How to stage the payment in practice
The cleanest way to run a moving payment is to treat each stage as a gate that opens only when the work behind it is done. At booking, pay the token advance to a company account and get the GST invoice that names the advance and the balance. Do not let a verbal promise stand in for that invoice, because the invoice is what makes every later stage enforceable. On move day, release the post-loading share only after the goods are actually packed and on the truck, not when the crew arrives, since paying before loading hands over your bargaining power for nothing.
At the new home, hold the final balance until you have walked the rooms and checked the fragile items and the appliances. This is the moment the delivery-linked balance earns its place: if a TV is cracked or a carton is missing, the unpaid balance is what gets it resolved quickly rather than through weeks of calls. Pay the balance once you are satisfied, take a final receipt, and keep the whole thread, the quote, the invoice and the payment proofs, in one place.
For an intercity move the same logic stretches across more days, so the three-part split matters even more: the truck is out of your sight for the transit, and the held balance is your assurance that it arrives and is handed over properly. Whatever the move length, the rule does not change. A small token to start, payment that tracks the work, and a real balance tied to a clean delivery is the structure that keeps your money safe and the mover motivated to finish the job well.
