What Our Clients Say
Client Testimonials
I've spoken to a handful of accountants and have decided to go with SBX, if I'm being honest, the other accountancy firms struggle with getting back to me within a reasonable time. But these guys really are what they say! available at all times for any financial advice and set ups guidance.
The team at SBX have really made sorting my CIS returns and Self Assessment so much easier. I used to stress about deadlines and whether I was paying too much tax, but they’ve really taken the pressure off. They know their stuff and have saved me both time and money - would definitely recommend them.
SBX Accountants made managing my year-end filings completely hassle-free. Their team are really professional and knowledgeable, I had no idea I could claim certain expenses until they walked me through it, helping me save significantly more tax than in previous years! Highly recommend their services.
