A profitable quote has to work in two views at once. The customer needs a clear price for a defined scope; the business needs to know whether that price covers the real cost of doing the work. If labour, materials, travel, subcontractors, and job-specific overhead are incomplete, polished wording cannot rescue the margin. The safest starting point is therefore the cost base, not the price a competitor might charge.
Build a complete cost base before choosing the price
Build the cost base from direct job costs you can defend. Material cost is the amount the business expects to pay, including delivery or waste where relevant. Labour cost is not only the employee's wage: payroll costs and other directly attributable employment costs may belong in the internal rate. Add subcontractors, equipment hire, permits, disposal, and travel when the job requires them. General overhead can be recovered through the rates or a documented pricing rule, but it should never disappear from the calculation by accident.
Markup and margin measure the same difference from different denominators. Markup is profit divided by cost; margin is profit divided by selling price. If a line costs 100 and receives a 25% markup, its selling price is 125 and its margin is 20%, not 25%. To reach a target margin, divide cost by one minus the target margin: a cost of 100 at a 25% target margin needs a selling price of 133.33. Choose one method as the team's working language and show both values during review so they cannot be confused.
Keep markup and margin mathematically distinct
Do not force one percentage onto every line. A product, an hour of specialist labour, rented equipment, and a subcontracted task carry different handling effort, warranty exposure, and risk. A quotation tool should let the estimator keep internal cost and customer price connected at line level, then roll them into section and quote totals. Fixed-price work and percentage-based adjustments can still be used, but the reviewer must be able to see what they do to the total margin.
Test discounts before approving them. A quote with a cost of 800 and a selling price of 1,000 has 200 of gross profit and a 20% margin. A 10% discount reduces the price to 900, but cost remains 800; profit falls to 100 and margin to about 11.1%. Tax should be calculated according to the applicable local rules and kept separate from the operating margin. The important control is one reproducible calculation order for costs, markups, discounts, deductions, and tax—not a total edited by hand at the end.
See what a discount does before approving it
The customer-facing quote should explain scope, quantities, prices, options, tax, validity, and conditions without exposing the business's internal cost or target margin. Internal notes should stay internal, while exclusions and assumptions that affect delivery should be visible. A customer preview is useful precisely because it separates commercial transparency from confidential pricing logic before the document leaves the business.
Show the customer clarity, not internal economics
Review profitability at the point where changes are still cheap. In Lavenity, costs, prices, markups, margins, discounts, GST, and optional work remain connected to the quotation structure, while the customer preview shows the outward-facing result. The goal is not to maximise every percentage. It is to produce a price the customer can understand and the business can deliver without discovering after the job that revenue never covered the work.
Test the calculation on one real service quote
Take a recent quote and rebuild its internal cost before looking at the selling price. Include materials, burdened labour, subcontractors, equipment, travel, disposal, and other direct job costs. Mark every estimate whose source is uncertain instead of replacing uncertainty with a round number.
For each major line, record cost, selling price, markup, and margin. Verify the relationship with the formulas: markup equals profit divided by cost; margin equals profit divided by selling price. Then reconcile the line results with the section and quotation totals so a fixed or percentage adjustment cannot bypass review.
Apply the largest discount a salesperson may approve and calculate the margin again before tax. If the result falls below the business's agreed floor, change the scope, price, or approval rule rather than hoping the job will be faster than expected. Save the tested structure as a reusable template only after a reviewer can reproduce every total.
Frequently asked question
Is a 25% markup the same as a 25% profit margin?
No. If cost is 100, a 25% markup produces a selling price of 125 and a 20% margin. A 25% margin on the same cost requires a selling price of 133.33. Markup divides profit by cost, while margin divides profit by selling price. A quotation workflow should display the distinction and recalculate it after discounts or other price changes.
