Sole Traders
Full Ownership. Full Control. Full Potential.
A sole trader (also called a sole proprietorship) is the simplest and most common business structure in the UK. It involves one individual running a business on their own, where the owner and the business are legally the same entity. You work for yourself, make all decisions, keep all profits after tax, and bear full personal responsibility for debts and liabilities.

CBM Accounting supports sole traders with tax, bookkeeping, payroll, and compliance. We help keep finances organised, tax-efficient, and fully compliant, so you can focus on growing your business.
