Different moving companies follow different payment terms and it varies from case to case. There is no fixed formula. Some of the moving companies may charge full payment in advance and other may offer 70:30 or 8:20 payment terms, which means, 70% or 80% of the agreed quotation value have to be paid before departure and remaining 30% or 20% at the time of delivery. You can always negotiate the payment terms with the moving company you are working with. But avoid making full payment in advance.
