AR Automation for Deltek Costpoint

AR automation for Deltek Costpoint means adding a layer above Costpoint that runs collections and cash application while Costpoint stays the system of record for your ledger and contract billing. Monk is an AI-native invoice-to-cash platform that handles invoice delivery, portal submission, collections and cash application as one system, built to sit above an ERP rather than replace it.

Government contractors on Costpoint usually have an accurate, DCAA-ready ledger, but much of what delays payment never shows up in it. An invoice can sit in an agency system such as the DoD's Wide Area Workflow for weeks because a required attachment is missing, while Costpoint shows it as an open invoice aging normally. This guide explains how to map Costpoint data for an automation layer, where Costpoint integrations usually go wrong, how to test GL effects before go-live and what to ask a vendor to show you.

Can you automate AR without replacing Costpoint?

Yes, as long as the automation layer reads from Costpoint and writes back only through controlled steps.

The layer reads invoices and payments from Costpoint and does the follow-up and matching outside it. Any write-back is proposed first and posts only after someone approves it. In DCAA-auditable environments, the layer also needs to log every action in a way that can't be edited afterward. For a broader look at how AR platforms should connect to an ERP, see our guide to ERP and billing integration for AR.

Which Costpoint data objects should you sync?

Include these in your integration plan:

• customer master records, including sub-accounts and parent-child relationships
• invoice headers: invoice number, date, amount, currency, payment terms and project or contract reference
• invoice lines, with task and expense detail and the accounting segments Costpoint uses
• contract and award IDs, with time-and-materials (T&M) flags where they apply
• credit memos and adjustments
• payments and remittance references, including ACH, wire, check images and lockbox rows
• unapplied and suspense balances, with journal IDs for traceability
• aging buckets and AR ledger balances, which you'll use as reconciliation checkpoints

Use stable contract or project IDs as your main matching keys rather than invoice numbers. Invoice numbers often get reformatted or truncated as they pass through customer AP systems, and an unstable key produces false exceptions from the first day.

What Costpoint-specific problems should you expect?

ID mismatches. A subcontractor tool or a customer's AP system often numbers invoices differently from Costpoint. Build a mapping layer that normalizes IDs before matching starts.

Multi-entity billing. One customer can receive invoices from several legal entities, each with its own GL. Capture the billing entity on every invoice and make ledger routing part of the matching rules, so each payment posts to the right entity. Our post on AR automation for Oracle covers the same cross-entity problem in a larger ERP estate.

Progress billing and retainage. With milestone invoices and retainage, a payment that looks short may be correct. Sync funded amounts and retainage percentages so the matching engine can tell a normal partial payment from an actual short pay.

T&M invoices. Customers sometimes pay the labor on one task and dispute the materials on another. Header-level matching can't see that, so bring line-level detail into the integration for T&M invoices.

Supporting documents. Agencies and primes often ask for supporting documents with each invoice, and a missing attachment can hold an invoice in an agency system or AP portal for weeks. Check that the integration carries attachments and validates the required paperwork before submission.

When the system can't resolve an exception, it should send it to a person with the remittance and the related invoices attached.

How should cash application work so month-end stays clean?

Only high-confidence matches should be applied automatically, with the rest going to an exception queue where someone reviews them with full context. Before running against production data, check the GL effects with a sequence you can repeat at month-end:

1. Stage transactions in a sandbox, so proposed matches go to a staging area instead of Costpoint journals.
2. Generate test journals and compare the debits and credits to what your team would book manually.
3. Run a Costpoint aged trial balance before and after the test, and confirm that total AR and unapplied cash move as expected.
4. Check that unmatched payments land in the correct suspense account with a journal ID you can trace.

Run the sequence again during month-end close in the pilot to see whether automation introduces any reconciliation differences.

What pilot tests show an integration is ready?

Use real Costpoint data, including the messy cases.

• Load one month of invoices and historical unapplied payments, including a lockbox file and a set of check images.
• Run a simulated remittance feed with consolidated payments, partial payments, short pays and wires with no remittance detail.
• Create a contract-billing dispute and confirm the platform pauses outreach and leaves Costpoint balances untouched.
• Check a representative sample for correct invoice-to-payment mapping and an audit trail on every proposed write-back. Confirm there were no unintended GL adjustments.

During the pilot, track the share of payments matched automatically and the size of the exception queue. Mapping gaps are the usual reason an exception queue fills up in the first week after go-live.

How do you handle AP portals and agency submission?

Many Costpoint customers submit invoices through a prime's AP portal, such as Ariba or Tungsten, or through an agency system. When a portal sits in the payment path, submission needs to be automated too, or invoices will still stall there. Ask any vendor whether it can attach contract-required documents to a submission and resubmit after a rejection.

Before go-live, submit a sample invoice with every required attachment and confirm it shows correctly on the receiving end. Then test resubmitting an invoice that was rejected for formatting.

What will Costpoint procurement and security reviews ask for?

Reviews are thorough in defense and government contracting. Have these ready:

• SOC 2 Type II report. Most reviews start here, and ISO 27001 certification helps if the vendor has it.
• Encryption and key management. How data is encrypted in transit and at rest, and how keys are managed.
• Data residency. Where data is stored and processed, including any ITAR or CUI constraints.
• Access controls and audit logs. Role-based permissions, and a log of every user action and system event that can't be altered.
• Rollback plan. How any write-back to Costpoint can be reversed, including approval thresholds and staged writes.

