# Stock Adjustments Most of the time, you’ll be getting stock into your Pakk account through placing and receiving Purchase Orders. Likewise, outgoing stock will mostly be via dispatching Sales Orders. There are times, though, when you’ll need to make manual adjustments to stock levels, like in the following circumstances: * Getting your starting stock onto the system when first setting up Pakk (opening adjustment) * Disposing of damaged stock * Disposing of expired stock * Moving stock from one batch to another, for example between locations * Adjusting for picking errors * Readjusting stock after a stocktake * Accounting for stock given away as samples * Creating stock out of a combination of other stockable items (assembly builds) ### Adjust Lots, Not Products Remember that all stock in Pakk is tracked via Lots. Lots represent a way to control stock at a more granular level than the Product level. Lots allow you to achieve results like: * Tracking expiry dates for different Lots * Tracking location of different Lots of the same Product * Tracking different financial valuations for Lots * Serial numbers or similar single-item tracking If you don’t need any of that functionality, you can just create a single ‘ALL’ Lot for a Product and use it for all your stock of that SKU. Stock Adjustments always adjust Lot stock, not Product stock - therefore all Stock Adjustment lines need a Lot assigned. If you are adjusting existing stock, this won’t be a problem because it will already ‘live’ inside a Lot, so you’ll just select that Lot. However, if you are creating new stock and don’t want to assign it to an existing Lot, or if there isn’t an existing Lot, you’ll have to create a new Lot first. Stock Adjustment lines can either be positive (stock increases) or negative (stock decreases). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
