Four industries we specialise in. Each with its own challenges, its own tax angles, and a team that understands the detail.
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.
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.
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.
NI professional services firms have specific accounting needs that general practice accountants often miss. Practice structure, partner remuneration, WIP and lock-up management, and succession planning all require specialist knowledge.
One fixed annual fee covers everything your business needs to stay compliant and ahead of HMRC. Just £1,499+VAT/year for total peace of mind.
Accounts, self-assessment, quarterly VAT, payroll for up to 5 staff, and ad-hoc tax advice. All included.
Twenty-five years in Belfast. We answer to the same standards as the big firms, with the relationships only a local firm can build.
Year-end is too late. We talk to you all year round about tax planning, growth, and the decisions that move the bottom line. Your accountant should be your most useful adviser, not your most expensive filing service.
We agree the scope and the fee upfront. No hourly billing. No surprise invoices. If anything changes we tell you before any work happens. The same clarity we bring to your accounts, we bring to ours.
A 22-person engineering firm in Lisburn had been told by their previous accountant that R&D tax relief did not apply to manufacturing. It does. We reviewed three years of qualifying activity, prepared the claim, and handled the HMRC correspondence. The credit landed in their bank account 11 weeks later.
