Ray Carnes:

The cost of the products in the moment of the purchase should not be taken to analize revenue, That is completely wrong unless you have no other choise, which means that you are not integrating your inventory with your accounting, but Odoo already does that.

If you purchase product X specifically for Customer Y for Project Z then it is fine to use the cost, as that is the product you are giving them. You statement relates to using Purchase Orders for products that won't be guaranteed to ship to the Customer.

We have a lot of products which are not specifically purchased for a customer / sales order.

One type of our products is purchased in large quantities and sold as needed.

Other products are raw materials which are used to produce sellable products.

In both cases we need the cost of these products in the analytic account.

You can also review the margin for products in other ways - if you check on "Margins - show margins on orders" in Sales you can then turn on the margin and cost fields and see both on every order - if you check or "Margin Analysis - Monitor your product margins from invoices" in Accounting you get the "Product Margins" report.

If your company purchase for a specific customer/project, there is still no guarantee that the customer will buy them all or that a total consumption will be achieve, you must consider scrapped products or delivery issues for instance. What you are stating means that the COGS, valuation methods and IFRS are not needed.

Companies use "analytics accounts" because it is the only feature that fits for the set up of their business lines, business units, projects (among others) and because in the end what they need is to meassure their profitability. So it is a serious matter that the COGS are not automatically integrated with the analytic accounts, specially since you already have them linked in the sales orders.

Ray Carnes:

We don't need margins for products. We need to analyse our sales / projects.

We need to keep track of all the costs accumulating on a project.

We have costs from working hours in office and on site and record these costs in the analytic account of the sale / project via time tracking.

We have costs from buying products specifically for one products. Selecting an analytic account for products in incoming invoice registers these costs on the analytic account of this sale / project.

And, like I said, we have products in stock for direct usage in different sales or for production of sellable products. And we need to keep track of the costs of these products used for sales / projects.
