Online accountants for growing UK businesses
Why growing businesses outgrow flat-fee online accountants
Online accounting suits plenty of businesses. For a sole trader or a simple company, a flat fee for accounts and a tax return can be all you need.
Once you turn over £1m or more, the questions change. You are hiring, investing, borrowing or planning an exit, and you need current numbers, a forecast and someone who knows your business well enough to challenge your plans. A support queue and annual accounts do not do that.
At striveX you work with a named accountant who gets to know your business. You see monthly management accounts in plain English, a rolling cash-flow forecast and proactive tax planning, all delivered online, so it works wherever you are in the UK. If you would like to meet in person, we have offices in Manchester and High Wycombe, serving Oxford.
Built for owner-run businesses turning over £1m or more
Our clients are founders and directors running companies turning over in excess of £1m, including teams that are hiring and investing, and UK subsidiaries of overseas groups. If you are an overseas-owned business, see our UK subsidiary accountants.
We also specialise in technology and SaaS, manufacturing and construction and property businesses.

Monthly management accounts
Every month you get a clear pack in plain English: profit, margins, cash and how you are tracking against budget. We walk you through it on a video call, so you spot problems while there is still time to act.

Rolling cash-flow forecast
A forecast we keep up to date with you, so hiring, investment, VAT and tax bills are planned months ahead rather than discovered when the money is due. Useful for lenders, investors and your own peace of mind.

Tax planning all year
Corporation tax, director remuneration, R&D claims and reliefs are reviewed through the year, not after it has ended. You know what you owe and when, and your accountant tells you what could be done differently.

Accounts, VAT and payroll handled
Year-end accounts, corporation tax returns, VAT, payroll, CIS and Companies House filings prepared and filed online, to deadline, by a qualified team. Everything runs through cloud software you can see in real time.
Switching to an online accountant is simpler than most people expect. A named accountant guides you through it, and the handover usually takes around one week.

Intro call
Tell us about your business, your goals and what you need from an accountant. We come back with a clear proposal and a price.

Handover and set-up
We handle the handover from your current accountant and connect your cloud accounting, so nothing is done twice.

A monthly rhythm
Your books stay current and we review your numbers with you every month, with forecasts and tax planning so there are no surprises.

I’d like to give a special thank you to Molly Witty at StriveX, who supported me throughout my year-end accounting process. She has been incredibly helpful, patient and professional, always taking the time to explain everything clearly and answer my questions, no matter how small. She made the whole process feel much easier. I really appreciate her support and the personal approach she brings to her work. Thank you, Molly! I would highly recommend working with her.

I’ve recently onboarded my business with striveX and the whole experience has been excellent from start to finish. From my initial enquiry, everything has been handled promptly, professionally and, most importantly, in a really straightforward way. Jaya, Elysha and Tyarnna have all been first class throughout. They’ve been responsive, helpful and have made the whole onboarding process feel incredibly easy. One of the things I’ve particularly appreciated is how upfront and transparent everything is, especially when it comes to costs. There are no grey areas or surprises, and you know exactly where you stand from the outset. That was a big factor for me when choosing an accountant. It’s also refreshing to deal with a firm that feels modern and genuinely proactive, rather than simply being there to deal with the numbers at the end of the year. You get the impression they actually want to understand your business and help you move it forward. If you’re looking for a forward-thinking, proactive accountant who is easy to deal with and transparent about what they charge, I’d definitely recommend striveX. So far I couldn’t be happier with the decision to move across.

After a bad experience with my previous accountant I am so pleased I found Strive X! I used to dread anything to do with taxes and spreadsheets, but they have completely turned this around and I am now studying for my AAT Level 2 qualification. Not only are the team brilliant at what they do, they are also the most friendly, approachable and down to earth people who really care. A special shout out to Natasha the CIS queen for working so hard to sort out our CIS reclaims and to Amy for all her help with understanding tax planning. You are both amazing!

I’ve been incredibly impressed with StriveX - the attention to detail, proactive communication and ensuring I have all the information available to me to inform my decisions. The service experience is second to none. Thank you - particularly to Elysha, Amy-Leigh, Tyranna and Jack!

Truly informative and have helped me understand my own business much more. Molly and Elysha have been superb in their guidance, helping me navigate the business and increasing my level of understanding around tax and accounts. Wish I'd known about StriveX when I first started my company. I'm quite certain I'd be in an even better position now.

We've been really impressed with the service from Strive X. What stands out most is how organised they are and how clearly they communicate throughout the process. Everything is well planned, deadlines are clearly explained and we're always kept up to date, which makes dealing with our accounts with much less stress. The team is friendly, approachable and always happy to answer questions, no matter how big or small. A special mention to Amy, who led our recent tax planning meeting. She was incredibly helpful, explained everything in a way that was easy to understand and made sure we felt confident about the decisions we were making. Elysha is also really helpful and makes sure we are working together efficiently to suit the business and is very adaptive and supportive with that. It's reassuring to work with a team that is so professional, organised and easy to deal with. We'd happily recommend them to anyone looking for an accountant.

We've had such a positive experience since joining Strive. The whole team consistently goes above and beyond, but I wanted to give a special mention to Amy and Elysha. Amy recently led our tax planning meeting, and somehow managed to make a topic that can often feel overwhelming and serious both engaging and enjoyable. She put so much time, effort, and thought into the session, making it interactive, easy to understand, and dare I say, fun! I came away feeling confident in the decisions we were making, reassured that our accountants truly understand both us and our business, and grateful to have experts who genuinely care about our success. Elysha has also been fantastic throughout our time with Strive, always approachable, supportive, and happy to help whenever we've needed guidance. It's rare to find an accountancy team that combines expertise with such a personal, supportive approach. We genuinely appreciate everything Amy, Elysha, and the wider Strive team do for us, and feel incredibly lucky to have them supporting our business.
