Practical guidance for organizing inventory, tracking sets, counting stock, preparing imports, and identifying parts.
Storage & inventory
A useful parts inventory connects a quantity to a place you can find. Give each storage location a stable name, record what belongs there, and update the record when pieces move.

Collecting
Two copies of the same set do not always have the same missing pieces. Give each physical copy its own record, then note its location, condition, and missing parts.

Storage & inventory
A piece can be on the shelf and still be spoken for. On-hand inventory records the stock you have. Available inventory accounts for commitments that prevent you from using or selling some of it.

Collecting
A photo can narrow the search for an unfamiliar part, but the result still needs checking. Isolate the piece, make its shape easy to see, and compare the returned candidates with the object in your hand.

Storage & inventory
A useful count is a defined snapshot, not a quick guess at a total. Use this checklist to set the boundary, count physical stock, review differences, preserve the correction record, and recheck a small sample.

Collecting
A small, normalized CSV can save retyping when you have several set copies to add. Use the exact two-column format, preview the whole batch, fix every problem, and confirm only when the resulting set copies look right.

Collecting
See the difference between what a list needs, what you have on hand, and what a list actually claims before you count pieces as free for a build.
