A product has a cost of materials you can point to. A service is mostly your time, your expertise, and things that are genuinely harder to put a number on — which is exactly why so many service-based quotes end up underpriced.
Start from your actual hourly cost, not a guess
Work out what an hour of your time genuinely needs to cover — not just take-home pay, but software, insurance, admin time, and the slow weeks between projects. Guessing a "fair sounding" rate without this math is how service providers quietly underprice themselves for years.
Estimate time honestly, including the parts that aren't billable-feeling
Revisions, client calls, and project management time are real hours spent on the project, even if they don't feel like "the work" itself. Leaving them out of your estimate is one of the most common ways a quoted project ends up costing you more than it earns.
Price the outcome, not just the hours, where you can
For experienced service providers, value-based pricing — charging based on the result for the client rather than strictly hours spent — often earns more than hourly billing, especially for work with a clear, measurable business impact for the client.
Build in a buffer for scope creep
Service projects drift more than product orders — a "quick logo tweak" becomes three rounds of revisions. Either price in a reasonable buffer or state clearly in the quote what's included and what counts as additional work.
Don't be the cheapest option by accident
A quote that's dramatically lower than a competitor's for the same scope of work sometimes reads as inexperience rather than good value, especially for professional services — pricing too low can cost you the job as easily as pricing too high.
