When you are invited to a Request, you are able to ask the Buyer questions. The Buyer can then reply to this question. Their reply can either be public (so all suppliers can see the answer) or private (so only you can see the answer). If the answer is made public, your name and details will not be included with the question.
When viewing a Request, you will see a '? icon' to the right. Click this icon to send a question to the buyer.
Once you click the '? icon', you will see a text box pop up. You can type your question here and click the 'Ask this question' button to send it to the Buyer. Any questions you have asked them previously (for this Request) will also appear here, under the ‘Questions you’ve asked’ heading.
When your question is answered, you will be sent an email with the Buyer's answer. You will also be able to view the answer when looking at the request details.
