Key takeaways
- Vergo automates AP for shipbuilding by applying AI inference to code invoices to the correct hull, work order, and cost center from the first transaction—no rule library to build, no keyword lists to maintain.
- Effective automation must handle multi-hull allocation, purchase order limits, contract modifications, and allowable-cost tracking.
- Integration with shipyard ERPs ensures approved invoices sync directly into program accounting without manual re-entry.
- Approval workflows should route by hull number, cost category, and program so managers only review their own vessels.
- Exception handling for contract modifications and PO overruns is critical given the long timelines and high vendor volumes in shipbuilding.

What makes shipbuilding AP different
Generic AP automation tools assume one invoice maps to one department or GL account. Shipbuilding doesn't work that way. A single steel delivery invoice might split across three hulls, two work orders and four cost centers. Generic tools force controllers to manually reclassify every line. Manual AP in shipyards is especially painful because programs are long, vendor volumes are high, and cost overruns on a single vessel can be large. Slow invoice processing delays accrual accuracy and distorts vessel-level profitability reports. The core challenges include multi-hull cost allocation where invoices routinely span several active builds, vendor terms tied to program milestones rather than calendar dates, a yard-to-office gap as receiving happens at the dry dock while approval happens in the office, and documentation requirements from classification societies and government customers that demand auditable cost trails per vessel.
Digitizing invoice intake for shipyard vendors
Capture should extract hull numbers, work orders and purchase order references from supplier invoices. Common shipyard vendors—steel suppliers, marine coatings, propulsion system providers—should land on their usual GL accounts and cost centers without manual setup. Marine-aware capture understands the difference between a hull number and a purchase order number, reducing data entry and improving accuracy. The system must parse invoices from marine-specific suppliers whose formats differ from standard commercial vendors. Once invoice data is captured, it feeds directly into allocation and approval workflows, so accounting teams stop keying in hull assignments by hand.
Building approval workflows by vessel and program
Route invoices automatically based on hull number, cost category (materials, labor, outside services) and build stage (hull fabrication, outfitting, sea trials). Assign approval thresholds so project managers only see invoices for their vessel, preventing notification overload and keeping accountability with the team responsible for each build. For example, a materials invoice for Hull 247 during outfitting would route to that vessel's project manager if it exceeds the threshold, while smaller invoices might skip approval entirely. This respects how shipyards are organized, where each vessel functions as a semi-independent profit center. Workflows also need escalation paths for invoices that exceed purchase order values or reference a contract modification.
Automating allocation at line-item level
Split invoices across multiple vessels or dry-dock projects by percentage, quantity or value. Every line item should land on the correct hull, work order and GL account without manual reclassification. A practical example: a marine coatings supplier delivers paint to three active builds in one shipment. The invoice lists each vessel's consumption separately, but accounting must allocate delivery charges proportionally. The split follows material quantity or dollar value, posting each portion to the correct vessel's cost structure. This granular allocation is essential for accurate vessel-level profitability and ensures cost reports reflect true consumption rather than arbitrary conventions. Without line-item automation, controllers spend hours every cycle splitting and re-coding invoices.
Integrating with shipyard ERP and program systems
Push approved invoices directly into Infor LN, IFS, SAP or Deltek Costpoint. Keep vendor master data, work orders, cost centers and purchase orders aligned between the ERP and the AP system so changes in one reflect in the other. Integration eliminates duplicate data entry and ensures invoice coding follows the program structure already set up in your ERP—SAP cost centers and WBS elements, IFS projects and work orders, Costpoint charge numbers. Purchase order awareness matters most: when a PO is issued in the ERP, the AP system should recognize it and flag invoices that exceed the ordered amount. This closed loop keeps overruns from slipping through and gives project managers real-time visibility into how invoices affect their budgets and earned value.
Handling contract modifications and allowable costs
Shipbuilding contracts involve frequent contract modifications, and government programs add allowable versus unallowable cost rules. Look for rules that flag invoice amounts exceeding PO values. Modifications are routine as vessel specifications evolve during the build, and each one affects multiple invoices downstream. The AP process must recognize when an invoice references a modification, confirm it was approved, and code it to the new work order or charge number rather than the original baseline. Allowable-cost treatment requires unallowable items to be coded to their own accounts at entry, not reclassified at year end. Manual tracking is error-prone, especially when hundreds of supplier invoices are in flight across multiple vessels. Consistent coding with receipts and approvals attached gives DCAA-ready audit trails and clear visibility into each program's spend.
How Vergo handles this
Vergo automates AP for shipbuilding by applying AI inference to code invoices to the correct hull, work order, and cost center from the first transaction—no rule library to build, no keyword lists to maintain. Every coding decision shows why it was chosen, so reviewers confirm in seconds instead of re-coding by hand. Approval workflows route by GL account, by amount, or by project, fitting how shipyards already control spend, 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 once they clear, they sync into your ERP. Vergo integrates with Infor LN, IFS, SAP and Deltek Costpoint, so approved invoices post directly into your shipyard's program accounting. Card spend, employee reimbursements, and AP invoices run through one coding model—same coding, same review, one reconciliation—and payment stays on the rails you already use.
Related questions
Frequently Asked Questions
What ERP systems integrate with AP automation for shipbuilding?
Shipyards commonly run Infor LN, IFS, SAP or Deltek Costpoint. For shipbuilding, look for tools that sync hulls, work orders, cost centers and purchase orders with your ERP. Vergo integrates with these systems so approved invoices post without manual re-entry.
How does AP automation handle allowable costs on government shipbuilding contracts?
Each invoice line is coded at entry to the GL account and charge structure your ERP uses, so unallowable items land in their own accounts instead of being reclassified later. Receipts, approvals and coding reasoning stay attached to every line per hull.
What if an invoice needs to be split across multiple vessels?
Shipyard-ready AP tools support multi-hull invoice splitting at the line-item level. You split by percentage, quantity or fixed amount per vessel. Each hull receives its correct cost allocation at capture, without manual journal entries.
How does AP automation affect month-end close for shipbuilding companies?
Automated AP keeps invoices coded and posted in real time, so accruals are accurate before close begins. Shipyard controllers spend less time chasing missing invoices or reclassifying lines across hulls and cost centers.
Can AP automation handle contract modifications on shipbuilding programs?
Yes. Invoices that exceed original purchase order amounts get flagged, which often signals a contract modification. Flagged invoices route to the project manager for review and approval before posting, maintaining budget integrity on each vessel build.
