Before you can upload an invoice for your services/goods, you need to accept the order by agreeing to buyer’s standard purchasing terms.
You should accept the order right away, and upload your invoice only when the payment is due.
Please be aware that if you don’t accept the order for too long, the buyer will be notified by the system and this may result in cancelling the order.

To accept the order, sign in to your Candex account and select the relevant order on your left panel.
Click Review & Accept Terms to view the standard purchasing terms of the buyer.
Once you agree to the terms the buyer will be notified that you have accepted the order and will provide them with the service/goods they ordered from you.
