Rendered from the same template. Sample data. A4 · 210 × 297 mm

Switch the record. The template holds its layout — the line items grow, the currency and dates reformat, and nothing about the call changes.

Built for the people who own the wording.

Product, ops, and finance change the invoice, the dunning letter, and the payment email themselves. No ticket, no template language, no waiting on a deploy.

The template editor editor.shablonix.online
The Shablonix visual editor open on a Professional Invoice template: an Atoms rail on the left, a true-size A4 canvas in the centre showing a Northstar Design Studio invoice, and Inspect on the right.
  1. Atoms Text, tables, images, repeaters, conditionals. Drag them onto the page — nothing here requires template code.
  2. Page canvas A true-size A4 document. What you arrange here is what renders in the finished PDF.
  3. Inspect Select any atom to tune spacing, style, and page flow without leaving the page.
Bindings
Insert a field at the caret. Nested values and repeating rows included.
Format
Currency, dates, and names formatted per document, not per spreadsheet.
Preview
Resolve every expression against your JSON before anything ships.

One editor. The page, the inbox, the web.

The same atoms, bindings, and styles produce a print-exact PDF, table-based inbox HTML, or a responsive website. Learn the editor once; ship all three.

Websites from the same data

Responsive pages with navigation, rooms, galleries, and sections you can switch off — bound to a record your system already keeps.

One record. Ten hotels.

Ten complete hotel websites, each reading the same rooms, amenities, reviews, and gallery data. Swap the design without touching the data — or feed one design a hundred different hotels.

Letters that still go in the post.

Print-and-mail services such as Pingen, Stannp and Docsaway reject letters whose address strays out of its box or into the franking area. Our letter starters are laid out for those rules: the editor shows the zones while you work, and the PDF carries only the letter.

Postal letters

Your engineers write one call.

template_id + data. When someone moves the logo or rewrites the terms, that call doesn't change — the work stays in the editor.

Why we built Shablonix

We came out of FinTech invoicing and collections, where every wording change on an invoice waited on engineering. So we gave the template to the people who write it.

A small team that still customizes the product when the starter isn't your document.

Tell us what you need to generate

Published prices. Published overage.

Every plan includes the visual editor. You pay for the documents you generate, and extra documents cost a fixed, listed rate — not a custom quote.
