GovCon accounting + DCAA + on-prem AI
AI for Government Contractor ERP Under DCAA Scrutiny
Short answer
Government contractors add AI to a DCAA-compliant accounting system, typically Deltek Costpoint or a GovCon-configured SAP, Oracle, Infor, or Dynamics instance, by grounding a private model in project ledger, timekeeping, and indirect rate pool data to draft incurred cost narratives, flag potential FAR Part 31 unallowable costs, and assemble audit support packages faster. Every draft is reviewed by finance staff before it goes into a submission, and the model runs on infrastructure the contractor controls so CUI-adjacent cost and contract data never leaves the accounting system's existing security boundary.

A DCAA-compliant accounting system already runs on discipline: labor charged to the correct contract line, indirect costs pooled and allocated consistently, and every adjustment traceable to a reason and an approver. That discipline is exactly what makes the close and the annual incurred cost submission so labor-intensive. A controller or CFO ends up writing the same category of variance narrative every month, chasing down the same category of timesheet correction, and assembling the same category of supporting documentation whenever DCAA asks a follow-up question.
The indirect rate pools are usually the sharpest pain point. Fringe, overhead, and G&A rates drift from the provisional rate through the year, and explaining why, in language an auditor will accept, takes a cost accountant real time every close cycle. The underlying data, labor distribution, project ledger transactions, and pool base changes, already sits in the ERP; the bottleneck is turning that data into a defensible written narrative on a deadline.
Incurred cost submission (ICE) season compounds this. Pulling final indirect rates, reconciling them to the general ledger, and assembling the supporting schedules is weeks of work that is largely mechanical reconciliation punctuated by judgment calls on a handful of genuinely ambiguous cost items. A model grounded in the project ledger and GL can do the mechanical reconciliation and flag the items that need a human judgment call, rather than the finance team doing every step by hand.
Because the data involved is contract cost data, often tied to CUI and DFARS-covered information, most contractors want this AI layer running inside the same accounting-system security boundary DCAA has already reviewed, not routed through a public cloud API. A private model served on infrastructure the contractor controls keeps the audit trail, and the underlying cost data, inside a boundary that does not need to be explained fresh to every auditor.
What usually gets in the way
The problems we hear most from cfo teams running Deltek Costpoint.
Indirect rate variance narratives are written from scratch every close
Explaining why fringe, overhead, or G&A drifted from the provisional rate requires pulling pool and base detail from the ledger and writing it up in auditor-acceptable language, every month, largely by hand.
Incurred cost submission prep takes weeks
Reconciling final indirect rates to the general ledger and assembling ICE schedules is mostly mechanical work that still consumes a cost accountant's time for weeks each year.
Timesheet corrections draw audit scrutiny
DCAA auditors look closely at the volume and pattern of labor corrections; today, spotting an unusual correction pattern before an auditor does is a manual review exercise.
Unallowable cost flags depend on one or two people's memory
Recognizing a FAR 31.205 unallowable cost category as it is coded, rather than after an auditor questions it, relies on the reviewer remembering the rule, not on a system check.
Audit document requests eat controller time on short notice
A DCAA request for supporting documentation on a specific transaction or period means manually searching the ERP and file shares for the right invoice, timesheet, or approval trail.
Where AI earns its place in Deltek Costpoint
Each use case names the ERP objects it reads or writes, so your ERP team can judge the integration effort before anyone commits budget.
Indirect rate variance narrative drafting
Pulls pool and base detail for fringe, overhead, and G&A from the project ledger and drafts a first-pass variance narrative comparing actual to provisional rates, for the cost accountant to edit and finalize.
Touches: Project ledger, indirect rate pool and base tables, GL account detail
Outcome: Cuts the drafting time for routine monthly variance commentary from hours to a review-and-edit pass, freeing time for the pools with a genuine story behind them.
Unallowable cost flagging
Screens newly posted transactions against FAR Part 31.205 unallowable cost categories (entertainment, alcohol, certain advertising, fines) and flags matches for the cost accountant to confirm the coding.
Touches: GL transaction detail, expense category and account mapping tables
Outcome: Surfaces potential miscoding at the time of posting rather than at the time of an auditor's sample test.
