Welcome to VesselOne
An overview of the platform, the three user types, and how modules connect.

What is VesselOne?
VesselOne is a multi-tenant SaaS platform built specifically for marine service companies. It brings together work order management, time tracking, vessel records, photo documentation, stock management, and team scheduling into one connected system.
VesselOne is operated by MCY Marine Group Pty Ltd. Marine service businesses subscribe as tenants, each with their own isolated workspace.
Three User Types
VesselOne has three distinct user types, each with different access and responsibilities.
- Company Admin — Full access within your company. Manages vessels, work orders, team members, billing, and settings.
- Technician — Assigned to work orders. Can log time, upload photos, update status, and log materials. Cannot access billing or company settings.
- Vessel Owner — Platform-level user with no company affiliation required. Confirms the boats that are theirs, keeps the service records companies send them, and shares a read-only record by link.
A single person can hold both a company role and a vessel owner account simultaneously. This is called a dual identity and is managed automatically by VesselOne.
How Modules Connect
Every workflow in VesselOne flows through the Work Order as its central record. A vessel must exist before a work order can be created. Team members can be put on jobs as soon as they are added. Company rates must be configured before Time & Materials billing is accurate.
- Vessels → Work Orders (vessel must exist first)
- Team members → Work Orders (put them on jobs as soon as they are added)
- Settings → Rates → Work Orders (rates must be set for T&M billing)
- Work Orders → Time Entries → Cost Summary
- Work Orders → Photos → Send to customer (optional)
