Petroleum products are typically delivered to the warehouse in large vessels such as IBCs and Skids. The products may be decanted into smaller vessels. The original lots and batches are tracked. Unused residue is accounted for and can be written-off.

Serialised IBCs, Skids and other shipping types are tracked to every customer.

Since these types of products are usually accounted using litres or kilograms, reports show total units (e.g. cartons) and total contents (e.g. litres).
