***
### Create a Sales Bill with Prescription Details
* Open the **Sale Bill – Touch Screen** module.
* Enter the **patient details** along with the **doctor’s name**.
* Specify the **prescription validity in days**.
* For example, enter **10 days**.
**Attach the Doctor’s Prescription Document**
* Click on **Attach Document**.
* Select **Document** and use the **browse icon** to upload the prescription image from your system.
* Optionally, enter:
* Document title

* Remarks
**Camera Capture Option**
* You can also scan or capture the prescription using a **webcam**.
* Select the required **camera and resolution**.
* Click **Take Picture** to capture the prescription instantly.
* Click **Save** to store the prescription.
* The entered prescription details can be viewed in the prescription section.
**Enter Items with Prescription Type**
* Scan or enter the items.
* Select the **Prescription Type**, such as:
* **OD** – Once Daily

* **TDS** – Three Times a Day
* **QDS** – Four Times a Day
* Select **OD**.
* Once selected, the system automatically calculates and updates:
