Interior design proposal pricing language for flat fees.

A flat fee should not land in the proposal as a lonely number. The client needs to understand what the fee covers, why the payment timing exists, and how extra work will be handled if the project changes.

Simple flat-fee paragraph

The flat design fee for this room package is based on the agreed scope, deliverables, project complexity, estimated design time, communication, presentation work, and revision allowance. This fee keeps the design process clear and predictable while giving us a defined framework for the work included.

Deposit paragraph

To reserve the project start and begin design work, a deposit is due at approval. The remaining balance is due according to the milestones listed in this proposal. Work begins after the deposit is received.

Change-order paragraph

If the project expands beyond the approved scope, additional work will be quoted before it begins. This includes additional rooms, extra revision rounds, new design directions, added sourcing, contractor coordination, purchasing support, or implementation work not listed in the original scope.

Why clear language helps the sale

Clear pricing language makes the fee feel more professional. It also gives the client a clean next step: approve the scope, pay the deposit, and begin. A vague proposal invites negotiation because the client has to guess what the number means.
