BunkerOS — The bunkering platform that makes every stem defensible

The cost-to-feature problem

Legacy bunker ERP is overkill. Spreadsheets are a liability. BunkerOS is the fit.

Bunker suppliers and barge operators are forced to choose between million-dollar maritime ERP suites built for tanker fleets, generic logistics SaaS that has never heard of ISO 8217 or a time-bar clause, or fragile spreadsheets and email threads that fall apart the moment a buyer disputes a delivered quantity. BunkerOS is purpose-built for the middle — real ISO 8217 quality compliance and a real deterministic ledger, right-sized for a supplier's fleet and owned outright rather than rented.

1 ledger

Nomination → scheduling → execution → claims → invoicing, all in one tamper-proof chain

Live GraphIQ

ISO 8217 spec limits resolved against a real regulatory knowledge graph, not hardcoded tables

9 workspaces

Ops, dispatch, credit, claims, finance, barge master, admin, entities, buyers — each scoped to its job

Sealed evidence

Every claim's time bar, ledger reference and evidence bundle locked the moment a dispute is raised

One platform, the whole delivery

Everything a bunker supplier actually needs

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.

Nomination intake

Nominations parsed by AI, confirmed by a human

Raw email, WhatsApp or broker messages are dropped in and drafted into a structured nomination — buyer, vessel, quantity, ISO grade, tolerance. Nothing touches the ledger until a human confirms it.

Confidence-scored extraction from raw inbound messages
Human-in-the-loop confirmation before the ledger is touched
Vessel IMO validation and exact-match tolerance fields

Quality auditing

ISO 8217 verdicts backed by a live knowledge graph

Density, sulphur, viscosity and water are audited against the governing edition and grade using ISO 4259 reproducibility margins — and the spec limits themselves come from a live regulatory knowledge graph, with a local deterministic fallback if it's ever unreachable.

Edition-divergence view — the same lab result against every ISO 8217 edition at once
Live GraphIQ-backed spec limits, per edition and per grade (RMG380, DMA)
AI-assisted lab-certificate PDF transcription — advisory, never a verdict

Claims & disputes

Defensible before the dispute even starts

The moment a claim is raised, the time bar starts ticking, the evidence bundle is sealed with a ledger-linked hash, and an advisory response draft is ready for a human to confirm.

Cost / complexity →

Right-sized for bunker suppliers

Fujairah and Dubai-anchored suppliers and barge operators get real ISO 8217 compliance and a real ledger, without a tanker-fleet ERP budget or headcount.

Live in weeks, not a saga

Pre-built ISO 8217 quality logic and rules-pack governance mean you configure and go live — instead of funding a multi-year maritime ERP integration.

Defensible by default, not a project

Sealed evidence, time bars and edition-aware quality verdicts are wired into the workflow — so a claim never catches you without evidence.

Built to scale with the fleet

From your first stem to a multi-berth, multi-barge operation with an active buyer portal — one platform grows with you.

Ownership, not rental

You own your bunkering platform — source code and all

BunkerOS is not SaaS. Under a source-available license you receive a copy of the source code, brand it as your own, deploy it wherever you choose, and keep full control of your data and your roadmap.

The source code is yours

You receive the complete source under a perpetual license. Read every line, audit it, and never be held hostage to a vendor's roadmap or release cadence.

Brand it entirely as your own

White-label from the ground up — your name, logo, colors and domain across the buyer portal and staff console. Ship it to market as your product, not ours.

Host it anywhere

Your cloud, your on-prem data center, your region of choice. No mandatory vendor cloud, no per-seat metering, no usage caps that throttle growth.

Your data never leaves your control

Delivery records, lab certificates and dispute evidence sit in infrastructure you own — making data residency and jurisdiction-specific compliance far simpler to demonstrate.

Customize without limits

Modify and extend the platform for your own trade lanes, grades and workflows. The code is yours to evolve — by your team or ours — as the fleet grows.

Perpetual license

A one-time license to the delivered version, yours to run indefinitely. No subscription that can be switched off, no renewal leverage held over you.

Source-available, not open-source. You get the code for your own internal business use, with the right to brand, host, modify and run it in perpetuity. Reselling it or offering it to third parties as a service is reserved. The full terms are short and in plain English.
