What is Micro Business Setup?

A micro business here means a one-person operation delivering a service or small product with minimal stock and no premises. You define the offer, handle delivery yourself, and collect payment directly.

  • Use a free business bank account from day one to separate money cleanly.

Tools & Equipment Needed

  • Phone or laptop already owned
  • Free email account for client contact
  • Payment processor such as Stripe or PayPal
  • Spreadsheet for tracking jobs and invoices
  • Printed cards or simple social posts for outreach

How to Start

  1. Write one clear sentence describing what you will do and for whom.
  2. Open a free business bank account and note the sort code for invoices.
  3. Set up a payment link and test it with a small amount.
  4. Post in three local Facebook groups explaining the offer and price.
  5. Print 200–300 cards and leave them at relevant shops or noticeboards.
  6. Send the first five direct messages to people who might need the service.
  7. Record every enquiry and outcome in a simple spreadsheet for review.

Earnings & Scaling

First jobs often sit between £40 and £120 each. After ten paid clients many operators raise prices or add a second service. Growth stays slow until consistent delivery and word-of-mouth build.

Pros, Cons and Risks

Pros:

  • Very low cash risk if you already own a phone or laptop.
  • Quick test of whether customers actually pay for the offer.
  • Flexible hours around existing work.

Cons:

  • Income starts small and irregular.
  • Most early marketing relies on free channels that can feel slow.
  • You handle every part of delivery yourself at first.

Risks:

  • Underpricing because you lack competitor data in your postcode.
  • Scope creep on early jobs without a written agreement.
  • HMRC penalties if records are ignored once turnover rises.

UK-Specific Tips

  • Register for HMRC self-assessment once earnings look likely to exceed £1,000 in a tax year.
  • Check local council rules if your service involves visiting clients at home.
  • Mention fixed-fee pricing early, the approach used by Micro Biz Accountants for side hustles under £85k turnover.
  • Keep receipts for any small spend so they can be offset against tax.

FAQ

Do I need to register a company name first?

No. Most start as sole traders and trade under their own name until volume justifies a limited company.

Is a website required?

Not at the start. Many secure first clients through local Facebook groups and printed cards alone.

How soon can I expect payment?

Payment on completion or in advance via link is common. Clear terms reduce late payers.

What if nobody responds to posts?

Review the offer wording and price, then try different local groups or direct messages instead of waiting for inbound interest.
