For millions of UK taxpayers, filing a Self-Assessment Tax Return is a yearly ritual — one that combines deadlines, spreadsheets, and HMRC forms. Yet every year, tens of thousands of people make costly errors that trigger penalties, repayments, or unwanted investigations.

When you’re running a small business, managing your finances efficiently can feel like a juggling act. You need to track income, expenses, taxes, and cash flow—all while trying to grow your customer base. One of the most practical ways to simplify this process is through cash-based bookkeeping.
