How do I automate AP automation for shipbuilding companies?

Key takeaways

• Vergo automates AP for shipbuilding by applying AI inference to code invoices to the correct vessel, project phase, and cost code from the first transaction—no rule library to build, no keyword lists to maintain.
• Effective automation must handle job-cost allocation, retainage deductions, change orders, and commitment tracking natively.
• Integration with shipyard ERPs ensures approved invoices sync directly into project accounting without manual re-entry.
• Approval workflows should route by vessel number, cost category, and project phase so managers only review their own projects.
• Exception handling for change orders and retainage 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 project phases, and four cost codes. Generic tools force controllers to manually reclassify every line. Manual AP processing in shipyards is especially painful because project timelines are long, vendor volumes are high, and cost overruns on a single vessel can reach millions. Slow invoice processing delays accrual accuracy and distorts vessel-level profitability reports. The core challenges include multi-vessel cost allocation where invoices routinely span multiple active builds, retainage and progress billing with payment terms tied to construction milestones rather than calendar dates, field-to-office disconnect as receiving happens at the dry dock while approval happens in the office, and regulatory documentation requirements from marine classification societies that demand auditable cost trails per vessel.

Digitizing invoice intake for shipyard vendors

Configure optical character recognition to extract vessel identifiers, hull numbers, and marine cost codes from supplier invoices. Map common shipyard vendors—steel suppliers, marine coatings, propulsion system providers—to default cost code templates. Construction-aware OCR understands the difference between a vessel number and a purchase order number, reducing manual data entry and improving accuracy. The key is ensuring the system can parse invoices from marine-specific suppliers whose formats differ from standard commercial vendors. Once invoice data is captured, it feeds directly into job-cost allocation and approval workflows, eliminating the need for accounting teams to manually key in vessel assignments or cost codes.

Building approval workflows by vessel and project phase

Route invoices automatically based on vessel number, cost category (materials, labor, subcontractor), and project phase (hull fabrication, outfitting, sea trials). Assign approval thresholds so project managers only see invoices for their vessel, preventing notification overload and ensuring accountability stays with the team responsible for each build. For example, a materials invoice for Hull 2047 during outfitting would route to that vessel's project manager if it exceeds the threshold, while smaller invoices might skip approval entirely. This approach respects the organizational structure of shipyards, where each vessel functions as a semi-independent profit center. Workflows must also accommodate escalation paths for invoices that exceed committed purchase order values or require exception handling for change orders.

Automating job-cost allocation at line-item level

Split invoices across multiple vessels or dry-dock projects using percentage-based or unit-based allocation rules. Every line item should land on the correct cost code 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. Automated allocation rules apply the split based on 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 analysis and ensures that cost reports reflect true resource consumption rather than arbitrary accounting conventions. Without line-item automation, controllers spend hours every cycle manually splitting and re-coding invoices.

Integrating with shipyard ERP and project management systems

Push approved invoices directly into Sage 300, Viewpoint, or your shipyard ERP. Sync vendor master data, cost codes, and commitment tracking bidirectionally so that changes in the ERP reflect in the AP system and vice versa. Integration eliminates duplicate data entry and ensures that invoice coding aligns with the cost structure already established in project management systems. Bidirectional sync is particularly important for commitment tracking: when a purchase order is issued in the ERP, the AP system should recognize it and flag invoices that exceed the committed amount. This closed-loop approach prevents cost overruns from slipping through and gives project managers real-time visibility into how invoice processing affects their budgets and earned value calculations.

Handling change orders and retainage

Shipbuilding contracts involve frequent change orders and retainage holdbacks. Configure rules that flag invoice amounts exceeding committed PO values or that auto-calculate retainage deductions. Change orders are routine as vessel specifications evolve during construction, and each change affects multiple invoices downstream. The AP system must recognize when an invoice references a change order, verify approval of the change, and adjust commitment balances accordingly. Retainage—typically five to ten percent held until project milestones—requires the system to calculate deductions automatically and track retained amounts separately for eventual release. Manual retainage calculation is error-prone and time-consuming, especially when hundreds of subcontractor invoices are in flight across multiple vessels. Automated retainage ensures compliance with contract terms and provides visibility into outstanding holdbacks.

How Vergo handles this

Vergo automates AP for shipbuilding by applying AI inference to code invoices to the correct vessel, project phase, and cost code 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 every ERP and accounting software, ensuring that approved invoices post directly into your shipyard's project accounting system. 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.
