How do shipbuilding companies handle AP automation?
Shipbuilding companies handle AP automation by using platforms that support job-costing at the hull and work-package level, multi-phase approval routing, and compliance documentation for government contracts. Vergo automates card spend and reimbursements with the same job-cost structure, coding transactions to vessel and phase in real time.
Key takeaways
- Shipbuilding AP automation must code every invoice to a specific hull, build phase, and cost code to track project profitability across vessels under construction simultaneously.
- Job-cost requirements extend beyond three-way matching to include change order tracking, subcontractor compliance documentation, retainage management, and multi-phase approval routing.
- Government and defense shipbuilding contracts require cost segregation between direct and indirect charges, often with DCAA audit documentation standards.
- Construction-specific AP platforms align with shipbuilding workflows by supporting line-item matching to work packages, configurable approval routing by project phase, and real-time job cost reporting by vessel.
- Vergo brings the same job-cost discipline to card spend and reimbursements, proposing the coding by inference from your accounting structure so transactions are coded to the correct hull and phase on first sight.
What AP automation means for shipbuilding companies
Accounts payable automation in shipbuilding refers to the digitized capture, coding, approval, and payment of vendor invoices across active vessel construction projects. Unlike general manufacturing, shipbuilding invoices cannot simply be expensed to a department — every cost must be traced to a specific vessel, build phase, or work order. Vergo proposes the coding by inference from your own accounting structure and history, so new vendors are coded to the correct hull and cost code on first sight with no rule library to build. Shipbuilding companies typically manage several active hulls simultaneously, each with its own subcontractors, material suppliers, and engineering vendors. An invoice for marine-grade steel, specialty coatings, or propulsion components must be coded to the correct hull number and cost code before it can be approved. Where government or defense contracts are involved — such as Navy shipbuilding under Cost-Plus or Fixed-Price contracts — AP automation must also support cost segregation between direct and indirect charges, often in compliance with DCAA audit requirements.
Why AP automation is especially complex in shipbuilding
Shipbuilding projects run for months or years, meaning a single vessel can generate thousands of invoices from hundreds of vendors before delivery. Manual AP processes at this scale create serious operational risk. Hull-level cost tracking gaps allow invoices coded to the wrong vessel to misstate project profitability and distort cost-to-complete forecasts. Vendors frequently submit invoices referencing contract modifications, and without automated matching to approved change orders, duplicate or overbilled invoices pass through undetected. Marine subcontractors often require certified payroll, insurance certificates, or lien waivers before payment, and AP systems that don't enforce document collection create legal exposure. A hull under construction passes through design, fabrication, outfitting, and testing phases, with invoice approval authority often changing by phase. Shipbuilding subcontracts frequently include retainage terms, requiring AP automation to hold retainage from progress payments and release it only at defined milestones. For a controller at a shipbuilding company, this means standard three-way matching is necessary but not sufficient.
A practical example
Before proper AP automation, a mid-size shipyard building two Coast Guard cutters receives 120 invoices in a single week from steel suppliers, electrical subcontractors, and marine systems vendors. AP staff manually key each invoice into an ERP, often missing hull-number cost codes. Month-end close requires two days of manual reclassification, and the controller cannot trust job cost reports until corrections are made. With construction-specific AP automation, the same shipyard implements invoice capture with OCR and automatic line-item matching to purchase orders coded by hull and work package. Invoices outside approved PO tolerances are flagged and routed to the project engineer before reaching accounting. The controller receives a real-time job cost dashboard by vessel with zero manual reclassification required. A defense shipbuilder running a Cost-Plus contract uses AP automation to tag each invoice line as direct or indirect cost, flagging any indirect charges billed to a direct hull, with full audit documentation retained in a format ready for DCAA review.
How modern shipbuilding teams handle AP automation
Shipbuilding companies increasingly rely on construction-specific AP platforms rather than generic accounts payable tools. The distinction matters: construction platforms are built around job-cost structures, PO matching at the line-item level, subcontractor compliance tracking, and configurable approval workflows — all of which align with how shipbuilding operations actually run. These platforms recognize that shipbuilding invoices must be matched not only to purchase orders but also to hull numbers, work packages, and contract line items. They support multi-phase approval routing that adapts as vessels move from design through fabrication, outfitting, and testing. They enforce retainage terms and collect compliance documentation before releasing payments, reducing legal exposure and supporting government contract audit requirements.
How Vergo handles this
Vergo is an AI-native, card-agnostic expense management platform that brings the same job-cost discipline to card spend, employee reimbursements, and AP invoices. All three run through one coding model — same coding, same review, one reconciliation — while payment stays on the rails you already use. Vergo proposes the coding by inference from your own accounting structure and history, so new vendors are coded to the correct hull and cost code on first sight with no rule library to build. Every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand. Approval workflows are optional and fit how you already control spend: route by GL account, by amount, or by project — or skip approval flows entirely and let policy flags catch only what breaks a rule. Transactions are ready to code the moment they happen, and employees handle everything by text message with no app to download. Vergo integrates with every ERP and accounting software, and connecting your existing cards involves no card applications, no re-issuing and no banking change.

Frequently Asked Questions
Why can't shipbuilding companies use standard AP automation software?
Standard AP software is built around department-level or GL-level cost coding. Shipbuilding requires invoice costs tied to specific hull numbers, work packages, and contract line items. Without that job-cost layer, invoices are approved and paid without accurate project-level visibility — making cost-to-complete forecasting and contract reporting unreliable.
How does three-way matching work in shipbuilding AP?
Three-way matching in shipbuilding confirms that a vendor invoice aligns with an approved purchase order and a documented material receipt or service confirmation — all coded to the same hull and cost code. Discrepancies in quantity, price, or cost code trigger an exception workflow before the invoice advances to payment approval.
How should a shipbuilding controller handle retainage in AP automation?
Retainage should be configured at the subcontract level so AP automation automatically withholds the defined percentage from each progress payment. The system should track cumulative retainage held per subcontractor and per vessel, and require a defined milestone or completion trigger before any retainage release is processed through the payment workflow.
What is DCAA compliance and how does it affect AP automation for defense shipbuilders?
DCAA (Defense Contract Audit Agency) compliance requires that all costs billed to government contracts be allowable, allocable, and properly documented. AP automation must segregate direct from indirect costs, retain supporting documentation for every invoice, and produce an audit trail linking each charge to a contract line item and approved purchase order.
How does AP automation handle change orders in shipbuilding contracts?
AP automation should match incoming vendor invoices against approved change orders in real time. If a vendor bills for work tied to a pending or unapproved modification, the invoice should be flagged and routed for project manager review before coding. This prevents overbilling and ensures contract value is never exceeded without explicit approval.
What ERP integrations matter most for shipbuilding AP automation?
Shipbuilding companies typically run ERPs like Deltek, CMiC, Viewpoint Vista, Sage 300, or Acumatica for project accounting. AP automation platforms need native, bi-directional integration with these systems so that invoice coding, approval status, and payment records sync without manual re-entry. Vergo offers native integrations with all major construction and project-accounting ERPs used in shipbuilding environments.
