Invoice Ninja
Open-source invoicing, free for 5 clients
Invoice Ninja issues invoices, quotes and recurring bills, takes payment through a long list of gateways, and gives the whole thing away for up to five clients with no time limit and no invoice cap. The application is open source, so anybody who would rather hold their own data can run it on their own server instead of paying for the hosted version. Paying lifts the client limit and adds the branding and automation a business wants. Five clients is the ceiling that decides it, and it arrives sooner than most people expect.
Our note
Count your clients rather than your invoices, because that is the limit that actually bites and it arrives sooner than the free plan suggests. Self-host only if you were going to maintain a server anyway, since the hosted Pro plan costs less than the hours will.
Wave
Invoicing and bookkeeping that costs nothing
Wave does invoices, receipts and double-entry bookkeeping for free, and earns on card payments and on a paid tier that automates the parts you would otherwise do by hand. For a sole trader sending a dozen invoices a year it is the cheapest honest answer. Payroll and the advisor service exist in some countries only, which is worth checking before a whole tax year lives in it.
