When PBRs Are Required—And How to Get One Approved
Estimated Read Time: 8 minutes
If you’re working with the federal government on cost-reimbursable or Time & Materials (T&M) contracts, one question should come up before your first invoice is sent: Do I need a Provisional Billing Rate (PBR)?
For many small and mid-sized government contractors, the answer is yes.
This article Part 2 in our 10-part series explains when a PBR is required, what triggers the requirement under FAR 42.704, and how to prepare a strong submission to the Defense Contract Audit Agency (DCAA).
What Is a PBR and Who Needs One?
A Provisional Billing Rate is a temporary, government-approved indirect cost rate that allows contractors to recover costs like fringe, overhead, and G&A as work is performed rather than waiting until the end of the fiscal year for a final audited rate.
If you’re billing under cost-type or T&M contracts, you’ll likely need to submit a PBR proposal to the DCAA. These rates are required by the Federal Acquisition Regulation (FAR) 42.704, which governs how the government ensures interim reimbursement of indirect costs.
If your contracts are strictly fixed-price, you may not need a PBR. But once your business begins working on flexibly priced contracts, a PBR becomes essential.
Why Does the Government Require This?
The federal government reimburses contractors for allowable indirect costs but only if those charges are based on reasonable, supportable rates. A PBR acts as a safeguard to ensure that contractors are billing within fair, agreed-upon limits while allowing them to maintain healthy cash flow.
The DCAA or contracting officer uses a mix of prior audits, recent incurred cost data, and industry norms to review submitted rates. Contractors may voluntarily submit a billing rate proposal to speed this process along and avoid assigned rates that may not reflect their true cost structure.
The goal is simple: help you get paid accurately without overbilling the government or underfunding your operations.
How to Get a PBR Approved
To apply for a PBR, contractors submit a proposal to the DCAA that typically includes:
- Projected indirect cost pools (fringe, overhead, and G&A)
- The cost base used to calculate each rate (e.g., direct labor or total cost input)
- Supporting documentation that shows how the rates were developed
Once submitted, DCAA reviews the proposal for accuracy, consistency, and reasonableness. If accepted, the provisional rates are approved and can be used to bill the government monthly.
In some cases, the contracting officer or auditor may establish the PBR without a proposal particularly if the contract’s value is small or if past cost data is already available. These rates are typically based on previous year experience, adjusted for nonrecurring or unallowable costs.
If you’re unsure whether your business should submit a proposal or wait for the government to assign a rate, early communication with DCAA or your contracting officer can help avoid delays.
What Happens If You Don’t Submit?
Contractors that don’t submit a required PBR may face:
- Invoice rejections or partial payments
- Compliance issues during DCAA audits
- Delays in cash flow that affect payroll, vendor payments, and growth plans
For growing GovCons, these challenges can escalate quickly. In fact, many contractors only realize the importance of PBRs when their first indirect cost charges are denied.
