Sound familiar?
Your accountant files. That is all.
A lot of London small businesses pay for an accountant and hear from them once a year, usually just before a deadline. The books are behind, the tax bill is a surprise, and no one has mentioned what you could have done differently six months ago. That is not an accountant. That is a filing service.
- ✕ Year-end arrives and the tax bill is news to you
- ✕ Books are months behind and catching up takes all weekend
- ✕ VAT returns, payroll, and deadlines managed in a panic each quarter
What being on top of it looks like
Your compliance runs on schedule. Your tax position is visible in advance. When something changes — IR35, a threshold, a relief you can claim — you hear about it before it becomes a problem.
- ✓ Your tax liability estimated and explained well before HMRC asks
- ✓ Monthly bookkeeping current, cloud-based, and reviewed regularly
- ✓ VAT, payroll, and filing deadlines handled without you chasing anyone
- ✓ One fixed monthly fee covering the scope agreed — no additions at year-end

Everything a London business actually needs
Core compliance, cloud bookkeeping, and proactive tax advice — all under one fixed monthly fee, with nothing buried in the small print.
Accounts, Tax and Compliance
Year-end accounts, corporation tax returns, Self Assessment, confirmation statements, and VAT — all filed on time and reviewed before submission. You will not be chasing us for an update, and nothing arrives at the last minute without warning. Your compliance obligations are mapped out and handled as a matter of course.
Included as standardCloud Bookkeeping and Payroll
Monthly bookkeeping on Xero or QuickBooks Online, with your records current and accessible whenever you need them. Payroll, RTI submissions, and CIS returns handled on schedule, with no manual chasing. Real-time figures mean your management accounts actually reflect what is happening in the business this month.
Remote and cloud-firstTax Planning and Business Advice
Knowing your tax liability in advance is not a luxury — it is how you plan properly. Alongside compliance, we cover capital gains tax, IR35 reviews, R&D tax credits, and director remuneration strategy. London business owners working through a limited company generally have more options than they realise; the job is making sure they are used.

What makes this different from most accountants
There are plenty of firms that will file your accounts. Fewer will tell you what they mean, flag what is coming, or price it clearly upfront.
Over 20 years of practice
Supreme Consulting has been working with small businesses and contractors since 2005. That is two decades of HMRC changes, tax regime shifts, and business cycles. The advice is grounded in what has actually happened to businesses like yours, not just what the textbook says.
Cloud-first from day one
Your books run on Xero or QuickBooks Online, with real-time figures accessible without emailing for a spreadsheet. Certified in both platforms, we handle the setup, migration, and ongoing reconciliation. You see your position when you want it, not six months after the fact.
Fixed fees, no moving targets
The scope is agreed upfront and priced clearly. There are no hourly rates ticking in the background, no unexpected invoice for a phone call. If your needs grow, you are told what the additional cost is before anything changes.
Up and running in four steps
Most clients go from initial call to fully onboarded within two weeks. The transition is handled at our end — you do not need to sort the admin before we can start.
A short discovery call
We spend 20 to 30 minutes understanding your business, your current setup, and what has been falling through the cracks. No obligation, no sales pitch. You will leave knowing whether we are the right fit before any proposal is sent.
A clear, fixed proposal
You receive a written proposal covering exactly what is included, the monthly fee, and the timeline. Everything is itemised — nothing is vague. If you have questions, they get answered the same day.
We handle the onboarding
We contact your previous accountant to retrieve the records, migrate your books to the cloud, and set up the integrations. Your job at this stage is minimal. If the books need catching up, we handle that as part of the transition.
Your finances, running properly
From here, your compliance is on schedule, your books are current, and your tax position is visible in advance. Regular check-ins, proactive updates when something relevant changes, and a direct line to someone who knows your business — which is, frankly, the way it should be.

Things London business owners usually ask
Do you actually work with London businesses, or is this just a location page?
We work with clients across the UK on a fully remote basis. London clients are a regular part of the practice — contractors, owner-managed limited companies, e-commerce sellers, and professional service businesses. Everything is handled via cloud accounting platforms and video calls, so location has not been a practical barrier since the firm was founded in 2005.
What does it cost, and what is actually included?
Pricing is fixed monthly, based on the scope agreed upfront. A typical limited company package covers year-end accounts, corporation tax (CT600), confirmation statement, and access to support through the year. Bookkeeping, payroll, VAT, and advisory services are priced separately and clearly. You receive a written proposal before anything starts — no hourly rates, no year-end surprises.
My books are behind and a bit of a mess. Is that a problem?
It is a common starting point. We handle catch-up bookkeeping as part of the onboarding process. The cost depends on how far back the records go and the volume of transactions, which we will be upfront about in the proposal. Most clients find that having everything sorted in one go is worth considerably more than the catch-up cost.
Am I locked into a contract?
There is no long-term lock-in. We work on a rolling monthly arrangement with reasonable notice on either side. If it is not the right fit, you leave with clean, up-to-date records transferred to your next accountant. We would rather you stayed because the service is worth it than because leaving is complicated.
I work through a limited company as a contractor. Does IR35 affect me?
Possibly, depending on your contracts and how your working arrangements are structured. We carry out IR35 reviews and can advise on whether your current contracts sit inside or outside the rules. For contractors in London’s professional and tech sectors in particular, it is worth reviewing your position rather than assuming everything is fine.
How far in advance will I know what my tax bill is?
For limited company directors, we aim to have your corporation tax liability estimated within a few weeks of your year-end, long before the payment deadline. For Self Assessment, you will know your personal tax position before the January filing rush. The point is to give you enough time to plan rather than simply react to a number when it arrives.
