Your time back
Hand over the admin. Keep the decisions.

Bookkeeping and bank reconciliations
VAT returns, if you're registered
Year-end accounts and Corporation Tax
Your self-assessment tax return
Companies House filings
Payroll, if you have a team (quoted extra)
You focus on
Winning and looking after customers
Pricing, hiring and what to do next, with real numbers in front of you
Deciding what to pay yourself, knowing what the business can afford
Your evenings and weekends

Your year-end accounts tell you what happened. These tell you why. On Growth and Strategic, your management accounts track the ones that matter for your business, explained in plain English.
01
Profit
What the business really made once every cost is counted, not just what landed in the bank.
02
Cash flow
When money comes in and goes out, so a quiet month or a big bill doesn't catch you out.
03
Tax to set aside
How much of the money in your account is really owed to HMRC, so tax bills don't come as a surprise.
04
What you can pay yourself
How much you can safely take out of the business without leaving it short.
05
Gross margin
What's left from each sale once its direct costs come out, so you can see which work really pays.
06
Money owed to you
Who owes you, how much, and how long they're taking to pay.
Every plan gets your filing done. Higher plans add insight.
Your fee depends on your business, so we agree it on your first call: one fixed monthly fee, reviewed with you every six months so it follows your business in both directions. Pay for the year upfront and it stays fixed for the whole year.
Strategic
A true financial partnership.
Your finance team without the headcount. Budgets and forecasts, so you manage against a plan instead of only looking back.
Shown for a limited company. Sole traders and partnerships are covered too, with the filings that apply to them. Optional extras, quoted upfront: a tax planning review, payroll, company formation and cloud accounting setup. Fractional CFO support is available once you've been with us for 12 months.
Your year-end accounts and corporation tax are included once you move onto the full plan. You're covered by a money-back guarantee, as long as you reply quickly, turn up to your meeting, and do your part. Full terms are in the agreement. Both offers are available until 31 December 2026.
Trading for more than two years? You don’t need an offer. Book a call and we’ll handle the switch from your current accountant.
Keiran Hirst Founder
Who you’ll work with
Swap the feeling for the figures.
Keiran founded Aethon after working across several small-town accountancy practices with hundreds of small businesses. The pattern he saw most often was owners running on a feeling about how the business was doing, rather than the real numbers, and that feeling was often wrong in both directions.
“You didn’t start your business to become a bookkeeper. You do what you’re good at, and I’ll do what I’m good at.”
How does switching from my current accountant work?
You let your current accountant know you're moving, and we handle the rest: the professional clearance letter, getting your records across, and moving your HMRC agent authorisations over. If your current accountant has a notice period, we'll plan the switch around it so nothing falls through the gap.
How much does it cost?
One fixed monthly fee, agreed before we start. It's based on the size of your business and what you need from us, not on hours. There's no joining fee and no exit fee. Software setup, like moving you onto Xero, is quoted upfront if you need it. Anything extra, like catching up a backlog, is agreed before we start. We review your fee with you every six months, so it follows your business in both directions. If you pay for the year upfront, your fee is fixed for that whole year.
Who do you work with?
Owner-run UK businesses that want to understand their numbers, not just file them: limited companies, sole traders and partnerships, from their first year of trading onwards. We also run a dedicated service for SaaS and software businesses.
Is there a minimum term? Can I leave?
On our monthly plans, you can leave by giving three months' notice, and there's no exit fee. New business offers and pay-yearly plans cover the period you've paid for, and your proposal sets out the terms. Whenever you leave, we'll hand everything over properly so your next accountant can pick up cleanly.
Do I need to change my software?
We work in Xero and QuickBooks. If you already use one, we'll work in yours. If you're on spreadsheets or something else, Keiran can move you onto cloud accounting as a quoted extra, with bank feeds and a receipt app set up so most of your transactions reach us without you sending anything.
What are management accounts, and do I need them?
A regular report showing your profit, your cash and the numbers that matter for your business, with a plain-English explanation of what it means. They're included in Growth and Strategic, monthly or quarterly depending on what you need. If you only need your filing done, Essentials covers that.
How easy is it to get hold of you?
You'll have a named accountant and a secure client portal, where you can ask as many questions as you like at no extra cost. You'll also have review meetings through the year. If you'd like us to research and set something up for you, we'll quote it first.
Do you only work with local businesses?
No. We're based in Bradford and work online with businesses across the UK, so it doesn't matter where you are.
