Cashflowy vs Wave: Which Is Better for Solopreneurs?

Wave is one of the most popular bookkeeping tools for freelancers and small businesses — and for good reason. It's free, it handles invoicing cleanly, and it gives you basic financial visibility without a monthly fee.

For a solopreneur who's just starting out, Wave is a reasonable place to begin.

The question isn't whether Wave is good. It's whether Wave is enough — and for most solopreneurs past early stage, the answer is no. Here's the honest breakdown.

TL;DR

Wave is free and records what happened to your money. Cashflowy is $39/month and tells you what to do with it.

Wave works well at early stage — under $40,000 in annual revenue with simple finances. Past that, the gaps become real: no Owner's Pay calculation, no Tax Reserve tracking, and no human bookkeeper without paying $149+/month on top.

Cashflowy includes all three at $39 flat. If you're past early stage and still guessing what you can pay yourself each month, that's the gap this comparison is really about.

The Core Difference

Wave is a bookkeeping tool. It records what happened to your money. It does not tell you what to do with it.

Cashflowy gives you the answers you actually need: how much you can safely pay yourself, whether your Tax Reserve is on track, and whether your operating expenses are in proportion to your revenue. Those answers update in real time, on a schedule, with a human available to review the work whenever you need them.

Wave focuses on getting the data in. Cashflowy focuses on telling you what the data means.

Where Wave Is Genuinely Good

Invoicing. Wave's invoicing is clean, professional, and free. For service solopreneurs who send regular invoices, it's one of the better free options in the market. Payment processing is available for a fee.

Basic expense tracking. Connect a bank account and Wave categorises transactions automatically. Functional for simple use cases — one bank, one credit card, straightforward expense categories.

Free. The core Wave product — accounting, invoicing, receipt scanning — costs nothing. For a brand-new freelancer who isn't ready to invest in a paid tool, that's a real advantage.

Occasional invoicing without commitment. If you only invoice a handful of clients a year and don't need financial clarity beyond "what came in and what went out," Wave covers the basics without asking for a monthly fee.

Where Wave Falls Short

Wave records. It doesn't calculate. The gap shows up most clearly with Owner's Pay. Wave tracks your income and expenses. It does not calculate how much you can safely pay yourself after taxes and operating costs are properly set aside. That calculation — the one that prevents the profitable-but-broke cycle — is not part of Wave. For more on why this matters, see why profitable solopreneurs still feel broke.

No Tax Reserve tracking. Wave does not maintain a running estimate of your estimated tax set-aside. It doesn't tell you whether your Tax Reserve is funded for the next quarterly deadline. You track that manually, or you don't track it at all, or you hire someone to track it for you.

No human bookkeeper in the free plan. Wave Advisors — their paid bookkeeping service — starts at $149/month for a human bookkeeper. That's the price of the human layer Wave charges for separately. Cashflowy includes the same access at $39 flat, with no limit on how often you reach out.

No AI on your actual numbers. Wave does not have an AI financial coach trained on your transaction data. Clara AI, Cashflowy's built-in financial coach, answers specific questions about your finances in plain English — your current Owner's Pay number, your top expense categories, whether your Tax Reserve is funded. Wave has no equivalent.

The "free" ceiling. Wave free works to a point. Past $40,000 to $60,000 in annual revenue, most solopreneurs either upgrade to Wave Advisors ($149+/month) for the human layer they need — or they move to a tool that includes it. At $149/month for Wave Advisors versus $39/month for Cashflowy with everything included, the comparison becomes straightforward.

Feature Comparison

How Owner's Pay Works in Each Tool

This is the clearest illustration of the difference.

In Wave: You can see your total income and your total expenses. If you want to know what to pay yourself, you subtract expenses from income and make a judgment call. No allocation percentage. No Tax Reserve deducted. No calculation. Whatever's left is your draw.

In Cashflowy: On the 10th and 25th of every month, Cashflowy calculates your Owner's Pay from your actual Real Revenue — after your Tax Reserve and operating expense allocations are accounted for. You see a number. You transfer it. Done. No judgment call. No guessing. See how Cashflowy calculates Owner's Pay for the full breakdown.

The distinction matters because "whatever's left" is not a reliable number. It doesn't account for quarterly estimated tax deadlines. It doesn't protect your operating expenses. It doesn't build a profit buffer. It's just a balance, and a balance without context is noise.

How Quarterly Tax Tracking Works in Each Tool

In Wave: It doesn't. Wave tracks transactions. Tax Reserve management is your responsibility — a separate spreadsheet, a separate savings account you manually fund, or a guess at year-end.

In Cashflowy: Your Tax Reserve balance is visible on your dashboard at all times — what you've set aside for estimated taxes, updated as revenue arrives. The Q1, Q2, Q3, and Q4 due dates are on your calendar. No surprises. No scramble.

What a Real Customer Said

"I'm a small business owner. I needed something built for me, not something I had to bend myself around. Cashflowy actually feels like someone sat down and asked, 'What do small business owners actually need to know?' They care. They're there for their people." — Todd Trevale, Solopreneur

Frequently Asked Questions

Is Wave good enough for a freelancer? At early stage — under $40,000 in annual revenue — Wave is a legitimate free starting point for basic expense tracking and invoicing. Above that, the missing pieces become expensive in other ways: no Owner's Pay calculation means you're guessing your draw, no Tax Reserve tracking means quarterly payments catch you off guard, and no human bookkeeper means you're either doing the review yourself or paying $149+/month separately for Wave Advisors.

How do I track Owner's Pay in Wave vs Cashflowy? In Wave, you don't — at least not automatically. You see income and expenses. Calculating what you can safely pay yourself requires manual math outside the tool. In Cashflowy, Owner's Pay is calculated on the 10th and 25th of every month from your actual Real Revenue, displayed on your dashboard, and ready to transfer. No manual calculation required.

What does Wave charge for bookkeeping? The Wave free tier includes accounting, invoicing, and receipt scanning. Wave Advisors — their human bookkeeping service — starts at $149/month. Cashflowy includes human bookkeeper access as part of the $39 flat monthly fee, alongside Owner's Pay calculation, real-time Tax Reserve tracking, and Clara AI.

Does Cashflowy track estimated taxes? Yes. Your Tax Reserve balance updates in real time as revenue arrives. The quarterly due dates — April 15, June 16, September 15, January 15, 2027 — are on your dashboard alongside a running reserve balance so you know exactly where you stand before each payment is due.

Can I use Wave for invoicing and Cashflowy for bookkeeping? Technically yes — Wave's invoicing is genuinely strong and some solopreneurs use it specifically for that. In practice, most Cashflowy users consolidate to one platform to keep financial records clean and avoid reconciling across two tools. Cashflowy's built-in invoicing covers standard solopreneur needs.

Will my tax advisor work with Cashflowy? Most will. Cashflowy produces clean categorised expense reports and P&L statements your tax advisor can work from at year-end. If your tax advisor specifically requires a QuickBooks or Xero file, confirm before switching — it's the one scenario where a different tool may be more practical.
