Service & Pricing Models

Hourly Pricing vs Percentage of Ad Spend

In short: Neither model is tied to results. Hourly ties the fee to time worked, so efficiency reduces what the provider earns. A percentage ties it to your media budget, so spending more increases what they earn. Both have a known incentive problem, and both are managed with structure rather than with trust.

Hourly Pricing

Bills for time actually worked at an agreed rate, so the cost varies month to month according to the hours logged.

Time-based billing at a stated rate, usually tracked against timesheets or a prepaid block of hours. It fits short engagements, audits, training, and scopes nobody can size in advance. The drawbacks are administration and incentives: efficiency reduces the provider's revenue, and buyers end up scrutinizing hours instead of results, so cap the hours or move to a fixed scope once work stabilizes.

Percentage of Ad Spend

Charges the management fee as a share of the advertising budget, so what you pay rises and falls with how much you spend.

Fees scale with media budget, which ties cost to account size and lets small accounts start cheaply. The known criticism is incentive: the manager earns more when you spend more, even in months when spending less would be the correct call. The fair counter-argument is that scaling spend does create real additional work. Tiered rates, spend caps, and efficiency targets are common mitigations.

Side by side.

The differences that actually change what happens in your account.

	Hourly Pricing	Percentage of Ad Spend
Fee tied to	Hours logged	Media budget
Predictability	Varies with the month's workload	Varies with the month's spend
Incentive risk	Speed reduces revenue	Higher budgets increase revenue
Small accounts	Cheap if the work is genuinely light	Starts small and grows with the account
Administration	Time tracking and reconciliation	Read the spend, apply the rate
Usual mitigation	Prepaid blocks or capped hours	Tiered rates, a cap, efficiency targets

What actually separates them.

Hourly prices the input of time, while a percentage prices the size of the media budget, and neither prices the result.

Hourly makes cost transparent and effort visible; a percentage removes timesheets entirely at the cost of tying fees to budget decisions.

The percentage model's criticism is that recommending a cut costs the provider revenue, with the fair counter that scaling really does create more work.

Hourly gives you a hard cap by simply not approving more hours, whereas capping a percentage takes an explicit contract term.

Because neither is outcome-linked, both need a separate written agreement on how performance will be judged.

Which one should you use?

Use Hourly Pricing when

The work cannot be sized in advance, such as an inherited account of unknown condition.
You need occasional help rather than continuous management.
The engagement is a bounded audit, migration, or training block.
You want a hard ceiling by buying a fixed block of hours.

Use Percentage of Ad Spend when

The account needs continuous management and you do not want to review timesheets.
Spend is small now but expected to grow, and you want fees that start proportionate.
Seasonality means you want fees to fall in quiet months as well as rise in busy ones.
Workload genuinely tracks budget across more campaigns, markets, and creative.

Common questions.

Which incentive problem is worse?

They are different rather than ranked. Hourly rewards slowness and penalizes a provider who solves something quickly. A percentage rewards budget growth even in months when spending less is correct. Which one bites depends on whether your realistic risk is padded hours or over-spending, and both are contained by structure rather than goodwill.

Can I use both in one relationship?

Yes, and it is a reasonable split. Bounded projects such as an audit, a migration, or a rebuild go hourly or on a fixed quote, while ongoing management runs on a percentage or a fixed monthly fee. Keeping them separate stops project work quietly disappearing inside a management fee.

How do I judge either arrangement?

Against the account and the business, not the invoice format. Ask for a change log alongside the results, and check that the work applied matches what was billed for. Then judge outcomes over a full sales cycle, because pricing model tells you how you pay and nothing at all about whether the work is good.

Or stop choosing between them.
