Plain-English guides, tools and checklists for UK business owners

Business finance made simple for UK founders and small business owners

Understand your business money before it controls your business.

Run the numbers without becoming an accountant.

You started the business to do the work, not to forecast cash or reserve for tax. This site explains the money side in plain English, one decision at a time, with the sources shown and the limits stated.

General information, not regulated financial, tax or legal advice. Some links are affiliate links and are always labelled. How we make money.

The person behind every guide here — a business owner who learned this the hard way, not a regulated adviser.

Meet Daniel
  • Lived experience meets professional verification. Daniel writes every guide from his direct experience, which is then peer-reviewed by qualified accountants and business advisers for technical accuracy. Our expert review policy
  • Commercial content is labelled and dated. Partner offers show the last verified date and disappear automatically when a campaign lapses.
  • Sources are cited. Tax, invoicing and company rules link to GOV.UK, HMRC and Companies House rather than to us.
  • Credit is never pushed at people in trouble. Distress signals suppress every credit module sitewide.
