Wave is free. PingPaid gets you paid. Wave offers excellent free invoicing for small businesses. But when invoices go overdue, Wave leaves you writing manual follow-up emails. Here's how they compare for the critical task: getting money into your bank account.
Wave's philosophy: "Create professional invoices for free." PingPaid's philosophy: "Turn every invoice into collected revenue automatically." These are fundamentally different jobs. Wave is an invoicing tool. PingPaid is a collection engine.

Wave is genuinely free for invoicing and accounting. But here's the hidden cost: time spent on manual collection. Freelancers using Wave report spending 4-8 hours per week on payment follow-up. At a conservative €40/hour billing rate, that's €160-€320 per week in opportunity cost — or €8,320-€16,640 per year in lost billable time.
Add to that the invoices that go uncollected because follow-up is inconsistent. Wave has no automated escalation. No late fee calculation. No legal pressure. Just you, writing emails, hoping clients respond.
Wave is perfect if: You have fewer than 5 clients, all pay on time, you need basic accounting, and you enjoy (or don't mind) writing follow-up emails manually.
Add PingPaid when: You have 5+ clients, any invoices go past 30 days, you spend more than 1 hour per week on payment follow-up, you've ever written off an unpaid invoice, or your cash flow is unpredictable due to collection timing.
Wave (free) + PingPaid (€29.99/month) = €359.88/year
Time saved: 200+ hours/year (4 hours/week × 50 weeks)
Opportunity cost saved: €8,000+/year (at €40/hour)
Average additional revenue recovered: €1,847 in first 30 days
ROI: 5,000%+ in year one.
How many hours do you spend chasing payments? Multiply by your hourly rate. That's what "free" invoicing actually costs.
