Number the container first
A moving inventory works best when it follows the physical packing. Give each box a unique identifier before filling it, and place the same identifier on more than one visible side. If the moving company supplies its own numbers, keep the two systems connected rather than treating them as separate inventories.
Write down the destination room, a short description of the main contents and any priority information. “B12, kitchen, everyday plates and blue mugs, open early” is easier to use than either “Kitchen” or an exhaustive list of every spoon.
Use specific descriptions for items that could be mistaken for one another. “Children's books” may be sufficient for one box; six such boxes need a little more distinction. Descriptions such as “bedtime shelf” or “school reference books” reflect how you will look for them later.
Photograph what the words cannot describe
A photograph before a box is closed can show its arrangement and contents quickly. Photograph the identifier too, or name the image so it matches the inventory. A folder full of unnamed box photographs creates another sorting task on arrival.
For an object with several parts, record where the small pieces are packed. Attach or securely bag the hardware in an appropriate way, following the mover's advice for the item, and describe the location. “Shelf brackets in B18” prevents opening unrelated boxes to search for them.
Keep any information needed for the moving company's own process in the format it requests. A household list can sit alongside formal paperwork, but it should not be assumed to replace it or prove a claim by itself.
Update at the point of change
Boxes often change contents during the last days. Cross out or update the entry when that happens, rather than trusting someone to remember. If a box is reopened and split, give the new container its own identifier.
Store a copy of the inventory where it remains accessible during travel. On delivery, use a separate received marker and note anything that needs following up. Do not erase the original packing description while checking boxes in.
After unpacking, the inventory has done its job. Keep relevant records for as long as your circumstances require, but do not feel obliged to maintain a permanent database of everyday belongings. Its purpose was to get the household from one place to another with less searching.
