Accountants for Tech Startups London
Your startup's finances, handled properly.
Most London tech startups reach a point where a spreadsheet and a basic bookkeeper are no longer enough. You need management accounts, a cap table that makes sense to investors, and someone who can read a burn rate without needing it explained. OD Accountants is a cloud-first chartered management accounting firm: fixed fees, FCMA-qualified, and questions answered the same day.
- Monthly management accounts and KPI dashboards ready when you need them
- Corporation tax planned in advance — no surprise bills in January
- Your cloud accounting stack configured and running correctly from day one
- Virtual FD support available when investor conversations or funding rounds arrive
No long-term contract. If it is not working after three months, you leave with clean books and nothing owed.

Sound familiar?
Good product. Chaotic books.
Most London tech startups are building something serious while running their finances on the back of a very thin setup. The bookkeeping is behind, the management accounts have never existed, and corporation tax is something to worry about later. Later arrives faster than expected. The problem is not that founders are careless — it is that they have been given accounting support designed for a corner shop rather than a company that needs to raise, report and grow.
- No management accounts, so investor questions land without a clean answer ready
- Cloud accounting set up incorrectly — figures that cannot be trusted
- Corporation tax and R&D relief treated as afterthoughts rather than planned in advance
What the finance function should look like
A chartered management accounting firm that already understands how tech businesses are structured. Monthly accounts, KPI reporting, correct cloud setup, and strategic finance input — all on a fixed fee, without hiring internally.
- Monthly management accounts and a KPI dashboard ready before any investor asks
- Your Xero or cloud platform configured correctly — figures you can rely on
- Corporation tax and any applicable reliefs planned well before the year-end deadline
- Fixed monthly fee — no hourly billing, no surprises at year end
What London startups say about working with us
From first-time founders to growing tech companies, the consistent feedback is responsiveness, accuracy, and support that goes further than compliance.
As a new start up and having never dealt with an accountant, Niall at OD Accountants has been very welcoming and supportive. All our prior queries and issues have been resolved, and he is always available to meet the needs of our team.
The service from OD has been excellent, as has their advice. It's great to have access to a financial team who can guide us with such confidence and seamlessly integrate with our internal team. We always feel well-informed and confident about our financial processes and data. Highly recommend.
Everything a growing tech company needs
Three core areas of support, delivered on a fixed monthly fee through cloud-first workflows — from day-to-day compliance through to strategic finance and fundraising-ready reporting.
Compliance and Clean Books
Bookkeeping, payroll, VAT returns, corporation tax and statutory accounts — handled monthly through Xero or your existing cloud platform. Your records are current, your filings are on time, and your figures can be trusted when someone external looks at them. No year-end scramble.
Included as standardManagement Accounts and KPI Reporting
Monthly management accounts with a KPI dashboard built around the metrics that matter to your business — burn rate, gross margin, MRR, or whatever your model requires. Available for management review, lender reporting or investor conversations as needed. Historical and forward-looking views, not just a rear-mirror snapshot.
Advisory tierVirtual Finance Director Support
For startups that want FD-level input without a full-time hire, OD Accountants can act as an outsourced finance director — cash-flow forecasting, scenario modelling, funding support and commercial finance advice drawn from over a decade of restructure and turnaround work across listed and private companies. The kind of support that is normally available only to businesses large enough to hire one internally.
vFD engagementClients across a decade and counting
Verified Google reviews going back over eleven years, from first-time founders to established SMEs — a reasonable range of businesses, consistently saying the same things about responsiveness and value.
Years With Them, Always Available
“I've been there for years and Niall and his team go above and beyond the duties to provide accounting services but also general advices. They are always available if you need anything while charging very competitive prices. I could not recommend them enough.”
Savings More Than Cover the Fees
“His fees are very reasonable and the money he has saved me more than covers them. If you need an Accountant who cares, Niall and OD Chartered Management Accountants are the way to go.”
Brilliant Help Despite Tricky Client Status
“Been with OD Accountants for over a year now. Niall and the team are brilliant. They helped me set up a company and get everything I needed in place to run my business. I'm a tricky client due to my 'digital nomad' status, but their advice…”
Built for tech businesses, not retrofitted for them
Three reasons why the firm works well for London tech startups in particular — not generic accountancy firm claims, but specifics that are either true or they are not.
