Can the Odoo system provide the following fields and interfaces necessary to permit the following level of integration, and if so, which plugins are best?  

• I need a method for dropping an order file into Odoo for import, the Odoo system must then automatically locate the appropriate customer account based on the billing address
• A client provides orders in a proprietary HTML - I currently have a drop and auto-map function in my current system - how can I drop and drag that into Odoo and have it auto-map? 
• A client provides orders in a PDF format that I will convert to table data - - how can I  automatically import a CSV or Excel file into Odoo?
  
  
• I need a  method for dropping a bulk EFT payment remittance advice file into Odoo for import; the Odoo system must then automatically apply the payments based on the PO number
• A major client provides bulk payment remittance files in an XLSX format that can be dragged and dropped in my current system. All payments are immediately applied - how can l  replicate this automation under Odoo?
• Another client provides bulk payment remittance files in an XLS format that can be dragged and dropped in my current system. All payments are immediately applied presently - I want to replicate this automation under Odoo - how can I do it?
