# Receiving gas

> Record gas tankers by weighbridge ticket or tank gauge, buy gas by the kg from suppliers, claim for short deliveries, and log full cylinders in and empties out.

Gas comes in two ways: in bulk, by tanker into a gas tank, and in full cylinders from a plant or supplier. Both are recorded on the daily sheet of the day they arrive. A gas tanker works like a fuel tanker, in kg instead of litres: what the supplier says it loaded (the waybill), what actually came in, and a supplier claim when it's short.

## Buying gas

In **Purchases**, an owner or admin records gas bought from a supplier like fuel: choose **LPG**, the kg and the cost per kg. Gasos works out the total. Gas is offered only where Gas is turned on, and a purchase for a station needs Gas on there.

Each tanker received against the purchase counts towards it, so the purchase shows how many kg have arrived and stays under **Awaiting delivery** until they all have. Purchase exports show gas in kg.

## Recording a gas tanker

In the **Deliveries** section of the sheet, press **Record a delivery** and choose **Gas tanker**. (A gas plant's sheet has Deliveries for its gas tankers too.) Fill in:

* **Purchase** (optional): the gas purchase it's against.
* **Supplier**, **truck number**, **driver** and the **seals**.
* **Waybill number**, and the **kg on the waybill**: what the supplier says it loaded.
* **The gas tank** it went into.

Then record what came in, one of two ways:

* **Weighbridge ticket**: the ticket number, the **gross** weight (the truck full) and the **tare** (the truck empty), and a photo of the ticket. What came in is the net: gross − tare. The gross must be more than the tare, and the net can't be more than the tank holds. One ticket weighs one truck into one tank.
* **Tank gauge**: the tank's gauge before the gas goes in and after, as a percentage or in kg like the closing gauge, and any gas sold from the tank in between. What came in is after − before, plus what was sold in between.

<Note>
  A weighed tanker needs a photo of its ticket before the sheet goes in; a gauged one needs a photo of the waybill.
</Note>

## Short deliveries and claims

When what came in is less than the waybill by more than the station's delivery allowance (in **Station setup → Rules**, the same as fuel's, 0.3% by default), Gasos asks for a reason and opens a **supplier claim**. Record what the driver said.

An owner or admin settles the claim from the delivery, the **Stock** page or **Purchases** once the supplier credits or replaces the gas, with a note of how. Settling and reopening are kept in the activity log. Open claims show on **Today** under **Needs attention**, and say how many are for gas.

## Gas tank stock

What a tanker brought adds to the tank's **book stock**: opening + received − kg sold. Tonight's gauge is checked against it, with the gas tank allowance (see [Gas on the daily sheet](/gas/gas-on-the-daily-sheet)). If more came in than the tank can hold, Gasos warns you to check the ticket or the gauge readings.

## Full cylinders in, empties out

Under **Cylinders in and out** in the Gas section, record:

* **Full received**: the size, how many, who they came from (a supplier, or someone else in words), the waybill number and a photo.
* **Empties sent**: the size, how many, who they went to for refilling, and a reference.

Only sizes the station keeps can come in or go out: full ones in where it keeps full ones, empties out where it keeps empties. To change a count, type the new number; **Remove** asks first. They complete the cylinder book that tonight's count is checked against:

* **Full**: opening + received − exchanged.
* **Empty**: opening + exchanged − sent.

More empties sent than there were stops the sheet going in until it's corrected. See [Cylinder exchange](/gas/cylinder-exchange) for the count at close.

## Where it shows

* **Stock** page: gas tankers are in the **Deliveries** list in kg, with the ticket number, filtered with **Gas**. Open one for the ticket's gross, tare and net, the photos and the claim. The CSV export shows gas in kg.
* **Suppliers**: a supplier's page lists its gas deliveries with the kg received, and the full cylinders it sent.
* **Today**: the **Gas sold** column notes the kg received that day.
* **Reports**: **Deliveries and shortages** has gas sections, by supplier and tanker by tanker, in kg.
* The daily summary lists gas received and the cylinders received and sent.
