Definition

An allowance for the supply of a particular item that has not yet been selected, with associated labour, waste, delivery and mark-up treated as the quote states.

Why it matters

The allowance needs a clear scope and adjustment method so a later selection can be priced fairly.

Example in practice

The quote carries a £35/m² PC sum for tile supply and prices fixing labour separately.

Use the term carefully

State whether the allowance is supply only and how labour, waste, delivery and mark-up will be treated when the selection changes.
