Retainers buy capacity and priority; projects buy a defined outcome. Mixing them without labeling creates “unlimited work for fixed price” by accident.
When each model fits
Ongoing needs—content, ads ops, community moderation—suit retainers with hour or output caps. One-off builds—site launch, brand sprint—suit milestones and acceptance criteria.
Predictable monthly revenue reduces anxiety; projects can pay faster lump sums. Track trailing three-month average, not single good months.
Scoping retainers: caps and rollover
Specify included hours or deliverables, response times, meeting cadence, and whether unused hours expire. “Unlimited requests” is a trap unless priced like it.
Project fees: milestones and change orders
Split deposits, mid-project, and final on acceptance. Define review rounds. Anything new becomes a written change order—friendly but firm.
Numbers to track
- Effective hourly rate per engagement.
- Scope creep hours donated monthly.
- Utilization vs bench time.
Transitioning clients
Explain the benefit in their language: faster turnaround, strategic bandwidth, or clearer accounting. Give a start date and sample monthly calendar.
Price the maintenance, not only the launch.
Raises on new work first
Grandfather loyal clients selectively; new quotes reflect current skill and demand. Document the policy so you do not negotiate against yourself.
