About us

We love helping people get to where they want to be.

Complete HQ started with a simple frustration: too many brilliant businesses were stuck with accountants who only showed up once a year.

So Andy Sullivan built the firm he'd want to hire: proactive, straight-talking, Xero-first and on fixed fees. Today we're the finance team ambitious founders and growing businesses plug into.

Our mission

What we stand for

Challenge boundaries

The way it's always been done isn't a reason.

Focus on what you love

You run the business. We handle the numbers.

Be honest

We tell you straight, even when it's not what you want to hear.

Be cool, be kind

Good people, good work, good fun.

Andy Sullivan

Founder & MD

Andy Sullivan

Andy has 22 years' experience in finance. He specialises in CFO and business strategy work for SMEs and investment-backed startups. After working his way from apprentice to director and shareholder at his previous firm, he founded Complete HQ to give ambitious businesses a finance partner who gets involved, not just an annual set of accounts.
