About Cratus

Cratus Group is a leading communications consultancy, providing integrated strategic communications and campaigns across multiple sectors. Founded in 2009, we’ve helped some of the UK’s best known brands deliver local and national campaigns, manage political and reputational risks, and influence national policy on some of the most important issues facing the UK. What we do matters. We’re more than just an agency. We’re change makers.

About the role

We are looking for a diligent and organised Part-Time Finance Assistant to join our team. This is a great opportunity for someone who enjoys working behind the scenes to ensure smooth financial operations in a busy, dynamic agency environment.

You will be supporting our finance function on a part-time basis (3.5 hours per day, over a 5 day working week), working closely with senior staff to assist with accounts, invoicing, bookkeeping, expense reconciliation and general financial administration. The successful candidate must be able to attend our Central London office to support the finance team and wider business.

Key responsibilities will include

  • Processing and recording invoices and receipts
  • Assisting with expense tracking and reimbursement cycles
  • Supporting bookkeeping and basic account maintenance
  • Helping prepare simple reports and financial summaries
  • Liaising with colleagues to chase outstanding payments / manage incoming invoices
  • Supporting payroll input and timesheet monitoring (if required)
  • General administrative support to the finance team

What we’re looking for

We welcome applications from candidates with a range of backgrounds – whether you have prior finance or accounting experience, or are looking to develop your skills in a supportive agency setting. The main things we want are:

  • Strong organisational and numeric skills
  • Good attention to detail and accuracy
  • Confidence using spreadsheets (e.g. Excel) and basic accounting software (Xero experience is a plus or willingness to learn)
  • Ability to work independently, organise your own workload and take initiative
  • Good communication skills and ability to liaise with different team members
  • A flexible, proactive and collaborative mindset

Previous experience in an agency, small business, or administrative role is a plus but not essential.

In return we offer a comprehensive benefits package

  • 28 days annual leave pro rata plus:
    • Bank holidays
    • Birthday day off
    • Charity volunteering day
  • Central London office with:
    • Good coffee / free snacks
