Fixed fee accounting, delivered online
We combine two things that make accounting simpler: a price that doesn't change, and an accountant you can work with from anywhere in the UK.
What is a fixed fee accountant?
A fixed fee accountant agrees one price for your accounting and tax work before anything starts, usually paid monthly. You aren't charged by the hour, so your bill doesn't grow when you call, email or ask a question covered by your package.
- Know exactly what you'll pay every month
- Budget with confidence and spread the cost
- Ask questions without watching the clock
What is an online accountant?
An online accountant provides the same services as a high street firm — accounts, tax returns, VAT, payroll and advice — but works with you by phone, email and video, using cloud accounting software. You share records digitally and get expert help wherever you are.
- No office visits or paper to post
- Real-time figures in cloud software
- Support across England, Scotland, Wales and Northern Ireland
How it works
Moving to a fixed fee online accountant takes a few days, not weeks.

Frequently Asked Questions
What does “fixed fee accountant” mean?
As a fixed fee accountant, we charge a set price for our services rather than billing by the hour. You know exactly how much you'll pay up front, with no surprise costs later. Your fee covers an agreed set of services for a set period, usually monthly, so you can ask questions and seek advice without being charged for every conversation.
How much do your accountancy services cost?
Your price depends on your business type, turnover, number of transactions and the services you need. You can choose a pre-built package, build your own package, or pay a one-off price for a single job. Request a free quote and we'll confirm your fixed fee before any work starts.
Are there any hidden costs?
No. Your fixed fee is agreed before we start and covers everything listed in your package. If you ever need work that isn't included, we'll tell you the price and agree it with you first.
What does an online accountant do?
An online accountant provides the same services as a high street firm, including accounts, tax returns, VAT, payroll and advice, but works with you by phone, email, video call and cloud accounting software. You share records digitally, so you can use an expert accountant wherever you are in the UK.
Can I switch accountants part way through the year?
Yes. You can switch at any time. We contact your current accountant for the information we need, take over your HMRC and Companies House authorisations, and make sure your deadlines are covered.
Are you HMRC registered agents?
