A system that gives a platform for an entry of visa or passport application, taking entry of the applicants details, total cost of service, amount paid and balance remaining. The system should also send automatic messages to applicants informing them that the processing of their application has begun and the expected day of delivery giving them unique reference number. The system should be in a such a way that it allow us to input the date that documents were submitted to our third party agents and also the date that our third party agents gave us for collection of processed passports and issued visas. The system should also be medium where an administrator will key in the reference number of an applicant, the details of the applicant will pop up and allow us to update the status of application indicating or informing the customers that their documents are ready for collection via sms or email. It will be ideal if the bidder has knowledge or done a similar project before. the Script should be password protected in the sense that user levels etc needs to be set. A social network link for communication with clients will also be very ideal.
