How to make your own invoice generator (free, print-ready)
~6 minutes · no code · free to start
Freelancers pay $10–30 a month for invoice tools that do one thing: put numbers in a nice layout. You're about to make your own — with your details remembered, your tax rate, your layout — for free, in the time it takes to make coffee.
Paste the description, and two minutes later you're typing your first line item.
What you'll end up with
- ✓Your business details and your client's, remembered between visits
- ✓Line items with quantities and prices, totals calculated live
- ✓Configurable tax rate and optional discount
- ✓A live preview that prints exactly as shown — Save as PDF from the print dialog
The five steps (same for every app)
- 1
Describe it
Type what you want in plain English — like you'd explain it to a friend. No technical words needed. Every guide below gives you a ready-made description you can use as-is or edit.

Check the plan
Kyntra replies with a short plan in plain English: what it understood and what it's about to build. If it got something wrong, just say so. Happy? Hit Approve. (You can switch on Auto later to skip this step.)

Watch it build
About a minute later your app appears in the preview panel — a real, working app, not a mockup. Click around in it right away.

Ask for changes
This is where Kyntra is different from hiring anyone: changes are just sentences. "Make it blue." "Add a delete button." "That chart is confusing, make it simpler." Each change takes about a minute, and every version gets a quality grade in the header — Kyntra checks its own work for the mistakes AI builders usually make.
- 5
Publish it
One click on Publish gives your app a real web address you can send to anyone or open on your phone. Change something later? Publish again — same address, new version.
Your ready-made description
This is the exact text the button below pastes for you — read it, edit anything, or use it as-is.
An invoice generator. Form for my business details and the client's, invoice number and dates, then line items (description, qty, unit price) with add/remove rows. Live totals with configurable tax rate and optional discount. A live preview pane shows the invoice exactly as it prints; a Print/Save-PDF button uses the browser's print with print-specific CSS so only the invoice prints. Remember my business details in localStorage.
Make it yours — things to say next
After the first build, changes are just sentences in the chat. For example:
You say: “Add my logo at the top — here's the image URL”
→ Branded invoices
You say: “Add an invoice history list so I can reopen past invoices”
→ A filing cabinet, built in
You say: “I invoice in euros and my tax line is called VAT at 19%”
→ Localized for how you actually bill
You say: “Add a 'paid' stamp toggle”
→ The small satisfying things
Common questions
Is this safe for client data?
Everything stays in your browser on your computer — nothing is uploaded anywhere. That's more private than most invoice SaaS tools.
Do I need to know how to code?
No. You describe, Kyntra builds. You never have to read or touch code — though it's all there if you're curious.
Is it really free?
Yes — free to start, no card. The free plan includes 5 apps and 25 builds a day, which is plenty to build and polish something real.
How do I know the app is any good?
Every version is audited by Kyntra's 17-check quality engine — the same kind of review a senior engineer would do — and stamped with a letter grade you can see in the workspace header.
Five minutes from now, this exists.
