Build the expected list
Start with kit ID, item ID, description, expected quantity, observed quantity and note. Fictional kit K7 lists one machine M, one hose H, two extension pieces E and one floor attachment F. The expected total is five physical pieces, across four item rows. Do not count the storage bag as part of that total unless it has its own row. Photograph references may help identify items, but a picture does not establish compatibility or working condition.
