GOOD TO KNOW
Free Construction Tools: Frequently Asked Questions
Start with a free tool. Move to the app only when a connected workflow makes sense for you.
Still have a question?Can I use these tools without an account?
Yes. Start measuring, calculating or creating a document without signing up. Document generation and AI assistance have daily limits. The generators show the current limits and the extra allowance available with a free, confirmed account.
Which tool should I use if I already have measurements?
Use Measurements to Pricing. Enter areas, lengths, counts or room dimensions, apply your material and labour rates, then turn the results into a free quote. You do not need to upload a plan.
Open Measurements to PricingCan I measure a roofing, cladding or flooring plan?
Yes. The roof takeoff tool lets you upload a PDF or image plan, calibrate it against a known dimension, and measure areas and lengths. Check the scale and all measurements before relying on the result.
Open Digital TakeoffAre the example component prices real market rates?
No. The example libraries use fictitious prices so you can see how components work. Replace material, labour and waste allowances with your own rates before quoting a customer.
Can I make a quote, purchase order or invoice as a PDF?
Yes. Each generator lets you review your document, then print or save it as a PDF. A free, confirmed account removes QuoteCore+ document branding and provides a higher shared daily allowance.
Create a free quoteWhat is different about the paid QuoteCore+ app?
The free tools solve individual tasks. The paid app gives you saved pricing and component libraries, job records and a connected workflow for takeoffs, quotes, orders and invoices. Explore the demo for free before deciding whether the full app fits your business.
