How to Write a Professional Business Bio

The four-sentence structure

Almost every strong short bio follows the same shape:

• Sentence one: what you do and who for
• Sentence two: proof — experience, specialism, or qualification
• Sentence three: how you work, or what makes the experience different
• Sentence four: where you work and how to start

Write the plain version first

Before you polish anything, write it plainly: "I clean holiday rentals in Brighton. I have done it for six years and I work with eleven hosts. I do same-day turnovers and send photos after every clean. Message me for availability."

That version is already better than most published bios because it is specific. Polishing means improving the rhythm, not removing the facts.

Choose one tone and hold it

Professional: measured, credential-led, suitable for consultants and advisors. Warm: conversational and personal, suitable for care, hospitality, and home services. Premium: restrained and confident, suitable for photography, design, and high-value services.

Mixing tones is what makes a bio read as generic. Pick the one that matches the experience the customer actually gets.

Common mistakes

• Opening with "We are a passionate team dedicated to excellence" — it describes nobody
• Listing every service instead of the main one
• Writing in the third person when you are a one-person business
• Leaving out location when your customers are local
• Never updating it after your services change

Keep three versions

Keep a 40-word version for directories, a 100-word version for your website, and a 250-word version for proposals and press. Write the long one, then cut it down twice. Editing an existing bio is far faster than writing a new one for each place it appears.
