Maritime Software That Works.
The communication and shipping platform for maritime companies who want to own their data, not rent it. Since 1987 by Reinhardt Software GmbH · Hamburg.
One platform for the way maritime business actually works.
SYSTEM 5 brings your email, chartering, S&P, post-fixture, and shipping workflows into a single shared environment. No tool-switching. No data silos. Just one system your whole team works from.
Communications Deep Dive →Built Different. On Purpose.
Every email, visible to the whole team — with individual read status
Your servers, your data — no forced cloud lock-in
Take what you need — modular from day one
Talk to the developers — and actually get heard
Built for maritime teams where email isn't a task — it's the business.
Chartering Teams
Handle thousands of emails a day without losing pace. Fixture negotiations, counterparty threads, and outgoing circulars stay organized and easy to find, so nothing slips through when volume spikes.
S&P Teams
Every vessel enquiry, every buyer and owner conversation, every circular goes into one workspace the whole team can reach. Step into a deal mid-stream and pull up the full thread in seconds, without hunting down who holds it.
Ship Owners & Operators
Chartering negotiates the fixture, operations runs the voyage, finance invoices, ship management keeps the fleet moving. SYSTEM 5 gives each department direct access to what the others have already done — no forwarding required.
Port Agents
Shifts end; the correspondence doesn't. Threads with vessels, port authorities, and customers are all filed in one place, so the next agent on duty has full context from the first message.
Freight Forwarders
Carrier bookings, consignee instructions, and partner exchanges are all kept in a single folder anyone on the team can open, instead of piecing a shipment's history together from scattered inboxes.
Commodity Traders
A single transaction can pass through several desks before it closes. SYSTEM 5 keeps counterparty talks, confirmations, and logistics coordination in one location the whole desk can work from, so whoever picks it up next can follow the full trail from origination to settlement.
Four reasons companies switch to SYSTEM 5.
Support That Picks Up the Phone.
With us, there is no ticketing system. You speak directly to a person who will help you immediately when you hit any issue — and there's a short, direct path to the developers whenever it's a bug or a good feature idea.
No queue. No tier-one script reading from a knowledge base. Just someone who knows SYSTEM 5, and knows your setup, on the other end of the line.
How Support Actually Works
Call or email — reach a person, not a ticket queue
Quick access to the developers who built the system
Issues handled immediately, not scheduled for next sprint
One team, accountable, since 1987
Built for shipping desks. Not design awards.
SYSTEM 5 is dense, functional, and built specifically for maritime — continuously, since 1987. Every edge case your shipping team will encounter has already been through our system.
Some customers left for better-funded, better-designed alternatives. Most came back. It turns out maritime workflow depth takes decades to build — and we never stopped building it.
Built to work. Not to impress.
