Startups Have Unique Needs.
Generic Advice Won't Cut It.

We are accounting specialists for business startups — one of eight specialist sectors we serve at MazeKey. Startups face a completely different set of challenges compared to established businesses: unfamiliar legislation, uncertain cashflow, rapid structure decisions, and the need to build solid financial foundations under pressure.

We’ve been working with businesses across the UK from inception through to growth for over 20 years. We understand what new businesses need — not just compliance, but the strategic and practical financial support that gives you the best possible chance of success.

“Contractors can save money by registering as Limited Companies. Pharmacies can be more tax-efficient in the way they do business. The same principle applies to startups — the right structure and advice from day one makes all the difference.”

If you are thinking of starting a business in London or anywhere across the UK, contact us today. We work with startups across every sector — from technology and retail to professional services and creative industries.

Six Areas Where Startups,
Need Specialist Support

Generic accounting services aren’t designed for the startup environment. Here’s where specialist knowledge makes a measurable difference to your business from the very start.

Fast, accurate setup

Get registered and trading correctly from day one

Tax-efficient from the start

Structure your business to save tax legally and immediately

A long-term partner

We grow with your business as you scale

Choosing the Right Structure

Sole trader, partnership, or limited company? The wrong choice costs you money from day one. We assess your situation — income level, growth plans, liability exposure — and advise the most tax-efficient structure for your specific circumstances.

Business Plan & Financial Projections

A credible business plan with realistic financial forecasts is essential for funding, investor conversations, and your own direction. We help you build projections that are grounded in reality and commercially credible.

Funding & Finance Access

From government startup loans and SEIS/EIS investor schemes to R&D tax credits and bank funding — we identify every source of finance available to your business and help you access it with properly prepared financials.

Cloud Accounting Setup

Setting up Xero, QuickBooks or Sage correctly from the very start prevents years of messy records. We configure your system, connect bank feeds, set up invoicing templates and train you or your team to use it effectively.

Legal & Tax Compliance

From Companies House registration and HMRC enrolment to VAT registration and PAYE setup — we ensure every compliance obligation is met correctly from the outset, so you never face an unexpected penalty or investigation.

Cashflow Management

Cashflow is the single biggest reason startups fail. We build cashflow models for your business, monitor them regularly, and help you plan for growth — ensuring you always know exactly where your cash position stands.

Everything a New Business Needs Under One Roof

We provide everything a startup needs from its accountants — from initial registration and structure advice right through to year-end accounts, corporation tax and beyond. No hidden extras, no jargon, no long-term contracts you don’t need.

Company Formation & Registration

We handle your Companies House incorporation, HMRC registration for corporation tax, PAYE and VAT — ensuring your business is correctly set up from the very first day of trading.

Bookkeeping & Cloud Accounting

Clean, accurate bookkeeping using Xero, QuickBooks or Sage — set up correctly from day one so your records are always organised, accessible and ready for any filing deadline.

Tax Planning & Corporation Tax

We structure your startup tax-efficiently from the outset — covering corporation tax, self-assessment for directors, dividend planning and identifying every allowance and relief available.

VAT Registration & Quarterly Returns

We advise exactly when and how to register for VAT, select the right VAT scheme for your business model, and handle all quarterly MTD-compliant submissions accurately and on time.

Payroll & Auto-Enrolment

From your first hire onwards, we manage payroll, RTI submissions to HMRC, workplace pension auto-enrolment and all associated compliance — so your team gets paid correctly every time.

R&D Tax Credits & SEIS/EIS

If your startup is innovating or seeking investment, we identify R&D tax credit claims and advise on SEIS/EIS eligibility — potentially recovering significant cash to fund your next stage of growth.

How We Launch Your Business Right

From your very first call through to ongoing support as your startup grows — here’s exactly what working with MazeKey looks like.

Formation & Setup

We handle company formation, all HMRC registrations, and configure your cloud accounting system — so you can start trading with everything properly in place.

First Year Support

Quarterly bookkeeping, VAT returns, payroll, management accounts and tax planning throughout your first trading year — with expert guidance at every stage.

Growth & Beyond

Year-end accounts, corporation tax, funding applications, new hires, expansion planning — we scale our support as your business grows and evolves.

Starting Up Is Exciting.
The Admin? Not So Much.

Start-up businesses are some of the most vulnerable when it comes to longevity. Within five years, the majority won’t survive — due to cashflow difficulties, lack of proper planning, the wrong business structure, and compliance issues that could have been avoided with the right advice.

We understand the differences between industries and — in particular — what is required from us as your business advisers. We’ve been working with businesses across the UK from startups to contractors to public sector organisations, providing specialist accounting advice that genuinely makes a difference.

Having the right accountancy support from day one puts your startup in a far stronger position — freeing you to focus on building your business while we handle the financial and compliance foundations that keep everything on track.

Contact us today and find out how we can help you beat the statistics and build a successful, sustainable business from the ground up.

Starting Up Without a Specialist

Records in disarray — expensive clean-up required at year-end
No strategic guidance — every decision made without financial insight
