Start with a reviewable delivery promise
Write the work in terms of deliverables, acceptance and boundaries. A website project might include an agreed set of templates, defined content responsibilities, one named approval contact and a stated review process. The label Website redesign is too broad to price reliably on its own.
List the inputs the client must provide and what happens if those inputs change. A price built around approved copy and a single decision-maker is not equivalent to a price that includes content creation and coordination across six stakeholders. The commercial model should describe these conditions in language the client can understand.

Estimate the cost of the whole delivery process
Break the work into discovery, production, project management, review, quality checks and handoff. Estimate effort by role when the difference matters, then multiply each role's hours by its applicable cost rate. Add project-specific external expenses. Record whether your rates include employment overhead so later reviews compare like with like.
Use previous project records as evidence, but adjust for the new scope and constraints. One unusually smooth engagement is a weak basis for a repeatable offer. If a major unknown controls the estimate, consider a separately scoped discovery phase rather than pretending the entire programme can already be priced precisely.
- Include coordination and feedback time that is necessary to deliver the promise.
- Check licences, subcontractors and production expenses for this engagement.
- Keep taxes and pass-through items explicit rather than hiding them in a labour estimate.
- Write down exclusions and assumptions beside the estimate.

Calculate a margin-based starting price correctly
The illustrative calculation below uses total direct delivery cost of $5,000 and a target contribution margin of 30%. Price equals cost divided by one minus the target margin: $5,000 ? 0.70 = $7,142.86. The contribution is $2,142.86, which is approximately 30% of the price.
Adding a 30% markup to the same $5,000 cost produces a $6,500 price. Its $1,500 contribution is about 23.1% of revenue. Neither calculation is inherently the correct commercial choice, but they answer different questions. State which one you are using. A margin at or above 100% does not produce a valid finite price with positive cost.
| Method | Calculation | Result |
|---|---|---|
| 30% contribution margin | $5,000 ? (1 ? 0.30) | $7,142.86 price |
| 30% markup | $5,000 ? 1.30 | $6,500 price |
| Margin on the markup price | $1,500 ? $6,500 | 23.1% contribution margin |

Choose a commercial model that matches the uncertainty
A fixed fee works best when the delivery boundary is understandable and the agency can judge the effort with reasonable confidence. It gives the client a clear price while leaving the agency responsible for delivering the agreed work. A detailed internal estimate remains useful even when the client never sees an hourly breakdown.
Time-and-materials work can fit a changing backlog when rates, prioritisation and approval rules are clear. A retainer can support a recurring need when the period, included service and capacity assumptions are explicit. Neither model eliminates scope management. An unlimited request queue and unlimited delivery capacity are different promises.
| Model | Define before quoting | Review during delivery |
|---|---|---|
| Fixed fee | Deliverables, review allowance, assumptions and acceptance | Remaining effort and scope changes |
| Time and materials | Rates, approval owner, billing cadence and any cap | Authorised effort and current priorities |
| Retainer | Period, service boundary, capacity and rollover terms | Recurring demand, effort and upcoming needs |

Test the number against capacity and risk
Check who can deliver the work in the proposed window. A financially attractive project can still be a poor commitment if it depends on people who are already fully allocated. Consider the effect on existing promises before assuming that the team will absorb the work.
Run a sensitivity check. If an additional 20 hours at $50 per hour are required on the $7,142.86 example, direct cost rises from $5,000 to $6,000 and contribution falls to $1,142.86, or 16%. This does not automatically mean raising the price. It may mean reducing an uncertain deliverable, conducting discovery or explaining a client choice before the agreement is signed.

Present choices the client can actually compare
If the proposed investment exceeds the available budget, change a meaningful part of the offer: deliver fewer templates, defer an integration, shorten the content scope or stage the rollout. Explain what each option includes and the consequence of the tradeoff. Do not quietly promise the original scope at a fee your delivery model cannot support.
Put the selected scope, fee, schedule assumptions, billing terms and approval process into the proposal. After acceptance, carry those decisions into the project brief and budget. A clear quote has limited value if the delivery team starts from an earlier draft or an undocumented sales conversation.

Review the quote after delivery, without hindsight shortcuts
Compare estimated effort with actual effort by meaningful workstream. Separate approved new work from original-scope variance and exceptional disruptions. Keep a note of the assumptions that were accurate as well as those that failed.
Update the estimating checklist when you find a repeatable omission. Use the next proposal to test whether that change improves clarity. Over time, the agency develops a stronger evidence base for pricing without claiming that any single formula can predict client behaviour or delivery complexity.
THE PRACTICAL DETAILS
Questions, answered.
Can I use a margin formula for value-based pricing?
It provides a cost-side check, not a complete value assessment. A value-based price still requires a credible client outcome, a delivery commitment and a commercial agreement. The formula helps you understand what the chosen fee can support.
Should I show the client my cost rates?
Not necessarily. Internal delivery cost and the client-facing selling model serve different purposes. Explain the work and commercial terms clearly without assuming that your internal cost structure must appear in every proposal.
Is a contingency allowance the same as profit?
No. An allowance for uncertain delivery effort anticipates possible cost. Contribution is what remains after the costs included in your model. Treating the same allowance as both cost protection and guaranteed profit double-counts it.
What if the client budget is below the calculated price?
Review scope, phasing, assumptions and delivery approach. If the required work cannot fit the budget responsibly, say so. A lower fee only works when the resulting commitment is still feasible.
Can Flowboard calculate the quote for me?
The project price calculator gives a transparent cost-and-margin scenario. Flowboard proposals can carry the agreed offer into the workflow. You remain responsible for the estimate, terms and client acceptance.