Timesheet anomaly detection
Reviews labor distribution and correction history for unusual patterns, such as a spike in corrections to a single contract or charge code, and summarizes them for the timekeeping administrator to review.
Touches: Labor distribution, timesheet correction/audit log tables
Outcome: Gives the timekeeping team an early view of the same patterns a DCAA floorcheck or audit would look for.
Incurred cost submission (ICE) schedule assist
Reconciles final indirect rates to the general ledger and assembles the standard ICE schedules, flagging any reconciling items that need a manual explanation rather than a mechanical fix.
Touches: Project ledger, GL, indirect rate calculation tables
Outcome: Turns weeks of mechanical reconciliation into a review pass over the reconciling items that actually need judgment.
DCAA audit document retrieval
Answers a specific document or transaction request (a timesheet, an approval, an invoice tied to a contract line) by pulling the record and its approval trail directly from the ERP on request.
Touches: Project ledger, AP/invoice records, approval workflow logs
Outcome: Cuts the time from an auditor's request to a produced document, which matters directly to how an audit visit is perceived.
Forward pricing rate proposal support
Assembles historical rate and cost trend data the estimating team needs to support a forward pricing rate proposal, pulling consistent numbers from the same ledger data used in the actual rate calculations.
Touches: Project ledger, indirect rate history, budget and forecast tables
Outcome: Keeps forward pricing assumptions traceable to the same source data as the actual accounting, reducing the risk of a mismatch an auditor later flags.
Contract-level profitability question answering
Lets a program manager or the CFO ask a direct question about a contract's burn rate, funding remaining, or margin trend and get an answer grounded in the project ledger, with the underlying transactions shown.
Touches: Project ledger, contract funding and billing tables
Outcome: Replaces a request to the finance team for a custom report with a self-service answer the requester can still verify against the source records.
Reference architecture
The AI layer reads the accounting system's project ledger, labor distribution, and indirect rate data through a read-only connector, drafts narratives and flags exceptions through narrow agents, and never posts a journal entry, timesheet correction, or rate change without a named finance approver.
- 1
ERP connectors
Read-only access to the project accounting system, for Costpoint this typically means its reporting APIs or a replicated database view; for SAP, Oracle EBS, Infor LN, or Dynamics 365 configured for government contracting, the equivalent OData, interface table, or BOD read path.
- 2
Data / semantic layer
Maps raw ledger and pool/base tables into the vocabulary a cost accountant already uses, indirect rate, pool base, unallowable cost category, so questions can be asked in plain accounting language.
- 3
Model serving
An open-weight model served on infrastructure the contractor controls, sized for the finance team's concurrent usage rather than enterprise-wide scale.
- 4
Retrieval and agents
Retrieval-augmented generation for narrative drafting and document lookup, plus narrow agents for unallowable cost screening and ICE reconciliation, none of which write back to the ledger autonomously.
- 5
Governance and audit
Every draft narrative, flagged transaction, and retrieved document is logged with the requesting user, providing its own audit trail for how a submission or answer was produced.
Integration notes for your ERP team
- Deltek Costpoint: reporting and integration APIs, or a replicated read-only database view, give access to project ledger, labor distribution, and indirect rate pool/base tables without touching the transactional posting path.
- SAP S/4HANA or ECC configured for GovCon: OData services and CDS views over project systems (PS) and controlling (CO) data provide the equivalent project ledger and cost pool detail.
- Oracle EBS: project accounting and general ledger interface tables and open APIs, read through a dedicated integration responsibility scoped to reporting access only.
- Infor LN: project and BOD-based read access to cost and billing sessions for contractors running LN's project/contract accounting configuration.
- Timekeeping data, whether native to the ERP or a separate DCAA-compliant timekeeping system, is joined into the same semantic layer so labor distribution questions have a single source of truth.
- No AI-drafted narrative, flagged transaction, or ICE schedule is treated as final until a named cost accountant or controller signs off inside the normal review workflow.
- Access is scoped per user role exactly as the ERP already scopes it, so a program-level user cannot query indirect rate pool detail they could not already see.
Deployment options
Air-gapped on-prem
Contractors handling CUI or working inside a CMMC-scoped enclave
The model and connector run entirely inside the enclave that already holds the accounting system, with no outbound path, so the AI layer does not expand the CMMC assessment boundary.
