Appropriate method to work Inventories

[Toby]

Hi,

I am trying to use Beancount to track inventories and I am a little confused on how to do this correctly. I understand that there is costs and pricing and that @@ is used to denote price (which can change) and {{}} which the cost and can't change.

Let me explain here :-

2021-01-01 * "Purchase Some Supplies"

    Assets:Inventory:Banana                10 PCS  {{30 USD}}

    Assets:Inventory:Apple                   2 PCS     {{50 USD}}

    Assets:inventory:Orange                3 PCS      {{20 USD}}

    Assets:Cash                                     100.00 USD

 

Or :-

2021-01-01 * "Purchase Some Supplies"

    Assets:Inventory:Banana                10 PCS  @@ 30 USD

    Assets:Inventory:Apple                   2 PCS   @@ 50 USD

    Assets:inventory:Orange                3 PCS    @@ 20 USD

    Assets:Cash                                     100.00 USD

 

I often get weird output when working with commodities (they are always getting revalued) and the numbers don't add up. I have tried multiple things such as :-

2021-01-01 * "Purchase Some Supplies"

    Assets:Inventory:Banana                30 USD  {{10 PCS}}

    Assets:Inventory:Apple                   50 USD {{2 PCS}}

    Assets:inventory:Orange                20 USD  {{3 PCS }}

    Assets:Cash                                     100.00 USD

The above seems to fix the valuation problem (commodities don't get revalued) but its a little complicated. Is there any guides on how to work with commodities?

Thanks

Yes, there's extensive documentation:

https://beancount.github.io/docs/how_inventories_work.html

https://beancount.github.io/docs/trading_with_beancount.html

I suggest reading and understanding those, and avoiding the @@ and {{ notations, at least at the beginning. Use @ and {} instead.

If you have specific problems, send us an output of your query, what you expect, and what you get.

Hope that helps!
