Part-Time  | £20–£25 per hour

AdminOS is redefining how growing businesses manage their back-office operations. We provide high-quality, outcome-focused administrative support to fast-moving US-based companies—from financial workflows to executive support and operational coordination.

We’re looking for a UK-based Finance Assistant with strong attention to detail, excellent communication skills, and experience supporting finance teams or business owners. You’ll work remotely, embedded into client businesses, helping them maintain financial clarity and consistency.

This role starts as a part-time contract based on your weekly availability, but we have the demand to quickly scale you up to full-time hours if desired. Our model is flexible—meaning we can increase or reduce your hours based on client needs and your preferences. You choose your capacity, and we manage the rest.

What You’ll Do

• Process invoices and track accounts payable/receivable
• Reconcile transactions and support expense tracking
• Manage shared finance inboxes and approval flows
• Assist with monthly reporting, bookkeeping tasks, and documentation
• Communicate clearly with clients and internal teams to maintain workflow accuracy
  

What You’ll Need

• 2+ years in a finance admin, accounts assistant, or bookkeeping role
• Confidence using tools like Xero, QuickBooks, or similar platforms
• Strong organisational skills and ability to work independently
• Experience supporting SMEs or high-growth businesses preferred
• Comfortable working remotely with distributed teams
• Ideally, some exposure to US-based accounting 
• Your own laptop and high-speed internet
  

Why AdminOS

• Fully remote and flexible
• Competitive hourly rate
• Work with high-calibre clients in tech, finance, and services
• Be part of a structured, professional admin model—not a VA platform
• Ongoing support from Delivery Managers and a collaborative admin community
