Lead-to-Cash Flow

The complete Lead-to-Cash process flow mapped to eTOM, with system ownership at each step.

Last updated 14 Oct 2026

Section 1.4 introduced Lead-to-Cash and its sub-domain processes. This section maps the L2C flow to specific eTOM process areas, system responsibilities, and API interactions — showing how each sub-process executes in practice.

The Complete L2C Flow

The Lead-to-Cash flow can be broken into eight major stages. Each stage has a primary system owner, specific eTOM process mappings, and TM Forum API touchpoints. Understanding this flow end-to-end is essential for any BSS/OSS architect.

Lead-to-Cash: End-to-End Flow

1
Marketing & Campaign
Marketing / Product Catalog

Define target segments, create campaigns, and generate awareness. Product offerings are defined in the catalog and made available to channels.

2
Lead Capture
CRM

Capture prospect interest from campaigns, web, retail, or partner channels. Qualify leads and assign to sales resources.

3
Opportunity Management
CRM

Convert qualified leads into sales opportunities. Identify customer needs and map to appropriate product offerings.

4
Configure, Price & Quote
CPQ / Product Catalog

Build a valid product configuration, apply pricing rules, and generate a formal quote. Validate feasibility and eligibility.

5
Order Capture
COM (Commercial Order Management)

Convert accepted quote into a formal commercial order. Validate completeness, enforce the credit and identity checks (which may have run earlier, at the basket), and submit for fulfilment.

6
Order Decomposition & Orchestration
SOM / ROM

Decompose the commercial order into service orders (CFS-level) and resource orders (RFS-level). Orchestrate the fulfilment sequence.

7
Service Activation & Resource Provisioning
SOM / ROM / Network Activation

Activate CFS instances in Service Inventory. Provision RFS instances and configure network resources. Run automated testing.

8
Billing & Revenue Collection
Billing / Revenue Management

Activate billing for the new service. Generate the first invoice. Collect payment and recognise revenue.

Stage-by-Stage Breakdown

Each L2C stage has a clear owner, eTOM mapping, and handoff point. Navigate through the stages below.

Stage 1: Marketing & Campaign

BSS

Define target segments, create campaigns, and publish Product Offerings to channels via the catalog. eTOM: Marketing Fulfilment Response (1.1.1.1). APIs: TMF620 (catalog), TMF658 (loyalty). System: Marketing Platform + Product Catalog.

L2C Flow Variations

Not every L2C flow follows all eight stages. The flow varies depending on the sales channel, customer type, and product complexity:

  • Customer performs their own CPQ — stages 2-3 compressed or eliminated
  • CPQ logic runs in digital frontend via BFF APIs
  • Requires fully automated zero-touch fulfilment end-to-end
  • Typical for simple consumer products (mobile, broadband)

Lead-to-Cash — Key Points

  • L2C is the primary value chain: Marketing → Lead → Opportunity → Quote → Order → Fulfilment → Billing → Revenue
  • It traverses the entire eTOM Fulfilment vertical across CRM, SM&O, and RM&O layers
  • The BSS-to-OSS handoff happens at order decomposition: Product Order → Service Order → Resource Order
  • TMF622 (Product Ordering) is the critical API at the BSS/OSS boundary
  • CPQ must include feasibility checks (TMF645) to prevent order fallout
  • Catalog-driven decomposition eliminates manual translation from commercial to technical
  • Billing should be activation-triggered, not order-triggered
  • The flow varies by channel (self-service, assisted, partner) but the stages remain the same
