Should I charge hourly or a flat project fee as a freelancer?
Use a flat fee when you know the job well enough to estimate it with confidence, and use hourly when the scope is genuinely unclear or likely to shift. A flat fee gives the client price certainty and lets you earn more per hour if you work efficiently, but you carry the risk if you underestimate. Hourly protects you from scope that grows, but puts the uncertainty about the total cost on the client instead.
Neither model wins by default. It comes down to how well you actually know the job in front of you. Know the scope, flat fee is usually the right call. Scope is unclear or likely to move, hourly protects you better.
Flat fee, when you know the job
If you've done this type of project before, or you can break it into concrete deliverables you can estimate the hours for with reasonable confidence, charge a flat fee. The client gets certainty, they know the total cost before they say yes, and you get to keep the upside: if you're faster than planned, you earn more per hour than you estimated. The flip side is yours to own too. Underestimate the hours and you're the one eating the difference, not the client.
Hourly, when the scope is unclear or will move
Research-heavy work, iterative design processes, or a client who's genuinely still figuring out what they want are hard to price flat honestly, because you'd be quoting a number you don't actually have the basis for. Hourly fixes that: you get paid for the time you actually spend, no matter how much the scope grows along the way. The tradeoff is that the client carries the uncertainty about the final total, which can make some clients more hesitant to say yes up front.
A middle ground: flat fee with a cap on extra hours
You don't have to pick one model for the whole project. A flat fee based on an estimated number of hours, with a clear line between what's included and what counts as extra work billed hourly on top, gives the client the same price certainty as a flat fee without leaving you exposed to the full risk if the project grows beyond what you scoped.
Still unsure? Split the project
If you can't tell whether the scope is clear enough for a flat fee, that's often a sign the project itself is too big or too loosely defined to price as one block. Break it into smaller, better-defined pieces instead. Put a flat fee on the parts you can see clearly, and leave the rest hourly or estimated until it's scoped out too.
Steadytrack's proposal flow lets you set up both in the same proposal, a flat fee on what's defined and an hourly rate or estimate on what isn't, so you don't have to force the whole project into one pricing model just to send it.
