How much does a startup accountant cost?
Accounting and tax for a limited company starts at £49 a month + VAT. The fee is set by your turnover, so the instant quote works out your figure and emails the full proposal, and the price is confirmed in writing before you commit. Payroll is charged on top of the monthly fee: £8 per employee a month, or £12 if you pay weekly or fortnightly, with a £25 monthly minimum and a £75 set-up fee. Business Pulse, forecasts and specialist work such as an R&D claim or SEIS advance assurance have their own prices on our pricing page.
Who do you work with?
UK startups that plan to grow: software and SaaS companies, e-commerce and direct-to-consumer brands, fintech, deep tech, biotech and AI companies, and founders getting ready to raise money. The accounting and tax work is the same for all of them, and each sector has its own page on where R&D relief, VAT and cashflow differ.
Can you set up my limited company?
Yes. We handle the incorporation, a share structure that is ready for investors, and registration for corporation tax, VAT and PAYE where each applies, and we set up Xero so the books are organised from the first transaction.
What software do you use?
Xero and Buzz OS. Buzz is a Xero Gold Partner, and we set Xero up around how your business makes money. Xero is paid to Xero, and its UK plans start at £18 a month + VAT. Buzz OS is the platform Buzz built to run your accounts with you, and it is included in your fee.
Can you help us raise money?
We get you ready and help you work out what kind of money fits. That means knowing your cash position, a forecast with its assumptions written down, books and filings a lender or investor can check, and SEIS or EIS if you are selling shares to individual investors. This work is priced separately from your monthly fee.
We haven't incorporated yet. Is it too early to talk?
No. A conversation before you incorporate lets us set up the share structure, VAT position and payroll correctly from the start.
