The hidden cost nobody budgets for: the gaps between suppliers

You collect quotes. Florist, caterer, band, photographer, hire company. Each one is clear, itemised and reasonable. You add them up, and the number works.

Then the real number arrives four months later, eight to fifteen per cent higher, and nobody can quite say where it came from. It came from the gaps.

What a gap looks like

Every supplier quotes their own scope precisely and stops at its edge. What falls between two scopes belongs to nobody, and it becomes yours.

• The florist quotes the arrangements. The plinths they sit on are hire.
• The band quotes the performance. The stage, the power distribution and the supplier meals are not in it.
• The caterer quotes per head. Cake cutting, extra staff hours past midnight, and the bar spend after the package hours are separate lines.
• The hire company delivers to the loading dock. Carrying it into the room is labour, charged by the hour.
• The venue includes the room. Not the cleaning after a confetti moment, which is a bond deduction.

None of this is anybody behaving badly. Each quote is honest about what it covers. The problem is that nobody is looking at the whole.

The four gaps that cost the most

Labour on either end. Bump-in and bump-out are where budgets quietly go. Ask every supplier what their delivery includes, and specifically whether it includes carrying, positioning and collection.

Power and rigging. Lighting, band, photo booth, catering equipment and coffee cart all need power. Venues have a finite number of circuits. Discovering this on the day means hiring a generator at emergency rates.

Supplier meals. Fifteen suppliers on site for eight hours need feeding, and most contracts require it. At the catering rate that is a real line, and it is almost never in anyone's first budget.

The last hour. Extensions are priced per hour, per supplier, and they are decided at 11pm when saying no is hardest. Decide the finish time in advance and price the extension before the night, not during it.

How to find them before they find you

Put every quote side by side and read only the exclusions. Write a single list of everything that appears in nobody's scope. That list is your real contingency, and it is usually between eight and fifteen per cent.

Eighteen years of doing this in Melbourne means Stuey mostly knows where the gaps sit before the quotes arrive, which is the actual value of experience — not knowing better suppliers, but knowing what none of them are quoting for.
