Everything checked is a pair
An audit is not really interested in any single record. A stock figure on its own can say anything; a meter reading on its own can say anything. What is checked is whether two records that were produced by different means agree.
That principle tells you what to keep and, more usefully, what shape to keep it in. A record that cannot be set against its counterpart on the same date is not much use, however carefully it was written.
It also means an outlet already reconciling daily has almost nothing extra to do. The pairs are the same ones.
Stock and meters
The central pair. Book stock derived from opening stock, deliveries and dispensed litres, against the dip that was actually measured.
- Daily stock register, per tank — opening, deliveries, dispensed, book stock, dip, variance.
- Daily meter readings, per nozzle — opening, closing, testing litres, litres sold.
- Evidence that nozzle litres reconcile against the tank each one draws from.
- The tank calibration chart for each tank, and evidence the dip was converted using that tank's own chart.
- Water dips recorded separately from product.
The question behind the question
A register where book stock and dip agree exactly, every day, invites more scrutiny rather than less — it usually means the dip was written to match the book rather than measured. A small, varying, explainable variance is the shape of a record that was actually kept.
Deliveries
Each delivery is checked against what actually entered the tank, so both sides have to exist.
- Invoice with quantity, per compartment and per tank.
- Observed density and temperature, and the density corrected to 15 °C.
- Pre-delivery dip and post-settlement dip for the receiving tank.
- Any seal discrepancy, recorded in writing at the time rather than remembered.
- Shortage claims raised, and when.
Calibration and equipment
Dispensing units are measuring instruments, and their verification is a statutory matter as well as a commercial one.
- Current verification and stamping for every dispensing unit.
- Records of testing litres dispensed into a test measure and returned.
- Maintenance and repair history, particularly any dispenser replacement — a replacement resets the totaliser and needs two reading pairs, not one.
Collections, expenses and receivables
The second pair: revenue the litres imply, against what was actually collected.
- Daily collections split by cash, UPI, card, fleet and credit — not pooled.
- Settlement statements for the digital channels, reconciled against recorded collections.
- Drawer expenses, with documentation above whatever threshold you set.
- Credit customer ledgers, aged, reconciling against credit sales in the daily sheets.
- Rate change records, so a day with two prices can be valued correctly.
Licences and statutory
The paperwork side. Exactly what applies depends on your state, whether the site is on a national or state highway, and the terms of your dealership — so treat this as the shape rather than the list.
- Explosives licence for petroleum storage, current.
- Fire service and district authority no-objection certificates.
- Pollution control board consents.
- Weights and measures verification certificates.
- Trade licence, GST registration for the non-fuel business, shop and establishment registration.
- Renewal dates tracked somewhere that is looked at, rather than in a file that is opened when something expires.
Preparing, honestly
The realistic preparation for an audit is not a week of assembling documents. It is that the pairs above were being compared as they were produced, so assembling them is a matter of exporting a date range.
An outlet that reconstructs its records in the week before an inspection is producing a summary of primary records rather than the records themselves, and the difference is usually visible. It is also the week in which errors that were correctable in March are discovered to be permanent.
Frequently asked questions
How long should petrol pump records be kept?
Longer than any minimum, because their operational value is in the series rather than in any single day. A stock variance is meaningless as one figure and diagnostic across a year — which is also the horizon over which a slow leak becomes visible. Statutory retention periods vary by record type and state; keep to whichever is longer.
Is a digital record acceptable?
Requirements differ by state and by the terms of your dealership, and some records may need to be producible in a particular form. What is universally true is that a digital record that exports to Excel and PDF over an arbitrary date range is easier to produce on demand than a stack of notebooks, whichever form is ultimately required.
What is the most common finding?
Records that exist but cannot be set against each other — meter readings in one book, stock in another, cash in a third, with no date-by-date comparison anywhere. Each is individually complete and the pair that would have meant something was never formed.
