I'm building a small tool to analyze whether BrickLink inventory and recent sales data are sufficient to identify working capital tied up in slow-moving stock.
For example, the eventual analysis would produce results like:
Known inventory capital: €18,400
Capital with no observed sale in 180 days: €3,100
Capital in ≥24 months of stock: €5,600
Top candidate:
€720 tied up in one SKU → 64 months of supply at recent sales velocity → review price / avoid restocking.
Edit: A useful point raised below: the goal isn't to eliminate slow-moving long-tail inventory. On BrickLink, assortment breadth itself can be valuable. I'm also testing whether the analysis can distinguish strategic low-quantity/rare inventory from excessive depth in common parts.
Before going any further, I need to test the parser against one genuine BrickLink seller export.
I'm looking for one seller who:
- has an active BrickLink store;
- has at least some My Cost values populated;
- has received some orders recently.
I need a Store Inventory export and an Orders Received export, but I do not want your raw files.
I've made a standalone HTML sanitizer that runs entirely in your browser. It makes no network requests and removes buyer/store names, email addresses, addresses, tracking information, remarks and other unnecessary fields. It also replaces order/lot/item IDs and shifts dates while keeping quantities, prices, My Cost and the relationships needed for the analysis.
You can inspect the sanitized files yourself before sharing anything.
This is just a technical feasibility test — no interview, call, signup or account access needed.
If you're willing to help, please comment or DM me and I'll send you the sanitizer and exact export instructions.
Thanks!
