Tracking expenses isn't just bookkeeping — it's how you maximize deductions, avoid tax surprises, and manage the 15.3% self-employment tax. We tested the top tools for freelancers and solopreneurs, from tax-first platforms like QuickBooks Solopreneur to free options like Wave.
If you're self-employed, every dollar you track is a dollar you can deduct. Miss a receipt, and you're leaving money on the table — money that's already been hit by the 15.3% self-employment tax. Expense tracking isn't busywork; it's the engine that powers your tax strategy.
We looked at the best tools for freelancers, solopreneurs, and independent contractors. Here's what we found.
| Tool | Best For | Schedule C Mapping | Quarterly Tax Estimates | Mileage Tracking | Price |
|---|---|---|---|---|---|
| QuickBooks Solopreneur | Tax optimization | ✅ | ✅ | ✅ | ~$15/mo |
| Wave | Budget-conscious / free | ✅ | ❌ | ❌ | Free |
| FreshBooks | Service-based freelancers | ✅ | ✅ | ✅ | ~$17/mo |
| Zoho Expense | Scalable / small teams | ✅ | ❌ | ✅ | ~$5/mo |
| Expensify | High-volume receipts | ✅ | ❌ | ✅ | ~$5/mo |
QuickBooks Solopreneur is built specifically for self-employed workers. It maps expenses directly to Schedule C line items and calculates quarterly estimated tax payments automatically.1 That alone can save you from underpayment penalties.
Why it wins for tax optimization: The platform categorizes expenses using IRS-friendly buckets — office supplies, vehicle expenses, insurance, retirement contributions — and generates a Schedule C draft at tax time. For anyone filing a Schedule C (which is most sole proprietors), this is the closest thing to a tax deduction engine on the market.
Trade-off: It's not free, and it doesn't include full double-entry accounting. But if your primary need is tax-ready expense tracking, this is the tool.

Wave is the best free accounting platform for self-employed workers who need basic expense tracking and invoicing without a monthly subscription.1
What you get for free: Unlimited expense tracking, bank account and credit card connections, receipt scanning via the mobile app, and professional invoicing. Wave makes money on payment processing fees (when clients pay invoices by card), not on your subscription.
Trade-off: No mileage tracking, no quarterly tax estimates, and limited reporting. It's great for getting started, but as your business grows, you may outgrow it.
FreshBooks is designed for freelancers who bill by the hour or by the project. It combines time tracking, invoicing, and expense management in one place.2
Why service pros love it: You track time against a client project, log expenses against the same project, and send an invoice that includes both — all from one interface. The mileage tracking is solid, and the mobile app makes it easy to snap receipts on the go.
Trade-off: It's pricier than the alternatives, and the expense categorization isn't as tax-focused as QuickBooks Solopreneur. But if you need time tracking + invoicing + expenses in one tool, FreshBooks is hard to beat.
Zoho Expense is an affordable option that scales from solo freelancers to small teams. It offers automatic expense reporting, receipt scanning with OCR, and mileage tracking.1
Why it stands out: The integration with Zoho's broader ecosystem (Books, CRM, Projects) means you can start with expense tracking and add more tools as your business grows — without switching platforms. The per-report approval workflow is useful if you eventually hire a contractor or assistant.
Trade-off: The free tier is limited (only 3 users, no mileage tracking on mobile). The paid plan starts at $5/month, which is still very reasonable.
Expensify's SmartScan feature extracts merchant, amount, date, and category from a photo of any receipt.1 For self-employed workers who deal with dozens of receipts a week, this is a game-changer.
How it works: Snap a receipt, Expensify reads it, categorizes it, and logs it. You can set up automatic rules — "any receipt from Staples goes to Office Supplies" — and the system learns your patterns over time.
Trade-off: Expensify is overkill if you have a low volume of expenses. The interface is also more corporate than the other tools here. But for receipt-heavy businesses (consultants, delivery drivers, tradespeople), it's the most efficient option.
Here's the math: the standard mileage rate for 2025 is 70 cents per mile. If you drive 5,000 miles for business, that's $3,500 in deductions. At a 22% tax bracket plus 15.3% SE tax, that's roughly $1,300 in tax savings — just from mileage.
Now multiply that across office supplies, software subscriptions, home office expenses, health insurance premiums, retirement contributions, and business meals. The total deduction potential for a typical freelancer is easily $10,000–$20,000 per year.2
The problem is that most people forget to log expenses in real time. By the end of the year, you're guessing. Automated expense tracking — connected to your bank accounts and credit cards — captures everything as it happens. You don't have to remember; the tool does.
That's the core insight: the best expense tracker isn't the one with the most features. It's the one you'll actually use consistently. Pick the tool that fits your workflow, connect your accounts, and let it run in the background.
