Hello I need help creating a DFD with the following business procedure I have provided below:

Business Description:

Eklektic Jewelry Design Studios is a company that handles their customers jewelry needs. Customers are able to create jobs for the piece of jewelry that they want to purchase. The customer gets a chance to customize his/her jewelry by being able to choose stone cut, stone clarity, stone carat, stone type, component color, metal type, metal purity, gold karat, and the component type. Vendors supply the components that are used to customize the jewelry. A customers job can/will create no or many invoices and the invoices can be paid through various payment types. Jobs can produce no or many tasks that are expressed on a shop sheet line. Employees are assigned to shop sheet lines that tell them what tasks to complete. An employee can have many skills that will help them complete the jobs better. In addition, customers are able to add items to their wish list and return items if they are not satisfied.

Mission:

We will focus on the payment process. In the payment process, a customer must first make a job. Once the job is made, an invoice will be sent. Once the invoice is sent, the customer can choose how he/she would like to pay through the payment_type. If the customer decides to pay with a credit card, then the credit card type will be listed on the invoice. The invoice status will tell whether or not the invoice is paid or unpaid. Each customer lives in a state or province that requires him/her to pay taxes. The applied tax percentage will be dependent on the state or province the customer lives in.
