Summary:
As an SAP SD Billing Consultant, you will hold design authority and delivery accountability for the process area, leading multiple workstreams through their Managers while remaining personally hands-on on the hardest design and configuration for Billing within the Commercial / Order to Cash tower of the DRS SAP programme. The role exists to own the billing layer of order to cash, where configuration defects translate directly into unbilled revenue, incorrect customer invoices and delayed period close.
You carry delivery risk for the process area and are expected to enter a drifting workstream, establish an evidenced position and reset the plan. You remain hands-on: the most difficult design and configuration work is yours, as is the review gate before work leaves the process area. Quality, defect trend and release readiness sit with you, together with the AI standard and the technical development of the Managers you lead.
Technical development is your responsibility, hold the client leadership relationship for the process area, and remain close enough to the detail to test the evidence behind a status report.
Roles & Responsibilities:
Scope & Decision Rights: Hold design authority for the process area and remain hands-on. The hardest design calls are taken by you personally, and you prove the pattern before the team builds to it. You approve decisions that carry downstream cost, hold the review gate on work leaving the process area, set the quality gates Managers deliver to, and own the delivery risk position reported to programme governance.
Billing Document Design: Configure and own billing document types, billing plans (periodic and milestone), copy control from delivery and order, invoice split logic, cancellation and reversal behaviour, and intercompany billing flows.
Revenue Account Determination: Own revenue account determination and the posting interface into Finance resolve account determination failures and billing documents stuck in accounting rather than routing them to Finance unresolved.
Billing Due List & Period Close: Keep the billing due list clean: analyse and clear blocked, incomplete and failed billing documents, and make sure the billing run completes inside the period-close window.
Output & e-Invoicing: Configure invoice output determination and form output, and support statutory e-invoicing and e-document requirements in the countries in scope.
Integration & Dependencies: Manage the dependencies into Finance for revenue posting and into Order Management and Pricing upstream. Credit Management, Collections and Cash Application sit with the Finance tower coordinate on them, do not design them.
Solution & Delivery Governance: Own solution design and delivery quality across the process area: set the design standards, approve decisions carrying downstream cost, and hold accountability for delivery risk, defect trend and release readiness across workstreams.
Delivery Recovery Leadership: Lead recovery of stressed workstreams, including a billing run failing or splitting incorrectly in the period-close window: establish an evidenced position, re-plan, reallocate, remove the structural cause and report a defensible trajectory to programme leadership.
AI-Native Delivery Standards & Joule Governance: Define how AI is applied across the process area, including AI-assisted billing configuration analysis, close-cycle exception triage and automated regression scenario generation govern the accelerator library, set validation and IP controls, and report productivity and quality outcomes. Set the standard for SAP Joule for Consultants use and the governance of its grounding content, and decide where a Joule agent is warranted against standard configuration, holding the specification and acceptance standard with the AI and AIDLC tower.
Mentoring & Capability Building: Develop the Managers who lead the workstreams: run design reviews as teaching, pair on configuration they have not done before, and codify the resulting patterns so the capability outlives the individual. Set the technical standard across the process area and own succession for its scarce skills.
Executive & Client Engagement: Represent the process area in client leadership and programme governance forums, defend design decisions, and negotiate scope and timeline against capacity.
Professional & Technical Skills:
Must-Have Skills
SD Billing Configuration: Design authority over billing document types, billing plans, copy control, invoice split criteria, cancellation and intercompany billing in SAP S/4HANA or ECC.
Revenue Account Determination: Expert-level expertise in revenue account determination and the SD to FI posting interface, including diagnosing accounting document failures.
Pricing Interaction: Comprehensive command of the condition technique as it affects billing values, taxes and rebate-relevant conditions.
Output Management: Extensive experience configuring billing output, form determination and output-related error handling in S/4HANA Output Management or NAST.
Period Close Delivery: Extensive experience supporting or owning billing activity through month-end and year-end close under time pressure.
Master Data Dependencies: Comprehensive command of customer, material and pricing master data as it drives billing correctness.
Hands-On Technical Depth: Current, hands-on command of the primary skill. This is a working design authority role, not an oversight role: the hardest configuration in the process area is expected to be done by the post-holder.
Hands-On Currency: Hands-on configuration or design-level build work on the primary skill within the last 24 months. Advisory, pre-sales, governance or oversight-only experience during that period does not satisfy this requirement. Where recent experience is advisory, a technical validation forms part of selection.
Technical Mentoring & Capability Building: Demonstrated development of Managers and senior engineers through design review, pairing and codified patterns, evidenced by capability the team retained rather than output the individual delivered.
AI-Enabled Delivery Leadership: Demonstrated definition of AI standards across an SAP delivery team or tower, including validation controls, accelerator ownership and measured productivity outcomes.
Evidence of AI Adoption: Demonstrable record of raising delivery productivity through AI or equivalent means: AI assistant adoption, delivery accelerators, reference architectures or codified playbooks built for reuse across teams, with measurable effect on throughput or quality.
Multi-Workstream Delivery & Recovery: Demonstrated leadership across multiple SAP workstreams, including at least one engagement behind plan or under quality pressure, with personal accountability for the recovery.
Executive Stakeholder Management: Credible in client leadership forums, with demonstrated capability to make and defend design and delivery decisions under incomplete information and commercial pressure.
Good to Have Skills
SAP Revenue Accounting and Reporting (RAR) or IFRS 15 revenue scenarios
Country-specific e-invoicing localisation and the SAP Document and Reporting Compliance framework
SAP BRIM or Convergent Invoicing exposure
Clean Core extensibility for billing documents on S/4HANA

Minimum 15 years of experience on the primary skill, as specified in the approved demand record.
Hands-on configuration or design-level build work on the primary skill within the last 24 months.

Evidenced record of setting AI-enabled or equivalent delivery productivity standards for a team or tower.
