Why expense tracking matters
for your business

Every pound your business spends is a record worth keeping. Whether it is software subscriptions, travel costs, professional fees, or office rent — logging expenses consistently gives you a clear picture of your true profitability and keeps your finances ready for Self Assessment.

UK sole traders and small business owners spend an average of two days every January scrambling to piece together a year of expenses before the Self Assessment deadline. BFSB eliminates that entirely. Log expenses as they happen, assign them to a category, and the tax year grouping and HMRC mapping happens automatically.

When you are ready to file or meet your accountant, download a clean Excel export for any tax year, categorised, totalled, and ready to hand over. No formatting, no chasing bank statements, no last-minute panic. Just clean records that took seconds to maintain throughout the year.

Built for UK Self Assessment

Ready for Self Assessment before January arrives

BFSB groups your expenses by UK tax year and maps them to HMRC allowable expense categories automatically. When January comes, you will not be hunting through bank statements. You will have a clean, categorised export ready to send to your accountant.

  • Rent → HMRC: Office & property costs
  • Travel & Transport → HMRC: Car, van and travel expenses
  • Professional Services → HMRC: Legal and financial costs
  • Software & Subscriptions → HMRC: Allowable subscriptions
  • Salaries → HMRC: Staff expenses

HMRC category mapping is shown as a reference guide. Always confirm deductibility with your accountant.
