FAQ

Common questions.

What's the difference between the form and Excel upload?

The form is the quickest way — type directly on the page and your templates populate live. Excel upload is better for repeat use: fill your data file once, then upload it every time instead of re-typing. Both produce exactly the same result.

Is my data private?

100%. Everything happens in your browser — form data stays in memory, Excel files are read locally using JavaScript. Nothing is sent to any server. Your business and client data never leaves your device.

What format are the templates?

All templates are single HTML files. Open them in any modern browser — Chrome, Safari, Edge, Firefox. No installs, no account, no subscription. Works on Mac, Windows, and any device with a browser.

How do I save documents as PDF?

Click Print → Save as PDF inside any template. Every layout is formatted for clean PDF output — no cut-off text, no layout issues, no blank pages.

Can I use these for client work?

Yes — all templates are licensed for unlimited commercial use. Use them for your own business, with clients, or across any number of projects. No royalties, no restrictions, no attribution required.

Can I customise the templates?

Yes. All templates are standard HTML/CSS/JS — open in VS Code (free) to change colours, fonts, add your logo, or adjust any layout. No coding experience needed for basic edits.

What's the refund policy?

All sales are final due to the digital nature of the product. If you have any issue with a template, contact us and we'll resolve it — every product is fully supported.
