INTRODUCTION:
Danniel Carton established Mexibills Solutions Pvt. Ltd. 12 years ago in Taxco,Mexico.Commencing with a focus on the bills collection business in Taxco,Mexibills Solutions Ltd.quickly broadened its collection services to other cities of Mexico.The Company outsources its bills collection service to various corporate in town.Its services ease the customers of the corporate by providing door-step collection of their bills.
1.1 EXISTING SYSTEM:
In the existing system,bills are collected through augmented collection channels that are spread in all cities of Mexico.Various cooperates send their collection list to those channels and then according to the location of the customers,collection executives are send by the company for collection of the due bills.This way cooperates are exempted from the back-end peocess of collecting the dues and hence they can concentrate on their main business.
Mexibills Solutions Pvt Ltd.satisfies the customer on behalf of the corporates by providing various services like, reminders for due-bills,settlement of erroneous bills,and bills collection at their door-step.As a result,collection requests are also increasing day by day.
Appointing extra human resources to meet the collection targets is affecting the profit margins of the business.Also,managing the data manually is a tedious process for the company.
1.2 ENVISIONED SYSTEM:
With spring business needs, the currnt system is facing a lot of problems.The human resource is falling short in order to meet the currnet targets.Also,various processes like appointing new collection executives , increasing remainder calls,increasing transport requirements to visit places of collection etc are adding up business operational cost.
The management of Mexibills Solutions Pvt. Ltd. Has decided to build an online system which can help the customers by providing a mechanism for paying bills onbline.
While developing the online billing system the following points need to be taken into considerations:
6
• In the new system,customers need to first register themselves in order to use the services on the online billing system.After registering ,they are authorized to pay bills online.
• The system should have a mechanism to authenticate credentials of the registered customers.This will ensure the security for making payments online.
• The system should archieve all the bills with their up-to-date summary for the customer.
• The payment mechanism has to be online and there should be a provision for accepting the credit card details.
