Most common billing mistakes contractors make
By Marcelle Green
- The clerical person responsible for processing vouchers doesn’t usually care whether the contractor gets paid or not. The clerk's goal is to process the paperwork if it’s correct, and kick it back if it isn’t.
- The clerk processing those bills isn’t very knowledgeable beyond the narrow scope of his or her job. The clerk won’t think, “Oh, the bill says this, but it must mean that.” A contractor who designates a cost incorrectly will have the invoice rejected, not corrected.
- Using the wrong Department of Defense Activity Address Code (DoDACC). This six-digit number identifies a unit, activity, or organization that has the authority to requisition and/or receive material. When a bill is submitted using the wrong code, it goes to the wrong office, and the DCAA office will reject the bill. Double-check with the contracting officer that the correct code is being used before submitting the first bill.
- Submitting vouchers out of numerical sequence.
- Billing indirect costs based on provisional billing rates that have not had prior DCAA approval.
- Using outdated billing rates, for example, applying last year's rates to this year's costs.
- Failing to submit a request, along with supporting documentation, for new interim billing rates or for temporary adjustment rates. Final billing rates are used after the DCAA completes its audit of your incurred cost submission and there has been a formal rate agreement.
- Mathematical errors, such as: last cumulative plus new charges do not equal new cumulative; backing into the total funded amount rather than showing the actual incurred cost and subtracting the amount in excess of the funding limit; or rate times base does not equal the amount shown on the public voucher.
- Billing costs in excess of the funded amount of the contract.
- Billing fee in excess of contractual limitations (some contracts cap fee at 85 percent until final billing).
- Not billing by Contract Line Item Numbers/Sub Line Item Numbers (CLIN/SLIN) when the contract is costed and funded by CLIN/SLIN.
- Submitting incomplete, incorrect, or inadequate detail to support the public voucher.
