Stop giving single-number estimates — the intake habit that protects a freelance project's margin
"It's basically a simple marketing site, maybe a contact form. What would you charge?"
Every freelancer has answered this with a number. And every freelancer has watched that number become a ceiling on a project that turned out to be twice the size. The mistake isn't the price — it's quoting from the client's summary instead of from extracted requirements. Here's the intake habit that fixes it, before you say a figure.
1. Extract requirements, and tag each one
Read the brief (email thread, call notes, voice memo) and pull out every concrete requirement. Tag each as [explicit] (the client actually said it) or [inferred] (you're assuming it). "A contact form" is explicit. "...that emails them and stores submissions and has spam protection and a thank-you page" is four inferred requirements hiding inside it. Inferred items are where scope quietly doubles.
2. Write the out-of-scope list first
Before the estimate, write down what you are not doing: no CMS, no multi-language, no account system, content provided by the client, two rounds of revisions then hourly. The out-of-scope list is your single best margin protector — it's what you point to in week three when "can we just add…" arrives. If it doesn't exist before the quote, it can't defend you later.
3. Turn every hole into a forwardable question
Anywhere the brief is ambiguous, don't assume — write a question the client can answer verbatim: "Will you provide final copy, or should we budget copywriting?" "Do you need to edit the site yourselves after launch?" Each answer either removes risk or legitimately expands scope (at a price). Send these before the number.
4. Quote a range, never a point
Give a range with a ~1.5× ceiling, and state the assumptions it rests on: "$X–$1.5X, assuming you provide copy and we use an off-the-shelf form." A single number says "I have certainty I don't have." A range prices the uncertainty honestly — and clients respect it more, not less. Always include testing and deployment as explicit line items; they're real hours.
The whole move is: the out-of-scope list and the questions exist before the number does. That one ordering change is the difference between a profitable project and a death-march.
