How to Track Income and Expenses as a Sole Trader
Quick answer
Track sole trader income and expenses by recording business payments in, business payments out, and the receipt or invoice behind each entry.
A spreadsheet can work when you are small. A bookkeeping app can be easier once you have regular transactions, invoices, bank feeds, or receipts to manage.
What income should you track?
Track all money your business receives.
This might include:
- client payments
- cash sales
- marketplace or platform income
- online shop payments
- tips or commission
- other self-employed business income
Record the date, amount, source, and what the payment relates to. If you invoice clients, include the invoice number too.
What expenses should you track?
Track business costs separately from personal spending.
Common sole trader expense records include:
- software and subscriptions
- tools and equipment
- business travel
- office costs
- phone and internet costs
- marketing costs
- accountant or professional fees
- bank fees and payment processing charges

The simple tracking method
Use one place for income and one place for expenses.
For each income entry, record:
| Date | Source | Description | Amount | Paid into |
|---|---|---|---|---|
| 12/06/2026 | ABC Ltd | Invoice 001 | £450 | Business account |
For each expense entry, record:
| Date | Supplier | Description | Category | Amount | Receipt |
|---|---|---|---|---|---|
| 14/06/2026 | Adobe | Design software | Office costs | £54.99 | Digital |
Keep the receipt, invoice, or confirmation somewhere you can find it later.
Spreadsheet vs app for sole traders
Spreadsheet
A spreadsheet is usually enough if:
- you have only a few transactions each month
- you do not send many invoices
- you are comfortable entering figures manually
- you want the lowest-cost option
Start with the bookkeeping spreadsheet template if you want a simple structure.
Bookkeeping app
A bookkeeping app may be better if:
- you want bank transactions imported automatically
- you send invoices
- you want receipt capture
- you want clearer reports
- you keep forgetting to update a spreadsheet
Some business bank accounts include bookkeeping features or software connections. See best free business bank accounts for sole traders if you are choosing banking at the same time.
Use a separate bank account if you can
A separate business account is not legally required for UK sole traders, but it can make tracking much cleaner.
When business money is separate, your bookkeeping starts with a cleaner bank feed. You are not trying to separate client payments from supermarket shops, rent, subscriptions, and other personal transactions.

Weekly routine
Do this once a week:
- Check your bank account
- Add new income
- Add new expenses
- Attach or save receipts
- Make a note for anything unclear
- Check unpaid invoices
Do this once a month:
- Compare your tracker to your bank statement
- Fix missing or duplicated entries
- Review expense categories
- Back up your records
When to move from spreadsheet to software
Move to software when the spreadsheet starts creating more work than it saves.
Common signs include:
- you regularly miss transactions
- you spend too long matching receipts
- clients ask for proper invoices
- you want automatic bank feeds
- you want a clearer view of profit
- you are preparing for future digital reporting requirements

Final recommendation
Start with the system you will actually keep up with. For many beginners, that means a separate account, a simple spreadsheet, and a weekly routine.
If your business becomes regular, a bookkeeping app can save time and reduce manual errors.
