VAT, day rates, material markup, CIS deductions, all in one place. No sign-up needed.

Tip: UK tradespeople typically work 220 billable days after holidays and non-billable time. Overhead covers van costs, tools, insurance, and fuel. Typically 15–25%.

Most UK tradespeople mark up materials 20–40%. A 30% markup = 23% gross margin. Remember: markup and margin are different.

CIS (Construction Industry Scheme) applies to payments from contractors to subcontractors. CIS is deducted from labour only, not materials. Always verify your subcontractor's registration with HMRC.
