Three accounting tools, three approaches to the same problem: tracking what you make and owe. After a full tax year on each, here is where they actually differ.

Most independent service providers don't need a CPA — they need a system that makes the CPA's job easy and cuts their tax-season stress in half. Three tools do the bulk of this work for sole proprietors: QuickBooks Self-Employed, Wave, and FreshBooks.
After running each on a real book of business for a full tax year, here is where they differ.
Wave is free for accounting and invoicing. Payments and payroll cost extra — standard 2.9% + 60¢ for card processing. QuickBooks Self-Employed runs $20/month and bundles mileage, receipt capture, and quarterly estimated-tax nudges. FreshBooks starts at $21/month for five clients and scales up from there.
If you're under $60K gross and do under 30 invoices a year, Wave is very hard to beat on cost.
FreshBooks wins this category and it isn't close. The invoice builder is the cleanest, late-fee automation actually works, and clients can pay in two clicks. QuickBooks' invoices are fine. Wave's feel like they were designed in 2019 (because they were — Wave's product investment has slowed noticeably since the H&R Block acquisition).
If invoicing is the center of your work — consulting, coaching, retainer clients — FreshBooks is worth the $21.
QuickBooks Self-Employed wins this category for one specific reason: it's the only tool of the three that estimates your federal quarterly tax payments in real time based on categorized transactions. It also exports directly into TurboTax Self-Employed, which if you file yourself saves about two hours.
Wave does categorization well but leaves the math to you. FreshBooks' tax tools have improved but still feel bolted on.
Only QuickBooks has native mileage tracking (via the mobile app, auto-detected). For anyone driving to client sites — trainers, stylists, photographers, cleaners — this alone can justify the $20/month.
Wave and FreshBooks both require a third-party app like MileIQ (~$6/month) to capture mileage usefully.
All three connect to major US banks. Stripe and Square feed cleanly into QuickBooks and FreshBooks; Wave treats them as separate accounts that need manual reconciliation for the invoicing side.
None of the three replaces a CPA if you incorporate, hire staff, or cross six figures in revenue. All three get you cleanly through Schedule C.
