# Design Retainer

> An ongoing engagement where a client reserves a set amount of design capacity each month, rather than paying per fixed-scope project.

A design retainer reserves a recurring block of a team's capacity — a certain number of hours or a defined output — for a flat monthly fee. It trades the rigid boundaries of project work for flexibility: priorities can shift week to week as the product's needs change.

Retainers fit ongoing, evolving work far better than fixed-scope contracts, which is why they underpin the [embedded team](https://www.themasterly.com/glossary/embedded-design-team) and [team extension](https://www.themasterly.com/services/team-extension) models. They also smooth cost and guarantee availability — the design partner is there when a fast-moving startup needs them, not queued behind a new statement of work.

## In practice

A startup reserves a monthly block of design capacity. In January it goes to the onboarding redesign; in February, a fundraise pivots everything to the pitch deck and data-room materials; March splits between marketing pages and design-system cleanup. No new scoping call, no change orders — priorities shift inside the reserved capacity. For a company whose needs change weekly, that flexibility is the product; the hours are just the unit.

## FAQ

**When does a retainer beat a fixed-scope project?**

When the work is continuous and priorities shift — ongoing product design, growth iterations, brand upkeep. Fixed scope fits one-off, well-defined deliverables like a single site or an audit.

**What happens if we don't use the capacity one month?**

Depends on the agreement — good retainers allow partial rollover or flex months. In practice, product companies almost never run out of design work; the backlog problem is the opposite one.
