From supplier order to regulatory report, every gallon has one continuous, defensible record.
Flowmark connects fuel ordering, inventory, field execution, reconciliation, forecasting, and reporting through one operational record.
Built for
- FBOs
- Aviation operators
- Multi-location networks
- Fuel operations leadership
The fragmentation problem
Fuel moves continuously. Its data usually doesn't.
Orders, delivery tickets, tank readings, truck movements, aircraft uplifts, reconciliation, finance, and reporting often live across different people and systems. Flowmark connects those movements into one operational record.
- Supplier orders
- Delivery records
- Tank inventory
- Ramp activity
- Reconciliation
- Reporting
One operational record
Every movement, connected
Inside Flowmark
One record, seen from every angle that matters.
Command center
Know what you have, what is committed, what is coming, and what requires attention.
The operating picture for a location or a whole network — inventory, commitments, coverage, and exceptions on one screen, drawn from the same record your teams work in.
- Fuel position
- Committed uplift
- Projected coverage
- Open exceptions
- Upcoming flight demand
- Deliveries & reporting status
Reconciliation
When the numbers differ, Flowmark shows why.
Book inventory, physical observation, and tolerance sit side by side. Physical readings are recorded against the record — they do not silently overwrite the movement history behind it.
- Book inventory vs. physical observation
- Variance against configurable tolerance
- Movement history preserved, not overwritten
- Exceptions surfaced with their source
Reporting
Report from the same record you operate from.
Reports trace back to the transactions that produced them. Submitted snapshots stay fixed, so you can see current versus filed at any time — including fuel and emissions reporting where it applies.
- Source traceability to underlying movements
- Reporting status at a glance
- Submitted snapshots preserved
- Current-vs-filed visibility

Flowmark Field
The record starts where the fuel moves.
Capture operational truth on the ramp, not hours later at a desk. Meter readings, aircraft verification, authorization, and completion records are entered at the point of work — and the app stays aware of connectivity, syncing when a connection returns.
- Next uplift
- Authorized gallons
- Start Fueling
- Aircraft verification
- Meter capture
- Receive Fuel
- Transfer Fuel
- Tank Reading
Offline-aware capture with automatic sync
The operating lifecycle
One gallon. One history.
Fuel moves through procurement, positioning, execution, control, and reporting. In Flowmark, every movement contributes to the same defensible operational record.

Ask Flynn
Ask operational questions against the same underlying record — and get answers you can trace, not guesses. Flynn works from your movements, inventory, and reporting, then shows its evidence.
- Why is Tank 02 at risk?
- Which transactions contributed most?
- What reports are due?
- Which supplier delivery should we move?
- What is my next uplift?
- Where did this reported total come from?
Ask Flynn
ExampleWhy is Tank 02 at risk?
Answer
Tank 02 is projected below its reserve threshold inside the coverage window — uplift demand is running ahead of the planned replenishment.
Evidence used
Confidence
Suggested action
Advance the next supplier delivery or rebalance from Tank 01.

Enterprise & control
Built for controlled aviation operations.
Flowmark is designed around traceability, role-aware workflows, configurable operational controls, and integration with the systems aviation organizations already use.
Tank modes, configured per site
Inventory can be tracked the way each location operates today — and connected further over time.
- Manual
- Connected Gauge
- External Fuel System
Integration-ready by design. Connections to external fuel systems, gauges, and enterprise software are configured per customer.
Role-based access
Scoped permissions per location and function, so people see and change only what they should.
Microsoft Entra ID
Built for enterprise identity, with single sign-on through your existing directory.
Auditable history
Corrections are append-only — recorded against the record, never silently overwritten.
Configurable hierarchy
Model your organization and location structure the way your operation is actually run.
Submitted snapshots
Filed reports are preserved as fixed snapshots, so current-vs-filed is always clear.
Configurable thresholds
Reserve levels and tolerances are set to your policy, not hard-coded assumptions.
Questions
Answers before you ask.
No. Flowmark owns the fuel operational record — ordering through reconciliation and reporting — and is built to hand clean, reconciled data to the enterprise systems you already run, removing manual re-keying between the ramp and the ledger.
Yes. Inventory, orders, and reporting are scoped by a configurable organization and location hierarchy, with role-based access so each site sees its own operation while leadership sees the whole network.
Flowmark is integration-ready by design and supports Manual, Connected Gauge, and External Fuel System tank modes. Specific connections to external fuel systems, gauges, and enterprise software are configured per customer.
