What happens to a tracked product's quantity on hand when it is added to a project?

When a tracked product's quantity on hand is added to a project, it remains unchanged until invoiced. This reflects the fact that the inventory count does not decrease at the moment the product is assigned to a project since it’s still technically available for sale until the transaction is finalized through invoicing.

Typically, the process in accounting and inventory management allows a company to maintain visibility of available stock until a formal sale is recorded. In this case, the system tracks project management and inventory separately until a customer transaction occurs, thus ensuring that the inventory levels are accurately reflected for both projects and sales activities. Once the invoicing happens, the quantity on hand will adjust to account for the sale and the project's resource consumption.
