An inventory is especially important for insurance purposes. When you make an insurance claim for damaged, lost, or stolen property, your insurance policy will require you to show the quantity, description, and possibly the amount of loss associated with each item. You may also be asked to provide copies of bills, receipts, or other documentation to support your figures. If you omit some items or fail to include an adequate description of others, you may receive less than full compensation for your losses. Relying solely on your memory can be an expensive mistake.
