Background
Payments in the construction industry work in a different way to the more traditional payment structure, with payments staggered over time as work is completed, reductions in the amount paid held back for various reasons, and a portion of the final amount held back for a period of 12-24 months depending on the terms agreed, to cover any defects. The sub-contractor will usually submit an “Application for Payment” to the Quantity Surveyor who will then review this and make any adjustments accordingly for any works not completed and apply any discounts or retentions applicable. The Sub-contractor will then submit an invoice for the agreed amount. The Purchase Order needs to be created showing all of the deductions, the invoice logged, and then the payment is issued to the sub-contractor. The nature of the payments, being drawn out over time against an agreed overall amount, results in the need for a payment certificate to be issued with each payment which notes in detail exactly what is being paid out in this period, what has been paid out in the previous period, as well as the total paid out overall, plus any deductions which have been made and any retentions (amount held back for the defects period) which have been held. There is often CIS Tax deducted from the payment as well. This information goes out in what is known as a Sub-Contractor Payment Certificate.
