Construction Quote Calculator UK CIS

The problem: quoting from experience leaves money on the table

Most sole traders and micro construction firms quote from experience, a rough figure in their head that may or may not cover their actual costs. They win jobs at a loss, or lose jobs because they couldn't produce a professional quote document fast enough. A structured, itemised quote with a clear payment schedule wins more jobs and protects margin.

• Quoting a round number without knowing if it covers your actual material and labour costs
• Losing jobs to competitors who produce professional, itemised quote documents
• No payment schedule, clients drag payment out over weeks after the job is done
• CIS deduction obligations not properly factored into subcontractor quotes
