Maritime accounting software built for disbursement invoicing at the pace of port operations. Proforma to final invoicing, multi-currency support, batch billing, and accounting sync. Document generation and financial reporting that match the speed of your port calls.
Maritime accounting is not standard AP/AR. It is disbursement accounting: advance funds for port services, track expenses against multiple vendors, invoice the principal with full charge detail, and reconcile payments across currencies. All while the next vessel is already arriving.
Manual currency conversion
Three currencies on one job. Look up rates this morning. Hope they don’t shift before approval.
Approval is reply-all email
Forwarded threads. No audit trail. The approval lives in someone’s sent folder.
AP costs sit unallocated
Vendor invoices arrive after the FDA goes out. Costs drift without matching to jobs. Margin disappears.
Accounting lags operations
By the time finance closes the month, the next quarter is already underway. Real-time AR is a fantasy.
Create the job from a template. Charge lines pre-load with estimated amounts. Generate the PDA from the job record and send to the principal.
Vessel departs. Update estimated charges to actuals. Add weather delays, additional tugs, emergency launches. The proforma becomes the final with one action.
Multi-stage approval workflow. Line-item accept or reject with documented reasons. On final approval, sync to QuickBooks or Xero automatically.
Your team invoices a Norwegian principal in NOK for a port call where pilot services were billed in USD and tug services in BRL. Three currencies on one job. The spreadsheet approach: look up today’s exchange rate, convert each line item manually, hope the rate has not shifted by the time the invoice is approved.
In Base, each invoice carries its own currency. Exchange rates cache per job and update daily. When your finance team reviews the invoice, both the original currency amount and the converted amount are visible. AR aging reports show outstanding amounts in your base currency with conversion applied.
No manual lookup. No stale rates. Fifteen currencies supported across the platform.
A port agent invoices per vessel call. Each job generates its own FDA with full charge detail. An OSV operator running 12 recurring platform runs per month for the same principal needs a monthly summary, not 12 separate invoices.
Batch invoicing groups jobs into a single summary invoice. Line items organized by vessel, period, or project. The principal gets one document covering all activity for the billing period. Both modes support multi-currency, multi-stage approval, and accounting sync.
Fleet operators use batch invoicing for monthly summaries across dozens of projects. Port agents invoice per job. The system adapts to how you bill, not the other way around.
Proforma → Final
Same job, same template, updated charges. The PDA becomes the FDA in one action.
Multi-Stage Approval
Stage 1 ops, Stage 2 finance, Stage 3 PM. Line-item accept/reject with documented reasons.
AP Vendor Matching
Vendor invoices match to expenses. Unallocated costs surface in AP aging, not at month-end.
15 Currencies
Daily exchange rates. Native and converted amounts. Cached per job to lock rates.
Audit Trail
Who created, who approved, when, and why any line was rejected. Every action logged.
Real-Time AR/AP
Aging reports show outstanding balances today, not after month-end close.
charges tracked across the platform
documents generated (99.95% PDF rate)
currencies with daily exchange rates
charges captured with full audit trail
QuickBooks and Xero handle the general ledger. Base handles disbursement accounting: PDAs, FDAs, multi-currency port call billing, and the approval workflow that connects operations to finance. Base syncs to your accounting system on approval. They are complementary, not competing.
Per-job invoicing for port agents who bill by vessel call. Batch invoicing for fleet operators billing monthly. Multi-currency for international principals. Multi-stage approval for principals who require it. The system adapts to how you bill, not the other way around.
Proforma to final, multi-currency, batch billing, and accounting sync. Built for maritime operators who invoice at the speed of operations.
