Budgeting & job costing

Construction budgeting & job costing software

Turn an estimate into a living budget. Edit labour rates, quantities, overheads and profit, use your own saved rate books, and see cost, selling price, profit and margin as separate, honest figures.

A quote is only the start. ConstructQS lets you keep the budget alive through the job — adjust prices as suppliers quote, track where the margin is, and reprice without losing your edits.

What you can edit

Labour, plant & fuel

Workforce numbers, hours, days, wage rates and employer on-costs; plant hire with or without operator, transport, fuel use and prices.

Quantities & rates

Every item’s description, quantity, unit and unit rate is editable, with line totals recalculated automatically.

Allowances

Editable preliminaries, overheads, contingency and profit — with markup and margin calculated and shown separately.

Your own rate books

Save your real rates and reuse them on every job; project overrides never overwrite your saved rates.

Cost, selling price, profit and margin — kept honest

ConstructQS follows the standard build-up: direct cost → preliminaries → overheads → contingency → total cost → profit → selling price (net) → VAT → gross → margin %. Markup and margin are different numbers and we calculate each correctly, so you always know your true position.
