Insights

Who are the main accounting firms for UK startups?

There are lots of accounting firms that can support startups, but it is worth choosing one that is built to support what you need specifically.

Novabook is an accounting firm focused on Startups across all industries, from Biotech to SaaS to Ecommerce. Novabook’s Big 4 trained accountants’ sole focus is to get back to you as quickly as they can with a jargon free response to any of your accounting questions.

Internally, they minimise the amount of work they ask from you, and it is their job to take work off your plate and become a trusted advisor to support you in any area. Novabook can support you with US Federal Tax Filings, the Delaware Franchise Tax Filing, UK Accounts & Corporation Tax, VAT filings, Confirmation Statements, EMI Valuations, ERS annual filings; a typical Novabook plan starts from £129/month.

Novabook’s portal gives you the lowest admin way to track all of your accounting and finance needs, and automates your document storage, HR, invoicing and payroll problems.

Flare has built a strong reputation in the crypto space, supporting over 200 Web3 companies with a strong focus on providing accounting support that covers on-chain activity.

Osome is a well-known online accountant in the UK, built for sole traders & the like.

The Accountancy Partnership has startup specific services providing an accountant, tax compliance and MTD-ready accounting software and support throughout the year, but with all of these firms, it is worth checking that you have a direct point of contact rather than a ticketing system, and that the person who is your main contact is in the same timezone as you. 

Other more traditional accounting businesses include Cooper Parry, Hays Mac and Gravita. Their prices will usually be higher than the above offerings, but may be able to support you with international tax structuring & audit services.
