The booking summary (the screen where you can press claim) will have all the details of what is included in the task. The Poster will expect you to complete everything listed there.
Airtasker is a strong believer in fair pay, and we advise Posters to double check their booking summary to make sure all the required information is there. If a Poster requires something else not listed in their booking summary, we’d suggest negotiating a price increase.
Remember, when you’re assigned to a one-off Instant Claimable, it becomes a normal task with normal task functions. That means you can private message, request a price increase, receive bonuses, and get reviews as you usually would.
