How to hire an office administrator: sourcing channels, the admin, bookkeeping and front-desk skills to test, a practical work sample and red flags.

Applying for a role like this? Practise the assessment free →If you want to hire an office administrator, expect to hire a generalist: the person who handles the post, supplies, invoices, visitor sign-in, simple bookkeeping and IT requests in a small or mid-sized office. Because the job is broad, the hiring risk is finding someone who is good at one part and avoids the rest. This guide shows how to source, test the full range and onboard an office administrator.
Why this role matters
In many smaller organisations the office administrator is the only dedicated admin, so their reliability decides whether bills are paid, records are complete and visitors get a good first impression. They often hold the keys to suppliers, building access and basic finance. A careless hire can quietly cause late payments, lost documents and gaps in compliance records.
Where to find candidates
- Indeed, LinkedIn and local job boards, where most office administrators search
- Office staffing agencies offering temporary or temp-to-perm placements
- Business administration courses and apprenticeships at further education colleges
- IAAP and ASAP communities for candidates investing in their administrative careers
- Local business networks and chambers of commerce, useful for small employers hiring nearby
- Returners and part-time talent pools, since many office administrator roles suit flexible hours
Skills to look for
Red flags
- Avoids or dismisses the finance or facilities side of the job when you describe it

The interview process
- 1
Phone screen
Confirm which parts of office administration they have done before: finance, facilities, reception, HR records or IT. Ask what they enjoyed least so you can see whether it is a large part of your role.
- 2
Practical work sample
Set a few tasks from a typical week: match three supplier invoices to purchase orders and spot the one that is wrong, draft a reply to a landlord about a maintenance issue, update a staff contact sheet and plan an office supplies order within a budget. A job simulation of this real work is one option to keep the test identical for everyone.
- 3
Structured interview
Ask about a time they found a mistake in a payment or record, how they planned a week with no one to set their priorities and how they handled a difficult visitor or supplier.
- 4
Meet the team and references
Let the candidate meet the people they will support. Ask references about accuracy, reliability and how much they handled without being asked.

Common questions
What is the difference between an office administrator and an office manager?
An office administrator usually carries out the day-to-day admin, finance and facilities tasks. An office manager typically owns the office budget, policies and supplier decisions, and may manage the administrators.
Does an office administrator need bookkeeping experience?
If the role includes paying invoices or reconciling expenses, yes, at least with basic software. Test it with a short invoice-matching task rather than relying on the CV.
Can this role be part-time?
Often it can, especially in small offices. Be clear about which tasks are time-sensitive, such as post, deliveries or payment runs, when setting the hours.
What should an office administrator work sample include?
A mix of the real job: some invoice matching, a written reply to a supplier or landlord, a record to update and a small budgeting decision. Breadth matters because the role is broad.
