Eight disciplines,
one continuous brief.
We don’t sell hours. We hold a continuous brief over the numbers — quietly compounding small adjustments into substantial savings, and intervening before HMRC ever needs to. Every fee is fixed at the outset and quoted in pounds, not hours. Every engagement is led by a qualified accountant.

The unglamorous
work, done
properly.
The mark of a good accountant isn’t speed. It’s the absence of unpleasant surprises in March.
One name on every engagement
Your first call, your final review — the same qualified accountant. No mystery handover, no shifting team.
Year-round counsel, not year-end panic
We forecast tax quarterly. You make decisions before they become liabilities, not after.
Plain English, never jargon
Every letter we send to HMRC, we explain to you in two short paragraphs first. No surprises.
Fixed fees, agreed up front
Set at the outset, reviewed annually. We do not bill in six-minute increments.
“ We thought the SA100 was just paperwork. Sowilo treats it as a year-round planning conversation — pension carry-forward, marriage allowance, dividend timing. The savings aren’t dramatic; they’re consistent. ”
Sole-trader consultant · Bristol
A frank conversation,
personally led.
A candid talk with a qualified accountant about where you are, what’s overdue, and whether Sowilo is the right practice for the work. No salesperson, no follow-up chase. If we aren’t the right fit, we’ll say so and point you to someone who is.
