This ensures consistency, professionalism, and compliance across your transactions.

#### **Receipt Prefix** Add a short prefix (e.g., *EVT*, *GALA*) to be included at the beginning of each receipt number. This makes receipts easier to track and distinguish between different events or campaigns. #### **Starting Receipt Number *****(Optional)*** Choose the starting number for your receipts. By default, numbering begins at **1**. #### **Receipt Logo** Upload your organization or event logo to be displayed at the top of each receipt. A clear, professional logo reinforces your brand identity and helps donors or buyers instantly recognize the receipt. #### **Company / Organization Name** Enter the official name of your organization. This name will appear on all receipts and acts as the sender name for buyers. #### **Company Address** Provide the organization’s full address. This ensures clarity and trust for buyers, as it appears directly on their receipts. #### **Contact Email** Add the email address where buyers can reach your team with any questions about their purchase. #### **Custom Message** Include a short, optional message to personalize your receipts (e.g., *“Thank you for supporting our event!”*). This is a great way to leave a lasting impression. {% hint style="info" %} **Important:** Once your **first purchase is recorded**, the starting number can no longer be changed. {% endhint %} #### **Receipt Email Preview**
