Publishing on CostaBooks is easy! Simply create an account, click on "Upload Book" from your dashboard, fill in the book details, upload your PDF, and set your price. Your book will be available in our marketplace after a brief review process.
We currently only accept books in PDF format. This ensures compatibility across all devices and preserves your layout and design. Make sure your PDF is optimized and not larger than 20MB.
Authors receive 85% of each sale. Payments are processed monthly for all sales where the total amount exceeds $20. You can withdraw your earnings via PayPal or bank transfer.
If you're having trouble downloading your purchased book, first ensure you're logged into your account. Then go to "My Orders" in your profile menu. If you still can't access your book, please contact our support team with your order details.
Due to the digital nature of our products, we generally don't offer refunds once a book has been downloaded. However, if you encounter significant issues with the content or if the book doesn't match its description, please contact us within 7 days of purchase for assistance.
