Clear advice. Sound judgment. No jargon. We work alongside NI business owners to turn complex figures into confident decisions.
Accountants for Small Business Owners and Entrepreneurs
We work with business owners who want more from their accountant than a year-end filing. Our team is trained to think commercially, communicate plainly, and distil complex information down to what is most important.
We provide tailored guidance you can act on, exercise sound judgment on the decisions that matter, and make sure nothing falls through the cracks. No surprises. People who pick up the phone.

Sectors we know inside out
We work with businesses across every NI industry. These are the sectors where we have built the deepest playbooks. See all sectors →
Construction
Construction is the most paperwork-heavy industry on the books. CIS deductions, VAT reverse charge, retentions, applications for payment, and a workforce that flexes by the project. We work with NI builders, contractors, and subcontractors who need their accountant to know the difference between an application and an invoice.
Hospitality
NI hospitality runs on margin, footfall, and the cost of the next shift. From independent restaurants in Belfast to multi-site pizza, coffee, and quick-service operators, we work with hospitality businesses who need an accountant that understands tronc, tips, and what a wet weekend does to the till.
Retail
NI retail runs on margin, footfall, and seasonal cash flow. From independent shops in Lisburn to multi-site operators across Belfast, we work with retailers who need their accountant to understand the rhythm of a till-driven business.
Manufacturing
Northern Ireland has one of the strongest manufacturing bases in the UK, from aerospace and engineering to food processing and advanced materials. We work with manufacturers who need an accountant that understands the difference between a balance sheet and a shop floor.

Not-for-profit Charity SORP, audit thresholds, and governance for NI charities and CICs.
NI charities, social enterprises, and community interest companies operate under their own legislation and their own regulator. You need an accountant who knows the Charities Act (NI) 2008, not just the England and Wales version.

Property & landlords Section 24, MTD-ITSA, and incorporation decisions for NI landlords.
Owning property in NI has changed beyond recognition since 2017. Section 24 mortgage interest restriction reshaped the maths for higher-rate landlords. Furnished Holiday Let status changed in April 2025. Making Tax Digital for Income Tax lands in 2026 and 2027 with quarterly filings. We help individual and portfolio landlords across NI navigate the decisions that actually move the tax bill.

Healthcare practices Associate vs principal, goodwill, and NHS income for NI healthcare practices.
Healthcare practices have their own tax language. Associate versus principal income, goodwill on acquisition or sale, mixed NHS and private income with different VAT treatment, and ownership structures shaped by partnership law and professional regulation. We work with dental, GP, vet, pharmacy, and optometry practices across NI on the accountancy that fits the way the sector actually runs.

Professional services Partnership accounts, WIP, and profit shares for NI legal, architecture, and consulting practices.
Professional services firms run on partner time, WIP, and reputation. The accountancy is partnership-heavy: profit-share waterfalls, partner capital accounts, work-in-progress that ties up cash, and tax positions that vary widely between equity partners, fixed-share partners, and salaried partners. We work with solicitors, architects, surveyors, and consultancy firms across NI.

Technology & software R&D tax relief, EMI options, and SEIS/EIS for NI tech founders and SaaS businesses.
Tech and software businesses have a specific set of tax tools available. R&D tax credits, SEIS and EIS for early-stage funding, EMI share option schemes for retaining staff, and corporate structures that scale into international markets without creating tax friction. We work with NI tech founders, SaaS businesses, agency-style dev shops, and managed service providers.

Trades & home services CIS, van and tool capital allowances, and sole-trader to limited transitions for NI trades.
Trades are CIS-heavy, van-heavy, and tool-heavy. The accountancy is mostly about three things: getting CIS right, claiming everything you have spent on plant and vehicles, and knowing when to make the jump from sole trader to limited company.

Hair, beauty & personal services Chair rental, MTD-ITSA, and sole-trader transitions for NI personal-services businesses.
Personal services is the most overlooked corner of accountancy. Hairdressers, barbers, beauticians, nail techs, lash artists, mobile therapists, and personal trainers. High volume, mostly cash or app-paid, and almost always under-served by generalist accountants. We work with salon owners, chair renters, and mobile practitioners across NI on the questions that actually shape what they take home.

Agri-food & farming Herd basis, farmers’ averaging, and capital allowances for NI farms and food producers.
NI farming and artisan food production has its own tax toolkit. Herd basis, farmers’ averaging across two or five years, Agricultural Property Relief, capital allowances on farm buildings, and a stream of grant schemes that need careful accounting treatment. We work with farms, food producers, and craft drinks businesses across NI.

Logistics & haulage Vehicle capital allowances, driver payroll, and cross-border VAT for NI hauliers.
NI hauliers and freight businesses sit at a unique tax junction. Cross-border movements with the Republic and Great Britain bring multiple VAT regimes into play under the Windsor Framework. Fleet capital allowances at scale, driver payroll, and fuel and AdBlue accounting dominate the cost base. We work with owner-driver hauliers, small fleets, couriers, and freight forwarders across NI.
