Stock

What you have, what it cost on average and what is running low. Every delivery, count and correction goes in a ledger per item, and a batch logged from the lye calculator takes what it used.

Average cost is the weighted average of what you paid, recalculated with each delivery. A batch takes stock out at the average.

How it works

An item linked to an ingredient is where a batch takes that ingredient from. Log a batch on the lye calculator and its oils, lye and additives come off the shelf; anything not in your stock is listed rather than refused. Undo puts it all back.

Each delivery moves the average cost per gram by weight, the way the accounting standard for inventories describes it. Using stock does not move it. A delivery into stock that has gone below zero sets the price on its own, and stock added without a cost is taken to have cost what the next delivery did.

Lots are traced oldest first: each batch is taken to have used the oldest delivery still on the shelf, which is how stock is usually rotated. Where you name the lot a batch used, that comes first. Stock used before its delivery was recorded is traced to that delivery and marked as such. The cost is still the weighted average; the order only decides which lot went where.

IAS 2 Inventories, paragraphs 25 and 27, as adopted in the EU by Commission Regulation (EU) 2023/1803: the cost of interchangeable inventories is assigned by the first-in, first-out or the weighted average cost formula, and under the weighted average "the average may be calculated on a periodic basis, or as each additional shipment is received". This recalculates it as each shipment is received.

IAS 2 Inventories, paragraph 27, as adopted in the EU by Commission Regulation (EU) 2023/1803: "The FIFO formula assumes that the items of inventory that were purchased or produced first are sold first, and consequently the items remaining in inventory at the end of the period are those most recently purchased or produced." IAS 2 uses it to assign cost. This uses the same assumption only to say which delivery a batch most likely drew from; cost stays the weighted average.
