01
Agree on the return terms first
Contact the supplier before repacking or dispatching material. Confirm which pieces are eligible, required packaging, transport arrangements, and any inspection or credit conditions. Keep the original order number and product labels. Do not assume that unused slate can automatically be returned under the same terms as another building product.
02
Close the inventory loop
Record the quantity dispatched, the supplier's receipt, and the final accepted credit or other resolution. Update the project inventory so returned pieces are no longer counted as repair spares. If the return concerns a disputed condition, retain the relevant photographs and correspondence. Clear records help prevent a later shortage from being blamed on material that was intentionally sent back.
