Cost of goods

Moss

Hi ATUM team,

We’re currently running a WooCommerce setup with Cost of Goods for WooCommerce Pro by WPFactory for handling purchase prices, and ATUM as our inventory management tool.

Our setup and workflow:

We manage stock centrally with ATUM and manually update stock levels when new items are received.
We enter product quantities variation-by-variation when new shipments arrive.
The standard purchase price for most products is consistent, but occasionally our supplier offers discounts, which gives us a lower cost price for certain batches.

The challenge:

When we receive discounted stock, we’d like to reflect that lower cost in our records without overwriting the standard cost of goods set in the product data. Simply changing the cost of goods temporarily for the product or variation creates inaccurate reporting because it affects all products sold during that period — not just the discounted batch.

We’d prefer to:

Add incoming quantities in ATUM (ideally through the Purchase Orders module or Stock Central),
Enter the actual purchase price for that particular batch,
And have the system average the cost of goods over time based on quantities and their individual purchase prices.

Our questions:

Is there currently a way in ATUM to add stock quantities with their respective purchase cost (without overriding the base cost in product data)?
If not, is this something achievable through the Purchase Orders module or a custom extension?
Are there any best practices or integrations between ATUM and WPFactory’s Cost of Goods Pro that support this kind of stock + cost tracking?

Looking forward to your insights or recommendations!

Thanks in advance,
Kevin

Hi Moss

ATUM only supports its own purchase price field.
If you need to add support for that 3rd party plugin, it will require custom development.

And replying to your questions:

Is there currently a way in ATUM to add stock quantities with their respective purchase cost (without overriding the base cost in product data)?

With Purchase Orders (free and PRO), you can add stock quantities by default.
And you can also update purchase prices from a PO. But the ATUM field, not others.

If not, is this something achievable through the Purchase Orders module or a custom extension?

If you need to handle multiple purchase prices (and also prices and sale prices) for a batch of items of the same product, you can achieve this with Multi-Inventory.
But we don't have any functionality to have the "system average the cost of goods over time based on quantities and their individual purchase prices" as you mentioned. This would require custom development.

Are there any best practices or integrations between ATUM and WPFactory’s Cost of Goods Pro that support this kind of stock + cost tracking?

The best practices are the same as any WordPress development. But if you need to integrate both, you will need a developer to assist you.
If you don't have one and need an estimate for the integration, please open a private ticket, and we can discuss it.

Bets Regards,
Salva.

Hi Salva,

Thanks for your response.

Currently checking the trial version off the Purchase Orders Pro addon. There we can set a different price for a product. You can replace the current price but couldn't find the option to average out the price. Example purchased 10 for $500 and 10 for $450 it shows 20 for $475. Is it possible to make this happen?

The Cost of Goods plugin should have a tool to read the prices of the Atum purchase prices. This did not work when I tested it out before but that is up to them to make that happen. The step above is necessary though.

Kind regards,
Kevin

If you read my previous message, I said:
