Before you write about an order
Please include your Razorpay payment ID. It begins with pay_ and appears on the receipt Razorpay emails you, and on your download page. With it we can find your payment in seconds; without it, it takes a good deal longer.
Lost your download, or the link expired? Do not email about it — use the request form. It collects exactly what is needed to verify your payment, which makes it far quicker than a back-and-forth by email. You will not be asked to pay again.
What we can help with
- A payment that went through but did not deliver the book — the request form is the fastest route.
- A duplicate charge — see the Refund & Cancellation Policy.
- An expired or broken download link.
- A PDF that will not open.
- A request about your personal data — use the data request form.
- Anything you would like to see on the shelf next.
What we cannot help with
We cannot give personalised business, legal, financial or tax advice, review your idea or your startup, or promise that anything in a book will work for your situation. The Terms & Conditions set out what is and is not claimed.
