With the implementation of CDR based customer care and billing project in BSNL certain changes in
the billing and accounting of telephone services has taken place. This document summarizes these
Existing practice: Invoice based billing of landline customers. A customer used get separate bill for
his LL, WLL, ISDN connections. One bill for each service. LL customers get bills for their telephone
charges and payment made by the customer is offset against the invoice (bill) issued to the
customer. Any unpaid bill is shown in the current bill but the outstanding amount is not added to the
current bill amount.
Change due to CDR implementation: The new billing will be based on a customer account. It is also
known as balance brought forward billing. Customer will get a bill similar to GSM bill in which any
previous outstanding dues will be added to the current month bill charges and the amount payable
by the customer includes the previous dues if any.
Now customer can opt and get a single bill for LL, ISDN ,WLL, BB services. This is possible because all
these services can be provisioned in a single account for the customer.
Existing practice: Tariff plans based on MCUs. Customers get certain number of calls (MCUs) as free
depending upon the tariff plan subscribed.
Change: Tariff plans will be based on minutes of usage in the new system. However it has been
decided that till the complete circle migrates to the new system existing tariff plans will be
continued in the billing system. Hence customer will get free usage in terms of rupees instead of free
calls. For example if he was getting 75 calls free , then in the new system he may get Rs. 75 as free
Existing practice: Monthly fixed charges are driven by the exchange system capacity.
Change: new system has lot of flexibility in offering new types of tariff plans. However the linkage
between exchange system capacity and monthly fixed charges is not available in the new system.
All the existing customers will be migrated to the new system with the tariff plan subscribed by them
at the time of migration. System also provides separate tariff plans for rural and urban customers.
Existing practice: For PCOs the minimum guarantee and commission payable is monthly however
the billing is done fortnightly.
Change: In the new system the minimum guarantee as well as commission payable will be
coterminous with billing of the PCO. For example if PCO is being billed monthly then the minimum
guarantee and commission will be calculated on monthly basis at the time of billing. If the PCO is
billed fortnightly then the calculation of minimum guarantee and commission will be done
Existing practice: Late fee(Surcharge on delayed payment) is charged in the current bill after pay by
date on slab basis.
Change: Late fee will be charged in the next bill on basis of % of dues.
Existing practice: Free call calculation is done on the monthly basis even though bills are issued on
bimonthly basis to customers.
Change: In the new system the free call calculation / discount calculation will happen at the time of
billing the customer depending on his billing cycle.
Existing practice: Bills for various services for a corporate customer issued separately.
Change: The new system has provision for providing Electronic stapling to corporate customers. A
corporate customer can get single e stapled bill covering LL, GSM ,leased line , BB services.
Presently the existing billing system offers a facility for group bill to the customer. The same facility
can be provided through electronic stapling to the customer provided he makes a single payment for
the electronically stapled bill. Before migrating any group bill customer to Electronic stapling the SSA
must apprise the customer changes happening due to electronic stapling. He must be made aware of
the terms and conditions of E stapling. These are given in the following document.
However if presently group billing is used for just grouping the bills together so that the bills are
dispatched to customers together then electronic stapling should not be used. Electronic stapling
should be used only when a customer ( a corporate customer ) who has number of services and
wants a single bill and would like to pay through a single check for all the services he has availed.
Existing practice: Disconnection of phones for non payment of dues controlled by AOTRs of the
Change: In the new system disconnection and reconnection will be controlled by the software and
the category of the customer. If the payment for a bill is not received by pay by date then the
customer will be moved to collections (dunning) module of the system and will be disconnected on a
specified date if the payment is not received. IF the payment is received then system will
automatically reconnect the customer. AOTR will have access to issue reconnection orders in case of
wrong disconnection. Also AOTR can use promise to pay feature so that disconnection activity does
not happen on a customer.( for example police, local hospital number etc.)
With this the important job of the SSA will be to update the payment received in the system
especially for offline payment channels like post office , banks drop boxes etc. to avoid wrong
Existing practice: Acceptance of payments at SSA for cu stomers of concerned SSA. Generally
payments from the customers of SSA only are accepted in the SSA.
Change: Now a payment management system will be available for a zone. Hence payments can be
accepted across the zone. For example circles MH, GJ, MP, CG are served from Pune Data centre for
CDR project. A customer of MH can make payment at GJ or MP or CG.
Existing practice: Presently there is no integrated accounting system is available. Accounting of
revenue and payment collected is dependent on the Sub ledger report generated from the SSA
based billing system.
Change: An integrated accounting system is implemented in the new system. In south and East zone
Oracle financials and in north and west zones SAP FICO module are implemented. The out put of the
accounting system will be revenue trial balance for the SSA. This TB then can be merged with
expenditure TB for the SSA to obtain its complete TB.
As already mentioned above the customer can have single account and can get a single bill for all
services like LL, WLL, BB that he has availed. The accounting system maintains LL debtors and BB
debtors. Hence when a customer gets a single bill for his LL and BB services the system allocates
payment received and then sends information to accounting system at the consolidated level so as
to maintain LL and BB debtors separately. The debtors for WLL , ISDN are not maintained separately
but are merged with LL debtors. With integrated revenue accounting certain new account codes are
introduced by Corporate Office by circular 190 and 209. These are given below for reference. With
the introduction of new codes the AO Cash of the SSA has use the code given in the circular 190 for
telecom revenue related receipts since the classification will be done by the system based on inputs
from PMS and billing system.
Circulars issued by Corporate Office on account codes.

Since the account based system is being implemented sub ledgers for WLL, ISDN will not be
available separately. However revenue generated for Each WLL, ISDN are available. Also plan wise
revenue report for BB plans is available. The excel file furnishes the SLR reports which will not be
available in the new system with comments of IT circle .
