Creating an invoice for services rendered online takes minutes with the right tool. You don’t need expensive software or accountants. Whether you choose a free template or a quick online tool, you’ll have a professional invoice ready to send fast.
Quick Start: Google Docs or Microsoft Word
The fastest approach is a built-in template. Open Google Docs or Microsoft Word, search “invoice,” and pick one that matches your style. Fill in your business name, address, and email, then add the client’s name and address. Add your services, hours or quantities, rates, and let the template calculate totals.
This takes 5-10 minutes per invoice once you’ve set up your first one. Save your filled-in version as a template to skip re-entering your business info. For the next invoice, open your template, change the client name, invoice number, and services, then download as PDF.
Downside: no automatic payment tracking or reminders. But if you send invoices monthly or less, this approach is free and professional.
Wave: Complete Free Invoicing
Wave is a top free invoicing platform. Create an account (no credit card), enter your business info once, and you’re ready to create unlimited invoices. Click “New Invoice,” select the client (or add a new one), add services with rates and quantities, and Wave calculates totals. The interface walks you through each step.
Wave stores all your invoices in the cloud for access from any device. Set payment terms, add late fees, and include notes. Download as PDF or email directly to clients. Wave tracks which invoices are paid so you see at a glance who owes you money.
The platform includes basic accounting and expense tracking for tax time. Wave makes money through optional payment processing, but invoicing is free forever.

Square Invoices: Simple and Fast
Square Invoices is another free, straightforward option. Log into your Square account, go to Invoices, click “Create Invoice.” Add the customer, services, and amounts. Square calculates tax automatically if configured. Send via email and track when clients view or pay it.
Square integrates with their payment processor, so clients can pay directly through your invoice, with money depositing to your account. You don’t have to use payments, but it’s built in. The dashboard shows all invoices and payment status at a glance. Export to PDF if you prefer offline payments.
Zoho Invoice: Feature-Rich Free Tier
Zoho Invoice has a generous free plan with unlimited invoices, basic expense tracking, and automatic reminders. Create an account, fill in your business details, and start invoicing. Zoho’s interface is more polished than Wave with more customization options. You can customize templates, add your logo, and set up automatic reminders.
The free plan includes basic reporting and visibility into which invoices have been viewed or paid. Want recurring invoices or integrations? Their paid plans start low.
Generic Online Invoice Generators
Websites like Invoicingtemplate.com or Canva let you create invoices without an account. Fill in details, customize the look, and download a PDF. These work for one-off invoices but aren’t ideal for regular billing since you start from scratch each time.
Step-by-Step Process for Any Tool
- Gather your info: business name, address, phone, email, tax ID if needed.
- Gather client info: their name, company, and address.
- List services: be specific with hours/quantity, rate, and description.
- Check totals: verify math, especially with tax or discounts.
- Set payment terms: choose Net 15, Net 30, or Due Upon Receipt.
- Add payment methods: show how clients can pay you.
- Review once more: catch typos or wrong amounts.
- Download or send: get a PDF for your records, then send to the client.
Decide Based on Your Volume
Send invoices once or twice a month? Google Docs template works fine. Send weekly or more? Wave or Square saves time and tracks payments. Planning to scale? Zoho or dedicated accounting software pays for itself through automation.
Start free. Most freelancers use free tools forever. Only upgrade when a free tool no longer fits. Waco3 also offers invoicing alongside proposal tracking, so as you grow, keep client work organized in one place.
