Accountants for UK Tech, SaaS and AI Businesses

NDCA is an accountant for UK tech, SaaS and AI businesses. Tech, SaaS and AI founders rarely start a company because they love spreadsheets. They start because they built something worth scaling, then find out that R&D tax credits, EMI option schemes, SEIS/EIS investment rounds, deferred revenue and, for AI companies, compute costs and GPU capex all need handling correctly from day one. Get any of these wrong and you either overpay HMRC or fail due diligence when an investor opens the books. NDCA works with UK tech, SaaS and AI businesses to keep the numbers accurate and the structure clean, so you can focus on the product.

We make the numbers make sense. NDCA is an ACCA-regulated accountancy practice working with UK tech, SaaS and AI businesses, working primarily on Xero. We charge a fixed monthly fee, starting from £350/month, so your bookkeeping, VAT and year-end are managed every month, with numbers you can actually trust.

The tax issues that catch UK tech SaaS and AI businesses out

Most tech founders set up the company to build the product. But the way SaaS revenue is accounted for, the way R&D claims are prepared, the way share options are valued, and the way investors read management accounts, none of it is the same as normal trading. Get it wrong and it turns up at the worst possible time: in due diligence, in front of HMRC, or on a term sheet. We get it right from the start.

R&D tax relief claims that don’t hold up

Rules changed in April 2024. Most claims now go under the merged RDEC scheme (20% credit, ~15-16% net benefit). Loss-making SMEs can claim ERIS instead. Overseas R&D costs are mostly out. First-time claimants must notify HMRC within 6 months or the claim is gone. A well-prepared claim gets paid. A weak one gets challenged, delayed, or rejected.

SaaS revenue recognised incorrectly

A subscription paid annually upfront is not £1,200 of revenue on day one. It’s £100 per month, recognised over the contract term, with the unearned balance as deferred revenue. Most accountants get this wrong. The result is profit that swings wildly, management accounts that don’t match your MRR picture, and investor due diligence that uncovers a year of misstated income.

Share option compliance and tax planning

EMI options need strict compliance — HMRC valuation, grant notification within 92 days, annual returns. Get it wrong and you lose the tax advantages entirely. Founders taking low salary and most of their return through share value need to model the after-tax picture — salary level, dividend strategy, founder secondaries, buybacks — each has different tax treatment.

Investor-ready numbers that don’t exist yet

Cash burn, runway, MRR, ARR, deferred revenue, gross margin — investors will ask for all of it. Most accountants report only statutory accounts. You need monthly management accounts that show the metrics that matter, built cleanly from day one.

AI compute costs and R&D scrutiny

Compute is usually an AI company’s biggest cost line, billed in USD by OpenAI, Anthropic, AWS and Google Cloud, and it moves with usage rather than headcount. We track it separately from generic cloud hosting so gross margin per product stays visible, and we handle the FX. On R&D, HMRC has rejected a real volume of AI-related claims since 2023: prompt engineering and fine-tuning an off-the-shelf model rarely qualify, but genuine training-time experimentation and novel architecture usually do. We document the technical uncertainty as the work happens, not after the fact.

What can a tech or SaaS business claim as an allowable expense?

Allowable expenses for a tech or SaaS business cover most operating costs, provided they are wholly and exclusively for the trade. Common claims include:

Software, hosting and infrastructure

  • Cloud hosting and infrastructure (AWS, GCP, Azure, Vercel)
  • SaaS subscriptions used for the business (Slack, GitHub, Notion, analytics tools)
  • Domain names, SSL certificates and developer tooling licences
  • API and third-party data costs (Stripe, OpenAI, Twilio) used in running the product

Team and contractor costs

  • Salaries, employer NIC and pension contributions for employees
  • Payments to freelance developers and contractors (subject to IR35 checks for off-payroll workers)
  • Remote-working equipment provided to staff (laptops, monitors, home office kit)
  • Recruitment fees for hiring engineers and other staff

Office, travel and professional costs

  • Co-working space or office rent, utilities and business rates
  • Travel to investor meetings, conferences and client sites
  • Professional fees: accountancy, legal, company secretarial
  • Business insurance (professional indemnity, cyber, D&O)

Who we work with

NDCA tech, SaaS and AI clients fall into a few groups:

  • AI and ML businesses with significant compute costs
  • Venture-backed startups preparing for or post-fundraise
  • Bootstrapped SaaS businesses scaling from £10k to £100k+ MRR
  • Software agencies and development consultancies
  • Tech-enabled service businesses (marketing tech, ed-tech, fin-tech, health-tech)
  • Mobile app businesses with App Store and Google Play revenue
  • B2B software companies selling internationally
  • Founder-only limited companies for contracting developers

How NDCA works

Three things make our service different for tech, SaaS and AI businesses specifically.

Fixed monthly fee

You pay one price every month for everything we agreed at the start — bookkeeping, MRR and deferred revenue tracking, VAT, payroll, R&D claim support, year-end. No clock-watching, no per-question charges.

A real human, fast

You get a named accountant who understands SaaS metrics and tech business models. Most questions get a reply within one working day, which matters when an investor wants a clarification on the data room by 5pm.

