Wave vs Nudge Billing: Which Free Invoicing Tool Is Better?
Wave is the most established free invoicing tool. Nudge is newer and built around a different problem. Both are free. They're not really competing for the same freelancer.
Here's an honest breakdown.
What Wave Does Well
Wave has been around since 2010 and has earned its reputation. The free plan is genuinely free with no invoice limits. You get invoicing, client management, and a real accounting system that tracks income, expenses, and generates financial reports.
If you want to run your entire freelance finances inside one tool — invoices, expense tracking, P&L reports — Wave can do that without charging you anything for the accounting features. That's a real differentiator.
Wave also has a decent mobile app, recurring invoices, and an established track record. A lot of freelancers have been using it for years and have no reason to switch.
Wave's limitations:
Payment processing is where Wave makes money. They charge 2.9% + $0.60 for credit cards and 1% for bank payments. That's market rate, but you're locked into Wave's payment system. If a client wants to pay via Venmo or Zelle, they can't do it through a Wave invoice. You'd have to collect separately and record it manually.
There's also no automated follow-up for unpaid invoices. Wave will show you which invoices are overdue, but the follow-up is on you to manage.
What Nudge Does Well
Nudge is built for one specific problem: getting paid faster. It does that through two features Wave doesn't have.
The first is multi-payment support. A Nudge invoice shows all your payment methods on one page: Stripe for cards, PayPal, Venmo, Zelle, bank transfer. The client picks what works for them and pays in one click. No friction, no "how do I pay you?" emails.
The second is automated reminders. Invoice sent. If the client doesn't pay by the due date, Nudge sends reminders at day 3, 7, and 14 automatically. You don't write the emails or track the due dates. It just runs.
The free plan covers 5 invoices per month. Pro is $9/month for unlimited invoices, plus features like logo branding, custom email templates, sequential invoice numbering, and CSV export.
Nudge's limitations:
No built-in accounting. Nudge is not going to replace a bookkeeping tool. If you need expense tracking, profit and loss reports, or tax prep support, you'll need a separate tool for that.
The free plan is limited to 5 invoices per month, which is fine for part-time freelancers but not enough for anyone with a high invoice volume.
How to Decide
Choose Wave if: You want accounting and invoicing in one place, you send more than 5 invoices per month and don't want to pay anything, or your clients all pay by card and bank transfer.
Choose Nudge if: Your clients use different payment apps and you're tired of the friction, you want automated follow-up reminders without managing them yourself, or you're focused on reducing days-to-payment rather than tracking expenses.
The core difference is what problem you're solving. Wave solves the "I need to track my finances" problem. Nudge solves the "I need to get paid faster" problem.
Most freelancers who switch to Nudge aren't replacing Wave entirely. They're using Nudge for invoicing and keeping Wave (or a spreadsheet) for expense tracking. You can run both.
If getting paid faster is your bottleneck, Nudge is the better tool for that specific job. If you need a full accounting system and your clients all pay by card, Wave is a solid choice that won't cost you anything.
The best invoicing tool is the one that removes friction from getting paid. For freelancers dealing with clients across different payment apps, that's Nudge.
