The Cheapest Way to Track Business Expenses as a Sole Trader

Sole traders and self-employed individuals often overpay for expense tracking software. Enterprise solutions are priced for businesses with employees. Consumer apps are built for personal budgeting. The overlap is thin.

The truth is you probably do not need to spend more than $5-6/month - and in many cases, nothing at all.

What you actually need

For a sole trader, the requirements are modest:

• Log expenses with category, amount, date, and a brief note
• Separate business and personal
• Export to CSV or PDF for your accountant
• Receipt attachment for high-value or unusual expenses

You do not need payroll, invoicing, P&L reports, inventory, or multi-user access. Those features drive the price up at most software products - and you pay for them whether you use them or not.

Free options that actually work

DrakeAI free tier - unlimited logging, text and voice input, CSV export. Works well for volume up to several thousand transactions per year. No bank connection required. Best for people who prefer manual logging with AI parsing.

Google Sheets - completely free, infinitely customizable. You enter expenses in a table. Formulas calculate totals. Filters separate business from personal. A template with the right columns is all you need. Not an "app" in the polished sense, but functional and zero cost.

Wave Accounting - free for basic invoicing and expense tracking. Aimed at small businesses but accessible for sole traders. Receipt scanning via mobile app. Decent tax report exports.

Expense tracking in plain notes - if your volume is low (under 50 business expenses per month), a simple note in Google Keep, Apple Notes, or Notion with a running list is sufficient. Copy it to your accountant at year end.

Paid options at reasonable prices

DrakeAI Pro - $5.99/month or $49.99/year. Adds unlimited Q&A queries and deeper analytics. Worth it if you want spending insights, not just records.

Expensify - from $5/user/month. More focused on expense reporting and reimbursement workflows than personal tracking. Better if you occasionally need to submit expenses to clients.

QuickBooks Self-Employed - around $15/month. Includes mileage tracking, estimated tax calculations, and Schedule C export. Worth the price if you have complex deductions. Overkill if you just need a log.

The tax-time test

Before committing to any solution, ask: "Can I get a CSV of all my business expenses for a date range?"

This is the minimum output needed for your accountant or for self-filing. If the answer is yes, the tool is sufficient. If the answer is no, find something else.

Most free tools pass this test. Most overpriced tools pass it too. The price difference usually comes down to automation (automatic bank sync, automatic mileage tracking) - which many sole traders do not need.

The real cost of complex software

The hidden cost of complex accounting software is time. Learning the software, maintaining it, fixing sync issues, reconciling errors. For a sole trader with straightforward expenses, this overhead often exceeds the time saved by the automation.

A simple tool you actually use beats a sophisticated tool you do not. Pick the simplest thing that covers your requirements, and invest the saved money and time in actual billable work.
