Hello,

There is inventory accounting option in system settings. You can choose as you need. If you need more details about FIFO, LIFO or AVCO, you can check the documenation.pdf

Yes, you will need to update the price if you selling price is changed. For purchase cost, you just need to choose the method.

FAQ from docs below

Can you please explain Inventory Accounting (FIFO/LIFO/AVCO)?

First-in-first-out (FIFO)

Defined: The oldest inventory asset is recorded as sold first – regardless of the actual shelf-age of the given physical asset.

Applied: While it is the most widely used accounting technique in periodic inventory management today, FIFO may fail to offer a full picture of inventory value if inflation and price increases are not closely analyzed. Thus, FIFO may inflate or deflate the actual value of future inventory.

Last-in first-out (LIFO)

Defined: The newest inventory asset is recorded as sold first.

Applied: The LIFO method could reduce a company’s tax responsibility in times of growing inflation – but it has been heavily regulated under the International Financial Reporting Standards.

Average cost or weighted cost (AVCO)

Defined: The AVCO (average cost) method will take the total cost of goods still available for sale and divide it by the total sum of product from the beginning inventory and purchases.

Applied: With the AVCO method, cost flow is determined as a weighted average of all total unit costs.

Thank you

This method is for cost. But the selling price for all stocks increases. What if we want to sell previous stock at previous price?

Hello,

You can sell at whatever price you want. Set it on item then system will use that. Once want to change, edit the item.

Thank you