What should a Costpoint demo show?

Ask vendors to use your data or a sanitized sample, and to:

• match a real payment to a Costpoint invoice and show what gets written back
• split one bulk payment across invoices on several contract numbers, showing each step
• load a lockbox file and check images, then show proposed matches and exceptions
• show disputes and contract holds pausing outreach without changing Costpoint balances
• walk through the audit trail and roll back an incorrect write-back

Rule out any vendor that requires replacing Costpoint or can't map its accounting segments.

What does a phased rollout look like?

Phase 1: Sandbox and pilot. Connect a Costpoint sandbox, map the objects above and run the pilot plan on a month of real data. Move on only after GL effects and exception handling check out.

Phase 2: Commercial customers. Go live with high-volume customers who don't have contract-billing complexity, and refine matching rules on the simpler invoices.

Phase 3: Contract and project billing. Extend automation to government contracts with T&M and progress billing, adding contract-specific logic on top of the Phase 2 rules.

Involve AR operations, your Costpoint administrator, treasury and the contracts or compliance team from the start, along with someone who knows your contract-billing edge cases. Each phase should have an acceptance gate, so nothing moves forward until the previous phase reconciles cleanly.

How does Monk handle this?

Monk runs as the invoice-to-cash layer above Costpoint and handles the work on each invoice after it's issued, while Costpoint keeps the ledger.

Monk's team builds the Costpoint connection during onboarding rather than offering it as a self-serve connector. Monk pulls invoices from Costpoint along with the customer and contract records behind them. Which fields move in each direction is agreed during scoping, along with a timeline that depends on your stack. Details are on the Deltek Costpoint integration page.

On delivery, Monk submits invoices into more than 600 corporate AP portals and uploads 87% of them autonomously. Across the $2B+ in receivables Monk manages, 92% of enterprise invoices have to go through a customer's portal. For invoices moving through agency systems, Monk tracks where each one sits and keeps the follow-up going.

Julia, Monk's AI agent for Intelligent Collections, reads replies and answers what the customer actually asked, such as a request for a missing certificate, instead of moving to the next reminder in a sequence. Julia reaches customers with a 24% higher response rate than standard dunning, and Monk resolves 90% of collections with zero human intervention.

Cash application starts with customer-defined rules. These are written in plain language and take priority over everything else. Below those, deterministic matching on amount, memo, counterparty and timing handles clean payments, and LLM inference works on what's left. The AI layer never applies a match on its own. About 80% of payments match automatically, rising to 95% with suggested rules.

Monk is SOC 2 Type II compliant and ISO 27001 certified. Across its first 100 customers, Monk has cut DSO by more than 40% on average and saved teams about 26 hours a month.

Where should you start?

Start with your unapplied cash and suspense balances in Costpoint.

Age them and find out who owns each one. If the average unapplied receipt is more than two weeks old, the handoff between cash application and collections is probably adding days to your DSO.

Then pull every invoice open more than 60 days and check whether the customer's system actually accepted it. Invoices that were never accepted, usually because of a missing attachment or a PO problem, are often the quickest cash to recover.

Frequently Asked Questions

Does Monk integrate with Deltek Costpoint?

Yes. Monk's team sets up the Costpoint connection during onboarding and pulls invoices along with the customer and contract records behind them. Costpoint stays the system of record. During scoping, ask which fields move in each direction and how anything written back reconciles.

Which Costpoint fields cause the most matching problems?

Truncated or reformatted invoice numbers cause the most trouble, along with project or contract IDs that differ between Costpoint and subcontractor systems. Normalize them before matching, for example by stripping leading zeros and keeping a map that links external references to Costpoint IDs.

How do you apply one bank transfer to invoices on several Costpoint projects?

Use split-apply matching. The system reads the remittance detail to find each invoice reference inside the bulk payment, then applies each portion to the right project or contract line. Contract or award IDs are usually the most reliable keys. If remittance detail is missing, the payment goes to the exception queue with whatever context is available.

What happens to unapplied cash and suspense balances after automation runs?

Unapplied cash stays in suspense, tagged with a traceable journal ID, until a match is confirmed. Once a match passes the acceptance check, a journal entry is proposed that clears suspense and applies the payment. Compare suspense balances before and after each batch to confirm nothing is left orphaned.

Can FAR/DFARS attachments stay bundled with the invoice?

They should. Required documents, such as certificates and cost breakdowns, need to travel with both the invoice email and any portal or agency submission. Test this before go-live with a sample invoice and confirm the attachments show correctly on the receiving end.

How do we show auditors that automation didn't change accounting controls?

Keep logs of every match, write-back, escalation and manual override, along with the acceptance-check record for each approved write-back. During the pilot, compare a sample of automated results against manual bookings and keep the results for auditors.

What rollback controls should we require before allowing journal write-backs?

Require staged writes, so proposed journals wait for review before they post, and approval thresholds above a dollar amount you set. Any committed write-back should be reversible without manual journal entries.
