Affordable Accounting Software for Side Hustles: Options Under $20/Month

When I started my first side hustle three years ago, I tracked everything in a spreadsheet. It worked—sort of. But come tax time, I spent hours sorting through jumbled transactions, missing receipts, and confusing calculations. I knew there had to be a better way.

The good news? You don’t need to spend a fortune on accounting software for your side gig. Inc2025, there are numerous affordable options under $20 per month that can save you time, reduce stress, and potentially even help you identify tax deductions you might otherwise miss.

I’ve personally tested over a dozen accounting platforms while running various side hustles (freelance writing, e-commerce, and consulting). In this comprehensive guide, I’ll break down the best affordable accounting solutions, their key features, and which types of side hustles they’re best suited for.

Why Your Side Hustle Needs Proper Accounting Software

Before diving into specific platforms, let’s address why proper accounting software is worth the investment, even for a small side hustle:

1. Tax compliance: Accurately track income and expenses for tax reporting
2. Time savings: Automate repetitive tasks like receipt tracking and invoice creation
3. Profitability insights: See which activities actually make you money

According to a PCMag survey, small business owners and side hustlers save an average of 5 hours per month using dedicated accounting software instead of spreadsheets. That’s 60 hours per year you could spend growing your business or enjoying life!

Feature Comparison Chart

Here’s how these platforms stack up on key features important for side hustlers:

Best Accounting Software by Side Hustle Type

Different side hustles have different accounting needs. Here are my recommendations based on specific side hustle types:

For Freelance Writers, Designers, and Consultants

Best choice: FreshBooks or Wave

Freelancers need strong invoicing, time tracking, and client management. FreshBooks excels at these features, while Wave offers them for free with slightly fewer bells and whistles.

For Etsy Sellers and E-commerce Side Hustles

Best choice: Zoho Books

Online sellers need inventory tracking and sales tax management. Zoho Books offers these features at an affordable price point, with the ability to scale as your shop grows.

For Delivery Drivers (Uber, DoorDash, etc.)

Best choice: QuickBooks Solopreneur

Gig drivers need excellent mileage tracking and tax category suggestions. QuickBooks Solopreneur offers both, along with quarterly tax estimates to avoid surprises.

If you’re juggling multiple side hustles, Zoho Books offers the project tracking and categorization needed to keep different income streams organized.

Free vs. Paid: When to Upgrade

Many side hustlers start with free accounting software, but when should you consider upgrading to a paid plan? Here are some indicators:

Signs It’s Time to Upgrade:

1. You’re approaching transaction or client limits
2. Your side hustle revenue exceeds $1,000/month
3. You’re spending more than 2hours monthly on financial tasks
4. You need features like time tracking or mileage logging
5. Tax time was stressful last year
6. You’re considering scaling your side hustle

According to Homebase, the time savings from paid accounting features typically justify the cost once your side hustle generates consistent monthly income.

Setting Up Your Accounting System: Best Practices

Whichever platform you choose, follow these best practices to maximize its effectiveness:

1. Separate Business and Personal Finances

Even for a side hustle, maintain separate accounts for business transactions. This makes accounting significantly easier and protects you in case of tax audits.

2. Set Aside Time for Weekly Bookkeeping

Schedule 15-30 minutes weekly to categorize transactions, scan receipts, and review your financial position. Regular maintenance prevents end-of-year chaos.

3. Leverage Mobile Apps

All the software options listed offer mobile apps. Use them to scan receipts immediately and track expenses on the go rather than saving everything for later.

4. Create Templates for Recurring Tasks

Set up invoice templates, recurring billing, and standard expense categories to save time on repetitive tasks.

5. Connect Bank Accounts Securely

All modern accounting platforms use bank-level encryption. Connecting your accounts saves hours of manual data entry and reduces errors.

Tax Considerations for Side Hustlers

One of the biggest benefits of proper accounting software is simplified tax preparation. Here’s how to maximize this advantage:

Track Deductible Expenses

Common deductions for side hustles include:

• Home office expenses
• Business mileage
• Software subscriptions
• Professional development
• Supplies and materials
• Marketing costs

Set Aside Money for Taxes

Most accounting software can help estimate your tax liability. As a general rule, set aside 25-30% of your side hustle profits for taxes.

Generate Year-End Reports

Before tax season, generate these essential reports:

• Profit and Loss Statement
• Expense Summary by Category
• Sales Tax Collected (if applicable)
• 1099-NEC information (if you paid contractors)

According to TechnologyAdvice, side hustlers who use accounting software are significantly less likely to miss deductions than those using spreadsheets or manual methods.

The Hidden Costs of “Free” Accounting

While free accounting options like Wave’s core features are genuinely valuable, be aware of potential hidden costs:

Time Costs

Free options often require more manual work and offer fewer automations.

Transaction Fees

Many free platforms charge payment processing fees (typically 2.9-3.5% plus a fixed fee per transaction).

Upgrade Pressure

Free tiers may limit features until you hit friction points that encourage upgrading.

Limited Support

Free users typically receive limited customer support compared to paying customers.

That said, starting with a free option is often wise for new side hustles. You can always upgrade as your needs grow.

Making the Final Decision: How to Choose

With so many good options under $20/month, how do you make the final choice? Consider these factors:

1. Current Side Hustle Volume

If you’re just starting with a few transactions monthly, free options like Wave or Zoho Books’ free tier will likely suffice.

2. Growth Plans

If you plan to grow your side hustle significantly, choose software that can scale with you, like Zoho Books or FreshBooks.

3. Technical Comfort

If you’re not tech-savvy, prioritize user-friendly interfaces like ZipBooks or TrulySmall.

4. Tax Complexity

If your tax situation is complex, QuickBooks Solopreneur’s tax features may justify its slightly higher cost.

5. Try Before You Commit

Most options offer free trials or free tiers. Test drive your top choices before committing to a paid plan.

Conclusion: Investing in Your Side Hustle’s Financial Health

Even at just $15-20 per month, accounting software represents an investment in your side hustle. However, the time saved, stress reduced, and potential tax deductions identified make it one of the smartest investments you can make in your business.

For most side hustlers in 2025, Wave and Zoho Books offer the best combination of features and affordability. Wave’s completely free accounting features make it ideal for beginners, while Zoho Books provides a growth path as your side hustle expands.

Remember that the right accounting software doesn’t just track numbers—it gives you insights to make better business decisions, saves you time that you can reinvest in growth, and provides peace of mind knowing your financial records are organized and accurate.

Your side hustle might be “on the side,” but its financial management deserves proper attention. With today’s affordable accounting options, there’s no reason to struggle with spreadsheets or shoeboxes full of receipts.
