Frequently asked questions
Is it free?
Yes. Creating, editing and downloading PDF, PNG and JPG files is free, with no watermark and no subscription.
Can I change the design afterwards?
Yes. Open the result in the ZeoCanvas editor: every heading, photo, shape, colour and page stays editable.
Is it GST compliant?
It includes the GST fields and calculations, but it does not verify GSTINs or rates. Check the result meets the rules for your business.
Can I keep everything for one client together?
Yes. Create an interior project for the client and link moodboards, plans, material boards, estimates, proposals, presentations and invoices to it. The project dashboard shows them all, with the room list and budget summary.
Do I need an account?
No. Guests can create and download straight away; guest work is kept for a limited time after the last visit. A free account keeps projects and your material library permanently.
