Hourly vs Project Pricing: Which Should You Put on Your Invoice?

How you price determines what your invoice looks like and, more importantly, how easy it is to get paid without an argument. There's no universally right answer, but there are good reasons to choose one over the other for a given job.

Hourly pricing

You bill for the time you spend.

Good for:

• Undefined or changing scope ("help us with our marketing")
• Ongoing support and maintenance
• Work where the client controls the pace (lots of meetings, feedback rounds)
• Early in your career, while you learn how long things take

Downsides:

• Your income is capped by your hours
• You're penalized for getting faster
• Clients may watch the clock and question every hour
• Hard for clients to budget

On the invoice: hours, rate, and a description of what the time was spent on. See invoicing for hours worked.

Project (fixed) pricing

You agree a price for a defined outcome.

Good for:

• Well-defined deliverables (a logo, a 5-page website, a bathroom refit)
• Work you've done many times and can estimate accurately
• Clients who need a fixed budget

Downsides:

• You carry the risk if it takes longer
• Scope creep eats margin unless you control it
• Needs a clear scope in writing

On the invoice: the deliverable or milestone, not the hours. Listing hours on a fixed-price invoice invites the client to judge the price by the time.

Hybrids that work

Fixed price with a change rate. A fixed price for the defined scope, plus an hourly rate for anything outside it, agreed in writing before it's done:

Website build as per proposal: $6,000. Additional work outside the agreed scope: $90/hour, approved in writing in advance.

Capped hourly ("not to exceed"). You bill hourly, but agree a maximum. Clients like the budget certainty; you should like it only if the scope is well understood.

Day rates. Common for photographers, consultants and trades. Simpler than hourly, with less clock-watching.

Retainers. A fixed monthly fee for a defined amount of availability or work. See retainer invoices.

Value-based pricing. Price tied to the value to the client rather than your time. Works best for experienced specialists with measurable impact, and still ends up on the invoice as a project fee.

Choosing, job by job

Ask:

1. Can I define the deliverable clearly? If not, hourly or capped hourly.
2. Have I done this exact kind of job before? If yes, project pricing is likely to be more profitable.
3. Does the client need budget certainty? If yes, project or capped hourly.
4. How much will the client change their mind? A lot: hourly, or project with a firm change process.

Raising rates

Whatever model you use, review your rates at least once a year. Give existing clients notice (30–60 days is courteous) and apply the new rate from a specific date. Your invoices should simply show the new rate from then on; no special wording is needed beyond the heads-up you gave in advance.
