Sound familiar?
Still doing your own books between sprint planning?
Early-stage founders typically end up as the de facto finance function — reconciling bank feeds late on a Sunday, guessing at the tax bill, and realising too late that a confirmation statement was due. The books are always slightly behind. The runway figure in your head and the one in the accounts rarely match. Investors ask for management accounts and you are not entirely sure what to send them.
- No real-time view of runway or burn rate between funding rounds
- Statutory deadlines missed or flagged late — Corp Tax, confirmation statements, payroll
- No management reporting or KPI pack to put in front of investors or the board
What a sorted finance function looks like
Cloud accounting means your books are current and your numbers are visible without you touching a spreadsheet. Every statutory obligation is tracked and filed. When an investor asks for management accounts, they are already prepared.
- Runway and burn rate tracked monthly on cloud platforms — no guesswork between rounds
- All Companies House and HMRC filings handled on schedule under the ACSP regime
- Monthly management accounts with KPI dashboards ready for investors or board review
- Fixed monthly fee — no surprise invoices when a filing lands or a question gets asked
What London tech founders say about working with us
Startups and growing tech businesses across London — from pre-revenue setups to investor-backed companies — on what changed when the finance function was handled properly.
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 startup needs from its accounts
Compliance handled, management reporting built, and FD-level input available when the business reaches the stage where it needs it — all on cloud platforms.
Management Accounts and KPI Reporting
Monthly management accounts built around the metrics that matter for a tech business — MRR, burn rate, gross margin, runway. Delivered in a format that works for internal teams, investors and lenders. No reformatting required when someone asks for the numbers.
Cloud-delivered monthlyStatutory Compliance, Fully Handled
Corporation Tax, VAT, payroll, confirmation statements and annual accounts — all filed on time, directly by the firm under the ACSP regime. Deadlines are tracked centrally so nothing relies on a calendar reminder in a founder's inbox.
ACSP authorisedVirtual Finance Director for Growth Stages
When the next funding round, an acquisition conversation or a board hire requires proper strategic finance input, a virtual FD engagement provides that without a full-time hire. Founder Niall O'Driscoll FCMA, CGMA brings 10-plus years of restructure and turnaround work, including listed companies, to engagements that warrant it.
Available on engagementConsistent across years and client types
Verified Google reviews going back more than a decade — sole traders, startups, established SMEs and non-standard clients all describing the same experience.
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 More Than Cover the Fees
“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.”
Brilliant With a Tricky Non-Standard Client
“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…”
Why London tech founders choose a cloud-first chartered firm
There is no shortage of accountants in London. The difference is whether they understand how a tech business actually runs — and whether they bring anything beyond compliance.
Built on cloud platforms, not paper
The firm is cloud-first by design — Xero and best-of-breed SaaS integrations are not bolt-ons, they are the operating model. That means your books are current in real time, KPI dashboards pull live data, and nothing waits for a quarterly catch-up call to get updated. A tech startup gets the same standard of management information as a business three times its size.
FD-level input without the full-time hire
The virtual finance director service brings chartered management accounting and commercial finance experience into the business on an outsourced basis. Founder Niall O'Driscoll FCMA, CGMA spent over a decade on freelance restructure and turnaround work, including listed companies — that depth of experience is available to a London tech startup at a fraction of the cost of an in-house FD hire.
All Companies House filings in-house
OD Accountants is an Authorised Corporate Service Provider under the Companies House regime — confirmation statements, statutory submissions and annual accounts are all handled directly by the firm. There is no reliance on a third-party agent and no additional step for the client. Obligations are tracked centrally and filed on time.
Up and running in four straightforward steps
The onboarding process is designed to require as little from you as possible. Most clients are set up and running within a week or two of the initial call.
Book a discovery call
A short call — usually thirty minutes — to understand where the business is, what is currently in place, and what needs to change. No preparation required on your side. You will leave the call knowing exactly what is proposed and what it will cost.
Receive a fixed-fee proposal
A clear written proposal covering what is included, what the monthly fee is, and how the engagement works. No ambiguity about what falls inside or outside the scope. If the proposal works for you, onboarding begins immediately.
We handle the migration and setup
If your books are on a legacy platform or in reasonable disarray, the team handles the migration into the cloud stack. Access to existing accounts, HMRC authorisations and any catch-up work are all coordinated by the firm — not delegated back to you.
Finance function running, founder focus restored
Once the engagement is live, the compliance obligations are tracked and handled, the management accounts arrive monthly, and questions get answered the day they are asked. The finance function is no longer something that requires founder attention every week.
“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!!”
What tech startup founders usually ask us first
Do you understand SaaS metrics, cap tables and equity structures — or will I need to explain the business model from scratch?
No explanation needed from scratch. The firm works with tech startups, SaaS businesses and founder-led companies regularly — MRR, ARR, churn, burn rate and runway are standard reporting outputs, not things that require a briefing document. Equity structures, share option schemes and the Companies House implications of each are part of the day-to-day work.
What does it cost and what is included in the monthly fee?
Fees are fixed and agreed upfront — no variable billing when a filing lands or a question gets asked outside of a scheduled call. The fee is scoped to the engagement, so a pre-revenue startup pays differently to a Series A company with payroll and management reporting requirements. Clients in the Google reviews consistently describe the pricing as competitive and the savings as more than covering the cost. The quickest route to a figure is the free quote form on this page.
Our books are a mess from the last eighteen months. Can you still take us on?
Yes, and this is not unusual. Most new clients arrive with books in some state of disarray — incomplete reconciliations, transactions sitting uncategorised, or records split across two or three platforms. The team handles the catch-up as part of onboarding. Catch-up work is scoped and costed separately so you know what it involves before committing.
Is there a minimum contract term or a penalty for leaving?
No long-term contract and no exit penalty. The engagement runs month to month once onboarding is complete. If it is not working after a reasonable period, you leave with clean books, all data exported in a portable format, and nothing owed beyond the current month. The aim is to keep clients because the service is worth keeping, not because leaving is inconvenient.
Can you support us through a funding round or investor due diligence process?
Yes. Management accounts, KPI packs and financial models for investor presentations are standard deliverables for clients at that stage. The virtual FD service can be engaged for more intensive support — financial modelling, scenario analysis and lender or investor reporting — where the funding round requires it. Founder Niall O'Driscoll's background includes commercial finance and restructure work across listed companies, so the due diligence environment is not unfamiliar territory.
When will I actually know what my Corporation Tax bill is going to be?
The intention is that the tax position is visible well in advance of the filing deadline — not something that arrives as a surprise number in a letter from HMRC. Management accounts are prepared monthly and the tax computation is built as part of the year-end process, so the figure is known and planned for before payment falls due. R&D tax credit eligibility is also assessed as part of the year-end review where the business qualifies.
