A FEW THINGS TO KNOW

Clear from the start.

Need something more specific?
Ask Pure Knight ↗

How does the 14-day trial work?

Request the plan you would like to try. Pure Knight will arrange a trial workspace and confirm its start date, features and limits. Your 14 days start when the workspace is made available. No card details are collected on this site and no subscription starts automatically.

Does Starter include AI?

No. Starter focuses on manual estimating, the product library, customer and project management, and branded quotations. AI-assisted email and attachment processing is reserved for Professional and Business.

Which plan includes Sage or Xero?

Accounting exports are planned for Business only. They are not yet available and are not included in Starter or Professional. We will confirm exactly what is supported before offering this feature.

Can I purchase directly from the pricing page?

You can choose a plan here and send a purchase enquiry. Pure Knight will confirm pricing, terms and setup before payment. Automated online checkout and account activation are being prepared.

Is this designed for wetcast, semi-dry and GRC?

Yes. StoneFlow supports configurable materials, densities and pricing methods, including area and volume pricing. Your rates and review process stay under your company’s control. Complex profiles and technical exceptions still need estimator review.
