# Licences, calibration and the renewal calendar — Octyn > Keep every fuel station licence, calibration and policy on one renewal calendar. Track expiry dates and lead times, not memory. Canonical: https://octynerp.com/guides/renewal-calendar # Licences, calibration and _the renewal calendar_ Build one register of every licence, certificate, calibration record and policy the station depends on, with expiry dates and lead times, so renewals never depend on memory. Read **5 minutes** Updated **1 November 2026** For **Owners and managers** By **The Octyn team** **Someone remembers the licence expiry. Usually.** A fuel station runs on a stack of documents. Different authorities issue them, each on its own cycle. Miss one and the cost is a fine, a shutdown notice, or an insurer that turns down a claim. The fix is a register and a calendar, not a better memory. ## 01 The register Keep one list, and keep it current. Give it a row for every document the station needs to operate. Each row holds the issuing authority, the document number, and the issue and expiry dates. It also holds how long the renewal takes, who at the station owns it, and where the scanned copy is. If a row cannot be filled in, that is the first renewal to chase. ## 02 What usually belongs on it - The licence to store and handle petroleum products, and any explosives approvals your site needs. - Fire safety certificate from the local authority. - Weights and measures stamping certificates for every dispenser, with the date each was last verified. - Environmental consents, where the site needs them. - Trade and shop licences from the local body. - Insurance policies: stock, premises, public liability, vehicles. - Calibration and maintenance records for tanks and dispensers. Rules differ by state and by site. Treat this as a starting list, and check it against what your OMC and local authorities ask of you. ## 03 Lead times, not expiry dates The date that matters is not the expiry. It is the last day you can start the renewal and still finish in time. Inspections need booking, authorities take weeks, and one document often needs others first. Put that start date on the calendar, with a reminder two weeks before it. Treat the expiry date as the hard deadline. The petroleum licence shows why. Under the [Petroleum Rules, 2002](https://peso.gov.in/web/sites/default/files/2019-12/PR-2002-English-full.pdf) (rule 148), the renewal application must reach the licensing authority at least 30 days before expiry. Miss that and the fee doubles. More than 30 days after expiry, the licence can no longer be renewed. ## 04 Calibration is a schedule too Dispenser verification protects you twice. It guards against a penalty, and against the slow loss a drifting meter causes every shift. Keep the verification date for each dispenser, not for the station as a whole. Before the inspector leaves, check that the next date is on the calendar. ## 05 The monthly check Once a month, read the register from top to bottom. Anything that expires within ninety days gets a status, an owner and a next step. It takes ten minutes, and the year-end audit stops being a search. ## 06 How Octyn does it Octyn's compliance module holds the register, with each document's expiry and the scanned copy. It tracks dispenser calibration alongside it. Expiries within the window raise an alert on the owner dashboard, "licence expiring", with the days remaining. So the reminder does not depend on anyone opening a spreadsheet. See it with your own documents: [request a demo](/contact-us).
