Service & Pricing Models

Flat Fee vs Hourly Pricing: Fixed Scope or Billed Time

In short: A flat fee prices a defined piece of work and puts estimation risk on the provider. Hourly prices the time and puts that risk on you. Fixed scope is better when the work can be described precisely; hourly is better when nobody can honestly size it in advance, such as an inherited account of unknown condition.

Flat Fee

Charges one fixed price for a defined piece of work or service level, quoted up front regardless of hours worked or media spend.

A single agreed price for a specified deliverable or service tier, such as an account build, a campaign launch, or a monthly package. Buyers get certainty and providers are rewarded for working efficiently, which suits well-bounded work. The failure mode is scope creep in both directions: when the work outgrows what the quote assumed, either quality slips or the arrangement needs repricing.

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.

Side by side.

The differences that actually change what happens in your account.

	Flat Fee	Hourly Pricing
What is priced	A defined deliverable	Time actually worked
Who carries estimation risk	The provider	You
Predictability	One number, known in advance	Varies with how the work unfolds
Provider incentive	Finish efficiently	Efficiency reduces revenue
Administration	Scoping up front, then little	Time tracking, approvals, reconciliation
Best fit	Builds, migrations, audits, launches	Unknown scopes and intermittent support

What actually separates them.

A flat fee transfers estimation risk to the provider, which is why an uncertain scope is quoted with a buffer.

Hourly transfers that risk back to you, and in exchange the price reflects only the work that actually happened.

Fixed pricing rewards efficiency while hourly penalizes it, which matters most on repeatable work a provider has done many times.

Hourly costs more administration on both sides, so arrangements usually convert to fixed scope once the work becomes predictable.

Both need the same protection: a written definition of what is included and a process for handling what turns up unexpectedly.

Which one should you use?

Use Flat Fee when

The deliverable can be described precisely, such as a build, migration, or audit.
You need one number for budget approval.
You would rather not review timesheets or approve incremental hours.
The work is repeatable for the provider, so their estimate is well grounded.

Use Hourly Pricing when

The scope is genuinely unknown, such as a neglected account nobody has opened in months.
You want exploratory diagnosis before committing to a defined project.
Support is occasional and you only want to pay when you use it.
You want a hard cap through a prepaid block, with the option to stop at any point.

Common questions.

Which one ends up cheaper?

It depends on how well the work can be estimated. Fixed quotes include a buffer for uncertainty: small when the job is familiar and repeatable, large when the provider is pricing the unknown. Hourly removes that buffer but exposes you to a longer job than expected, so the answer follows how predictable the work really is.

How do I move from hourly to a flat fee?

Run hourly through discovery and the first phase, then use what you learned to define a fixed scope for the rest. That sequence prices the uncertainty honestly instead of guessing at it, and it gives both sides real evidence about how long the work takes in your account rather than in general.

What protects me on a flat-fee engagement?

Written inclusions and exclusions, a stated number of revision rounds, an explicit assumption list covering the account's condition, and a named change-order process with an approver. Most disputes come from discoveries nobody priced rather than bad faith, so the assumptions section is the part worth spending time on.

Or stop choosing between them.
