Service fees are applied in conjunction with the cost of the arrangements, and are dependent on the number of arrangements you have. Your first invoice will usually be higher than your following monthly invoices. These fees cover labor and overhead. They will also be applied to your account each time you order a new design, or if your current arrangement(s) are taken back to the shop for maintenance.
For events, clients with more than 5 arrangements, and large or elaborate displays, discussion is necessary. An onsite visit is required before starting a project for clients, to access the environment, and to view the space for dimensions and to better help me create an arrangement that fits the clients decor.
