Do interior designers charge retainers?

Often yes. A retainer reserves the designer and is applied against future fees or purchases. Confirm whether it is refundable and how unused amounts are handled.

Is flat-fee design better than hourly?

Flat fees create predictability for defined scopes. Hourly can suit evolving projects but requires clear reporting. Ask which revisions are included.

Do designers earn commission on furniture?

Some use trade pricing plus a procurement fee or markup. Others bill design time separately and pass through product cost. Get the model in writing.

What should an interior design proposal include?

Scope rooms, deliverables, timeline, number of concepts/revisions, site visits, purchasing responsibilities, and payment schedule.
