When to use
Use this when scoping a fixed-fee web design or development project and you want to avoid underpricing. Best for projects in the $10k–$150k range where you've gathered enough discovery info to estimate hours. Run it before drafting the SOW.
The prompt
You are an agency operations lead who has scoped and priced 100+ fixed-fee website builds for digital agencies, including Webflow, WordPress, Shopify, and custom Next.js builds.

Agency: [AGENCY_NAME] | Project type: [PROJECT_TYPE]
Platform: [PLATFORM] | Estimated pages/templates: [PAGE_COUNT]
Key functionality: [FUNCTIONALITY]
Integrations: [INTEGRATIONS]
Design starting point: [DESIGN_STATUS]
Content: [CONTENT_STATUS]
Timeline: [TIMELINE]
Internal blended cost/hr: [COST_BASIS]
Target gross margin: [MARGIN_TARGET]
Risk factors: [RISK_FACTORS]

Produce a fixed-fee project price with a transparent build-up: estimated hours by role, total cost, risk buffer, margin applied, final price, and a recommended payment schedule.

- Use only the hours, rates, and scope I provided — do not invent numbers.
- Add a risk buffer of 10-25% based on the [RISK_FACTORS] I listed; justify the % chosen.
- Margin must hit [MARGIN_TARGET]; show the math.
- Flag any scope items that should be excluded or moved to phase 2.
- Recommend a 3- or 4-stage payment schedule tied to milestones.

1. Hours table: Role | Hours | Internal Cost
2. Cost build-up: Subtotal → Risk Buffer → Margin → Final Fixed Price
3. Scope exclusions (bullets)
4. Payment schedule table: Milestone | % | Amount
5. One-paragraph rationale to share internally
Variables
  • [AGENCY_NAME] — Your agency
  • [PROJECT_TYPE] — Marketing site, ecommerce, web app, etc.

  • [FUNCTIONALITY] — Forms, gating, search, calculators, etc.
  • [INTEGRATIONS] — HubSpot, Salesforce, Klaviyo, Stripe, etc.
  • [DESIGN_STATUS] — From scratch, redesign, existing brand
  • [CONTENT_STATUS] — Client-provided, agency-written, mixed
  • [TIMELINE] — Weeks to launch
  • [COST_BASIS] — Blended internal cost per hour
  • [MARGIN_TARGET] — Gross margin target
  • [RISK_FACTORS] — Unknowns, stakeholder count, dependencies
Example input
AGENCY_NAME: Lighthouse Studio | PROJECT_TYPE: B2B SaaS marketing site redesign | PLATFORM: Webflow | PAGE_COUNT: 18 templates, 35 pages | FUNCTIONALITY: HubSpot forms, gated content, blog | INTEGRATIONS: HubSpot, Segment | DESIGN_STATUS: New design from existing brand | CONTENT_STATUS: Client-provided, we polish | TIMELINE: 12 weeks | COST_BASIS: $85/hr | MARGIN_TARGET: 50% | RISK_FACTORS: 4 stakeholders, no signed brand guide
Example output
Hours: Strategy 24h ($2,040) | Design 90h ($7,650) | Webflow Dev 140h ($11,900) | QA 24h ($2,040) | PM 40h ($3,400) — Subtotal: $27,030
Risk buffer: 18% (no brand guide + 4 stakeholders) = $4,865
Cost basis: $31,895 → Apply 50% margin → Final Fixed Price: $63,790
Exclusions: Net-new logo, custom illustration, SEO migration mapping (phase 2).
Payment schedule: 30% kickoff ($19,137) | 30% design approval ($19,137) | 30% staging review ($19,137) | 10% launch ($6,379).
Rationale: Stakeholder count is the biggest risk; we built buffer for two extra design rounds.
Pro tips
  • If the risk buffer pushes price above the client's range, cut scope — don't cut buffer.
  • Tie payments to client deliverables (approvals), not just calendar dates, to keep projects moving.
  • Save the cost build-up internally; share only the final fee with the client unless they push back.
