What a TSA Review Covers
A comprehensive review considers both contractual terms and actual service delivery. The reviewer compares the TSA's documented obligations with operating evidence, financial records, service reports, and transition milestones.
- Service scope: Confirm that services being delivered match the agreed descriptions, responsibilities, and boundaries.
- Service performance: Assess service levels, response times, deliverables, reporting, and unresolved operational matters.
- Financial terms: Review charges, allocation methodologies, invoices, credits, adjustments, and supporting calculations.
- Governance: Evaluate ownership, approvals, escalation procedures, meeting structures, and decision rights.
- Transition readiness: Determine whether replacement capabilities and exit requirements are progressing according to plan.
The glossary concept Contract Review is closely related because it focuses on examining contractual terms, obligations, and provisions. In a TSA context, that review is applied specifically to temporary services and the transition requirements surrounding them.
Operational and Financial Review
TSA Review should connect operational evidence with financial information. For example, finance teams can compare contracted service volumes with actual activity, verify invoice calculations, reconcile charges to approved pricing structures, and investigate differences between expected and billed amounts.
Accounting processes should also be reviewed for accurate classification, reconciliation, reporting, and audit support. The chart of accounts may need to be examined where TSA costs are recorded across entities, departments, cost centers, or reporting dimensions. This helps ensure that transition-related expenditure remains visible and appropriately reported.
A P L Review can provide an additional perspective by examining how TSA-related income and expenses affect the profit and loss statement. Reviewing these impacts helps management understand whether temporary service arrangements are being reflected consistently in financial reporting and performance analysis.
Procurement, Tax, and Transaction Controls
TSA activities may include procurement and supplier processes that continue through shared systems or operating teams. A TSA Review should therefore examine requisitions, approvals, sourcing decisions, procurement controls, and the use of a purchase order where applicable. The objective is to confirm that transactions remain properly authorized and traceable during the transition.
Tax requirements can also affect TSA charges and transactions. Where services involve different jurisdictions, the review may assess sales tax treatment, applicable exemptions, nexus considerations, VAT or GST requirements, and the accuracy of tax calculations. These checks are particularly relevant when services cross legal entities or geographic boundaries.
Transaction-level coding is another useful review area. Coding Review provides a related framework for examining whether financial transactions are assigned to appropriate accounts, dimensions, entities, or categories. Within a TSA, this can support consistent reporting and reconciliation across temporary service arrangements.
Auditability and Service Evidence
A strong TSA Review relies on evidence that demonstrates what services were performed, who performed them, when they occurred, and how they were approved or charged. Relevant evidence may include service reports, invoices, approval records, issue logs, access records, process documentation, meeting minutes, and transition status reports.
Audit Trails are particularly useful for vendor-management activities because they can record actions taken by humans or AI, creating transparency around each step and supporting subsequent review. Maintaining reliable activity records helps connect operational events with approvals, decisions, and service outcomes.
Review Timing and Decision Use
TSA Review can serve different purposes depending on when it is performed. Before signing, it can validate service scope and commercial assumptions. During execution, it can monitor performance, spending, dependencies, and changes to requirements. Near exit, it can assess whether replacement capabilities are ready and whether outstanding obligations have been resolved.
The review should distinguish between contractual compliance and operational readiness. A service can technically comply with its stated terms while the receiving organization may still need additional systems, staffing, documentation, or controls before assuming responsibility. Separating these perspectives produces a more useful assessment for management.
Best Practices for TSA Review
- Review against the signed agreement: Use the approved TSA, schedules, service descriptions, pricing terms, and amendments as the primary reference points.
- Use evidence-based testing: Validate important conclusions against invoices, reports, approvals, operational records, and transition documentation.
- Connect financial and operational data: Reconcile service performance with charges, transaction volumes, and accounting records.
- Track exceptions clearly: Record open issues, responsible owners, required actions, target dates, and resolution status.
- Assess exit readiness: Confirm that replacement systems, processes, people, controls, and documentation are sufficiently prepared before service termination.
- Maintain review continuity: Use consistent criteria across recurring reviews so changes in performance and readiness can be identified over time.
Summary
TSA Review provides a structured way to assess whether transition services remain contractually aligned, operationally effective, financially accurate, and ready for eventual independence. By examining service delivery, financial records, procurement, tax, accounting, controls, audit evidence, and exit readiness, organizations can make better-informed decisions throughout a business separation while strengthening financial reporting and operational governance.
