Job Description: Client Accounts Administrator

£25,000 to £26,000 · Full time, 37 hours · Remote (UK), with our Cardiff office there whenever you want it

About agentOS

We make software that helps letting agents run their businesses, and through agentPay we look after the accounts side for many of them. We're a team of around 22 based in Cardiff, small enough that your work gets noticed, and part of a larger software group that gives us stability.

Why this role matters

Letting agents trust us with their clients' money. This role keeps their accounts accurate, their payments on time and their month-end running smoothly, so they can focus on running their business with confidence.

What you'll do

• Keep clients' account information up to date and reconcile their bank statements in agentOS
• Process payments for clients, including payment files, invoices and payments to organisations such as HMRC and the Deposit Protection Service
• Chase outstanding arrears by phone, email, text and letter
• Prepare client statements and help clients through their month-end
• Help clients stay compliant, flagging any risks you spot
• Train clients on agentOS, including setting up new accounts clients
• Check in on how clients' accounts are doing, rather than waiting for problems to come to you

What we're looking for

You don't need experience in accounts or lettings. We'll train you. What matters is that you:

• Are comfortable with numbers and careful with detail, because this is our clients' money
• Stay calm and clear on the phone and by email, including when chasing payments
• Keep on top of deadlines, especially at month-end
• Are comfortable using AI tools and picking up new software quickly
• Know when to ask for help, and aren't afraid to

Where it can lead

This role opens several paths, depending on your interests and how you develop: Client Account Manager, Team Leader, Client Accounting Specialist, or Advanced Accounts.

What you'll get

• £25,000 to £26,000, depending on experience
• 28 days holiday plus bank holidays, rising with length of service
• Work remotely, or use our Cardiff office (free parking, social spaces and a wellbeing room) whenever you like
• 24-hour private GP access
• Employee assistance programme with counselling, plus a wellbeing app
• Workplace pension
• Enhanced maternity pay
• Regular social and company events

We'll review applications as they come in and may close the role early, so don't wait. If you need any adjustments to apply or interview, just let us know.
