How hourly pricing works
With hourly pricing, your invoice is generally based on tracked or agreed working time multiplied by your hourly rate. It can be useful when requirements may change, the work is exploratory, or the client needs ongoing support.
The main planning challenge is estimating how many hours you can actually sell. Use a realistic billable-hours estimate rather than assuming all working time is client time.
How project pricing works
With fixed project pricing, you estimate the work and quote one agreed amount for the defined scope. This can make budgeting easier for a client, but it means your estimate needs to account for the time required to deliver the agreed result.
Build a project estimate from an hourly rate
A simple starting formula is:
(Project hours + revision hours) × hourly rate + expenses
You can then add a contingency percentage if the scope has reasonable uncertainty.
Worked example
Suppose your benchmark is $75 per hour, the project needs 20 production hours, revisions need 3 hours, and expenses are $100.
Labor = (20 + 3) × $75 = $1,725.
Before contingency, the project estimate is $1,725 + $100 = $1,825. A 10% contingency would bring the planning estimate to $2,007.50.
What to include in a fixed-price scope
- Deliverables and formats.
- What is explicitly outside the scope.
- Number of revision rounds or a revision assumption.
- Client responsibilities and required inputs.
- Timeline and milestones.
- Payment schedule and due dates.
Common pricing mistakes
- Quoting only production time and ignoring meetings or revisions.
- Accepting an open-ended scope at a fixed price.
- Adding a large discount without checking the effect on your effective rate.
- Failing to state what happens when the client requests additional work.
Which model fits a project?
The answer depends on scope, uncertainty, client expectations, and how you prefer to manage risk. The useful first step is to understand the numbers behind both models rather than treating one pricing method as universally appropriate.
