Most invoice tools look good at first… until you actually try to use them.

As freelancers, we kept running into the same issues:

• Templates were too rigid
• Couldn’t place signature where we wanted
• Number/date formats didn’t match my EU clients
• Could rename fields, but couldn’t change layout
• Free tools added watermarks, ads, or limits

So we built InvoicingBuilder — a simple invoice builder that gives you real control over how your invoice looks and works.

👉 Try it here: https://www.invoicingbuilder.com/

Instead of locking you into fixed templates, you can:

• Customize invoice layout (logo, signature, notes, etc.)
• Rename labels and use your own language (useful for EU and international clients)
• Adjust number and date formats based on region
• Add taxes (VAT, GST, etc.)
• Apply discounts (flat or percentage)
• Include shipping charges
• Add text or image watermarks
• Bulk invoice generator (Excel/CSV to PDF invoice)
• Secured shareable link to send the invoice
• PDF invoices from tracked hours in Clockify, Toggl Track, and ClickUp
• Developer API
• PDF invoices from Notion, Jira, and Asana

It’s designed to handle real-world billing, not just basic demo invoices.

InvoicingBuilder is available as an external add-on in the Clockify Marketplace. Connect your Clockify account, bring in tracked time, map it to your invoice template, and create an invoice without re-entering your time entries.

You don’t have to build everything from scratch. There are ready-to-use invoice templates that you can customize:

• Freelance invoice template
• Standard invoice template
• Quotation template
• Payslip template
• Proforma invoice template
• Freelance writer invoice template

If you’re new or want to understand how things work:

• What is an invoice (beginner guide)
• How to use the invoice builder
• Import Excel or CSV into invoice template
• How to integrate Clockify
• How to integrate Toggl Track
• How to integrate Notion
• How to integrate ClickUp
• Invoice generator API guide

We didn’t set out to build “another invoice generator”.

We just wanted something that:

• Doesn’t get in the way
• Works for different formats and clients
• Supports different languages and regional formats
• Gives control without being complicated

If you’ve ever felt limited by invoice templates, this might be useful.

This is still evolving. If you try it and something feels off or missing, feel free to share feedback.

That’s how this tool got built in the first place.
