Know what each document proves

Your booking, payment, tax and custody records serve different purposes.

Four records, four questions

RecordWhat it establishes
Booking confirmationThe agreed supplier, service, price and references
Payment acknowledgmentThe payment the supplier has verified and allocated
Tax invoiceThe applicable transaction document issued by the right entity
Collection receiptThe boxes physically handed over and recorded condition

Keep the identifiers connected

A booking can include several boxes. The collection receipt should identify each one, while the payment record should connect to the correct booking. A later delivery acknowledgment should be traceable to the same physical box.

Check changes in writing

If a box is added, a price changes or a payment remains unallocated, ask for an updated record. Keep earlier versions where they explain what changed. A social-message screenshot is useful context but should not replace the supplier’s actual transaction and handover records.
