Accountants and bookkeeping for UK startups, from formation and tax to runway, SEIS, R&D and investor reporting. Fixed-fee online support.
Short answer
Startup accountants should build clean records from the first transaction, keep tax and Companies House filings on schedule and produce numbers founders can use. As the company grows, support can extend to runway, revenue recognition, fundraising, SEIS or EIS, R&D and investor reporting.

From accountant to finance function
Startup accountants should build clean records from the first transaction, keep tax and Companies House filings on schedule and produce numbers founders can use. As the company grows, support can extend to runway, revenue recognition, fundraising, SEIS or EIS, R&D and investor reporting.
Set up the bank, bookkeeping, expense policy, payroll and share records correctly before volume grows. A simple chart of accounts and monthly close create a reliable base for tax, board reporting and due diligence.
Startup bookkeeping should separate product development, cloud infrastructure, contractors, sales and funding transactions. Subscription businesses also need billing data reconciled to cash and deferred revenue, not just a bank feed.
SEIS and EIS, EMI options and R&D relief each have detailed conditions and sequencing risks. Advance assurance, share issues and technical claims should be reviewed before commitments are made, with statutory registers and cap tables kept consistent.
Founders need current cash, burn, runway, gross margin and hiring commitments. Management accounts should reconcile to the ledger and explain performance against plan rather than report vanity metrics alone.
Early startups may need only compliance and bookkeeping. Funded teams can add a controller, monthly reporting, forecasts and fractional CFO support without hiring a complete internal department immediately.
Rates, thresholds and deadlines quoted here reflect the current UK position and current HMRC and Companies House guidance. Check GOV.UK, or ask us, before relying on them for your own business.

“Accotax have been our accountants for many years now. We maintained them because of their professionalism. In the last couple of years I have been working with Imran, who has been very professional and helpful in guiding us through the whole process, explaining and clarifying every aspect of it. Very prompt in responding to questions and patient with us even when we seem to be slow.”
“We worked with a few different accountants before finally settling with Accotax, and we're really glad we did. They take the time to understand how our business works and what our needs are. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing, professional, efficient, and follows the processes we have put in place together. Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.”
“I've been working with Accotax since January 2024, and their support has grown alongside my business needs. My personal allocated manager, Umer, provides tailored services for both of my companies, adapting as I expand and ensuring everything runs smoothly. They are responsive, knowledgeable, and always clear in their communication. Their help with accounts, VAT, payrolls, pensions and compliance gives me real confidence and peace of mind.”
