You narrowed free invoicing to two names, Wave and Zoho Invoice, and now you are stuck between them. Fair: both are free, both are good, and they are good at opposite things. Wave is the all-in-one: invoicing plus bookkeeping in one dashboard. Zoho Invoice is the specialist: deeper invoicing automation with time tracking and expense tracking built in. If you have not read the broad field first, start with our free invoice generator guide, then come back, this page settles the final two.
Below: where each wins on features, the true cost as you grow, and a decision rule that takes ninety seconds.
The one-paragraph difference
Wave answers “how is my business doing”, invoices, payments, and accounting reports in one free account, with no client or invoice caps. Zoho Invoice answers “how do I bill this project precisely”, hourly timers, retainers, and per-project expenses that flow onto the invoice automatically, free for one user up to 1,000 invoices a year. Bookkeeper-brain picks Wave; project-brain picks Zoho. Everything below is just evidence for that sentence.
Features that matter at solo scale
Both cover the basics: unlimited professional invoice templates, recurring invoices, automatic payment reminders, client portals, and multi-currency support. The split starts at the edges. Wave includes full double-entry bookkeeping, bank connections, and payroll add-ons (US, paid), it wants to be your finance department. Zoho includes project timers, retainer tracking, and workflow automation (late-fee rules, custom functions), it wants to be your billing department. Neither includes inventory management worth mentioning, which is fine: freelancers sell hours, not boxes.
Payment gateways differ most. Wave locks you into Wave Payments (2.9% + $0.60 card, 1% ACH in the US). Zoho lets you plug in Stripe, PayPal, Square, or regional gateways and keep negotiated rates. If you already process through Stripe for other income, Zoho avoids a second payout pipeline and a second 1099-K source to reconcile.

True cost as you grow
| Stage | Wave cost | Zoho Invoice cost |
|---|---|---|
| Solo, 10 clients | $0 | $0 |
| Solo + card payments ($3k/mo) | ~$90/mo processing | ~$87/mo processing (Stripe) |
| Add a VA/bookkeeper (2nd user) | $0 (add accountant free) | ~$20/mo (paid plan) |
| Need payroll (US) | Wave Payroll from $19/mo | Via Zoho Payroll/Books (separate) |
| Outgrow trigger | Leaving North America | Needing full accounting suite |
Processing fees dominate both columns, and both lose to ACH transfers (~1%) wherever clients agree. The structural difference: Wave monetizes processing and add-ons while the core stays free forever; Zoho monetizes seats, so the second human costs money. Solo-plus-bookkeeper setups are actually cheaper on Wave.
Migration risk: what if you pick wrong?
Low both directions. Both export clients, invoices, and payments to CSV, and neither holds your data hostage. A Wave-to-Zoho move costs an afternoon of mapping chart of accounts if you used Wave’s bookkeeping, the one thing Zoho cannot import cleanly, since Zoho Invoice is not a ledger (pair it with Zoho Books or a spreadsheet instead). Zoho-to-Wave is simpler: clients and open invoices transfer, history stays as PDFs. Wrong picks here cost hours, not months.
The 90-second decision
Do you want your books done where you invoice? → Wave. Do you bill hours, hold retainers, or already use Stripe? → Zoho Invoice. Outside the US or Canada? → Zoho (Wave is North-America-centric). Still torn? Run both free for one billing cycle with two real clients each, at $0 the experiment is free, and one of them will feel like home by the second invoice. Our broader invoice generator comparison covers the PayPal backup play if neither fits.
