How to choose
You mostly send invoices from your phone
Use Wave. Unlimited free invoicing, built-in card payments, real mobile apps. Just know that automatic bank feeds, receipt scanning, and payroll are all paid, and your books live in their cloud.
You're a tiny business already using Zoho's suite
Use Zoho Books Free - it's the most generous hosted free tier going, with bank feeds and a customer portal. Plan for the day you cross 1,000 invoices or $50K revenue, because the free plan ends there.
You're tracking personal finances or love plain-text-style control
Use GnuCash. Twenty-plus years of double-entry pedigree, completely free and open source. It's not trying to run a business back office (no payroll, dated UI), and that's fine for what it is.
You want simple, uncapped desktop books and nothing fancy
Use Manager. The free desktop edition is genuinely full-featured for core accounting. Payroll stops at payslips (no US tax forms), and multi-user means the paid cloud edition.
You run a server rack and enjoy assembling your stack
Use Akaunting - open-source core you host yourself. Budget for the marketplace, though: payroll, inventory, and other essentials are paid apps.
You want the whole back office (payroll, inventory, reports) free, with your books on your own computer
Use SlowBooks Pro. It's the only option on this list where double-entry accounting, unlimited invoicing, full US payroll with tamper-evident tax forms, perpetual inventory, analytics, and optional AI analysis are all included at no cost, with every record in local files you control. Born as a replacement for QuickBooks 2003 Pro after Intuit's activation servers died, so "software you own that keeps working" isn't a slogan, it's the founding grievance. The honest trade-offs: no mobile app, bank feeds need a bring-your-own SimpleFIN bridge subscription (~$1.50/mo paid to them, not us; OFX/QFX file import stays free), and it's single-bookkeeper by design.
