# Wave Review 2026: The Best Free Accounting Software — Just Not for AI-First Teams Wave Accounting review: genuinely free core accounting, invoicing, OCR receipts, and payroll add-ons for freelancers and micro-businesses — but thin AI, a limited GraphQL API, and no official MCP make it the least agent-ready of the big three. ## Resource Links - HTML: https://stack-insider.com/review/wave - Markdown: https://stack-insider.com/review/wave.md - JSON: https://stack-insider.com/review/wave.json - Reviews index (Markdown): https://stack-insider.com/reviews/index.md - Reviews index (JSON): https://stack-insider.com/reviews/index.json ## Facts - Provider: wave - Category: Finance - Rating: 4/5 - Pricing: Free plan available - Signup: https://www.waveapps.com/ - Verified: Yes - Last updated: 2026-10-22 - Agent Readiness Score: 3/7 - API: Yes - Webhooks: Yes - MCP Server: No - OKF Bundle: No - Agent Skill (any harness): No - Agent Skills by harness: None ## Features - Free core accounting: double-entry books, P&L & cash-flow reports - Invoicing & estimates with online payments - OCR receipt scanning - Payroll add-on (US + Canada) - GraphQL API + webhooks (developer.waveapps.com) ## Pros - Genuinely free core — no trial, no paywall on essentials - Everything in one place: books, invoices, payments, payroll - Fast, friendly invoicing for freelancers and micro-businesses - Simple for non-accountants ## Cons - AI is an afterthought (support chatbot, rules-based categorization) - Web-only — no desktop app - Limited API scope and no official MCP server - Support gated to paid users, weekdays only ## Review Content # Wave Review Wave is the free accounting software that's supposed to be a trap — and it isn't. Most "free" accounting tiers are bait-and-switch shells, but Wave has shipped genuinely free, full-featured books since 2009 (owned by H&R Block since 2019) and serves 300,000+ small businesses. If you're a freelancer or creator who needs invoices sent, expenses tracked, and books that won't embarrass you at tax time, this is the smartest $0 you'll ever spend. Just don't come looking for an AI that runs your books — Wave is proudly low-tech where it matters. ## What is Wave? Wave is a web-based accounting and invoicing suite built for owners, not accountants: double-entry bookkeeping, bank and credit-card connections (via Plaid), invoicing and estimates, online payments, OCR receipt scanning, and a payroll add-on. Core accounting is free forever; Wave monetizes through payment fees and paid add-ons. It's web-only — a mobile app for invoices, no desktop app. ## Key Features ### Free Core Accounting Unlimited income/expense tracking, connected accounts, double-entry books, and P&L / balance-sheet / cash-flow reports at $0. ### Invoicing & Payments Invoicing and estimates with recurring billing and deposits, plus a "Pay now" button. Online payments: cards 2.9% + $0.60 (3.4% + $0.60 Amex), bank 1% ($1 min). ### Receipt Scanning (OCR) Snap a receipt and Wave extracts merchant, date, amount, and tax — with automatic categorization on paid plans. ### Payroll & Advisors Payroll add-on (US: $40/mo base + $6 per employee or contractor, with W-2/1099 and tax filing; Canada from $25/mo). Wave Advisors bookkeeping from $149/mo (US). ## AI Features Wave's AI is thin, and there is no real AI bookkeeper here. You get exactly three things, all verified from official sources: **Mave**, an in-app support chatbot (not a financial assistant); **automated transaction categorization** that "learns from your choices" over time (Pro/Receipts plan only); and **OCR receipt scanning**. No natural-language querying, no AI forecasting, no AI-generated reports. Against QuickBooks' AI assistant and Xero's forecasts, it's anemic. ## AI Agent Integration Wave has a real but limited developer story: a public **GraphQL API** (OAuth2, developer.waveapps.com) covering invoices, customers, and accounting transactions, plus official real-time **webhooks** for key events. The API is narrow next to QuickBooks or Xero, and there's no official MCP server. ## AI Ecosystem Integration ### MCP Servers - **No official MCP server.** Every "Wave accounting MCP" on GitHub is a community wrapper over Wave's public GraphQL API — usable, but you own the maintenance risk. ### OKF Bundles - No OKF bundle found yet for Wave. A bundle covering freelancer invoicing and bookkeeping workflows would be valuable. ### Agent Skills - **Hermes Agent / skills.sh / Claude:** no dedicated Wave skills found on official sources. Community opportunity. ### Agent Readiness Assessment - API: ✅ (public GraphQL API, OAuth2 — limited scope) - Webhooks: ✅ (official, real-time) - MCP: ❌ (no official MCP server; community-only) - OKF: ❌ (No bundle) - Agent Skills: ❌ (No dedicated skills) - **Overall Score: 3/7** Wave earns API (+2) and webhooks (+1) — and stops there: no official MCP server, no bundles, no agent skills. Its GraphQL API is narrower than QuickBooks' or Xero's, so an AI-first team would build agent automation on community code. ## Pricing All verified from waveapps.com/pricing and support.waveapps.com (Oct 2026): - **Starter (core accounting): $0** — free forever. - **Wave Pro: $19/mo or $190/yr** (multi-user, auto-categorization, unlimited receipts, discounted fees). - **Receipts add-on: $11/mo or $96/yr.** - **Payroll:** US full-access $40/mo base + $6 per active employee/contractor; Canada from $25/mo base. - **Wave Advisors bookkeeping: from $149/mo** US / $199 CAD (scales with transaction volume). - **Payments:** pay-as-you-go — cards 2.9% + $0.60 (Pro: $0 fee on first 10 transactions/mo), bank 1% ($1 min). ## Who Should Use Wave? - **Freelancers, creators, and micro-businesses** that want solid free accounting - **Anyone who just needs to get paid and stay tax-ready** at $0 - **Not** for teams needing inventory, multi-currency, heavy automation, or an AI bookkeeper ## Final Verdict Pick Wave if you're a freelancer or micro-business that wants solid free accounting and doesn't need inventory, multi-currency, or heavy automation. Pick QuickBooks for deep features and real AI help; pick Xero for a strong API to build on. For AI-first teams, Wave is the least agent-ready of the big three: thin native AI, a limited GraphQL API, no official MCP. But if your budget is $0, Wave remains the best free deal in small-business accounting. Bottom line: the best free accounting software money can buy — just don't expect it to be the smartest.
