Refund Policy

Effective: August 6, 2026

Because digital products can be accessed immediately, we generally do not offer change-of-mind refunds after access or download has been provided.

Cases we will review

• The same order was charged twice.
• The wrong product was delivered.
• A delivered file is damaged or cannot be opened.
• Payment was taken but access was not provided.
• There is a material difference between the product description and the delivered files.

Requesting review

Email support@sankobusinesslibrary.com with the order details and a clear description of the issue. We may request reasonable information needed to verify the request.
