Case study – small business support
Mark is thriving with Fusion’s small business support
A small business owner came to Fusion overwhelmed by cashflow uncertainty and time-consuming bookkeeping. Our team introduced digital systems, delivered clear monthly reports, and provided proactive tax planning. With this support, they gained visibility on profitability, reduced overheads, and made confident reinvestments. What once felt like a constant financial worry became a structured roadmap for growth. They described Fusion as “the partner that turned accounting from a burden into a tool for success.” Today, their business is stronger, more profitable, and positioned to grow sustainably with the confidence to plan years ahead instead of just month by month. They now rely on Fusion for ongoing support, from payroll to compliance, giving them the freedom to focus fully on expansion.
Fusion Accountants gave me the clarity to finally focus on running my business instead of firefighting finances.

Seamless Support from Trusted Chartered Accountants
At Fusion, you’re not just getting compliance — you’re gaining a partner. As ICAEW chartered accountants, we provide expert advice backed by over 30 years of experience working with small businesses across London and the UK.
Every client is matched with a dedicated accountant who knows their business inside out, supported by a wider team for specialist advice. From managing your bookkeeping in Xero or QuickBooks to preparing tax returns and payroll, we make sure everything runs smoothly and on time.
But it doesn’t stop there. Our proactive small business accountants check in regularly to offer tailored advice, ensure your financials are always up to date, and support you as your business grows.
Research & development tax relief for small businesses
Many small businesses don’t realise they qualify for R&D tax relief — a government incentive designed to reward innovation. If your company is developing new products, processes, or technology, you could claim back a significant percentage of your costs, improving cashflow and freeing up money to reinvest in growth.
At Fusion, our accountants work with you to:
- Identify qualifying R&D activities and expenses – We review your projects and highlight which parts of your work meet HMRC’s innovation criteria, from new product development to improvements in systems or processes.
- Prepare and submit claims in line with HMRC requirements – Our team gathers the evidence, calculates your eligible costs, and ensures your claim is submitted accurately and on time.
- Maximise your relief while ensuring full compliance – We look at all allowable expenses to increase your claim value, while keeping everything fully compliant with HMRC’s rules and audit standards.
Even if you’re not in traditional “tech” industries, you may still qualify — businesses in construction, manufacturing, healthcare, and digital sectors regularly benefit.
Customer service reviews
Fusion guided me through the whole process including putting one employee on the payroll and then when it came to my annual tax return completed this in an efficient and timely manner. Many thanks in particular to Deepti Christian for her always professional service.

Companies with profits up to £50,000 pay 19%
-
Profits between £50,001 and £250,000 are taxed at a tapered rate

Profits over £250,000 are taxed at the main rate of 25%
Limited companies do not pay Income Tax or National Insurance on profits—but directors may owe personal tax on salary or dividends taken from the business.
