Procure-to-Pay & Order-to-Cash Process Design

Objective

Design practical Procure-to-Pay and Order-to-Cash operating models that reduce ambiguity between procurement, AP, AR, treasury/cash, and controllers — while protecting invoice quality, billing accuracy, and period integrity.

Business context (generic scenario)

Finance needs one shared language for how supplier invoices and customer invoices move from intake to settlement, including what happens when documents fail match, approvals stall, or cash cannot be applied cleanly.

• AP volume includes PO and non-PO invoices with different risk profiles
• AR needs consistent billing, credit memo, and receipt application patterns
• Month-end suffers when exceptions are informal and undocumented
• GL foundation from Case Study 01 is assumed as the CoA / ledger baseline

Scope

• Supplier invoice intake → validation → approval → payment readiness
• Match rules, holds, tolerances, and exception routing
• Customer invoicing → adjustments → receipt application
• Credit memos, disputes, and unapplied cash handling patterns
• Cross-process dependencies with GL, cash management, and close calendar
• UAT-style scenario list for happy path and exception path

P2P design highlights

Happy path

1. Supplier / site readiness and invoice intake channel defined
2. Invoice validation against PO / receipt / amount rules where applicable
3. Approval routing by amount, account, or business unit policy
4. Hold release criteria documented before payment batching
5. Payment readiness checks and GL accounting confirmation

Exception path

• Price / quantity / receipt mismatches with named resolvers
• Missing tax or distribution details with reject vs hold rules
• Duplicate invoice detection and investigation steps
• Escalation timing when approvals exceed SLA

O2C design highlights

Happy path

1. Customer / bill-to readiness and invoice generation standards
2. Invoice distribution and dispute intake channel
3. Receipt creation and application rules (auto vs manual)
4. Credit memo / adjustment governance
5. Unapplied and on-account cash aging review

Exception path

• Short pays and partial applications with follow-up owners
• Misapplied cash correction steps
• Billing disputes that must block aggressive collection actions
• Period-end cutover rules for invoices and receipts

Approach

1. 01
   Map current language Document how teams describe invoice, hold, approval, and cash steps today.
2. 02
   Design happy path first Lock clean flows before branching into exceptions.
3. 03
   Build exception matrix Reason, owner, SLA, and period impact for each major exception.
4. 04
   Align to CoA / ledger Confirm distributions and accounting touchpoints match foundation blueprint.
5. 05
   Write UAT scripts Convert process maps into testable scenarios finance can execute.

Controls & risks

• Approval thresholds and segregation of duties called out explicitly
• Hold reasons standardized so analytics and aging stay meaningful
• Cash application rules prevent silent on-account buildup
• Risk: shadow spreadsheets outside Fusion — mitigated by process ownership and exception SLAs
• Risk: period integrity broken by late AP/AR activity — mitigated by close cutover rules

Deliverables

Outcomes

• Two complete operational designs that show end-to-end finance process thinking
• Exception handling that looks implementation-ready, not ideal-path only
• Clear bridge from transactional flows into period close and reporting quality
