Keep a clear handover.

The person collecting may not be the person serving. Make sure the actual instructions and ingredient information travel with the cake. A photo of the agreed order note can help keep the practical record together.

Make the plan while it is fresh.

Add your questions to the brief before the order is confirmed.
