I have just started as a sole trader
You are trading in your own name, income has started arriving and nothing is organised yet.
Founder & writer — writes from experience
As a sole trader you and the business are the same legal person, so every pound that arrives is partly yours, partly HMRC's and partly the cost of doing the next job.
You do not need software, an accountant or a system diagram in week one. You need a separate account, a tax percentage and a weekly ten-minute habit.
What to fix first
- 1
Separate the money
Open an account used only for business income and business costs, and stop paying for groceries from it.
- 2
Reserve tax from day one
Move a fixed percentage of every receipt into a pot you never touch.
- 3
Invoice properly and immediately
Same-day invoicing with clear terms is the cheapest cash-flow improvement available.
Your seven-day plan
Day 1
Separate every receipt
Choose one account for business income and costs, then list any payments that still leave through your personal account.
Day 2
Create an invoice template
Add your trading details, a clear description, payment terms and a reference number before the next job is complete.
Day 3
Choose a reserve habit
Move a percentage of each paid invoice to a clearly named tax reserve and record the transfer.
Day 4
Capture proof
Photograph or file the receipts, supplier invoices and payment confirmations from this week.
Day 5
List recurring costs
Write down software, insurance, travel, materials and subscriptions so the next payment is not a surprise.
Day 6
Check unpaid invoices
Confirm who owes you, when each payment is due and what you will do if a due date passes.
Day 7
Run a ten-minute review
Compare money received, money spent, tax moved and cash left; repeat the same review every week.
Numbers and documents to collect
- Business-income record
- It gives every receipt a date, customer and payment reference.
- Expense evidence
- Keep the supplier document and payment proof together.
- Invoice template
- It keeps payment terms and numbering consistent from the start.
Irregular first month
A new sole trader receives £900 for a project, moves a chosen reserve amount, pays £120 for materials and keeps the remainder in the business account until the next weekly review.
The point is not to calculate a final tax bill from one payment. It is to avoid treating the full £900 as personal spending money before costs and tax are understood.
Common mistakes and red flags
- You cannot tell which recent card payments were business costs.
- You are spending from money set aside for tax.
- You are doing work without a clear written payment request.

When this path is not the right one
- If you handle a lot of physical cash, check deposit fees and branch access before choosing an app-based account.
- A business credit card is not appropriate at this stage — most providers require a limited company, and new sole traders rarely need credit.
