Delivery problems usually start with vague contracts. Before work begins, nail down exactly what you're delivering, when, and how many revision rounds are included. Clear terms prevent misunderstandings later.
If you are struggling with delivery today, go back and check your contract. Was there some misunderstanding between you and the client about what is to be delivered, about the timeline? You're thinking you'll deliver in a month, they want it in a week. But potentially, if you're doing something creative, maybe design, or you write content, how many iterations, how many different cycles of feedback is included? All of that, if you take care of it during sales, you will not suffer during delivery.
