What this planner helps you decide

Best for

Consultants, agencies and service businesses preparing a fixed-fee project quote.

Outputs

Protected delivery cost, quote before indirect tax and best, base and worst-hours comparisons.

Start here

Break the work into delivery tasks, then add direct costs, contingency and target margin.

Use a different tool when: Do not use this to set a viable rate and project quote; use Service Rate & Quote Planner for that decision. Use this tool to turn scoped task rows and project costs into a transparent fixed quote.

Decision pack · Step 2 of 5

Quote to Cash

Connect a viable service rate to a scoped quote, realised job margin, collection cost and short-term cash forecast.

  1. 1. Set the service rate
  2. 2. Build the project quote
  3. 3. Review realised margin
  4. 4. Price the collection delay
  5. 5. Forecast short-term cash

Current decision: What price protects the scope, contingency and delivery margin?

Next: Compare the approved quote with actual delivery economics.

Project Quote Builder: protected delivery cost

Treat the quote as a protected commercial starting point, then reconcile it with scope, exclusions and client value.

Formula summary

Primary formula
quote ex indirect tax = protected project cost ÷ (1 − target delivery margin)

Read the full methodology

Data used here

  • The estimate uses your inputs and the general business formula documented in the methodology.

Decision checks

Act on the result

Move the base quote into a written proposal that states delivery scope, revision limits, contingency and approval terms.

Stress-test the decision

Review the worst-hours scenario and increase contingency where scope, dependencies or client approvals remain uncertain.

When this estimate can be misleading

  • This builds a commercial scenario, not a contract, invoice or legal scope document.
  • Task effort, internal rates, costs, contingency and margin are your assumptions; no market benchmark is used.
  • It excludes awards, payroll, income tax, scheduling, demand, collection risk and actual-job tracking.
  • Treat the quote as a protected commercial starting point, then reconcile it with scope, exclusions and client value.

Frequently asked questions

How do I turn scoped task rows and project costs into a transparent fixed quote?

Move the base quote into a written proposal that states delivery scope, revision limits, contingency and approval terms.

Is contingency the same as profit?

No. Contingency is an allowance added to delivery cost before the target margin is applied.

Does this create contract terms?

No. It is an educational quote-reconciliation workflow, not a contract or legal document.

Which planning assumptions should I stress-test?

Compare a plausible alternative scenario and verify the decision-critical assumption that changes the plan most.
