Business License Calculator

Overview

Business License Calculator service is used to calculate the Trade license fees/renewal fees based on the defined billing slabs. This service enables the TL admins to create billing slabs with different combinations of license type, trade type, structure type and accessory type. The service is designed in such a way that it can be used to serve different types of licenses.

Pre-requisites

Before you proceed with the configuration, make sure the following pre-requisites are met -

Java 8
Kafka server is up and running
egov-persister service is running and has tl-calculation-persister & tl-billing-slab-persister config path added in it
PSQL server is running and a database is created to store TL Application data
Following services should be up and running:
- egov-perister
- egov-mdms
- tl-services
- billing-service

Key Functionalities

TL Admin an Employee of ULB with TL_Admin role can create, update billing slab(s)
ULB Employee with TL_CREATOR and TL_ADMIN can search billing slab(s)
TL service internally calls tl-calculator to generate demand.

Deployment Details

Deploy the latest version of tl-service and tl-calculator
Add tl-calculation-persister.yml & tl-billing-slab-persister.yml file in config folder in git and add that path in persister . (The file path is to be added in environment yaml file in param called persist-yml-path )

Integration Details

Integration Scope

tl-calculator will be integrated with tl-services. tl-services internally invoke the tl-calculator service to calculate and generate demand for the charges.

Integration Benefits

Tl calculator application is used to calculate the Trade license Fees based on the different billing slabs in the DB that's why the calculation and demand generation logic will be separated out from TL services. So in future, if calculation logic needs to modify then changes can be carried out for each implementation without modifying the TL services.

Steps to Integration

TL application to call /tl-calculator/v1/_calculate to calculate and generate the demand for the TL application
ULB Employee can create billing slab calling /tl-calculator/billingslab/_create
ULB Employee can update billing slab calling /tl-calculator/billingslab/_update
ULB Employee can search billing slab calling /tl-calculator/billingslab/_search
