Ensure that there is constant communication between you and the custom essay writer. If they have live chats or instant messaging, this is ideal. However, check upfront to confirm if this level of communication is possible.
Custom essay writing services should have 24/7 customer support. You need to communicate with the company to know the progress of your order. Check of all the communication channels are working. A reliable service should respond promptly to your questions.
You probably would like to read the writing before paying for it, wouldn’t you? And if you are unsatisfied with the work, you have a right to ask to edit it. Clients are the priority in such services, so you should be also offered a front page, outline, reference list and structuring at no charge.
Some of those sites employ non-native speakers and writers without university degrees and that might impact on the quality of their works. To avoid this, read as much custom reviews as possible. You can also check the requirements for applying on the service as a freelance writer.
Remember that you have enlisted their services. In other words, they are working for you. Their work is an investment in which you have put money, and you deserve good returns. They should give you a free title page, formatting, outline, and bibliography.
