Efficient, polite, helpful!
Nicole was recommended to me by a friend, and helped me with my self-assessment over several years; I was self-employed with a part-time PAYE job and she made everything so much easier. She was always on-hand via email or phone/zoom call if needed, and responded quickly. I would absolutely recommend her to anyone self-employed or running a small business.

Threeboxes Accounting: Saves you pennies and worry! Highly recommend
Nicole has done an amazing job with my accounts, making it a seamless and stress free experience start to finish. Being both newly self-employed (2 businesses may I add) and employed, I was at a loss of how to do my first tax return.
Nicole put me at ease, with her friendly manner, professionalism and knowledge, making the daunting prospect much more manageable.
And thanks to Nicole's expertise, I've got a nice tax rebate coming my way!
Look no further if you're in a similar situation to me or fully self-employed. Nicole will save you pennies, and worry.
Very happy customer and will be using Three Boxes Accounting moving forward.

I am a new freelancer and was a bit…
I am a new freelancer and was a bit daunted with submitting my first tax return. It wasn't going to be that straightforward as had been employed for a period and recieved benefits too. But Nicole helped me understand what was needed, handled the submission to HMRC and ensured that I got it all done quickly after the year end so I could see how much I would need to pay. Thanks Nicole. Would recommend!

I read a positive review on social media about Three Boxes and decided to give them a ring. They were absolutely fantastic. Personable, professional and efficient.

I was worried about not having worked…
I was worried about not having worked because of the COVID-19 pandemic, how I would present my Business Tax Return, but Threeboxes took care of it all.

Perfect for start ups!
As a start up, it’s sometimes hard finding people you can trust; who knows what they’re doing and are competitively priced. It’s been a wonderful and easygoing experience working with Threeboxes. I let them get on with it and focused on other parts of my business. I’ve already recommended them to everyone I know as they’re fantastic, and I hope you use them too!
