Inventory is an asset, so if you want to account for inventory in this example, you would record two debits and two credits:

- $5 debit to cash (asset => debit means +5)

- $5 credit to revenue (equity => credit means + 5)

- $X debit to cost of goods sold (liability => debit means - X)

- $X credit to inventory (asset => credits mean - X)

Where X is the cost of the materials that went into the lemonade. So if X < 5, you made a profit. In terms of the equation, this comes out to:

    Assets = Liabilities + Equities
    (5 - X) = (-X) + (5)

So it all adds up to 0, but you make a (gross) profit or loss depending on the value of X.

You wouldn't account for the customer's side of things because the customer is not on your books.
