No Slip

The product

What our users say

We used to spend Fridays building a deck that was out of date by Monday. Now the client sees what we see, when we see it. The conversations are different. We talk about delivery, not the report.

David HollowaySenior Planning Engineer, Catchment Civils

We had eight months of records nobody could argue with. The forensic module turned that record into a claim document for £2,500. Without No Slip we would have spent £85,000 to produce a weaker case retrospectively.

Sarah MitchellCommercial Director, Northern Infrastructure Group

We are not the kind of company that buys software with twenty features we will never use. No Slip does one thing properly. Our weekly cycle takes minutes now. That is the entire pitch.
