Fellow reader here. (Astrologer)
When someone orders a Gig (reading) from you, you type it up in whatever document writer you have (I use Libre Office) and then you save it to your computer as a PDF file. ALWAYS use the DELIVER NOW green button on the ORDER page to deliver your readings. When you press the Deliver Now button, a box will pop up which will have a link within it to attach your files you have saved on your computer. Do that, then in the box itself, write a nice note to the buyer and thank them for choosing you to do their reading. (Or whatever it is you want to say) DO NOT ask the buyer to give you a review - this is against the TOS (which you should take time to read, since you did agree to it when you made your Gigs) and can get your account a warning or worse, get you banned. Never discuss reviews with buyers, NEVER. Got that? OK.
ALWAYS make sure that the buyer has placed an order BEFORE you do any work! If you have a potential buyer message you through the messaging system here, that is NOT them placing an order - that is just a message, and many newbies here have fallen into the trap of doing the work and delivering through the message box instead of waiting for the client to order - you will see on your Dashboard page when someone has ordered from you or you can see your orders from the menu on the top of your dashboard page.
If you make a Custom Offer for a buyer within the message box, NEVER start work on that reading until the buyer ACCEPTS the Custom Offer and the order goes to your orders page. Some newbies here also fall into this trap then wonder what the heck went wrong!
If you want to offer revisions or follow up questions about your reading, limit them to 1 or 2 - NOT unlimited. I do not and have not offered ANY revisions in all the time I have been here (since 2013).
Anything else, ask on the forum and I am sure you will get help.