Private / sovereign cloud
Contractors without CUI-level restrictions who still want data to stay off public model APIs
A single-tenant deployment under the contractor's control, connected privately to the accounting system, suitable when the primary concern is data control rather than a formal enclave requirement.
Hybrid
Larger contractors with mixed commercial and government work
Government-contract cost data and the narrative/ICE workflows stay on the air-gapped instance, while broader finance question-answering for commercial business units can run on a lighter private cloud footprint.
Compliance and data control
How the architecture supports your obligations. Certification and accountability stay with your organisation; the design keeps the evidence straightforward.
DCAA business system adequacy (DFARS 252.242-7006)
The AI layer changes nothing about how transactions are approved or posted; it drafts and flags for human review, so the accounting system's existing approved business system controls remain intact.
FAR Part 31 cost principles
Unallowable cost screening is built from the same FAR 31.205 categories the cost accountants already apply, presented as a flag for confirmation, not an automatic recode.
DFARS 252.204-7012 / NIST SP 800-171
Access, logging, and encryption controls for the AI layer are built to the same control set already implemented for the accounting system holding covered defense information.
CMMC 2.0
Where the contractor's environment is scoped for CMMC Level 2, the AI layer sits inside the same enclave boundary rather than introducing a new, separately assessed system.
Where Netray fits
ERPray
Grounded question-answering over project ledger and rate data works the same way whether the underlying system is Costpoint, SAP, Oracle EBS, Infor LN, or Dynamics 365, which matters for contractors that run more than one system across business units.
Custom build
Indirect rate narrative drafting and ICE schedule assembly are specific enough to GovCon accounting that most contractors need a purpose-built agent rather than a generic reporting tool.

Questions to ask any vendor, including us
A short list that separates real Deltek Costpoint AI work from a chatbot demo.
- Does the AI layer ever post a journal entry, rate change, or timesheet correction, or does every action require a named finance approver?
- Where does the model run, and does any project cost or contract data leave our accounting system's existing security boundary?
- How does the unallowable cost screen stay current with FAR Part 31 changes, and who is responsible for updating the rule set?
- Can the finance team see exactly which ledger transactions a drafted narrative or flag is based on?
- Does this expand our CMMC assessment boundary, and how is that determined?
- What is the actual time saved on a real ICE submission, not a hypothetical, and can we see it during the pilot?
- How is access scoped so a user cannot see indirect rate or contract data beyond their existing ERP permissions?
- Who owns the audit trail of AI-drafted content if DCAA asks how a submission number was produced?
Frequently asked questions
Will DCAA have a problem with AI-drafted variance narratives?
The narrative is a draft that a cost accountant reviews, edits, and signs off on before it goes into any submission, so the accounting system's existing review and approval controls are unchanged. What matters to DCAA is that the numbers reconcile to the ledger and that a qualified person stands behind the final language, both of which this workflow preserves.
Does this replace our cost accountants?
No, it removes the mechanical reconciliation and first-draft writing so cost accountants spend their time on judgment calls, unusual variances, and reviewing the AI's output, rather than on the repetitive parts of every close.
Can this run without sending our contract cost data to a public cloud AI service?
Yes, that is the default design for GovCon deployments: an open-weight model served on infrastructure the contractor controls, connected to the accounting system through a read-only integration, with no data sent to a third-party model API.
How does the unallowable cost screen know FAR 31.205 categories?
It is configured with the same unallowable cost category rules a cost accountant already applies, and it flags matches for human confirmation rather than automatically recoding anything, since the final judgment on borderline cases stays with the accountant.
What ERPs does this work with besides Costpoint?
Any accounting system configured for government contract cost accounting works, including SAP S/4HANA or ECC with project systems, Oracle EBS project accounting, Infor LN project/contract accounting, and Dynamics 365, since the underlying pattern is project ledger and indirect rate data, not a specific vendor.
How long before we see value in a pilot?
Most contractors see a measurable drop in narrative drafting time within the first pilot cycle, typically the first full month-end close after the connector is live, since that is a recurring task rather than an annual one like ICE.
Does this help with forward pricing rate proposals too?
Yes, the same ledger and rate history data used for actual accounting can support a forward pricing rate proposal, which keeps the proposal's assumptions traceable to the same source data the actual rates are built from.
