I am calling this the "Mistake post".

Wait. Did I post this by mistake?....

No, I promise. This is a bookkeeping post about the mistakes that quietly cost business owners money. There are many, so I will take one mistake at a time. This post is only about Mistake 1.

Mistake 1: Mixing personal and business spending One coffee here, one grocery bill there, and by the end of the month nobody knows whose money was spent. Yes, that coffee was a "business meeting". With yourself.

It looks small. It is not. Here is what it quietly does to your business:

Your profit becomes wrong. Personal costs sit inside business expenses, so the numbers do not show how the business is really performing.

Your bank reconciliation becomes slow. Every personal payment needs an explanation before your books can match the bank statement.

Your tax work becomes harder. When costs are mixed, it is difficult to prove which expenses truly belong to the business.

You lose clarity. You cannot tell how much the business earned and how much you took out for yourself.

Check your statement once a week. Small habit. Clean books. Much less stress at year end.

Mistake 2 is coming in the next post, so follow along so you do not miss it.

Project title: Board Report Redesign: Q3 Performance Pack (Power BI) Same financial data, redesigned from a plain Word report into a one-page Power BI board view. The problem Board and management reports are often full of accurate numbers that nobody reads closely. Tables, long paragraphs and default charts make people hunt for the headline.

What I did To show my approach, I built a fictional company’s Q3 board report two ways from the same Excel workbook: a typical plain Word version, and a redesigned one-page Power BI view.

What I changed • Key figures (revenue, profit, closing cash, variance to budget) placed first • A waterfall that takes cash from opening balance to closing cash • Clear chart titles, with units where they apply • One colour system applied across every visual • All figures tie back to a single workbook, with DAX measures checked against it

Deliverables in this sample • Plain “before” report (Word, 8 pages) • Redesigned Power BI board view (PDF) • Source workbook structure and a custom navy and gold theme

Note: The company, figures and report are fictional, created only to demonstrate my approach. No real client data is used.

What I can do for you I design board packs, investor decks and monthly management reports for SMEs and finance teams, in Power BI and Excel. If your reports get skimmed instead of read, message me.
