SAP BRIM (Billing and Revenue Innovation Management), now marketed as part of SAP S/4HANA for subscription and usage-based billing, handles high-volume, recurring and usage-based billing for telecoms, utilities, media, SaaS and manufacturers selling “as-a-service”. Its process is often called Quote-to-Cash or Lead-to-Cash.

| Convergent Charging (CC) | Rates and charges usage using pricing plans |
| Convergent Invoicing (CI) | Aggregates billable items into bills and invoices |
| Contract Accounting (FI-CA) | Manages receivables, payments, dunning and collections for high volumes |
| Revenue Accounting (RAR) | Recognises revenue under IFRS 15 / Ind AS 115 |

Top interview questions and answers
1. What is a billable item (BIT)?
A record in Convergent Invoicing representing a charge to be billed, with amount, quantity, contract account and billable item type.
2. Billing vs invoicing in CI?
Billing groups and processes billable items into billing documents; invoicing combines billing documents (and other FI-CA items) into a customer invoice with taxes.
3. What is a contract account in FI-CA?
An account that groups business-partner transactions with common payment and dunning rules; one BP can have many contract accounts.
4. What is a provider contract?
A contract in FI-CA/SOM that links a customer to subscribed products and charging parameters, replicated to Convergent Charging.
5. What does Convergent Charging do?
It rates usage and recurring fees in real time or batch using charge plans and pricing, and sends charged items to CI.
6. What are consumption items?
In newer releases, usage records stored in CI before rating, allowing rating within S/4HANA for simpler scenarios.
7. Why use FI-CA instead of AR?
FI-CA is designed for millions of customers and transactions, mass processing of payments, dunning and correspondence.
8. How does BRIM support IFRS 15?
Through integration with Revenue Accounting and Reporting, which identifies performance obligations and recognises revenue over time.
