The operating system for physical bunker-fuel suppliers and barge operators — AI-assisted nomination intake, live barge-fleet scheduling, an ISO 8217 quality auditor, and a claims-and-disputes workbench that seals a defensible evidence bundle before the dispute even starts. A two-minds design keeps every price, tax line, quality verdict and credit block on a deterministic, versioned rules-pack, with LLM features isolated to drafting and parsing and clearly labelled advisory; a tamper-proof ledger and one-click sealed exports make every stem traceable end to end.

BunkerOS is built for bunker supply & barge ops teams in logistics. It is delivered under Outcome-as-a-Service: Xamun invests the build, deploys it on your infrastructure, and you pay per transaction the system processes.
BunkerOS carries the following regulatory and compliance surface, enforced in the workflow rather than documented beside it. The GraphIQ compliance layer keeps these rules current as they change.
Not a generic logistics platform with a fuel bolt-on. Every module is shaped around how physical bunkering actually works — nomination to cash.
AI-assisted nomination intake Raw email or WhatsApp messages are parsed into structured nominations — vessel, quantity, ISO grade. Advisory only; nothing touches the ledger until a human confirms it.
Live barge fleet scheduling A real-time gantt across every barge and berth, with conflict detection before a nomination collides with an existing stem.
ISO 8217 quality auditor Lab certificate values audited against the governing edition and grade — density, sulphur, viscosity, water — with ISO 4259 reproducibility margins and an edition-divergence view.
Claims & disputes workbench Time-bar tracking, sealed evidence bundles and an advisory response draft the moment a dispute is raised — never the final word, always defensible.
Dual-approved rules-pack governance Every pricing, tariff and quality rule that governs a calculation is versioned, diffed against the active pack, and requires dual sign-off before it goes live.
Credit & compliance board Counterparty exposure, credit blocks and compliance status computed deterministically — never left to a spreadsheet formula that silently breaks.
Invoicing & ERP console Delivery-to-invoice in one flow, itemized and tied back to the ledger entry that created it — reconciles to the cent, on demand.
Buyer portal Counterparties see their own orders, invoices and claims live, from a mobile-first portal — no phone calls to check delivery status.
Role-based operations Distinct workspaces for operations, dispatch, credit, claims, finance, barge masters and administrators — each scoped to exactly its job.
Real screens from the live demo you can open above. Your own deployment is a separate instance, branded and configured to your operation.
Stacked against the three ways bunker suppliers run their operations today.
| Capability | BunkerOS Purpose-built for bunkering | Legacy maritime ERP(tanker-fleet suites) | Generic logistics SaaS(global vendors) | Spreadsheets / email |

Under Outcome-as-a-Service, with no upfront CAPEX. What you open above is a demo instance; what you buy is your own separate deployment — on your infrastructure, under your brand, source-available, and configured to how your operation actually works. Xamun invests the build, and you pay a per-transaction fee on what the system processes. A slow month is a small invoice; if it does not run, you do not pay.
Bring us one workflow and we will show you BunkerOS running it.
