How We Deliver Exceptional Charity Accounting Services?

We don’t just manage your finances—we optimise, protect, and empower your charity’s mission. Here’s exactly how we do it

Bespoke Compliance
Roadmap

Your dedicated CPA creates a 12-month action plan covering filings (Charities Commission, HMRC), Gift Aid claims, and fund allocation.

Cloud-Based System
Setup

We migrate your accounts to secure, real-time platforms (like Xero or QuickBooks) for seamless tracking of donations, grants, and expenses.

Hands-On Financial Health Check

Monthly reviews of your cash flow, VAT position, and payroll to spot risks or opportunities—like unclaimed tax reliefs.

Fraud & Governance
Audits

Our team implements automated fraud alerts and trains your staff on best practices to protect every penny.

Donor & Trustee
Reporting

We prepare plain-English financial summaries for stakeholders so they see transparency and impact, not spreadsheets.

Strategic Growth
Sessions

Quarterly meetings to align your finances with long-term goals, like scaling programs or securing major grants.

Full-Spectrum Charity Accountancy Services

Many non-profits waste time and funds navigating complex filings like Gift Aid claims, independent examiner’s reports, and trustees’ responsibilities—only to face avoidable penalties. At Sigma, our specialist charity accountants handle these intricacies for you, ensuring your non-profit accounts are audit-ready, tax-efficient, and fully aligned with your goals.

From setting up a charity with the right financial foundations to establishing reserves policies that protect your future, we go beyond number-crunching.
