OUR SERVICE CHARTER







  • Better Grades Guarantee

    Our team of writers prides in high-level competence. The writers have the required expertise that enables them to deliver quality papers that match with the requirements of the grading rubric. In the absence of the rubric, we ensure that the writers follow the clients’ instruction brief to the letter. We can confidently assure our clients to expect nothing short of a pass from the papers that we deliver. Importantly, we have qualified writers who handle different areas of study. This diversification enables us to allot clients’ orders to the writer who is well seasoned in the subject area of study. It also enables the team to become more professional due to specialization. Our clients should put their trust in our service delivery and expect to successfully attain high grades at all times. The fact that we offer free revision reflects our dedication in delivering high quality papers that match with our clients’ expectations.
  • Free Revisions

    The papers that we deliver usually reflect a high quality level. However, there is always a room for any additional fine-tuning touch in line with a client’s preference without any additional charges. To begin with, a client has discretion to make a choice on their preferred top writer from our team. Such a writer could have handled past work for the client and received a positive review from the same. It means that the client has confidence of the quality of service that the writer delivers. Secondly, a client has an option of making use of our editing services. Our editors are always on standby to revise the paper and ensure that it matches with the expectations of a client that the instruction brief had detailed. The revision covers content adjustment that removes off-topic details, addition of sources, removal of language style errors, and assessment of the referencing style in order to enhance compliance.
  • Excellent Quality Work

    Grammar is one of the elements that we take seriously in our service delivery. Beside the use of spell checkers, we progressively take our writers through the essentials of a quality paper that features information clarity. Importantly, we encourage our writers to avoid coming up with a paper that deviates from the elements that appear on the client’s instruction brief. It means that the papers that we deliver denote well researched information that is rich in details. Additionally, the papers usually contain exhaustive details on any instruction that a client submitted. It is the tireless application of our writers’ efforts that makes us stand out when it comes to the delivery of excellent quality work. Notably, our writers use quality resources when digging up information that a paper requires. They are usually aware of the sources that contain rich information. Our past clients have proved that we give nothing short of quality work through giving us a positive feedback.
  • Money Back Guarantee

    If any of our writers deliver an incomplete or ambiguous paper that is off the topic, our clients can claim for a refund in regard to the oversight. We do not compromise our service delivery through submission of a paper that does not follow our clients’ instructions. We also mind about the interest of our customers, and we always give them value for their money. However, our clients have a choice to request for a free revision within 14-30 days, or depending on the length of the submitted paper. A client who needs a refund should send a request for it within 14 days after receiving the completed paper. If a client decides not to download the paper, then they can request for 100% refund. Any refunded amount usually goes to the client’s Bonus Balance as store credit. There is always extra compensation when the refund takes the form of store credit. Alternatively, the refunded amount can also go the client’s credit card.
