True-Cost Comparison: 3 Scenarios
Rankings change depending on your business type. Here are three common scenarios:
Scenario A: 1-person freelancer, 30 invoices/month, no payroll
| Option | Monthly cost | Winner? |
|---|---|---|
| Wave Free | $0 + processing | Best if no card payments |
| Zoho Books Free | $0 (under $50k/yr) | Best for under $50k/yr |
| FreshBooks Lite | $21 | Best invoicing UX |
| QBO Solopreneur | $20 | If you want QBO ecosystem |
Scenario B: 2-person LLC, 100 transactions/month, no payroll
| Option | Monthly cost | Notes |
|---|---|---|
| Zoho Books Standard | $15 | Best value for 2-person team |
| Xero Early | $25 | If you need unlimited users |
| FreshBooks Plus | $33 + $11 extra user | $44/mo total for 2 users |
| QBO Essentials | $75 | 3x the Zoho cost |
Scenario C: 5-person service business, payroll for 3 employees
| Option | Accounting | Payroll | Total |
|---|---|---|---|
| Xero Growing + Gusto | $55 | $49 + $18 (3ee) | $122 |
| QBO Plus + QBO Payroll | $115 | $50 + $18 (3ee) | $183 |
| Wave + Wave Payroll | $0 | $20 + $18 (3ee) | $38 |
Note: Wave lacks inventory and multi-user depth. For scenario C, Xero Growing + Gusto is the best-value complete solution.
When Cheap Costs You More
- Wave at high card volume: 2.9% plus $0.60 per transaction. At $50k/year card processing, the extra $0.30 vs Stripe adds $450/year - more than Zoho Books Standard.
- Xero Early with high invoice volume: The 20-invoice-per-month cap forces an upgrade to Growing ($55/month) mid-year. If you exceed it in month 3, you paid Early pricing for 3 months then pay Growing for 9 - you would have been better starting on Growing.
- Patriot with multi-state: Extra setup fees apply for multi-state payroll. Not cheap anymore.
- Any free tool when your accountant charges extra hours: If your CPA bills hourly and is not familiar with Zoho or Wave, the extra time at $150-300/hour outweighs the software savings fast.
