How do we stop a retainer drifting into busywork?

Agree the indicators in week one and review them monthly. If the retainer can't be described in terms of what it should move, it's the wrong model for that work. That's usually a sign it's actually project work.

What about hourly billing?

We don't use it. Hourly rewards slowness and turns every conversation into a billing question. It suits truly unpredictable advisory work and almost nothing else in marketing execution.

Can one engagement use both?

Commonly, and it's often the cleanest structure. A fixed-scope build to get the asset in place, then a retainer to run and improve it. That way each part of the work sits in the model that fits it.

By Mara Delgado, Managing Partner

Retainers reward continuity. Projects reward finishing.

Each model creates a different incentive, and matching the model to the work matters more than negotiating the rate.

Our bias, declared

We use both and we're not indifferent between them. Retainers suit work that is truly ongoing, like campaigns, content and testing, where the output is a steady rate, not a single deliverable. Projects suit work with an end state, like a site build or a rebrand. Putting project work on a retainer is how engagements drift. Putting ongoing work on a project is how they end abruptly with nothing maintained.

Side by side

Retainer vs project pricing comparison
Factor	Retainer	Fixed-scope project
Best suited to	Ongoing work with no end state	Defined deliverable with a finish line
Budget predictability	High, same amount every month	High, agreed upfront
Scope flexibility	High, priorities shift monthly	Low, changes need a change order
Incentive to finish	Weak, continuing is the default	Strong, payment is tied to completion
Incentive to over-scope upfront	Low	High, agencies pad fixed bids
Speed to start	Fast, no detailed scoping	Slower, scoping takes time
Accountability for outcomes	Depends on agreed indicators	Tied to a specific deliverable
Ease of exit	Notice period, clean	Awkward mid-project
Risk if the estimate was wrong	Shared, scope adjusts	Agency absorbs it

Choose retainer when

The work truly has no end

Campaign management, content production, and testing programs are rates of output, not deliverables. Scoping them as projects means re-contracting every quarter for no benefit.

Priorities will change

If what matters most in month three is unknowable in month one, a retainer lets you redirect without a change order. Projects punish that.

You want continuity of team

Retainers keep the same people on your account. Project work releases them at the end, and the next project starts with new people relearning your business.

Speed to start matters

Retainers skip detailed scoping. If you need work beginning next week, that's often decisive.

Choose fixed-scope project when

There's a clear finished state

A website, a rebrand, an audit, a migration. These end. Paying monthly for them creates no urgency to reach the end.

You want the estimate risk on the agency

Fixed scope means if the work takes longer than quoted, that's the agency's problem. That's a genuine transfer of risk and worth paying for.

Budget approval is per-initiative

Many organizations can approve a capital project more easily than an ongoing operating cost. The model should fit how your finance function actually works.

You're testing a new agency

A defined project is a far better trial than a retainer. You see the work, the process, and how they handle problems, with a natural exit.

It can be, and that's the honest risk. The protections are short notice periods, agreed leading indicators reviewed monthly, and no annual lock-in. If an agency resists all three, the retainer is about their revenue, not your work.
