Built for UK subcontractors Work through dates, notices, applications, variations, labour, cash flow and material quantities without sending project data anywhere. Choose a tool below and enter the facts from your own subcontract. Each tool answers a different question: calculate the timetable, check issued notices, draft a notice, calculate interest or build the application. Calculate the due date, payment-notice deadline, pay-less deadline and final date using editable contract periods and the England and Wales Scheme fallbacks. Clear purpose: Use this first when you need the full payment timetable from one valuation or relevant date. Check payment and pay-less notice timing against the signed subcontract or the editable England and Wales Scheme fallback periods. Clear purpose: Use this after notices have been issued to compare the actual dates with the contractual deadlines. Work out a contractual notice deadline and create a structured first draft recording the event, clause, effect and action required. Clear purpose: Use this to calculate a notice deadline and prepare a structured first draft for a specific event. Estimate simple daily interest on an overdue construction payment, with an optional statutory compensation amount for qualifying business debts. Clear purpose: Use this only for an overdue sum after entering the interest rate that actually applies. Build a cumulative application summary covering work, variations, materials on site, retention, previous certificates, deductions and VAT. Clear purpose: Use this to turn cumulative value, retention, deductions and previous payments into the current application total. Use these for material quantities, pricing a change or comparing forecast receipts with the total contract value. Choose a construction trade and calculate practical material quantities using editable assumptions for waste, coverage, pack sizes and fixings. Clear purpose: Use this to estimate order quantities for one selected trade, including waste and practical pack or fixing assumptions. Price labour, materials, plant, subcontractors and preliminaries with separate overhead, profit and risk allowances. Clear purpose: Use this to price a change from its direct labour, material, plant and subcontract costs before agreed additions. Compare forecast valuations and receipts with the total contract value using your own monthly figures or an approximate S-curve. Clear purpose: Use this for contract-level receipt timing and valuation progress. It deliberately excludes profit and cost forecasting. Daywork records actual daily resources, prolongation records time-related delay cost, and labour rate establishes an hourly selling rate. They are not interchangeable. Calculate labour, material and plant daywork with editable uplifts and a clear total ready to transfer to the signed record. Clear purpose: Use this for actual daily labour, material and plant records. It is not a labour selling-rate calculator. Estimate time-related site costs for a delay using weekly management, welfare, hire, utilities, insurance and other preliminaries. Clear purpose: Use this for time-related site overhead caused by delay. It is not a daywork or trade-rate build-up. Turn annual employment cost, non-productive time, business overhead and target profit into a sustainable hourly charge-out rate. Clear purpose: Use this to establish an hourly selling rate from annual employment and business cost. It is not a project valuation.Straightforward QS tools for the jobs you deal with every week
