After your quote is approved by a customer, they can place an order. When they do, you'll receive an email notification and you'll need to acknowledge the order before sending a proof.
Acknowledging an order indicates to a customer that you will produce the item based on the the specs, terms, deadlines, and pricing in the quote.
After an order is acknowledged, you should upload a proof for the customer's approval.
After they approve the proof, upfront payments are initiated and you should start production.
When reviewing the order, if any specs, deadlines, logistics, or other details are different than what you initially quoted, or you'd like to change some details of the order, you can click the Decline button from the order's page.
You should list a reason that you're declining the order with clear next steps so that the customer can quickly update and resend the order.
