Tank Inventory & Compliance App
Kissflow tracks tank gauge readings, inventory reconciliation, leak-detection and tightness testing schedules, and SPCC and regulatory recordkeeping for every storage tank, so the answer to when a tank's tightness test is due, or whether its inventory reconciles, is on a dashboard rather than in three files.
Trusted by energy operators worldwide
A storage tank's leak-detection test comes due on a regulatory clock that does not pause for a busy quarter
Every tank on a pad or at a terminal carries its own testing calendar, tightness testing, calibration, SPCC plan review, and its own inventory reconciliation between what the gauge says and what the books say. A binder can hold last year's test certificate. It can't flag that this tank's test is due in three weeks, or that this month's gauge readings don't reconcile with metered movements in or out.
Kissflow tracks tank inventory and compliance as one governed record per tank: gauge readings captured and reconciled against expected volume, leak-detection and tightness test scheduling with alerts ahead of the regulatory due date, SPCC and UST or AST recordkeeping tied to the tank, high-level and overfill alarm events logged and linked to corrective action, and reporting across the whole tank farm. Automatic tank gauge hardware stays the system of record for real-time level data; Kissflow is where the reconciliation, compliance calendar, and audit trail live.
Terminal and facility leads configure tank records, test intervals, and alarm thresholds in the visual builder. Every reading, test date, and alarm carries a timestamp, so a regulator's question about a specific tank's compliance history is a dashboard pull, not a file search.
What a binder of tank test certificates misses
Test due dates aren't tracked centrally
Each tank's tightness-test or calibration date lives in a separate file, easy to miss across a whole tank farm.
Gauge readings don't reconcile automatically
A variance between gauge readings and metered movement isn't flagged until someone manually checks the numbers.
Alarm events aren't linked to action
A high-level or overfill alarm gets noted but doesn't connect to a documented corrective action.
Compliance status is invisible across tanks
Answering which tanks are current on testing and which are at risk takes a manual pull across every file.
Six modules. Built so a test due date never gets buried in a busy quarter.
Every module ships with default forms, routing, and dashboards. Configure each one to your tank farm in the visual builder.
Tank gauge reading capture
Captures gauge readings per tank, tied to timestamp and location across the facility.
Inventory reconciliation
Compares gauge readings against expected volume from metered movements and flags variance.
Leak detection and tightness test scheduling
Tracks each tank's required test interval and alerts ahead of the regulatory due date.
Regulatory compliance recordkeeping
Maintains SPCC and UST or AST recordkeeping tied to each tank, ready for a regulatory inspection.
High-level and overfill alarm log
Logs an alarm event against its tank and links it to any resulting corrective action.
Tank farm reporting
Rolls up inventory, testing status, and alarm history across every tank on the facility.
From request to system of record in four steps
Capture
A gauge reading or alarm event is logged against its specific tank.
Validate
Inventory is reconciled against expected volume, and any variance is flagged.
Track
Test intervals and regulatory recordkeeping are tracked, with alerts ahead of each due date.
Report
Inventory, compliance status, and alarm history roll up across the tank farm, so the app is the record for when a tightness test is due or whether a tank reconciles.
What changes when tank inventory and compliance run on Kissflow
| Process | Before Kissflow | On Kissflow |
|---|---|---|
| Test due dates | Tracked per tank in separate files | Alerted ahead of the regulatory due date on one calendar |
| Inventory reconciliation | Checked manually against metered movement | Flagged automatically when readings don't reconcile |
| Alarm handling | Noted but not linked to action | Logged and tied to a documented corrective action |
| Compliance visibility | A manual pull across every tank's file | Visible on one dashboard across the tank farm |
| Inspection readiness | A file search when a regulator asks | A dashboard pull with a full timestamped history |
| Cross-tank risk view | Not visible without manual compilation | Rolled up by testing status and variance risk |
Connects alongside your automatic tank gauge and metering systems
ATG hardware and metering instrumentation stay the system of record for real-time readings. Kissflow reconciles inventory and tracks the compliance calendar around it.


Built so a test due date never gets buried
Test alerts ahead of the deadline
Every tank's tightness-test or calibration date surfaces before it's due, not after.
Reconciliation flagged automatically
A gauge-to-metered variance is caught the moment it's found, not on a manual check.
Alarms tied to corrective action
A high-level or overfill event connects directly to the action taken in response.
Live in weeks
Tank records and test intervals configure in the visual builder, without a systems project.
Regulatory recordkeeping in one place
SPCC and UST or AST records for every tank are ready for inspection without a file search.
Access controlled by facility and tank
Role-based access scopes who can view or edit tank records by site.

Get SupportThat app tracks discrete stocked items, spares, consumables, and chemicals, across bins, yards, and warehouses. This app tracks bulk product, crude, fuel, or NGLs, held in storage tanks, with tank gauging, leak-detection test scheduling, and regulatory recordkeeping specific to tank compliance.
That app tracks the operating line-up, which tanks are in service and what's moving between them right now. This app tracks each tank's inventory volume alongside its regulatory compliance status, tightness testing, calibration, and SPCC recordkeeping.
No. ATG hardware and instrumentation stay the system of record for real-time level readings. Kissflow captures the readings that matter for inventory reconciliation and regulatory compliance tracking.
Configurable by jurisdiction and tank type, commonly leak-detection and tightness testing intervals, SPCC plan requirements, and UST or AST recordkeeping obligations.
An alarm event is captured against the specific tank, timestamped, and linked to any resulting corrective action, feeding both the inventory and compliance record.
Configurable by role, typically a terminal or facility supervisor reviews a variance above threshold before it's recorded as resolved.
Tank records, test intervals, and alarm thresholds configure in the visual builder, without an engineering project.
Kissflow is certified to SOC 1, SOC 2, SOC 3, and ISO/IEC 27001, with role-based access by facility and tank.
