INVOICE GENERATOR WITH QR CODE (dora)

I need an invoice generator which includes but not limited to: * 5 users (1 administrative who can edit the previous orders or cancel them and create new users and change passwords+ 4 sellers who can only generate the invoices). * Access can be all users in same computer, I really dont care by now. * Input orders: -Invoice number (autogenerated consecutive) -Customer name and address (text) -Customer SAT number (number + letters) -Date (autogenerated, takes computer's date) -Quantity (number) -Code (number + letters) -Operator (text) -Description (text) -Unitary Price (number with 2 decimals) -Import (autogenerated: Unitary Price * Quantity). -Subtotal (auto generated: Sum of imports) -VAT (user enters a percental number, software will calculate the vat according to the input of user). -Total (autogenerated: sum of subtotal + vat) -Payment form (multiple choice 7 options) text is a space including letters, numbers and special charachters (for example but not limited to accents in spanish). The app, when user runs the invoice generated it must ask for all spaces filled, no white blankets allowed in the fields to be filled. Once it is finished, will generate an invoice with QR code (including: username + customer + description + total) OUTPUT INVOICE MUST BE LIKE ATTACHED FILE, ALSO SOFTWARE AND OUTPUT SHOULD BE IN SPANISH I'LL BE GLAD TO HELP YOU IN THE SOFTWARE TRANSLATIONS IN CASE OF NEED. FINAL DELIVER MUST BE THE CODE + THE APP RUNNING APP MUST BE CAPABLE OF SUPPORT SPANISH PUNCTUATION SYMBOLS. CODE AND APP WILL BE COPYRIGHTED
