Applicable to all e-book downloads, proprietary publications, and digital blueprints.
Zenvo Technology e-books are digital products, delivered as soon as your payment is confirmed: the book is added to your account library, where you can read it online or download a PDF copy. Every copy is personalised with a watermark showing your email address and order number.
To ensure complete transparency and prevent buyer remorse, Zenvo Technology provides a free 3-page preview of every e-book before purchase. Please read the preview and the book description to confirm the book suits you before paying.
If GST was charged on your order, an approved refund is accompanied by a GST credit note referencing the original Tax Invoice, reversing the CGST and SGST or IGST. If no GST was charged (your document is a Payment Receipt marked “Not registered under GST”), no credit note is needed. A refund ends access to the book.
