Ongoing admin & back office · London
I provide ongoing administration and back-office support for small and growing UK limited companies that already have an accountant — but nobody taking ownership of everything around them.
From construction and trades to clinics, professional services and family businesses, I keep the documents, deadlines, finance administration and day-to-day back office moving.
No preparation. No obligation. Just a straightforward conversation about what's currently landing on your desk.

There is nothing to prepare. We spend around 20 minutes talking through what's currently sitting with you, what your accountant already handles and what you would like to hand over.
Afterwards, I send you a clear scope showing what I can take ownership of, what stays with your accountant and how the ongoing support would work.
Once we agree the scope, I organise the handover around the systems you already use. That means getting the right access, bringing documents and records into order, setting up a clear deadline calendar and establishing how information will move between you, Aventress and your accountant.
You do not need to build a perfect system before we start.
I keep track of deadlines, outstanding documents, finance administration and the recurring work we have agreed. You receive a clear update on what has been completed, what is still in progress and anything that genuinely needs your decision.
Instead of remembering the administration yourself, you stay involved only where your input is needed.
£30,000+ a year plus NI, pension, holiday cover and recruitment time.
For a larger business with enough ongoing work to justify a dedicated internal role, employing an office manager can make sense.
For a smaller company, however, it can mean taking on the cost and responsibility of a full-time employee before the workload actually requires one.
Cheaper per hour, but you supply the UK compliance knowledge — and the supervision.
A general VA can be a good fit for diary management, inbox support and clearly delegated tasks.
The difference appears when the work involves Companies House, VAT and PAYE administration, accountant liaison or recurring company deadlines: you need someone who already understands what the documents and processes are for.
Free until it isn't — a missed filing date, a late invoice, another weekend gone.
Doing it yourself avoids another monthly cost, but the administration still consumes your attention.
Every document you have to find, deadline you have to remember, invoice you have to chase and accountant email you have to deal with is time taken away from the work only you can do.
There is no recruitment process, no employee to train and no list of individual admin hours for you to keep allocating. The goal is simple: the administration becomes something I own, rather than something you keep remembering to delegate.

I have more than 10 years' experience working with the administration behind UK companies, including VAT and PAYE administration, CT600 supporting information, Companies House work and the day-to-day processes that keep a business organised.
I work best with business owners whose companies have reached the point where the administration can no longer simply be fitted around everything else — but where employing a full-time office manager still does not make sense.
I created Aventress because I kept seeing the same gap: accountants handle the accounts, business owners run the company, but nobody takes proper ownership of everything in between. That is the part I take care of.

No. I provide administration and back-office support, not accountancy or tax advice.
I prepare and organise information, keep administrative processes moving and liaise with your accountant. Your accountant remains responsible for tax returns, statutory accounts, tax advice and professional sign-off.
My support is designed for ongoing work rather than one-off tasks. Our agreement sets out exactly what is included and the notice period, so both sides know where they stand from the beginning.
Notice period: [CONFIRM]. Minimum term, if any: [CONFIRM].
Business information is treated as confidential and access is limited to what is needed to provide your agreed support.
Documents are handled using [CONFIRMED SYSTEM/STORAGE METHOD], with [CONFIRMED ACCESS/SECURITY MEASURES]. When our work together ends, information is retained, returned or deleted in accordance with the agreed terms and applicable data-protection requirements. ICO registration: [ADD IF APPLICABLE].
Yes. That is exactly how I work. You keep the accountant you already trust. I organise and prepare the administrative information they need, deal with routine communication where appropriate and keep track of anything outstanding.
Your accountant continues doing the accounting. I keep everything around it moving.
You do not need to organise your paperwork or prepare a list before getting in touch. Tell me what keeps landing back on your desk, what your accountant is regularly asking you for and which parts of the administration you would most like to stop handling yourself.
We'll have a straightforward conversation about what I could take over. If it isn't the right fit, I'll tell you.
