Best Invoicing Software for Solo Freelancers

Every accounting tool we cover handles invoicing to some degree, but a few are specifically strong at it — worth knowing if invoicing (not full bookkeeping) is your main pain point.

What actually matters in invoicing software

• Payment integrations — the ability for clients to pay directly from the invoice via card or bank transfer, rather than needing a separate payment step.
• Recurring invoices — useful for retainer clients, so you're not manually recreating the same invoice every month.
• Automatic reminders — scheduled follow-ups on overdue invoices without you having to remember to send them.
• Read receipts / view tracking — knowing whether a client has actually opened an invoice changes how you follow up.
• Client portals — a place for repeat clients to see invoice history and outstanding balances without emailing back and forth.

How the main options compare for invoicing specifically

FreshBooks is generally considered the strongest for client-facing invoicing polish — professional templates, built-in time tracking tied directly to invoices, and a smooth client payment experience. Wave offers genuinely free unlimited invoicing with solid core features, a strong option on a tight budget. QuickBooks Self-Employed handles invoicing adequately but isn't its primary strength — it's built more around tax categorization and mileage than client-facing polish.

How to choose

If invoicing and client experience is your top priority, FreshBooks tends to win. If budget is the binding constraint, Wave's free tier is hard to beat. If you're already using QuickBooks Self-Employed for its tax features, its invoicing is "good enough" without needing a separate tool.
