The same 3-part form can be used for special orders as for repairs. You can add multiple inventory items to the order, including slush skus(non-inventory charges added to orders). When you add a special order you can automatically take a deposit. And, when you sell the special order the deposit or deposits will automatically be applied to the balance due. And, as with repairs, when the order is ready a text and/or email can be sent to the customer telling them that the job is ready.
