The hidden cost of multi-quarter retainers

Long retainers feel like commitment. They are also a way to dilute the urgency that makes consulting work valuable in the first place.

When the engagement length is open, the energy of the first month tends to spread across many months. Decisions that should have been made in week three drift into the second quarter. The team that hired the consultancy gets used to having them around; the consultancy gets used to the relationship; nobody has the awkward conversation about whether the work is still serving its purpose.

We have come to believe that consulting works best when there is a defined deliverable, a defined timeline, and a real ending. When the consultant knows the engagement closes on a specific date, the pace of decisions matches that date. When the client knows the consultant leaves on that date, the urgency of internalising the work matches it too.

This is not a universal claim — programme delivery, for example, often genuinely needs longer engagements. But for strategy and advisory work, we have found ourselves declining proposals for multi-quarter retainers in favour of shorter, sharper engagements that close cleanly.

The clients who come back for a second engagement tend to come back for a different problem, on a similar shape of engagement. The clients who would have been on a retainer often do better as occasional advisory rather than permanent capacity.
