Where allowance money actually moves
Coverage boundaries cause the first surprises. A fixture allowance may cover the faucet but not the valve behind it; a tile allowance may cover material but not the upgraded setting work a large format demands. Ask what related costs live outside each allowance, because the boundary lines are where totals grow without any line visibly changing.
Quantity assumptions cause the second wave. Allowances price an assumed amount, area of tile with a waste factor, a count of fixtures, and your selection can change consumption: larger formats change cuts and waste, patterns add quantity, a heavier product adds handling. Overage math should adjust quantity and price transparently, and the assumed quantities belong in writing at signing.
Credits deserve equal rigor. Selecting below an allowance should return the difference by the documented markup rules, not vanish into the project. How a professional handles allowance credits, cheerfully and in writing, or vaguely and reluctantly, is one of the cleaner honesty signals available before you have to trust them with a bigger one.
