Accountants for Tech Startups London
Finance sorted while you build the actual product.
Most London tech founders are running their finance function on instinct and a shared Google Sheet. That works until it does not — and it usually stops working around the time a funder asks for management accounts. OD Accountants is a cloud-first chartered management accounting firm: fixed monthly fees, FCMA-qualified, and questions answered the day you ask them.
- Management accounts and KPI dashboards ready when investors ask
- Cash-flow runway visible every month, not just at year-end
- Corporation Tax planned in advance — no surprise bills in April
- Companies House filings handled directly under the ACSP regime
No long-term contract. If it is not working after three months, you leave with clean books and nothing owed.

Building a startup and doing the books yourself?
Most early-stage London tech founders are the de-facto finance director, head of operations and product lead simultaneously. The accounting is usually the last thing looked at and the first thing that causes a problem — a missed VAT threshold, management accounts that do not exist when a funder asks for them, or a Corporation Tax bill that lands without warning. None of these are disasters, but they all cost time and money that a startup cannot spare.
- No management accounts when an investor or bank asks for them
- VAT threshold approaching with no plan in place
- No visibility of cash runway until the bank balance forces the conversation
What a properly sorted finance function looks like
The compliance gets filed on time and correctly. The management information exists and is current. You know your tax position before HMRC writes to you. The finance function runs in the background while you focus on the product.
- Monthly management accounts and KPI dashboard — ready before anyone asks
- VAT threshold monitored — you will not miss a registration obligation
- Cash-flow forecasting updated monthly so runway is always visible
- Fixed monthly fee — no hourly surprises, no year-end invoice shock
What startup founders say about working with OD
From pre-revenue founders setting up their first limited company to funded startups needing investor-grade reporting — a consistent picture across the reviews.
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.
The finance function your startup actually needs
From day-to-day bookkeeping and payroll through to investor-ready management accounts and virtual FD support — built on cloud accounting software and delivered at a fixed monthly fee.
Management Accounts and KPI Reporting
Monthly or quarterly management accounts with KPI dashboards — historical performance, forward forecasts and variance analysis. Formatted for management teams, funders and lenders, so they are ready when someone asks rather than built in a hurry after they do.
Included for growing startupsVirtual Finance Director Support
For startups that want strategic finance input without a full-time FD salary, OD acts as an outsourced finance director. Cash-flow modelling, funding-round preparation, scenario planning and commercial finance advice — the kind of support that is usually only available to businesses large enough to hire one in-house.
Available as an add-onCorporation Tax, VAT and Compliance
Corporation Tax planned and filed on time, VAT returns managed under Making Tax Digital, and Companies House filings handled directly under the ACSP regime. The compliance obligations are met without the founder needing to track deadlines or decipher HMRC correspondence.
Included as standardConsistently the same picture across the reviews
Clients across start-ups, consultancies, retail and hospitality — many of them multi-year clients — describe the same things: responsive, hands-on, and worth considerably more than the fee.
Years of Service, Always Above and Beyond
“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 Cover the Fees Many Times Over
“Unlike my previous Accountants, Niall is far more hands-on, available for advice and able to care for me as an individual, rather than a faceless client. His fees are very reasonable and the money he has saved me more than covers them.”
Handled a Tricky Non-Standard Setup Confidently
“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…”
What makes this firm a good fit for London tech startups
Not every accounting firm is built around the way a startup's finance function actually needs to work. These are the specific reasons OD tends to suit the sector.
Built on cloud accounting from day one
The firm runs on Xero and best-of-breed SaaS integrations — the same stack a modern startup is likely already using or moving towards. There is no persuading anyone to adopt new technology: the workflow, KPI reporting and forecasting are built for how fast-moving businesses actually operate. Real-time data rather than a once-a-year catch-up.
FD-level thinking without the FD salary
Founder Niall O'Driscoll FCMA, CGMA spent over a decade doing freelance restructure and turnaround work across listed UK and overseas companies before founding OD Accountants. That depth of commercial finance experience is available to startups that could not ordinarily justify a full-time finance director. Strategic input on funding rounds, cash modelling and commercial decisions — not just compliance filing.
Responsive to the way startups actually work
Verified Google reviews consistently describe the team as 'always available', 'fast to respond' and willing to 'go above and beyond'. For a founder whose questions do not keep office hours, that matters more than a firm with a formal ticketing system and a 72-hour response SLA. Questions get answered the day they are asked.
Up and running in four straightforward steps
The onboarding is designed to be low-effort on your side. Most founders are live within a week of the discovery call.
Book a discovery call
A 30-minute call to understand where the business is, what the finance function currently looks like and what you need from an accountant. No preparation required. You will leave knowing exactly what happens next and what the monthly fee would be.
Receive a fixed-fee proposal
A clear scope of work and a fixed monthly fee — no hourly rates, no surprise invoices. If the books are in some state of disarray, that is accounted for in the proposal rather than discovered halfway through onboarding.
We handle the migration
OD manages the transfer of your accounting data into the cloud platform, connects the integrations and sets up the reporting structure. The administrative lift is almost entirely on the OD side, not yours.
Run the business, not the books
From month one, management accounts are produced on schedule, compliance deadlines are handled and your tax position is visible well in advance of when it matters. The finance function runs in the background. You focus on the product.
“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 first
Do you understand how SaaS and tech startups structure their finances — MRR, ARR, deferred revenue, R&D relief?
Yes. These come up regularly with startup clients. Deferred revenue treatment, recognising subscription income correctly, R&D tax credit claims and the metrics that matter for SaaS reporting — MRR, ARR, churn, CAC — are all part of the work rather than something you need to explain from scratch. The management accounts are structured around how your business actually measures performance, not a generic limited-company template.
What does it cost and what is included in the monthly fee?
Fees are fixed and agreed upfront — no hourly rates and no invoices arriving after work has already been done. The exact figure depends on the scope: bookkeeping, payroll, VAT, management accounts, virtual FD support and Corporation Tax can each be included or excluded. Clients in the Google reviews describe the pricing as 'very reasonable' and 'competitive', with tax savings that more than cover the engagement. The free-quote form or discovery call is the quickest way to get a specific number for your setup.
Our books are a mess — transactions in the wrong categories, months behind. Is that a problem?
It is common, not a problem. Catch-up work is scoped and priced as part of the initial proposal so there are no surprises partway through onboarding. The data migration and historical clean-up are handled by OD, not handed back to the founder. Most clients arrive with books in some state of disarray and leave with considerably less to worry about.
Is there a minimum contract or a lock-in period?
No long-term contract. Engagements run on a rolling monthly basis. If it is not working, you leave with clean books, all your data exported and nothing outstanding. The aim is to make leaving genuinely easy — which is, frankly, a reasonable incentive to do the job well.
We are planning a funding round. Can OD help with investor-ready reporting and financial modelling?
Yes. Producing management accounts and financial models for investors and lenders is a core part of what the firm does. Founder Niall O'Driscoll has a background in restructures and commercial finance across listed companies, so funding-round preparation — including cash-flow forecasting, scenario modelling and lender-pack formatting — is well within scope rather than a specialist add-on. The virtual FD service is specifically designed for this kind of engagement.
When will I actually know what my Corporation Tax bill is going to be?
Well in advance of the deadline, not when the payment is already due. The tax position is visible throughout the year via the management accounts and updated as the numbers change. There should be no moment where a Corporation Tax bill is a surprise — which is generally the point at which it becomes the most expensive version of the problem.