Built around how a tech business actually grows

Tech businesses grow in steps — not in steady monthly increments. A new pricing tier, a Series A close, a contract that triples ARR overnight, a transatlantic hire. We build the workflow to handle the steps cleanly, not to be surprised by them.

Xero is the only platform we use

Xero is the only bookkeeping platform we run. For SaaS and tech businesses, that matters.

As an accountant for UK tech SaaS and AI businesses, we see Stripe and other subscription billing data feed into Xero through structured monthly journals — MRR, deferred revenue, refunds and chargebacks all coded correctly. Multi-currency invoicing for international customers is handled automatically. VAT is calculated and submitted directly to HMRC under MTD. Bank feeds reconcile against actual deposits. You see the same numbers every month — not whatever your billing dashboard happens to show on the day. If you are not yet on Xero, we migrate you across as part of onboarding. If you are already there, we plug straight in.

Apron for invoice capture

Tech and SaaS businesses still generate paperwork — AWS and cloud hosting invoices, GitHub and other dev-tool subscriptions, contractor invoices, app store and payment processor statements, software subscriptions spread across a dozen different cards.

We use Apron to capture all of it. Forward an invoice from AWS, GitHub, OpenAI or any other supplier to your dedicated Apron email address, or snap a photo, and the supplier, date, amount, VAT and line items are pulled out automatically and pushed into Xero — coded to the right cost line and matched to the bank transaction. By the time year-end arrives, every cost is documented and every allowable expense is claimed.

R&D claims and SaaS revenue recognition keeping you up at night?

Tech accounting has its own traps — software capitalisation, EMI scheme compliance, deferred revenue on annual contracts. Send us your situation and we will come back within one working day with a fixed monthly quote.

Switching from another accountant

If you already have an accountant and the reporting cannot keep up with your SaaS metrics, switching is simpler than people think. We send your current accountant a professional clearance letter, collect your records, and pick up where they left off. Most tech and SaaS clients are fully on-boarded within two weeks.

You do not need to wait for year-end. You do not need an awkward phone call. As your accountant for UK tech SaaS and AI businesses, we handle it.

Accountant for UK tech, SaaS & AI businesses: FAQs

Yes, but the rules changed for accounting periods beginning on or after 1 April 2024. Most companies now claim under the merged R&D Expenditure Credit (RDEC) scheme — a 20% credit giving roughly 15–16.2% net benefit. Loss-making SMEs with R&D spend of at least 30% of total expenditure can claim the more generous Enhanced R&D Intensive Support (ERIS) scheme. First-time claimants must notify HMRC within six months of the end of the period or the claim is gone.

A subscription paid annually upfront is not revenue when the cash is received. Under FRS 102 and IFRS 15, revenue is recognised over the contract term (typically monthly) with the unearned balance held as deferred revenue on the balance sheet. We set up deferred revenue schedules in Xero so MRR and recognised revenue stay accurate every month.

The Enterprise Management Incentive (EMI) is a tax-advantaged share option scheme for qualifying small companies. Employees can receive options worth up to £250,000 each, with no income tax or NIC on grant or exercise if the strike price equals market value. Capital Gains Tax applies on disposal at the Business Asset Disposal Relief rate of 18% (increased from 14% before 6 April 2026). EMI requires strict compliance — HMRC valuation, grant notification within 92 days, and annual returns. Get any of these wrong and you lose the tax advantages.

SEIS (Seed Enterprise Investment Scheme) gives investors 50% income tax relief on investments up to £200,000 per year in qualifying early-stage companies. EIS (Enterprise Investment Scheme) gives 30% relief on investments up to £1m per year in qualifying companies. Both have strict company qualification rules. We handle advance assurance applications and share issue compliance certificates.

Yes. Phone 01903 968618 or email info@nd-ca.co.uk.

You must register once taxable turnover exceeds £90,000 in any rolling 12-month period. Many tech startups register voluntarily before then to reclaim VAT on UK software, marketing and equipment costs — particularly worthwhile when you have significant pre-revenue spend.

Yes. NDCA is regulated by the ACCA (Association of Chartered Certified Accountants).

We are remote first. We work with tech businesses across the UK using Xero, so location does not matter.

Yes. AI startups have specific issues that do not fit the standard SaaS playbook — compute costs in USD, R&D claims under heavier HMRC scrutiny, Knowledge Intensive Company status for SEIS/EIS, EMI grants in a fast-moving valuation environment, and investor metrics that go beyond ARR. We build the workflow around these. We are not an AI-specialist firm — we are a tech-specialist firm with active AI clients, which means the rules are familiar and the support is consistent.

Yes. We prepare HMRC advance assurance applications for SEIS and EIS, advise on share structure and KIC qualification, run the compliance statements after share issue, manage the EMI option grant process (valuations, agreements, HMRC notifications), and maintain the cap table alongside Xero. For complex cap table situations (multi-class shares, growth shares, anti-dilution provisions), we coordinate with specialist equity counsel as needed.

Ready to hand over the spreadsheets?

Most tech and SaaS clients send us their billing exports once a month and never think about deferred revenue or year-end again. Send us a few details — we will come back within one working day with a fixed monthly quote.
