The Gas Stock Guard: Never Sell Gas You Do Not Have

The pain: paper stock that lies

Here is a quiet disaster that happens in gas businesses everywhere. The notebook says the tank should still hold 60kg. An attendant sells 20kg, then another 25kg, then 30kg. Nobody notices that the paper total has now gone below zero, because nobody is adding it up in real time. Weeks later the records claim you sold 75kg out of a tank that only had 60kg in it.

What does that mean? It means at least one of your numbers is a lie. Maybe a refill was never recorded. Maybe sales were invented or duplicated. Maybe stock was measured wrongly from the start. Whatever the cause, the moment your recorded sales exceed your recorded stock, every downstream number, cost, profit, shortage, becomes fiction. And fiction is exactly what you cannot take to a lender, a partner or your own planning.

Paper cannot stop this, because paper does not do arithmetic. An app can.

What the stock guard is

Gazeloft's Gas space keeps a live count of your stock in kg, fed by two flows: refills add kg in, sales take kg out (costed by FIFO from the oldest batch, as covered in Article 2). The hard stock guard is a simple, strict rule sitting on top:

The app will not let you record a sale for more kg than your recorded stock actually holds.

Not a warning you can swipe past. A hard stop. If your recorded stock is 14kg and someone tries to record a 20kg sale, the entry is refused. This single rule guarantees something powerful: your books can never claim you sold gas that, according to those same books, did not exist. An empty tank can never be oversold on paper.

The guard is not there to embarrass anyone. It is there to catch a mismatch at the exact moment it appears, when it is still easy to fix, instead of at month end when nobody remembers anything.

Step by step: living with the guard in the app

  1. Keep refills current. The guard is only as accurate as your refill entries. Record every bulk purchase the day it arrives, with kg and cost. This is the habit that makes the guard your friend instead of your obstacle.
  2. Sell normally. For everyday sales you will never see the guard. It only appears when recorded stock is about to be exceeded.
  3. When the guard blocks a sale, stop and think. There are only three possibilities: the tank truly is nearly empty (time to reorder), a refill was not recorded (record it now, with the correct backdate if needed), or earlier entries were wrong (investigate before adding more).
  4. Fix the cause, not the symptom. If the missing piece is Thursday's unrecorded refill, enter it with Thursday's date using the backdating field. FIFO order stays correct and the blocked sale now goes through.
  5. Use stocktake for physical differences. If the recorded stock says 30kg but the gauge says 22kg, that is a shortage, and Article 5 covers exactly how Gazeloft books it honestly.

Step by step: on the web dashboard

The guard is enforced by the Gazeloft backend, not by one device, so it applies identically on gazeloft.com. A worker on the phone and the owner on the web dashboard are both held to the same live stock figure. The web dashboard also shows your current stock position at a glance, which makes it easy to check remaining kg each evening and plan the next refill before the guard ever needs to intervene.

A worked example: the Tuesday the guard earned its keep

Kabiru runs a gas station in Kano with one attendant, Sani. Recorded stock on Monday night: 47kg from a batch bought at ₦1,180 per kg.

Tuesday is busy. Sani records sales of 12.5kg, 6kg, 12.5kg and 10kg: 41kg gone, 6kg remaining on record. At 3pm a customer arrives with a 12.5kg cylinder. Sani enters the sale and Gazeloft refuses it: recorded stock is 6kg.

Sani calls Kabiru. It turns out Monday evening's 250kg refill from the new depot (₦295,000, ₦1,180 per kg) was delivered while Sani was closing up, and nobody entered it. Kabiru records the refill from the web dashboard, backdated to Monday, while still at the market. Thirty seconds later Sani's sale goes through, costed correctly against the new batch.

Now consider the counterfactual. Without the guard, Sani would have kept selling all week. By Friday the books would show perhaps 160kg sold from a recorded 47kg, and the unrecorded ₦295,000 refill would look, to the cash ledger, like ₦295,000 that simply vanished. Untangling that at month end could take an evening and still leave doubt. The guard turned it into a thirty-second fix on Tuesday afternoon.

The numbers stayed honest too: the week's 160kg of sales at ₦1,400 per kg produced revenue of ₦224,000 against a true cost of ₦188,800, a clean profit of ₦35,200 that Kabiru can actually believe.

Tips and pitfalls

  • Never work around the guard with fake refills. Entering an invented refill just to force a sale through poisons your batch costs and your Refills report. Find the real missing entry instead.
  • Check remaining kg every evening. Recorded stock versus the tank gauge is a ten-second glance that catches drift early.
  • The guard cannot see leaks. It compares sales against recorded stock. Physical losses like leakage or theft reduce the tank but not the record; the stocktake feature exists to reconcile that difference.
  • Reorder using the record. When recorded stock drops below your usual two or three busy days of sales, order the next refill. The guard should be a safety net you never actually hit.
  • Backdate missing refills to their true date. FIFO draws costs in date order, so a refill entered late but dated correctly keeps every sale's cost accurate.

A record you can defend

The stock guard is one strict rule with a big payoff: your gas books can never contradict themselves. Combined with FIFO batches and honest stocktakes, it gives you numbers you can defend to anyone, including yourself. Free to start, no card needed. Stop guessing. Start seeing, at gazeloft.com.

Frequently asked questions

A customer is standing in front of me and the guard is blocking the sale. What do I do?

Serve the customer, then fix the record straight away: enter the missing refill (backdated if needed) and record the sale. The guard is telling you a refill entry is missing, and it will pass the sale the moment stock exists.

Does the guard work offline?

Yes. Offline entries are validated against stock, and the sync process keeps everything consistent when the connection returns.

Can the owner override the guard?

No one can sell beyond recorded stock, owner or worker. That strictness is exactly what makes the numbers trustworthy.

What if my scale and the app disagree slightly?

Small physical differences accumulate as shortage. Run a stocktake; Gazeloft books the missing kg honestly as stock loss without touching your selling profit.

Does the guard slow down my sales entry?

Not at all. It does no extra work on normal sales. It only appears when something is genuinely wrong.
