Engagement Overview

As a result of multiple acquisitions, the client currently operates approximately 20 separate billing systems spanning three transaction channels: online (e-commerce), in-showroom (retail/POS), and direct sales team-generated billing. The client''s backend system of record is SAP. We are seeking a functional expert to study the current billing landscape and deliver a findings report with recommendations for consolidation.

•      Mapping of billing workflows, data models, invoicing logic, tax/compliance handling, and payment processing per system

•      Gap analysis against SAP''s billing capabilities (SD, FI-CA, and/or BRIM as applicable)

•      Assessment of data quality and migration complexity (customer master, pricing, tax codes, contracts)

•      Consolidation strategy recommendation (unified SAP billing engine, phased rationalization, or middleware/hub approach)

•      Final report including risk assessment, effort/cost-benefit view, and a phased roadmap

•      Presentation of findings and recommendations to client stakeholders (Finance, IT, and Channel/Operations leadership)

Required Qualifications

•      Direct, hands-on experience on a billing systems consolidation or rationalization project (required — not general SAP implementation experience)

•      Strong functional expertise in SAP billing modules — SD (Sales & Distribution) Billing required; FI-CA (Contract Accounts Receivable/Payable) and/or SAP BRIM/Convergent Invoicing strongly preferred

•      Experience with multi-channel billing environments (e-commerce, retail/POS, direct sales)

•      Background in post-merger/acquisition systems integration

•      Proven ability to produce assessment reports and defend recommendations to senior stakeholders

•      Strong communication and client-facing consulting skills

Preferred Qualifications

•      Experience with legacy retail/e-commerce billing platforms (e.g., Zuora, Vertex, Avalara, Oracle Retail, NCR, or similar)

•      Prior consulting background (Big 4 or SAP-focused boutique advisory firm)

•      Data migration/ETL experience for customer and billing master data
