Some features for Odoo and Openeducat Ver 9

We would like some guidance regarding your system. We have a few questions about the services your system provides. They are as follows: (1) The first is in regards to your SALES/CRM module: We are using this module to work in our day-to-day operations in the school. We would like to know if it would be possible to have the 'customer' option available in the menu 'student' and menu 'admissions' option. This is because our customer has to be tracked in our system. So if we create a new customer we will be able to view them in the 'admissions', 'student' and 'customer' table. When we setup a new student we can search inside the screen on the student table by Customer (Today we are able to do this kind of search but the view doesn't work)... (2) The second questions is regarding our attendance. We have a model that is shown like a color dashboard . Our courses are in general , 25 weeks (125 days) long. According to.... Our current system calculates the amount of classes that a student has attended and missed and then gives us a percentage. For example, Student “A” has 250 classes but has been absent for 20 classes. Therefore they have an final attendance of 92% (250-20=230, 230*0.4=92%) ***(250 classes = 125 days because each day equals 2 classes ) In days : We need to see and be able to show them, their attendance dairy. For example of a total 125 days , if a student absent of 10 days , and He has had 88 days then your actually attendance will be 70.4% and He have 27 days left yet , because ( 125 -10 = 115 days current and 115-88 = 27 days ( or 54 classes) for come in yet . Thus, we have to show an attendance record as well in percentage for each student we have enrolled in the school... 2.1- Since a student's attendance is so important, we have to take into consideration other factors which will affect their attendance... We can send you our attendance model, but if you did not understand this issues/request , please contact me , before our conversation by Skype or Phone. (3) The third requirement is about LEADS, that is a menu of SALES/CRM. We would like that an email with a request about everything that comes from the website will be uploaded to the menu screen " Leads " (7) The seventh requirement is a customized dashboard with specific information HEADINGS about the business , like Financial information like customers payments , accounts payables for the bills We need pay soon ,... (8) The eighth requirement is two news fields in Quotations/invoices on Sales module that once fill , we can filled the enrolment module with this information ... (9) The ninth requirement is a module of instalment payments for account receive for odoo 9 . This module is available for Odoo version 8 but not yet for Odoo 9 Version. (10) tenth requiment is a improving of APK for student for Mobile OPENEDUCAT . Today Openeducat have a good mobile apk , but we need everthings regarding letters , attendance , and informations of interest students. We could have this features/requirements in the Openeducat version 9 . Therefore, we need the right tools in order to operate smoothly and without any mistakes or problems. As usual, we can communicate by email . Best regards
