ICS preparation takes40 to 120 hoursin a legacy ERP firm.It takes zero hours in a compliant one.
Interim Cost Submissions (ICS)
"ICS preparation time is a direct measure of compliance architecture quality. A firm that requires 40 to 120 hours to prepare an ICS package is demonstrating that its systems did not maintain cost data in ICS-ready format throughout the year. A contract-native system requires zero hours because the ICS schedules are continuously generated from live operational data."
Paper 6 covers ICS purpose and regulatory requirements, the full required schedule structure (Schedules A through O), rate forecasting mechanics, pool/base reconciliation, daily ICS readiness, and the six most common ICS findings — and how each is prevented by architecture rather than annual effort.
Paper 6 makes a distinction that most GovCon firms miss: rate forecasting is not a financial planning exercise. It is a compliance early warning system. A firm that forecasts its year-end indirect rates monthly using live pool and base data can identify a 15% provisional rate variance in March and revise its PBR agreement in April. A firm that discovers the same variance at ICS submission in June has no options left — only retroactive billing adjustments and a billing system adequacy question from DCAA about why the variance was not identified and addressed earlier.

The Argument
Why Rate Forecasting Is a Compliance Early Warning System
Paper 6 makes a distinction that most GovCon firms miss: rate forecasting is not a financial planning exercise. It is a compliance early warning system. A firm that forecasts its year-end indirect rates monthly using live pool and base data can identify a 15% provisional rate variance in March and revise its PBR agreement in April. A firm that discovers the same variance at ICS submission in June has no options left — only retroactive billing adjustments and a billing system adequacy question from DCAA about why the variance was not identified and addressed earlier. ""Rate forecasting is not a financial planning exercise. It is a compliance early warning system. The difference between identifying a 15% PBR variance in March and discovering it at ICS submission in June is the difference between a proactive revision and a retroactive correction.""
The False Claims Act Connection
The ICS certification requirement adds a legal dimension that pure accounting submissions do not carry. When a company officer signs the ICS certification, they are certifying that all costs are allowable, allocable, and reasonable. If the submission contains costs that the certifier knew or should have known were unallowable, the certification may create False Claims Act exposure beyond the DCAA finding. This is why the unallowable cost segregation architecture in Paper 4 is not just a rate accuracy mechanism — it is a certification integrity mechanism.
One question determines ICS readiness: if DCAA requested your ICS today — with no advance notice and no preparation time — could you submit a complete, compliant, fully reconciled package? In a contract-native system, the answer is always yes. In a legacy ERP system, the answer is: not without 40 to 120 hours of work. The preparation time is the finding.
The Architecture of Choice
Side-by-side comparison of structural assumptions and operational outcomes.
ICS as Annual Preparation Project (Legacy ERP)
Schedule B data extracted from G/L — weeks before deadline
Pool cost detail must be extracted, formatted, and reconciled from the general ledger. Chart-of-accounts may not map directly to ICS schedule structure. Manual reformatting required.
Schedule C reconciled from timekeeping, payroll, and G/L separately
Direct costs per contract assembled from three systems with different transaction records. Reconciliation differences must be identified and resolved before Schedule C can be certified.
Unallowable cost review performed at submission time
Period-end review of costs to identify and remove unallowable items from pools. Corrections required retroactively. Schedule H populated from this review — not from continuous tracking.
Rate calculations performed at submission from assembled data
Schedule D rates calculated from the reconciled pool and base totals assembled during the preparation project. Rate has not been visible during the year. Variances discovered at submission.
ICS as Reporting Event (xpdOffice)
Schedule B continuously maintained from live cost entries
Every cost entry posts to the correct pool in ICS format. Schedule B is always current. No extraction, no reformatting, no reconciliation effort required at year-end.
Schedule C current by contract from every posted transaction
Direct costs organized by contract and CLIN as they are posted. Schedule C is a live view, not a year-end assembly. Reconciliation to the general ledger is a system query.
Unallowable costs segregated at entry — Schedule H always current
Costs flagged as unallowable at the point of entry are continuously tracked in Schedule H format. No year-end unallowable cost review because unallowable costs never entered pools.
Rate calculations current to last write event all year
Schedule D rates updated on every cost entry. Rate variance from provisional rates visible daily. Variances identified and addressed months before the ICS deadline.
Strategic Insight
""Rate forecasting is not a financial planning exercise. It is a compliance early warning system. The difference between identifying a 15% PBR variance in March and discovering it at ICS submission in June is the difference between a proactive revision and a retroactive correction.""
