These are all great answers. They are right, if the timer started just get the job done quick, so you have it when the buyer responds. Sometimes people don’t come right back to Fiverr if they have gave all the info.
If you’re missing info, I would reach out again. After the 3rd time in a 24 hour period, I would ask customers service to cancel with the reason buyer not responding. The buyer will see the notice and usually respond. If they don’t answer within 3 days of the cancellation notice the job automatically gets cancelled.
You won’t earn your money but the job won’t be counted against you either.
It terms of finding work, challenge yourself to exhaust your 10 daily offers in the Buyers Request. Someone is almost always looking to get work done, so you’re basically practicing your pitch. If there aren’t many buyer request in your category, open up other gigs in different categories you fit into, so you can see the work that is being requested in those categories.
