Xero

ChatGPT
Invoice Ninja
Invoice Ninja — Best value for technically comfortable freelancers who want extensive customization, many payment-gateway choices, recurring invoices, deposits, a client portal, and the option to self-host; its free plan covers five clients and unlimited invoices.
ChatGPT
Xero
Xero — Best for a freelancer who works closely with a bookkeeper or expects to become a larger business, because it is a serious accounting platform with online invoice payments, but it is heavier and less freelancer-friendly than FreshBooks or Zoho Invoice for simple billing.
