Zoho Invoice is completely free invoicing software — not a free trial, not a freemium plan with crippled features, but a fully functional invoicing product that Zoho offers at no cost permanently. For freelancers and small businesses that need professional invoicing without the expense of FreshBooks or QuickBooks, Zoho Invoice is the most capable free option available.
It handles the full invoicing workflow — creating professional branded invoices, sending them automatically, tracking which invoices are viewed and paid, sending payment reminders for overdue invoices and accepting online payment via credit card, PayPal and bank transfer. Time tracking is built in, letting you log hours and convert them directly to invoices for hourly billing.
Zoho Invoice integrates with the broader Zoho ecosystem — if your business grows to need CRM, HR or full accounting, you can add Zoho Books (accounting), Zoho CRM and other products. For businesses already using any Zoho product, Invoice slots in seamlessly. The mobile apps for iOS and Android are well-designed and let you create and send invoices from your phone.
