Integration Details

Integration Scope

Billing service can be integrated with any organization or system that wants a demand-based payment system.

Integration Benefits

• Easy to create and simple process of generating bills from demands

• The amalgamation of bills period-wise for a single entity like PT or Water connection.

• Amendment of bills in case of legal requirements.

Steps to Integration

1. Customer can create a demand using the /demand/_create

2. Organization or System can search the demand using /demand/_searchendpoint

3. Once the demand is raised the system can call /demand/_update endpoint to update the demand as per need.

4. Bills can be generated using, which is a self-managing API that generates a new bill only when the old one expires /bill/_fetchbill.

5. Bills can be searched using /bill/_search.

6. Amendment facility can be used in case of a legal issue to add values to existing demands using /amendment/_create and /amendment/_update can be used to cancel the created ones or update workflow if configured.

Apportioning FAQs

What is apportioning?

Adjusting the receivable amount with the individual tax head.

Types of apportioning V1.1

Default order based apportioning(Based on apportioning order adjust the received amount with each tax head).V1.1

Types of apportioning V1.2: (TBD)

• Proportionate based apportioning (Adjust total receivable with all the tax head equally)

• Order & Percentage based apportioning(Adjust total receivable based on order and the percentage which is defined for each tax head).

Principle of apportioning

The basic principle of apportioning is, if the full amount is paid for any bill then each individual tax head should get nullify with their corresponding adjusted amount.

Example: Case 1: When there are no arrears all tax heads belong to their current purpose:

Case 2: Apportioning with two years of arrear: If the current financial year is 2014-15. Below are the demands

if any payment is not done, and we generating demand in 2015-16 then the demand structure will as follows:

Overview

The consumer sometimes needs additional amounts (Amendments) added to their bill due to reasons from outside of the system. The addition of amounts happens with respect to the consumer code of the entity in the product(PT, WS, etc..,), any unpaid demand in the system is a candidate for amendments.

Pre-requisites

• Prior Knowledge of Billing-Service in Digit framework.

Key Functionality

Amendment mainly works with two types of functionality as follows:

• Amendment

• Demand

Bill Amendment provides a separate flow to enable workflow and validation for the process of adding additional amounts into the existing demands which were done through the respective modules only till this point in time. An amendment will be allowed only when the reason arises from out of the system to add or reduce the amount from the existing bill belonging to an entity. The reasons are as listed

1. Court case settlement

2. One time waiver

3. Write-offs

4. DCB correction (Old demands in paid status)

5. Remission for Property Tax

Criteria:

There are certain prerequisites to create an amendment,

1. presence of demand in the billing system

2. One of the Reason as Listed above

3. Valid document proof for the reason

4. No other Amendment already in workflow

Procedure:

The process of adding Amendment is as follows

Please follow the scenarios and let me know in case of doubts. There are two scenarios on how an amendment will be completed which is based on the paid status of the existing demands in the system.

1. when demand is unpaid/partially paid

1. create a demand (Or an existing demand can be used) with demand detail → DD1.

2. Do not pay the bill or make payment partially.

3. Create an amendment for the same consumer-code (with demand detail → DD2).

4. approve the amendment, the response should return an amendment with status CONSUMED.

5. search the demand or fetch bill for the consumer-code, demand/bill should contain demand details of demand and amendment together DD1 and DD2 in the same demand/bill.

2. when demand is completely paid,

1. create demand and make complete payment or choose a consumer-code which is fully paid.

2. create amendment (with demand detail → DD1).

3. Approve amendment, the response should be APPROVED this time.

4. create new demand for the consumer -code (with demand detail → DD3), demand response should contain two demand details DD1 and DD2 saved to the demand.

5. Now amendment search will return CONSUMED status after the demand is created.

IMPACT: Does not impact any other functionality other than adding demand details to demands on APPROVAL.

IMPACTED BY: Existence of demands in the system.

Integration Details

Integration Scope

Amendment integration helps the respective Organization to add additional value to the demand without any change in the system.

Integration Benefits

• Easy to create and simple process of updating demands

• helps ease changes into the system which are not part of normal functionality - Amendment of bills in case of legal requirements.

Steps to Integration

This is integrated into the billing system by default.

1. Amendment facility can be used in case of a legal issue to add values to existing demands using /amendment/_create and /amendment/_update can be used to cancel the created ones or update workflow if configured.
