Job Description:
Do you have hands on all round accounting experience in a creative SME agency looking to join an already profitable start up and grow with them?
A new kind of integrated creative agency, built for a new era of marketing and founded on the belief that brands have the power to shape culture! The agency growth brought them to the point of hiring a permanent part - time Finance Manager supported by Fractional Finance Director. You will join the agency at a pivotal moment — perfect spot for someone who wants more than just a steady role, and is excited by the opportunity to help build something from the ground up.
This is a hands-on role with real ownership!
Working closely with our Fractional Finance Director and delivery teams, you’ll take charge of the day-to-day finance function while helping shape how finance supports a fast-growing, project-based business.
As the agency scales, you’ll play a key role in strengthening processes, improving visibility across projects, and enabling smarter decision-making across the agency.
You’ll sit at the heart of the business, combining financial control with commercial insight:
*Own monthly management accounts, reporting, and balance sheet reconciliations
*Support budgeting, forecasting, and short-term cashflow planning
*Ensure accurate project financials and monitor profitability across accounts
*Partner with delivery teams to improve financial discipline and commercial performance
*Oversee purchase and sales ledgers, supplier payments, and approvals
*Maintain accurate records in Xero and ensure strong financial controls
*Improve systems, processes, and reporting across finance and project tools
*Act as the go-to for day-to-day finance queries
The Person
*Proven experience in a Finance Manager (or similar) role
*Experience in a creative, agency, or project-based environment is a plus
*Strong technical finance skills with a sharp eye for detail
*Commercial mindset — you understand how projects drive profitability
*Confident working with non-finance teams
*Comfortable operating independently in a growing business
*Experience with Xero (or similar); agency tools like Synergist or Paprika a bonus
*Strong Excel / Google Sheets skills
This is a rare chance to join at the ground floor of an ambitious agency and help shape how it grows.
You won’t just be reporting numbers — you’ll be influencing how the business runs, scales, and succeeds.
If you’re looking for ownership, variety, and the chance to build something meaningful from day one, we’d love to hear from you.
