Invoices include total amount in words and a PAID/DRAFT watermark based on payment status.

Best for: Freelancers, contractors, and anyone who needs a fast invoice without creating yet another online account.

2. Wave — Best Full Free Accounting Suite

Wave is a comprehensive free accounting platform that includes invoicing, expense tracking, and basic payroll. It's an excellent choice if you want to manage your entire small business finances in one place. However, it requires a free account signup, and the interface can feel overwhelming for someone who just needs a quick invoice.

Best for: Small business owners who want combined invoicing and bookkeeping.

3. Zoho Invoice — Best Free Tier with Advanced Features

Zoho Invoice offers a generous free tier for businesses with fewer than 5 customers. It includes recurring invoices, payment reminders, and a client portal. The downside is you must create a Zoho account, and it can take 10–15 minutes to get set up.

Best for: Small businesses that invoice the same clients regularly and want automation features.

4. Invoice Ninja — Best Open-Source Option

Invoice Ninja is an open-source invoicing platform with a strong free tier. It supports unlimited invoices, clients, and quotes. You can self-host it for complete control over your data. The UI is more complex than other tools.

Best for: Tech-savvy freelancers and agencies who want full control or self-hosting capability.

5. PayPal Invoicing — Best if Clients Pay via PayPal

PayPal's built-in invoicing tool is convenient if your clients already use PayPal. You can send a professional invoice directly from your PayPal account and the client can pay online. The main limitation is that it requires both parties to have PayPal accounts.

Best for: Freelancers whose clients prefer paying via PayPal.

If you need an invoice right now, with no signup and no setup, InvoiceFast is the fastest way to get there. Fill in your details, click Download PDF, and you're done. For ongoing business management with bookkeeping needs, Wave or Zoho Invoice are worth the signup.
