Authorize.net Interface plugin WooCommerce DPM Authorize.net - SIMPLE not a shopping store - Repost

Webpage is: [login to view URL] I need the following project: I have a [login to view URL] account. I currently have a WooCommerce and Yak plugin both installed and i dont know if i need either, or both, or none. I have purchased WooCommmerce DPM --- I have my [login to view URL] API information, it needs interfaced properly All i need is simply this: Please note this is not a shopping cart or any fancy web store... For clarification the customer will goto the website and i want forms to be there saying 1) Enter Invoice Number and invoice amount. The customer ALREADY has the invoice on hand, and the amount. This project does not tie into any billing system or anything like that... I also want them to have an option to check "Multiple Invoices". If there are multiple invoices then there will automatically be 3 or 4 more boxes open where the customer will put additional invoices and amounts. Then, your coding will add up the total and they will "Continue" to the next process that will auto populate with the invoice #'s, and the total amount will auto populate into the payment form. Then the payment form will be WooThemes [login to view URL] DPM and [login to view URL] information. And now the customer can simply put in their information and Credit Card info and submit and it routes payment through my [login to view URL], and notifies me via email of the invoice #'s paid and the transaction info from [login to view URL] ... I dont know if im making this sound more confusing then it has to be??? i am also open to suggestions. Then I need the YAK or WooCommerce plugins removed IF i dont need them Then I need to test it and make sure its working. Thank you
