GAT-Ship has run port calls for agents since 1995 and its incumbency is real, thirty years of maturity and a deep Nordic customer base. Base is the modern alternative for agencies that want the same port call workflow plus native financial management, real-time principal visibility through Base Connect, and embedded compliance and intelligence data built into the platform. This is the most direct head-to-head in the category, and we will be honest about the tradeoffs.
GAT-Ship incumbency advantage in port agency
Base pricing model vs GAT-Ship per-port-call
Native QuickBooks and Xero sync out of the box
Principal portal Base has, GAT-Ship does not
Both tools run the port call workflow. The real differences show up in financial management, principal visibility, and embedded intelligence. Here is the honest side-by-side.

GAT-Ship handles the port call well and exports to your accounting system through its REST API. That is a project. Base runs multi-stage invoice approvals, OCR AP automation, and native QuickBooks integration or Xero sync inside the same platform. The finance side does not live somewhere else.
GAT-Ship has no principal portal. Your principals see the DA by email after the fact and every charge question turns into a round-trip. Base Connect gives principals real-time visibility into the same audit trail you see, on the port call that is still open. No more back-and-forth on line items.
GAT-Ship is a mature, battle-tested platform with real strengths. Here are the scenarios where you should pick GAT-Ship over Base, honestly.
GAT-Ship recommends roughly 300 to 500 port calls per year as a minimum for its pricing to make sense, and under that threshold the per-port-call model can run cheaper than a per-user tier. If you are a smaller agency running occasional calls, do the math both ways. GAT-Ship is a legitimately cheaper answer at low volume.
GAT-Ship was founded in Norway and has three decades of customer references across Nordic and European agency markets. If your team hires from that talent pool, your auditors know the reports, and your partner agencies already use it, the local network effect is real and you should weigh it seriously.
If your finance team is committed to its ERP and wants a REST API export model from the operations tool rather than a native accounting integration, GAT-Ship is built exactly for that split. Base is built for teams that want ops and finance in one place. If that is not your preference, GAT-Ship fits more cleanly.
If your team has fifteen years of GAT-Ship history, custom reports, and trained agents across multiple offices, the cost of migration may outweigh the benefit of switching. Base is worth evaluating for your next office or new business line, but a wholesale replacement is not always the right call. We will tell you that on the demo.
GAT-Ship has no embedded compliance or intelligence data. Base ships with sanctions screening, vessel compliance, and tariff lookup live in the platform. Your team checks compliance during the port call, not after the fact in a separate tool with a separate login.
We spoke with port agency teams that evaluated both tools, and in some cases ran a parallel pilot. The pattern was consistent, GAT-Ship got them far on operations, then the financial side and principal questions forced the next decision.
A Base demo walks a real port call the way your agents run it today. We will respect where GAT-Ship is strong, show you where Base does something different, and be honest about whether switching makes sense for your volume and market. No canned pitch, your vessel, your ports.
“We did not want to hear that GAT-Ship was bad. We wanted to hear what would actually change day to day. The honest comparison was what made the decision easy.”

Port agencies that move from GAT-Ship to Base typically have the port call workflow, accounting sync, and principal visibility working within two to three weeks.
