Still on the tools, but ready for more?

We’ll help you take the next step

We’re here to make your life easier

You’ve built a solid business, but one that is running you.

You went self-employed to earn a living, do what you’re good at, and have more control. But instead, you’re stressed about tax deadlines and trying to work out what you can claim.

Behind the scenes, things are probably a little messy too.

You might have:

Be constantly playing catch-up with paperwork
Be earning cash but have no system to track it
Be stressed every time your tax return is due
Not be sure what you can claim (or what’s coming up next)
Be thinking about going limited, hiring, or stepping back from the tools
Feel stuck doing everything yourself, with no time to actually grow

Sound Familiar?

If so, you’re not alone. You know your trade inside out, but you need someone who can sort the finances.

Our packages for Sole Traders

You may have heard about HMRC’s new rules ‘MTD ITSA’ for sole traders and property landlords on how their report on their income, which start in April 2026. To make this change completely stress-free, we are already getting all our sole trader clients set up and compliant now. It means you’ll be ready long before the deadline, with no last-minute rush or worries.

Let’s be straight with you. We know you could pay less just to get your tax return filed, and for some people, that’s enough. But what you’re paying for is a once-a-year transaction, not year-round support. With a basic filing service, there’s no one keeping an eye on things for you, no one to call with a quick question in August, no-one to help you with a mortgage certificate and no help getting organised for the year ahead. Our packages are designed to give you that continuous support and peace of mind.
