|---|---|
| Saying yes without repeating the terms | Restate price, scope, and start date so both sides agree |
| Accepting by phone with nothing in writing | Always follow up with a written acceptance letter |
| Hiding conditions in small print | Name every condition plainly in the body of the letter |
| Forgetting to name a contact or a start date | End every acceptance with a name, a date, and a next step |
