Launching a start-up? Don’t let accounting headaches slow you down. Our expert business accountants specialise in start-ups—handling everything from company formation to VAT, payroll, and cloud accounting (Xero/QuickBooks/FreeAgent). Limited company, sole trader, or LLP? We’ve got you covered—so you can focus on what really matters: growing your business.
Most startups launch with big ideas but zero financial infrastructure. Founders juggle cash flow nightmares, HMRC deadlines, and investor demands—all while trying to grow. The result? Costly mistakes: overpaid taxes, payroll errors, missed R&D claims, or worse—compliance penalties that drain precious runway. Many DIY at first (or hire the wrong accountant), only to realise too late that poor financial hygiene slows funding, scaling, and even survival.
This is where Sigma steps in. We don’t just file your taxes—we build financial systems tailored to startups. From day one, we automate payroll/VAT, optimise tax structures (so you keep more revenue), and ensure investor-ready reporting. Our fixed-fee plans scale with you so you avoid surprise fees. Think of us as your on-demand finance team: proactive, tech-savvy, and obsessed with saving you time and money.
Your finances need to be as agile as your business. From tax compliance to investor readiness, our tailored accounting services handle the numbers—so you can focus on scaling.

Raising funding isn’t just about great ideas—it’s about proving your startup’s financial credibility. Investors need to see bulletproof forecasts, airtight compliance, and scalable systems before writing checks. Yet most founders struggle with patchy financial controls, unclear runway projections, and last-minute scrambles to meet due diligence demands. One missed compliance requirement or unrealistic cash flow model can derail your entire funding round.
Think of us as your co-pilots for fundraising—we don’t just prepare your numbers, we strengthen your entire financial position to secure capital on better terms.
Beyond compliance, we identify opportunities—whether it’s tax savings, funding readiness, or financial process optimisation—to fuel your scaling journey.
