Okidata Mexico hired Hexacta to develop PPI (Pay for Impression), which is an application that gives support to a new leasing business regarding printing equipment for the Mexican SMEs.
Okidata offers Mexican companies a payment scheme according to the amount of printed pages during a certain period of time, adjusted to their particular needs.
PPI is designed to support all the business processes from capturing data of a potential client, to controlling the number of impressions and the maintenance of the equipment.
PPI web application was developed under the .NET platform and it consist of different modules to track prospects and clients, create contracts to lease equipment, stock reports, alarms to anticipate toner changing, among others.
Access to information in the database and the business logic of each screen depends on each user’s role within PPI.
PPI architecture is based on a development in layers, it caches information in order to increase efficiency, encrypts data, handles exceptions and sends emails.
PPI has two external modules: one module consists of several alarms, each of them configurable. The other module exports and imports the contract’s payments from and to the client’s bank and the invoicing system.
PPI provides reports using the Active Report tool and uses LinqToSql to manipulate data, allowing to work with information stored in a relational database using the paradigm of object-oriented programming.
The project nowadays is at a maintenance phase with implementation of new functionality. Its current team consists of two developers, a functional analyst and a tester.
