What are common mistakes in retainer agreements?

The most common mistakes in retainer agreements are a missing scope cap, silent rollover rules, and no exit clause. A retainer without a monthly hour or deliverable cap becomes unlimited work for fixed pay. Unused hours with no rollover policy become a client dispute in month three.

Other frequent gaps: no payment date, no rate for work beyond scope, no notice period for ending the arrangement, and nothing about what happens to fees already paid.

When you review one, look for those five items first. They decide almost every retainer disagreement. The fix is cheap: state the cap, the rollover rule, the overflow rate, and a 30-day exit in plain sentences before anyone signs.
