Forum_Admin I am very sorry, but this feature is not yet possible in ATUM.
We plan to add it as a premium feature in 2020.
I agree with impreza54. The ability to track serial numbers is going to be a critical feature for a lot of customers looking at more advanced inventory management for WooCommerce.
For my example, I bring in used computer hard drives, run them through a testing system, which outputs the results of testing and wiping them to a database we created. We're recording their serial numbers and a bunch of other information about the hard drives. Ideally we want to then add to our inventory, those hard drives that passed the tests, and leave off those that failed. I don't expect this level of integration, but just explaining what we're doing and why we need serial number tracking.
Today, we track serial numbers sold in a Google Spreadsheet, and tie the order number to it. What we want, is the ability to do this all within WooCommerce. If we have an order in the system, we want to be able to edit the order, add serial numbers to line items, and then complete the order. So we'd need a way to track which products in WooCommerce will have serial numbers, and then an option to force serial number entries for each quantity sold of that product before allowing the order to be completed. That way we always have serial numbers recorded if we have the option set to require it for products flagged as having a serial number.
We sell some products that don't have serial numbers, so obviously we don't want to be forced to record a serial number for a product that doesn't have one.
This way from a product support perspective, we can easily search and determine if the serial number is one we sold them right within WooCommerce. On the customer side of things, it would be great for them to be able to login to their account to see their purchase history, and see their serial numbers for themselves, along with any warranty period info tied to the product based on when it was shipped out and the default warranty we provide for that product.
I haven't downloaded your free version yet, I'm just in the research phases of trying to find something that does what we're looking for, or close to it, so then my website developer can attempt to integrate a system like yours with our own database of products we're testing, and have everything update automatically as we sell through the list of serial numbers we've tested.
I would fully expect this to be a premium feature, and would love to be a part of helping you guys map out the development cycle for it, along with testing it if you're serious about adding this feature to your list of premium options.
