Make a proper VAT invoice and download it as a PDF in about a minute. Handles the CIS domestic reverse charge. No sign-up, and nothing leaves your browser.

Getting paid

Construction retention calculator

How much retention is locked on each contract, the exact dates each half is due back (JCT, NEC, US retainage), and whether it's overdue.

Getting paid

Late payment interest calculator

Work out the statutory interest and compensation you're owed on an overdue commercial invoice, under the Late Payment Act.

CIS calculator

Work out the right Construction Industry Scheme deduction (20%, 30% or 0%) on a subcontractor payment, labour and materials split correctly.

Pricing

Markup vs margin calculator

Price a job from your materials and labour and see your real profit margin, so you stop confusing markup with margin and under-charging.

What to charge

Day rate calculator

Work out the day rate you need to hit your take-home, once overheads, tax and the days you can't actually bill are accounted for.

Did it pay

Job profit calculator

See the real profit and margin on a job once your own labour and every cost is counted, plus the profit per day that tells you if the work was worth taking.

Pricing labour

Hourly rate calculator

Build your hourly charge-out rate from an employee's wage, on-costs, productive hours and overheads, so you price labour to profit instead of guessing.

Construction

VAT reverse charge checker

Four questions and you know whether to charge VAT or apply the domestic reverse charge, with the exact wording for your invoice.
