. I cannot recommend Ekstra Accounting Solutions highly enough!

Ian Roddy

What a treasure we found when Janet appeared on our radar! From the initial contact to the accounting business support we now have, Janet has been so supportive. As a charity our accounts can be quite tedious but Janet has been so knowledgable in setting up and managing our accounts. She enabled us to take our bookkeeping and financial recordings to a whole new level in Xero.
I highly trust and recommend her services!
