Self-Hosted Alternatives to Wave Accounting

Why Replace Wave?

Wave Accounting markets itself as “free invoicing and accounting.” The catch: Wave monetizes your financial data. Their privacy policy allows using your transaction data for advertising, product development, and partnerships. When a product is free, you’re the product — and with financial data, the stakes are high.

Updated February 2026: Verified with latest Docker images and configurations.

Wave also charges for payment processing (2.9% + $0.60 per credit card transaction) and payroll ($40+/month). The “free” part is limited to invoicing and basic accounting — which are exactly what self-hosted tools cover.

In 2024, Wave introduced paid plans starting at $16/month for features like receipt scanning and automated bank connections. The free tier is increasingly limited. Self-hosted alternatives give you unlimited invoicing, no data harvesting, and no creeping paywalls.

Best Alternatives

Invoice Ninja — Best Overall Replacement

Invoice Ninja matches Wave’s core features — invoicing, recurring invoices, expense tracking, payment acceptance, and client management — with a more polished interface and no data harvesting. It supports 50+ payment gateways and provides customizable invoice templates.

Invoice Ninja’s self-hosted version is completely free with no feature restrictions. Unlike Wave, your data stays on your server and is never analyzed, shared, or monetized.

Best for: Small businesses and freelancers currently using Wave for invoicing.

Firefly III — Best for Accounting

If you use Wave primarily for its accounting features (bank reconciliation, financial reports, expense categorization), Firefly III is the better self-hosted alternative. It handles double-entry bookkeeping, budget tracking, categorization rules, and financial reporting.

Firefly III doesn’t do invoicing — pair it with Invoice Ninja for a complete self-hosted alternative to Wave’s full feature set.

Best for: Personal finance tracking and small business bookkeeping.

SolidInvoice — Best Minimal Option

SolidInvoice is even simpler than Wave for pure invoicing. Create invoices, send them, track payments. No accounting, no expense tracking, no complexity. If Wave was overkill and you just need to bill clients, SolidInvoice is the right size.

Best for: Solo operators who bill fewer than 20 clients.

Migration Guide

Exporting from Wave

Wave allows data exports via Settings:

1. Go to Settings → Data Export
2. Request an export — Wave emails you a download link
3. The export includes: customers, invoices, transactions, accounts, and journal entries as CSV files

Importing into Invoice Ninja

1. Navigate to Settings → Import/Export in Invoice Ninja
2. Upload Wave’s customer CSV — map fields:

Wave Field	Invoice Ninja Field
Customer Name	Client Name
Email	Contact Email
Address	Client Address
Phone	Contact Phone

3. Upload Wave’s invoice CSV — map invoice numbers, dates, amounts, and line items
4. Set up your payment gateways under Settings → Payment Gateways

Recreating Recurring Invoices

Wave’s recurring invoices map directly to Invoice Ninja’s recurring invoice feature:

1. Go to Recurring Invoices → New
2. Set the client, line items, frequency, and start date
3. Enable auto-send and auto-billing if a payment method is on file

Cost Comparison

	Wave	Self-Hosted (Invoice Ninja)	Self-Hosted (Invoice Ninja + Firefly III)
Invoicing	Free	$0	$0
Accounting	Free	N/A	$0
Payment processing	2.9% + $0.60	Your gateway’s rate	Your gateway’s rate
Paid features	$16/month	$0 (all features)	$0 (all features)
Payroll	$40+/month	N/A	N/A
Infrastructure	Included	$10–30/month VPS	$15–40/month VPS
Data privacy	Data monetized	Full privacy	Full privacy
Annual cost	$0–672	$120–360	$180–480

At $0–30/month for infrastructure, self-hosting costs the same or less than Wave’s paid features while keeping your financial data private.

What You Give Up

• Bank connections — Wave connects to banks for automatic transaction imports. Self-hosted tools require manual entry or CSV imports (Firefly III has some bank connection support via third-party tools).
• Receipt scanning — Wave’s paid tier includes OCR receipt scanning. Invoice Ninja doesn’t have this built in. Firefly III can import receipt data via API.
• Payroll — Wave offers payroll in the US and Canada. No self-hosted tool handles payroll well.
• Accountant collaboration — Wave’s accountant access lets your accountant view your books. Self-hosted requires sharing credentials or exporting data.
• Zero setup — Wave works immediately in a browser. Self-hosted requires Docker setup and server maintenance.

The trade-off is straightforward: 30 minutes of Docker setup gives you private, ad-free, data-sovereign invoicing and accounting.

Frequently Asked Questions

Can Invoice Ninja accept online payments like Wave?

Yes. Invoice Ninja supports 50+ payment gateways including Stripe, PayPal, Authorize.net, Square, and Braintree. Set up your preferred gateway under Settings → Payment Gateways. Clients receive invoices with a “Pay Now” button. The difference from Wave: you connect your own payment processor account directly, so you control the fees (Stripe charges 2.9% + $0.30 vs Wave’s 2.9% + $0.60 per transaction).

Can self-hosted invoicing tools handle taxes automatically?

Invoice Ninja supports configurable tax rates by region, including compound taxes and per-line-item tax rates. You set up tax rules under Settings → Tax Rates, and they apply automatically to invoices. However, it doesn’t calculate sales tax dynamically based on customer location the way some cloud tools do. For US businesses needing automated sales tax calculation, integrate with a tax API like TaxJar through Invoice Ninja’s API.

How do I connect my bank account for automatic transaction imports?

Wave’s bank connection feature doesn’t have a direct self-hosted equivalent. Firefly III supports automatic bank imports through third-party tools like Spectre (Salt Edge) and GoCardless, but availability varies by country and bank. Most self-hosted users import bank transactions via CSV or OFX files downloaded from their bank’s website. This is less convenient but gives you complete control over the data.

Can multiple team members use self-hosted invoicing?

Yes. Invoice Ninja supports multiple users with role-based permissions — you can create separate accounts for accountants, salespeople, and administrators with different access levels. Firefly III also supports multiple users. Neither has per-user fees, so adding team members is free.

Will my accountant be able to access my self-hosted books?

You have several options: create a read-only user account for your accountant, export data as CSV/PDF for review, or set up remote access via Tailscale or Cloudflare Tunnel. Invoice Ninja can also generate profit-and-loss statements, tax summaries, and balance sheets that you can share as PDFs.

Is self-hosted invoicing software secure enough for financial data?

Yes, with proper setup. Invoice Ninja and Firefly III both encrypt data at rest when configured with HTTPS. Run them behind a reverse proxy with SSL, keep Docker images updated, and follow standard security hardening practices. Your financial data is safer on a properly secured server you control than on Wave’s servers — where the business model involves monetizing that data.