Cloud-first from the ground up
The firm is built around modern accounting software and best-of-breed SaaS integrations — not a traditional practice that has bolted on a Xero licence. That means your management information is live, your app stack is correctly configured, and the reporting is built for how tech businesses actually run. No chasing PDFs by email.
Strategic finance without a full-time FD
Founder Niall O'Driscoll FCMA, CGMA spent over a decade as a freelance accountant specialising in restructures and turnarounds, including listed companies in the UK and overseas. That depth of commercial finance experience is available to startups that want strategic input — cash-flow modelling, funding-round support, scenario planning — without the cost of a full-time hire.
Responsive, not transactional
Verified Google client reviews going back more than eleven years consistently describe the team as always available and willing to go above and beyond. For a startup where a question about SEIS eligibility or a director's loan account can surface at an inconvenient moment, that matters. Questions get answered the day they are asked.
Up and running in four straightforward steps
The onboarding process is designed to minimise disruption. Most clients are fully set up within a few days of the first call, with catch-up work handled by the firm.
Book a discovery call
A 30-minute call to understand your business, your current setup, and what you actually need. No obligation, no sales script. You will leave knowing exactly what the engagement would look like and what it would cost.
Receive a fixed-fee proposal
A clear proposal setting out the scope and a fixed monthly fee. No hourly rates, no unexpected invoices mid-year. If your books need catching up, that is costed separately and transparently upfront.
We handle the transition
Switching from another accountant or starting from scratch — the firm manages the data migration, HMRC authorisations, and cloud platform configuration. You do not need to manage the handover yourself.
Accounts running, head clear
From month one, your books are current, your management accounts arrive on schedule, and your tax position is visible rather than something to worry about at year end. The finance function runs in the background while you build the business.
“Niall and his team are supportive, clear and directional accountants who have supported our small business staff up. They're always on the end of the phone to advise and assist and provide a top service for our accounting needs. Plus they're just nice people which helps too!!”
Things London tech founders usually ask
Do you understand how tech startups and SaaS businesses are actually structured — ARR, MRR, burn rate, cap tables?
Yes. The management reporting OD Accountants produces is built around the metrics that are relevant to the specific business model — which for a SaaS company means recurring revenue, churn, gross margin on software delivery, and cash runway, not a generic profit and loss designed for a retailer. You will not need to explain what MRR means before getting a useful answer.
What does it cost, and what is included in the fee?
Fees are fixed monthly and scoped to what your business actually needs — bookkeeping, payroll and compliance sit at one tier; management accounts and KPI reporting at the next; virtual FD engagements are agreed separately. Clients consistently describe pricing as very reasonable and competitive, with savings on tax and avoided penalties typically more than covering the cost. A specific figure is provided in the proposal after the discovery call, once the scope is clear.
My books are behind and my Xero is a mess. Is that a problem?
No. Catch-up work is a normal part of onboarding for many clients. The firm will assess the state of the records during the discovery call and cost any catch-up work transparently before you commit. Data migration from other platforms, or from a manually maintained spreadsheet, is handled by the firm — not handed back to you as a task.
Is there a minimum contract or lock-in period?
No long-term contract. The engagement runs on a rolling monthly basis. If it is not working, you give notice and leave with your books in better order than you arrived. The firm's preference is for long-term client relationships — verified reviews going back over a decade reflect that — but that is earned, not contractually enforced.
Can you help with SEIS / EIS compliance and R&D tax credit claims?
Yes. SEIS and EIS advance assurance applications, investor documentation and the associated compliance sit within the scope of what OD Accountants handles. R&D tax credit claims require a thorough understanding of the qualifying activity, and that conversation is worth having early in the year — not the week before the CT600 is due. Both are areas where the planning matters as much as the filing.
When will I know what my corporation tax bill is going to be?
With monthly management accounts and a year-to-date view of the tax position, you will have a reliable estimate of the corporation tax liability well before the year end — typically with several months to plan around it. The aim is that the final bill confirms what you already expected, rather than arriving as news.
Stop guessing what your finances look like. Get it sorted.
A discovery call takes 30 minutes. You will leave with a clear picture of what the engagement covers, what it costs, and what changes from month one. No obligation.
