Define 'done' before you start
Most scope disputes are not disagreements about effort — they are disagreements about what was promised. The checklist forces a written definition of done: exact deliverables, file formats, number of pages or assets, and what explicitly is not included.
Anything left ambiguous will be interpreted in the client's favour, because the client is the one who benefits from a wider reading.
Revision counts and change orders
The checklist asks you to state a revision limit and what happens past it. Two rounds included, further rounds at an hourly rate, is a normal, defensible arrangement that clients accept when it appears before work begins.
Change orders do not need to be elaborate. A two-line email confirming the new request, its price and its effect on the timeline is enough to protect both sides.
开工前先定义“完成”
多数范围争议不是关于投入多少，而是关于当初承诺了什么。清单强制你写下“完成”的定义：具体交付物、文件格式、页面或素材数量，以及明确不包含的内容。
任何含糊之处都会按有利于客户的方式解释，因为放宽解读的受益方是客户。
修改轮数与变更单
清单要求你写明修改轮数上限，以及超出后的处理方式。包含两轮修改、之后按小时计费，是客户在开工前看到就能接受的常规安排。
变更单不需要复杂。一封两行邮件确认新增请求、价格与对排期的影响，就足以保护双方。
