What is Consulting Costs FAR 31.205-33?

Definition

Consulting Costs FAR 31.205-33 addresses the allowability of costs associated with professional and consultant services under U.S. federal contracts. Federal Acquisition Regulation (FAR) 31.205-33 establishes criteria for determining whether consultant costs are allowable, including considerations related to the nature of the services, business purpose, documentation, and relationship to contract performance.

For government contractors, the rule is important because a consulting expenditure may be recorded in the accounting system but still require specific support to demonstrate that it is an allowable contract cost. Contractors therefore need documentation that connects the engagement, services performed, compensation, and business purpose.

What FAR 31.205-33 Covers

FAR 31.205-33 applies to costs associated with professional and consultant services obtained by contractors. The evaluation focuses on whether the services have a reasonable business purpose and whether the associated costs satisfy applicable federal cost principles.

Contractors should maintain records that explain why the consultant was engaged, what services were provided, the agreed compensation, and how the work relates to the contractor's operations or contract responsibilities.

  • Nature of services: Documentation should identify the specific professional or consulting work performed.
  • Business purpose: Records should establish why the contractor required the services.
  • Compensation: Agreements and invoices should support the amounts paid or accrued.
  • Contract relationship: Where applicable, records should demonstrate the connection between the services and contract performance.
  • Supporting evidence: Engagement agreements, invoices, work products, correspondence, and approval records can provide evidence for the accounting treatment.

Documentation and Cost Allowability

Documentation is central to evaluating consulting costs. A contractor should be able to explain the identity of the consultant, scope of work, dates of service, compensation arrangements, and evidence that the services were actually performed.

The accounting record should also use appropriate classifications and retain supporting documents. This allows finance teams to distinguish consulting expenditures from other operating or contract costs and provides a clearer audit trail.

Consulting arrangements can involve multiple projects or contracts, so contractors should establish a consistent method for identifying the benefiting activity. This supports appropriate cost allocation and more reliable contract financial reporting.

Consulting Costs and Procurement Controls

When a contractor engages a consultant, the procurement workflow can begin with a requisition describing the business requirement and expected services. Approval and sourcing records should establish the basis for selecting the consultant and authorizing the expenditure.

A purchase order can document approved services, commercial terms, pricing, and authorization before work begins. Broader procurement controls can connect requisitions, sourcing, approvals, supplier records, and spend visibility so that consulting engagements are consistently documented.

These controls are particularly useful when consulting services involve recurring engagements, multiple contracts, or significant expenditures that require clear internal authorization.

ERP and Accounting Treatment

An ERP can provide a central structure for recording consultant invoices, contract references, project information, approvals, and general ledger classifications. Contractors evaluating system architecture may review How to Choose the Right ERP Consulting Firm when considering ERP implementation, integration, migration, or finance-workflow extensions.

For organizations using Oracle-based environments, oracle ERP integration can connect consulting-related purchasing and accounting information with broader financial workflows. The objective is to maintain consistent data between procurement, project accounting, accounts payable, and reporting systems.

ERP Consulting provides a related framework for understanding how specialists help organizations configure, integrate, and improve ERP environments that support finance and business processes.

Specialized ERP Consulting Services can also address implementation, integration, data migration, and finance workflow requirements when organizations need their ERP environment to support government-contracting processes.

Accounting and Audit Considerations

Consulting costs should be recorded consistently with the contractor's established accounting practices and applicable federal cost principles. Finance teams should retain the underlying agreement, invoice, approval evidence, description of services, and other documentation necessary to explain the transaction.

Consulting Firm Accounting provides a related accounting perspective because consulting organizations themselves must classify revenue, expenses, labor, and project-related transactions accurately. For a government contractor purchasing consulting services, however, the primary focus remains on documenting and appropriately accounting for the contractor's expenditure.

During an audit or cost review, a well-organized record can help demonstrate what was purchased, why it was needed, who performed the work, how much was paid, and which accounting or contract activity received the cost.

Best Practices for Managing Consultant Costs

  • Define the scope: Document the services, deliverables, period of performance, and expected business purpose before engagement.
  • Maintain agreements: Retain executed consulting agreements and amendments with the related purchasing records.
  • Connect invoices to work: Match invoices with supporting evidence such as deliverables, reports, time records, or other appropriate documentation.
  • Apply consistent coding: Use the appropriate contract, project, task, cost element, and general ledger classifications.
  • Preserve approvals: Maintain evidence showing that the engagement and related expenditures received the required authorization.

These practices help contractors maintain a transparent cost trail from the initial consulting requirement through procurement, service delivery, invoicing, accounting, and financial reporting.

Summary

Consulting Costs FAR 31.205-33 provides the federal contracting framework for evaluating costs associated with professional and consultant services. Contractors should focus on the nature and business purpose of the services, appropriate compensation, supporting documentation, procurement authorization, and consistent accounting treatment. Strong records help connect consulting expenditures to legitimate business activities and support reliable contract cost reporting.
