# How your stock updates itself

You don't change stock counts by hand. Receiving a purchase order adds stock, starting a make order or recording a week of production uses the ingredients and packaging and adds what you made, and shipping a sales order takes the products out.

## What changes your stock

| When you… | Stock does this |
|---|---|
| Receive a purchase order (**Received all**, **Received some**, or **Receive All** on the list) | Each line becomes a lot in stock, dated the day you received it |
| Click **Start Production** on a make order | The ingredients and packaging come out of stock |
| Finish each task on the make order | What you made goes into stock as a batch |
| Click **Record This Week** on a weekly production log | The ingredients and packaging come out, and the products go in |
| Mark a sales order **Shipped** | The products come out, the soonest-to-expire first |
| Click **Start Packing** on a transport order | The products and shipping materials for every stop come out |

Marking a transport order **Delivered** marks its sales orders **Shipped**. Their products came out at packing, so they aren't taken twice.

Saving a purchase order or a make order doesn't change stock yet. It shows what's coming, with the date you expect it.

## Will there be enough?

Sales orders, transport orders and make orders show a chip beside each item:

- **In stock**: you have enough.
- **Exp. Mar 3**: you're short now, but a purchase order or make order due that day covers it. With no date it says **Expect stock**.
- **Need stock**: nothing on order covers it yet.

On the **Sales Orders** list, stock that earlier orders are already counting on isn't counted twice, so the chip tells you whether this order can actually go out.

## Used more than you entered?

Prophitable lets the order or the week go ahead. When you start a make order or record a week, it first lists anything you're short of. Then it records what was used before it was entered, and the next stock you add pays it back first.

> [!TIP]
> Because every order moves stock for you, the count stays right as long as orders go through Prophitable. When you count the shelf and the number is different, that difference is worth knowing about. Often it's waste, a spill or a sample nobody wrote down.
